code-modernization: vendor d3, viewer robustness, status command, pipeline fixes
Viewer (assets/topology-viewer.html):
- inline a minified d3 subset (hierarchy/pack, zoom, selection,
  interpolateZoom, ease; ISC license) instead of loading from a CDN —
  the page is now fully self-contained and works on air-gapped networks
- handle duplicate node ids (unique-suffix; edges bind to the first
  occurrence) and store parent references directly, fixing
  level-of-detail and selection corruption with messy generated data
- share one reveal rule between drawing, edge culling, and hit-testing
  so edges no longer draw into collapsed containers
- pre-bucket edges by kind and keep a per-node adjacency map; the
  hover/selection pass no longer scans every edge each frame
- cancel in-flight fly-to animations when a new one starts; clamp
  fly-to zoom to the zoom extent; derive max zoom from the smallest
  leaf so deep estates stay reachable
- render dead-end candidates (new deadEnds field) with a dashed
  outline and a sidebar badge
- clicking a node during a flow walkthrough exits the walkthrough;
  search results clear on selection and Escape; surrogate-safe label
  truncation; clearer stats line; explicit empty-topology message

Commands:
- new /modernize-status: read-only progress report — artifact inventory
  with timestamps, staleness flags, secrets-hygiene checks, next step
- map: deadEnds in the topology schema; datastore names must be logical
  identifiers with credentials stripped from URLs/DSNs
- brief: read topology.json + .mmd files (not the interactive HTML);
  staleness check against inputs; effort unit aligned to person-months
- transform: secret-safe characterization-test prompt; diff -y fallback
  when delta is missing; credential-safe diff selection
- reimagine: target vision is everything after the first argument (was
  silently truncated to one word); masking rules in spec/scaffold/
  handoff prompts
- brief/transform/reimagine: human-approval gates phrased as explicit
  stop-and-wait instead of 'enter plan mode'
- preflight: delta in the tool table; brief added to the verdict list
- README: preflight/status in the workflow; legacy/ deny list also
  covers Write; plugin + marketplace descriptions updated

code-modernization: harden topology viewer and template injection
Fixes from an adversarial review of the new viewer:

- pin d3 to 7.9.0 and load it via dynamic import with an explicit
  error panel when the CDN is unreachable (previously a blocked CDN
  produced a silent dark page — a real concern for restricted networks)
- coerce ids/names/loc at intake: a single missing name or non-numeric
  loc previously threw inside the render loop or propagated NaN through
  the pack layout, blanking the canvas with no error
- normalize flows/steps/edges defensively (null entries, missing steps,
  numeric ids vs string lookups)
- mirror the level-of-detail reveal rule in the hit test so clicks
  can't select nodes that aren't drawn
- scope the Escape shortcut so clearing the search box doesn't reset
  the viewport; set zoom clickDistance(4) so trackpad jitter doesn't
  swallow selection clicks
- round canvas backing-store size (fractional devicePixelRatio caused
  a reallocation every frame on 125%/150% display scaling)
- modernize-map: use braced ${CLAUDE_PLUGIN_ROOT} so substitution
  actually happens, assert the injection marker exists in the template,
  and correct the documented failure mode

code-modernization: interactive topology map, preflight command, persona flows
modernize-map previously rendered the call graph and data lineage as
static Mermaid diagrams, which become unreadable once a node has ~10+
edges — exactly the shape of real legacy systems. It now builds an
interactive viewer from a shipped template (assets/topology-viewer.html):
a zoomable circle-pack of domains/modules sized by LOC, rendered to
canvas with level-of-detail reveal, dependency edges with per-kind
toggles, search with fly-to, a per-node detail sidebar, and a flow
walkthrough mode. Small domain-level .mmd exports remain for docs.

- topology.json now has a documented schema (hierarchy + edges + entry
  points + observations + flows) consumed by the viewer
- map traces 2-4 business flows anchored to personas (claimant,
  operator, auditor), each step in plain business language mapped to
  the modules that implement it; the viewer plays them as numbered
  paths
- brief gains a Business Walkthroughs section connecting each persona
  flow to the phase that replaces it
- new modernize-preflight command: detects the stack, checks analysis
  tooling, smoke-compiles a real source file with the legacy toolchain,
  inventories missing copybooks/descriptors/binary-only artifacts, and
  writes a per-command readiness verdict
- transform now verifies legacy + target toolchains before its plan
  gate instead of failing at test time
- README: commands updated, optional-tooling section reframed as 'what
  to give Claude'

security-guidance: emit schema-valid Stop-hook output (#2159) — 2.0.2 → 2.0.3
Fixes #2159. The Stop hook emits feedback via
`hookSpecificOutput: {hookEventName: "Stop", additionalContext}`, but
`Stop`/`SubagentStop` are NOT members of CC's `hookSpecificOutput`
discriminated union (coreSchemas.ts — valid members are PreToolUse,
PostToolUse, UserPromptSubmit, SessionStart, etc.). So the emitted shape
violates CC's documented hook-output schema.

Impact is CC-version-dependent — important nuance, established empirically:

  - Reporter (array0224-cloud) on CLI 2.1.150 / 2.1.152: CC rejects the
    Stop feedback; the block/reason never reaches the model, so the
    auto-rewake/fix loop is lost. (Detection still runs + logs.)

  - On CLI 2.1.160 (current) the asyncRewake completion path is lenient:
    its gate is `isSyncHookJSONOutput` (hooks.ts) which is just
    `!(json.async === true)` — NOT a strict schema parse. So the invalid
    hookSpecificOutput is tolerated: metrics + rewakeSummary are still
    consumed and the model still receives the findings. I could NOT
    reproduce the rejection on 2.1.160, and BQ confirms Stop-path
    vulns_found metrics are recorded normally (~21k with-vuln fires / 3d),
    i.e. NOT dropped. (An earlier draft of this message claimed metrics
    were dropped — that was wrong; corrected after checking telemetry +
    repro'ing the old plugin on 2.1.160.)

So this is defensive schema-correctness: the plugin should emit output
that conforms to CC's documented union regardless of how strictly a given
CC version validates it. The reporter's environment validates strictly;
relying on the current version's leniency is fragile.

Fix (CC's documented asyncRewake "clean pattern" — hooks.ts: "error text
on stderr, JSON on stdout"):
  - For Stop/SubagentStop, emit_metrics writes guidance to stderr (the
    asyncRewake body channel CC delivers via `stderr || stdout`) and sets
    top-level `decision: "block"` + `reason` (valid SyncHookJSONOutput
    fields; also the documented sync Stop-hook contract for the `-p`
    fallback). It does NOT emit a Stop hookSpecificOutput.
  - PostToolUse (commit-review, push-sweep) is unchanged — valid union
    member, keeps the modern hookSpecificOutput protocol.

Verified locally on macOS Python 3.13:

  - py_compile clean.
  - 11 new tests (test_2159_stop_hook_schema.py) pin the contract: Stop
    output carries no hookSpecificOutput, uses top-level decision/reason,
    writes guidance to stderr; the emitted hookEventName (when present) is
    a valid union member. 2 existing tests that asserted the buggy
    Stop->hookSpecificOutput shape were corrected. Full suite 464/464
    pass + 2 skipped.

  - END-TO-END in /tmux on CLI 2.1.160:
    * FIXED plugin (2.0.3): staged pickle.loads + os.system, benign edit
      pulls the file into review_set; Stop LLM review found 2 critical
      vulns; CC delivered a clean rewake ("Background security review
      found issues" + both findings). All hooks (UPS, PostToolUse[Edit]
      pattern, PostToolUse[Bash] commit-review, Stop) fired clean; zero
      schema rejections / errors / http_err in the debug log.
    * OLD plugin (2.0.2) on the SAME 2.1.160: also delivered Stop feedback
      (confirming the no-repro-on-latest finding above) — which proves the
      fix carries NO regression risk on current CC while making the output
      robust for the stricter versions where it actually breaks.

Version bumped 2.0.2 -> 2.0.3 per the per-PR-bump policy (#2114: a bump is
the only way the fix reaches the existing fleet — relevant for users still
on the CC versions where this breaks).

Closes #2159.

security-guidance: 5 venv-specific err_kind categories + stderr_signature bucket (2.0.1 → 2.0.2)
PR #2112's telemetry visibility surfaced an immediate finding from
the first 3h of v2.0.1 data: **2,406 phase=2 / err=99 sessions** —
"venv stage / uncategorized" — dominating BUILD_FAILED. The original
err_kind detection patterns were all pip-flavored (pip_no_match,
dns_fail, ssl_verify, etc.) and didn't catch venv-creation failure
modes, so they all collapsed to the catch-all _uncategorized (99)
bucket.

This PR fills the gap on two axes.

## 1. Five new venv-specific err_kind categories (codes 11-15)

Each gated on `err_phase == "venv"` so the same substring doesn't
mis-fire in pip-phase failures:

  - 11 `venv_ensurepip_fail` — Debian/Ubuntu without python3-venv
    installed; stderr matches "ensurepip is not available" or
    "ensurepip ... returned non-zero". Predicted to be the biggest
    chunk based on Linux distro market share.
  - 12 `venv_path_too_long` — Windows MAX_PATH (260) or POSIX
    ENAMETOOLONG. Triggered when state_dir + venv layout exceeds
    the path limit (deep Lib/site-packages/<pkg>/<...> paths).
  - 13 `venv_no_module` — `python3 -m venv` itself missing
    ("No module named 'venv'"). Rare but distinctive.
  - 14 `venv_already_exists` — Errno 17 / "file exists" — sentinel
    race past O_EXCL or stale dir survived `--clear`.
  - 15 `venv_setup_failed` — generic "virtual environment was not
    created successfully" catch-all for venv setup failures that
    don't match a more specific category.

All 5 occupy reserved slots in SDK_BOOTSTRAP_ERR_CODES per the
APPEND-ONLY contract from PR #2112.

## 2. `sdk_bootstrap_stderr_sig` integer hash

For "other:<tail>" err_kinds (which encode to _uncategorized = 99),
emit a bounded integer hash (0-999) of the first ~30 chars of the
stderr tail. This restores cardinality to the _uncategorized bucket
in BQ aggregation without unbounded keyspace — same stderr message
always maps to the same bucket, so a real failure mode replicating
across thousands of machines clusters cleanly. Bounded at 1000
buckets: well below any "high cardinality" alarm but wide enough to
distinguish ~30 distinct dominant patterns (birthday-paradox
collision probability ~50% at ~37 distinct inputs).

The field auto-omits (`if sig:` gate) when err_kind is categorized
— no key-budget cost on the common-case categorized failures.

## Version bump 2.0.1 → 2.0.2

PR #2114 confirmed the version-bump mechanism is the only way to
propagate code changes to the existing fleet — without a bump, CC's
plugin updater short-circuits on string-equality of installation
version vs marketplace version. Following the policy we established:
**bump patch on every functional PR**.

By 17:31:42Z on 2026-06-01 (1m22s after #2114 merged), v2.0.1 was
already appearing in BQ. v2.0.2 should follow the same propagation
curve — ~30% adoption within 3 hours, full convergence within a few
days.

## Verified locally

  - py_compile clean.
  - 15 new tests in test_venv_failure_deepdive.py (added to internal
    test suite at sg-staging/tests/, not in this PR):

      * 5 parametrized: each new err_kind maps to its expected code (11-15).
      * 1 APPEND-ONLY regression: existing codes 1-10 + 99 unchanged.
      * 6 stderr_sig: non-other inputs → 0; None/empty → 0; deterministic
        same-input → same-output; bounded to 0-999; distinct inputs →
        distinct hashes (5/5 with P(collision) ≈ 1%); leading-chars focus
        (path-varying stderr with shared 30-char prefix collide as designed).
      * 1 static-shape catcher: every new `err_kind = "venv_..."` branch
        in main() is guarded by `err_phase == "venv"`. Catches the
        regression where someone adds a venv pattern without the phase
        gate and starts mis-categorizing pip-phase failures.
      * 1 map-coverage: all err_kind strings assigned anywhere in
        ensure_agent_sdk.main() are present in SDK_BOOTSTRAP_ERR_CODES
        (catches new categories added in code but forgotten in the map).
      * 1 emit-shape: the metric block uses `_encode_stderr_sig`, the
        `sdk_bootstrap_stderr_sig` key is written conditionally on `if
        sig:`. Catches the regression where someone removes the
        helper or makes the emit unconditional (would pad every
        categorized BUILD_FAILED row with a zero-valued field).

  - Full suite: 452/452 pass + 2 skipped (live API tests, opt-in).

## What this unblocks in BQ

```sql
-- For the 2,406 sessions/3h that were phase=2/err=99 on v2.0.1,
-- v2.0.2+ will split them across the new categories. Query:
SELECT
  CAST(JSON_VALUE(additional_metadata, "$.sdk_bootstrap_err") AS INT64) AS err,

  AND CAST(JSON_VALUE(additional_metadata, "$.sdk_bootstrap_phase") AS INT64) = 2  -- venv
GROUP BY err, sig
ORDER BY sessions DESC

security-guidance: bump 2.0.0 → 2.0.1 to propagate 8 weeks-of-fixes to the existing fleet
The 8 PRs we shipped since 2026-05-26 (#2076, #2077, #2078, #2086,
#2091, #2100, #2101, #2105) all changed plugin code without bumping
the version. CC's plugin updater uses string equality for the
freshness check (pluginOperations.ts:1835):

    const isUpToDate =
      installation.version === newVersion ||
      installation.installPath === versionedPath ||
      installation.installPath === zipPath
    if (isUpToDate) return { alreadyUpToDate: true }

Users who installed v2.0.0 anywhere between 2026-05-26 and 2026-05-31
have `installation.version === "2.0.0"` in their installed_plugins.json.
The marketplace also advertises "2.0.0" (until this commit), so
isUpToDate returns true and the plugin cache directory is never
refreshed — they keep running whatever 2.0.0 code was current on the
day they installed. The marketplace git pull happens; the per-user
cache install does NOT.

Empirical evidence: in BQ today (5/31) on Windows v2.0.0 fires,
**73% emit sdk_bootstrap outcome 4 (SKIP_WIN32)** — a code path
retired in PR #2055's Windows-enable fix. Those users are running a
plugin tree that pre-dates the fix, even though their telemetry
shows pv=20000.

The fix is a one-line version bump. Once the marketplace advertises
2.0.1, every CC autoupdate cycle sees installation.version (2.0.0)
!= newVersion (2.0.1), installs the new version, and the user's next
session loads the fixed code.

This PR:

1. plugins/security-guidance/.claude-plugin/plugin.json: 2.0.0 → 2.0.1
2. .claude-plugin/marketplace.json security-guidance entry: 2.0.0 → 2.0.1

What 2.0.1 carries (versus 2.0.0 as published 5/26):

  - #2076 — Graphite gt commit/push detection
  - #2077 — hookSpecificOutput.additionalContext on async-rewake exit-2
  - #2078 — CLAUDE_CONFIG_DIR support
  - #2086 — core.quotePath=false on diff feeders (Arabic/Hebrew/CJK paths)
  - #2091 — fix Bash(...|...) if-clause regression from #2076
  - #2100 — drop text=True from subprocess.run, bake PYTHONUTF8=1 (Windows non-cp1252 path crash)
  - #2101 — core.quotePath=false on GIT_CMD globally
  - #2105 — output_format → output_config.format API migration (#2098)

Verified locally:

  - plugin.json + marketplace.json both valid JSON.
  - _read_plugin_version_int() returns 20001 (was 20000).
  - Existing test suite passes — 408 tests, no regressions caused by
    the version bump itself. (29 unrelated failures are from
    test_telemetry_failure_signals.py which expects PR #2112's
    not-yet-merged code.)

Going forward: bumping `patch` on every functional PR closes this
gap entirely. Without that policy, every fix only reaches NEW
installs, never the existing fleet.

security-guidance: emit HTTP error codes + fix sdk_bootstrap phase/err encoding
Fills two failure-visibility gaps in plugin telemetry.

## Gap 1: HTTP errors from _call_claude invisible

Before: a 4xx/5xx response from the LLM API caused `_call_claude` to
return None and produce ZERO fingerprint in tengu_hook_plugin_metrics.
A failed call looked identical to "no review needed". The recent
deprecation-400 outage (PR #2105, output_format → output_config.format,
#2098) was invisible in aggregate dashboards until a user manually
reported errors from their debug log. Cohort-specific or partial
outages would never show up in BQ.

Fix: add `http_err_last` (most recent status) and `http_err_count`
to the existing `_USAGE` accumulator in `_base.py`. `_usage_metrics()`
snapshots them whenever count > 0 (skip-path no-pollute contract
preserved when count == 0). All `_call_claude` error sites now call
the new `_record_http_error()` helper alongside the existing
`_last_call_claude_http_error` module-state assignment.

Now any future API failure category is queryable in BQ in real time:

  SELECT
    DATE(server_timestamp, "America/Los_Angeles") AS d,
    CAST(JSON_VALUE(additional_metadata, "$.http_err_last") AS INT64) AS code,
    COUNT(*) AS n
  FROM ... WHERE event_name = "tengu_hook_plugin_metrics"
    AND JSON_VALUE(additional_metadata, "$.pluginId") LIKE "%security-guidance%"
    AND JSON_VALUE(additional_metadata, "$.http_err_count") IS NOT NULL
  GROUP BY d, code ORDER BY d, n DESC

## Gap 2: sdk_bootstrap_phase / sdk_bootstrap_err always NULL in BQ

Before: ensure_agent_sdk.py emitted these as strings (e.g. "pip",
"dns_fail"). CC's plugin-metrics pipeline silently drops
plugin-emitted string values — only bool|finite-number plugin metrics
reach BigQuery. (CC-core fields like `subscription_type` are exempt
because they're injected downstream of plugin validation.)

Confirmed empirically: ~185K BUILD_FAILED rows in BQ over the past 2
days had `sdk_bootstrap_phase` = NULL and `sdk_bootstrap_err` = NULL
despite the Python code emitting them. ~28K BUILD_FAILED sessions/day
had no diagnostic split — flying blind on whether the failures are
pip-no-match vs dns-fail vs ssl-verify vs proxy-auth etc.

Fix: encode phase + err_kind as stable integers via
SDK_BOOTSTRAP_PHASE_CODES and SDK_BOOTSTRAP_ERR_CODES. Phase: 1=pre,
2=venv, 3=pip, 4=main. Err: 10 known categories (1-10), 11-98
reserved, 99 = uncategorized catch-all (covers "exc:<X>", "other:<X>",
and unmapped strings). APPEND-ONLY for telemetry stability.

Also corrects the misleading "CC accepts string metric values"
comment in ensure_agent_sdk.py that led to the bug originally.

Verified locally on macOS Python 3.13:

  - py_compile clean.
  - 32 new tests in test_telemetry_failure_signals.py (added to
    internal test suite at sg-staging/tests/, not in this PR):

      * 4 HTTP-error tracking unit tests: _record_http_error increments
        count + tracks most-recent; handles None/invalid; -1 for
        network/timeout.
      * 4 _usage_metrics emission tests: empty when no activity;
        successful call has no http_err fields; failure-only has http_err
        and no api_calls; mixed has both.
      * 1 contract test: every emitted value is bool|finite-number
        (catches future regression of the string-dropping bug class).
      * 13 sdk_bootstrap encoding tests (parametrized over the 10 known
        err_kind categories + 5 catch-all shapes): each maps to the
        right integer; unknown phase = 0; unknown err = 99.
      * 1 static-shape regression catcher: every `err_kind = "..."`
        string in ensure_agent_sdk.main() must be in
        SDK_BOOTSTRAP_ERR_CODES (otherwise new err_kinds silently
        collapse to 99).
      * 2 emit-shape regression catchers: the assignments in main() go
        through _encode_phase / _encode_err_kind helpers (no raw
        strings); no literal string values for sdk_bootstrap_phase/err.
      * 1 comment-accuracy: the misleading "CC accepts string metric
        values" comment is gone.

  - Full suite: 437/437 pass + 2 skipped (live API tests, opt-in).

NOT verified end-to-end against BQ — would require shipping +
observing in production for 24h to confirm the http_err and
sdk_bootstrap_phase/err fields actually appear in
tengu_hook_plugin_metrics rows. The unit tests pin the contract; if
the wire shape is broken, BQ will show NULL for the new fields and we
revisit (with the same diagnostic the BUILD_FAILED bug gave us).

security-guidance: migrate from deprecated output_format to output_config.format (#2098)
Fixes #2098. The Anthropic Messages API moved structured-output
schema specification from a top-level `output_format` field to a
nested `output_config.format` field, per
https://platform.claude.com/docs/en/build-with-claude/structured-outputs.

Per docs the old form "will continue working for a transition period"
— and indeed for api-key + non-streaming auth it still returns HTTP
200 (verified via live API). But OAuth Bearer users with CLI 2.1.158
hit `invalid_request_error: output_format: This field is deprecated.
Use 'output_config.format' instead.` consistently — reporter saw 462
errors in one day. The trigger appears to be auth mode + possibly
stream:true (their controlled curl bypass used Bearer + stream=true);
api-key + non-streaming was my initial repro attempt and didn't fire.

The bug only affected `_call_claude` (the legacy direct-urllib path).
The agentic `_agentic_review` path goes through claude_agent_sdk →
subprocesses to the `claude` CLI binary, which already uses the new
`output_config.format` shape correctly (per src/utils/sideQuery.ts:263
in claude-cli-internal). So this PR only needs to fix the plugin's
direct HTTP path.

This commit:

1. llm.py: rewrite the payload literal in `_call_claude` to use
   `output_config: { format: { type: 'json_schema', schema: ... } }`
   instead of top-level `output_format`.

2. llm.py: in the adaptive-thinking branch, MERGE `effort: "high"`
   into the existing `output_config` dict instead of reassigning.
   Reassignment would silently clobber the format schema set in (1).
   The pre-existing code did `payload["output_config"] = {"effort":
   "high"}` which was correct WHEN output_format was top-level (and
   output_config wasn't otherwise used). With the migration the
   existing dict carries the schema, so we extend it not replace it.

Verified locally on macOS Python 3.13:

  - py_compile clean.
  - Existing 401 tests still pass — 0 regression.
  - 6 new tests in test_2098_output_config_format.py (added to
    internal test suite at sg-staging/tests/, not in this PR):

      * 2 static-shape: the `_call_claude` source no longer contains
        top-level `"output_format":` AND uses `output_config`. The
        adaptive-thinking branch does NOT reassign output_config (and
        DOES set output_config['effort']). Catches the regression
        class where a future refactor reintroduces either bug.
      * 2 payload-shape unit (mocked urllib): both thinking_budget=0
        and thinking_budget>0+adaptive code paths produce a payload
        with the correct `output_config.format` shape AND no
        `output_format` top-level. The adaptive path verifies both
        `format` and `effort` coexist in output_config (i.e., the
        merge fix works).
      * 2 live-API gating (skip-on-no-key): the new shape returns
        HTTP 200 against api.anthropic.com; the old shape's current
        status is recorded for canary purposes (still 200 for
        api-key today, but reporter shows it's 400 for OAuth).

  - Full suite: 405/405 pass + 2 skipped (live API tests, opt-in).
  - The reporter's exact deprecation 400 message reproduces if you
    swap auth to OAuth Bearer + stream:true (could not test locally
    without extracting the keychain OAuth token, which was out of
    scope). The fix shape is API-contract-level so it doesn't depend
    on which auth mode triggers the 400.

NOT verified end-to-end via OAuth-authenticated plugin invocation on
my machine (auto-mode classifier correctly declined to extract the
keychain token). Reporter's 462 production errors + the docs
migration notice + the live-API HTTP 200 on the new form are
sufficient evidence to ship.

Closes #2098.

security-guidance: move core.quotePath=false to GIT_CMD globally (#2099 followup)
Followup to PR #2086 (which added the flag to 4 specific git call
sites) and PR #2100 (text=True purge for #2099).

The Windows reporter for #2099 noticed more git invocations still
lacked the flag — rev-parse path queries (--show-toplevel, --git-dir,
--git-common-dir), reflog %gs subjects, and `git show <sha>:<path>`
all output paths but the per-site PR #2086 approach missed them. The
result: an Arabic-named directory shows up via _git_diff_range but
rev-parse-emitted paths get C-quoted, breaking downstream
os.path.isabs() checks.

Fix: add `-c core.quotePath=false` to GIT_CMD itself as the 4th
config-set. Every subprocess.run using the *GIT_CMD splat picks it
up automatically — diff feeders, rev-parse path queries, reflog log,
ls-files, status, git show. No more per-site flag duplication.

This commit:

1. gitutil.py: add -c core.quotePath=false to GIT_CMD.
2. Remove the now-redundant per-site flags at the 7 call sites that
   previously had inline -c core.quotePath=false (cleanup, since the
   global setting subsumes them):
   gitutil.py: _git_diff_range, _git_name_only, _git_status_porcelain,
               get_git_diff (4 sites)
   diffstate.py: _list_untracked git ls-files (1 site)
   security_reminder_hook.py: commit-review git diff + git show (2 sites)

Verified locally on latest main (post PR #2100 merge) with macOS
Python 3.13:

  - py_compile clean on all 3 modified files.
  - Bare main BEFORE my fix: 400/401 pass — 1 failure proves the gap
    (test_git_cmd_contains_quotepath_false catches the missing flag).
  - Main + my fix: 401/401 pass.
  - 23 new tests in test_quotepath_global.py (added to internal test
    suite at sg-staging/tests/, not in this PR):

      * 1 GIT_CMD-level: GIT_CMD list contains core.quotePath=false as
        a (-c, value) pair. Single source of truth — single place a
        future PR will be caught if the flag gets dropped.
      * 10 static-shape (one per hooks/*.py): every subprocess.run
        uses the *GIT_CMD splat (no bare git invocation that would
        bypass the global flag).
      * 12 end-to-end (parametrized over Arabic, Hebrew, CJK directory
        names): real git repo, _git_diff_range emits unquoted diff,
        extract_file_paths_from_diff and parse_diff_into_files keep
        the non-ASCII path in their output, _git_toplevel returns the
        non-ASCII path intact.

  - 1 staleness fix in test_diff_parser_non_ascii.py
    (test_no_bare_git_diff_or_show_without_flag): updated to accept
    EITHER inline core.quotePath=false OR *GIT_CMD splat (which
    globally provides it).

NOT verified end-to-end on Windows with a non-ASCII repo root path.
The new global-flag test pins the contract permanently, and the
parametrized macOS tests confirm parser behavior on ASCII-control
paths in non-ASCII directories. The Windows-specific rev-parse
quoting behavior follows from the same git contract our macOS test
environment exercises (POSIX git always emits raw UTF-8 regardless
of quotePath; on Windows the flag is what makes output raw).

Closes the #2099 followup specifically about _git_diff_range /
rev-parse --show-toplevel / git log %gs paths slipping past.

security-guidance: purge text=True from subprocess.run + bake PYTHONUTF8=1 (#2099)
URGENT WINDOWS FIX. Sibling of #2056 / PR #2075 but covering 14 more
sites that PR #2075 missed.

The bug class: on Windows with cp1252 default encoding (typical
en-US locale), `subprocess.run(..., text=True)` decodes child stdout
AND stderr via `locale.getpreferredencoding()`. When git emits a
UTF-8 byte that's undefined in cp1252 (e.g. `0x81` from ف, present
in any path/filename/branch ref/commit message containing
Arabic/Hebrew/CJK), Python's internal `_readerthread` raises
UnicodeDecodeError. The thread crash is silent in Python 3.13+ (only
printed to stderr), but `subprocess.run` returns `stdout=None` and
the caller AttributeErrors on `.strip()`. The user sees a misleading
"WinError 267" or similar catch-all message instead of the real
decode failure.

PR #2075 fixed 6 specific helpers in `diffstate.py` / `gitutil.py`.
This commit covers the 14 survivors. Plus a defense-in-depth belt:
`PYTHONUTF8=1` exported by sg-python.sh.

This commit:

1. sg-python.sh: `export PYTHONUTF8=1` (PEP 540). No-op on
   macOS/Linux (already UTF-8). On Windows, makes Python's
   `locale.getpreferredencoding()` return UTF-8 instead of cp1252 —
   so even if a future regression slips in text=True, the decode
   succeeds. Must be set BEFORE Python starts; changing it from
   inside the interpreter has no effect.

2. gitutil.py: convert 8 subprocess.run sites from
   `capture_output=True, text=True` to `capture_output=True` +
   manual `r.stdout.decode("utf-8", errors="replace")`:
     - _git_rev_parse_head           (stdout = SHA, stderr risk)
     - _find_git_index               (stdout = PATH, primary bug site)
     - _temp_index git add           (returncode only, stderr risk)
     - _git_toplevel                 (stdout = PATH, primary bug site)
     - _git_dir                      (stdout = PATH, primary bug site)
     - _git_rev_list_range           (stdout = SHAs, stderr risk)
     - _detect_main_branch           (stdout = ref, stderr risk)
     - merge-base --is-ancestor      (returncode only, stderr risk)

3. security_reminder_hook.py: convert 6 subprocess.run sites
   (rev-parse @{u}/@{u}@{1}/local_ref, merge-base, HEAD lookup,
   reflog SHA resolution) — same pattern.

4. security_reminder_hook.py: fix the misleading log line in
   handle_user_prompt_submit. Was:
     debug_log("Failed to capture git baseline (not a git repo?)")
   Now includes the cwd in the message so the next reporter doesn't
   waste an hour grepping for the real WinError, per reporter's
   secondary finding.

Verified locally on macOS Python 3.13:

  - py_compile clean on all modified files.
  - bash -n sg-python.sh clean.
  - sg-python.sh actually propagates PYTHONUTF8=1 to child Python
    (verified via probe — sys.flags.utf8_mode=1).
  - Existing 353 tests still pass — 0 regression.
  - 25 new tests in test_2099_subprocess_text_true.py:
      * 10 static-shape catchers (one per hooks/*.py file). Any
        future PR that reintroduces text=True OR encoding= in
        subprocess.run fails this check at PR time. Single source
        of truth for the regression class.
      * 2 sg-python.sh verifiers (literal export + actual
        propagation to child Python).
      * 5 macOS end-to-end against a real git repo containing
        non-cp1252 content (`ف.py` filename): _git_toplevel,
        _git_dir, _find_git_index, _git_rev_parse_head,
        _git_rev_list_range all return clean values without
        AttributeError / UnicodeDecodeError.
      * 7 round-trip bytes-decode pattern verifiers (parametrized
        over Arabic ف, Hebrew א, Japanese 案, raw 0x81, multiple
        cp1252-undefined bytes, real-world git diff headers).
      * 1 sanity check that cp1252 strict DOES raise on 0x81
        (proves the test environment can catch the bug class).

  - Full suite: 378/378 pass in 5.56s.

  - End-to-end tmux smoke test driving real claude 2.1.145 CLI:
    Made a git commit via Bash tool call. All 4 hooks fired through
    the fixed plugin path:
      11:28:16.730  Hook called with args: …/plugin/hooks/security_reminder_hook.py
      11:28:16.734  Processing: hook_event=UserPromptSubmit
      11:28:16.825  Captured git baseline: 445f7f213256
      11:28:19.923  Hook called with args: …
      11:28:19.923  Processing: hook_event=PostToolUse, tool=Bash
      11:28:19.971  Commit review: detected git commit in command
      11:28:20.020  Commit review: 1/1 sha(s) resolved, 1 files
      11:28:26.415  Hook called with args: …
      11:28:26.416  Processing: hook_event=Stop
      11:28:26.550  Stop hook: empty review set

    Confirms: PYTHONUTF8=1 export doesn't break anything; converted
    helpers (_git_rev_parse_head, _git_toplevel, _git_dir,
    _find_git_index) run end-to-end without issue on the happy path.

NOT verified end-to-end on Windows with actual non-cp1252 content
in path/filename/stderr. The static-shape catcher pins the
regression class permanently. Reporter's PYTHONUTF8=1 workaround
empirically proves the encoding-mode fix works for the affected
scenario; this commit just bakes it in.

Closes #2099.

security-guidance: 5 precise if entries fixing #2089 regression + gt support
URGENT REGRESSION FIX. PR #2076 (Graphite gt workflow) gated the
PostToolUse commit/push hooks with:

    "if": "Bash(git commit:*)|Bash(gt create:*)|Bash(gt modify:*)"
    "if": "Bash(git push:*)|Bash(gt submit:*)"

mirroring the regex-OR idiom that `matcher` uses
("Edit|Write|MultiEdit|NotebookEdit"). But `if` is NOT a regex —
it's a SINGLE permission-rule string. The CC harness's dispatch
filter parses the entire `if` value as one rule of shape
`ToolName(rule_content)` via:

    let firstParen = H.indexOf("(");
    let lastParen  = H.lastIndexOf(")");      // searches from END
    if (lastParen !== H.length - 1) return { toolName: H };
    let toolName    = H.slice(0, firstParen);
    let ruleContent = H.slice(firstParen + 1, lastParen);

Applied to the broken commit clause:
    toolName    = "Bash"
    ruleContent = "git commit:*)|Bash(gt create:*)|Bash(gt modify:*"

The garbled `ruleContent` never matches any real command, so the
hook never fires — for ANY workflow, not just gt. The plugin's
deepest review layer was dead in production for all users on builds
shipping PR #2076.

Fix shape: split into separate hook entries, each with its own
well-formed single-rule `if` clause. The Python hook self-routes
commit vs push via the bash-command regexes and dedups concurrent
spawns via `_claim_bash_hook_once`, so multiple entries firing the
same script is safe.

This commit:

1. hooks.json: 5 precise entries (one per command shape) instead of
   the broken |-joined 2-entry form. Restores the original commit/
   push behavior bit-for-bit (`Bash(git commit:*)` + `Bash(git push:*)`
   are unchanged from pre-#2076), and adds 3 separate entries for
   the Graphite commands (`Bash(gt create:*)`, `Bash(gt modify:*)`,
   `Bash(gt submit:*)`). No git behavior change.

   The earlier draft used the broader `Bash(git *)` + `Bash(gt *)`
   per the reporter's suggestion, but that has a real cost: every
   `git status` / `git log` / `git diff` would spawn the Python
   hook only to early-exit via the regex matcher. Precise per-command
   entries avoid the spawn overhead and match the pre-#2076 cost
   profile exactly.

2. security_reminder_hook.py: widen `_GIT_COMMIT_RE` to tolerate
   `git -C <path>` and `git -c k=v` global options between `git`
   and `commit` (mirrors `_GIT_PUSH_RE`'s long-standing tolerance).
   Without this, `git -C /repo commit` is silently dropped by the
   handler — reporter flagged this as the secondary finding.

Verified locally on macOS Python 3.13:

  - hooks.json valid JSON, 5 `if` clauses each parses to a single
    `{toolName: "Bash", ruleContent: "<command>:*"}` pair.
  - py_compile security_reminder_hook.py clean.
  - 9-case regex sanity: all 4 commit forms match (bare, -C path,
    -c k=v, gt create/modify); 3 non-commit forms reject (status,
    gt submit, gt log). Pre-fix would reject -C path form.
  - 7 new tests in test_2089_if_clause_validity.py + 2 updated tests
    in test_gt_graphite_workflow.py:
      * 12 sanity tests for a Python parser mirroring harness's BA(H)
        — pinned so a future refactor can't silently start accepting
        the broken form.
      * 2 hooks.json validity: every `if` clause parses as a single
        valid rule; at least one if-gated hook exists.
      * 1 post-fix structure: separate entries cover git AND gt.
      * 2 updated gt-coverage: SOME clause covers git, SOME clause
        covers gt (no longer requires both in the same |-joined
        clause, which was the broken shape).

    TDD-verified the test catches the bug: temporarily restored
    main's broken |-joined hooks.json, ran the new test, saw
    `test_every_if_clause_is_single_valid_rule` fail with a clear
    error explaining #2089's cause. Restored fix, test passes.

  - Full suite: 336/353 pass (17 unrelated failures from open PRs
    #2078 / #2086 not in this branch).

NOT verified end-to-end with a real CC instance triggering the hooks
on a git or gt commit. The static-shape tests catch the regression
class and the regex sanity tests pin the `git -C` tolerance, but
the asyncRewake feedback loop needs runtime verification.

Closes #2089. Restores the closes for #2048 that PR #2076 attempted.

security-guidance: pass core.quotePath=false to diff feeders (#2082)
2026-05-29 08:11:25 -07:00
Mohamed Hegazy
38b298d5b2
security-guidance: pass core.quotePath=false to diff feeders (#2082)
Fixes anthropics/claude-plugins-official#2082 — diff feeders use git's
default quotePath setting, which C-quotes any path with a non-ASCII
byte. The downstream parsers in gitutil.parse_diff_into_files /
gitutil.extract_file_paths_from_diff match the diff header with
`re.match(r'^a/(.+?) b/(.+)$', ...)`, which only sees the raw
`a/path b/path` form. The C-quoted `"a/\303\201vila/..."` form
slips past the regex, the `continue` fires, and the file is silently
dropped from review.

Effect: a vulnerable file like `Ávila/payment.py` with
`os.system('curl ' + user_input)` never reaches the LLM reviewer.
False negative in exactly the direction the plugin exists to catch.

Sibling of #2056 / #2075: those fixed the UTF-8 decode of the
subprocess output (text=True crashed the reader thread on Windows
cp1252). This one fixes the diff-feeder commands themselves — the
name-only helpers (_git_name_only, _git_status_porcelain) already
pass core.quotePath=false for this exact reason; the diff-text
feeders were the holdouts.

Fix: add `-c core.quotePath=false` to 4 git invocations:

  - gitutil._git_diff_range            (push-sweep feed)
  - gitutil.get_git_diff                (Stop-hook feed)
  - security_reminder_hook commit-review `git diff` (amend delta)
  - security_reminder_hook commit-review `git show`  (post-amend)

With the flag, git emits raw UTF-8 in the diff header
(`a/Ávila/payment.py`), the regex matches, and both files (the
non-ASCII vulnerable one + any ASCII control file) flow through to
review correctly.

Verified locally on macOS Python 3.13:

  - py_compile clean on both files.
  - Existing 45 smoke + extensibility tests still pass.
  - 8 new tests in test_diff_parser_non_ascii.py (added to internal
    test suite at sg-staging/tests/, not in this PR):

      * 2 static-shape: gitutil._git_diff_range and get_git_diff both
        contain `core.quotePath=false` in their source.
      * 2 commit-review static: every subprocess.run in
        handle_commit_review_posttooluse that mentions `"diff"` or
        `"show"` also passes the flag. Catches the regression
        class where a new diff/show call site is added without
        plumbing the flag through.
      * 4 end-to-end with a real git repo containing a
        `Ávila/payment.py` baseline-and-edit:
          - WITHOUT flag: header is C-quoted, both parsers drop the
            non-ASCII file (demonstrates the bug).
          - WITH flag: header is raw UTF-8, both parsers see the file.
          - parse_diff_into_files (the other parse path) also keeps
            the file with the flag.
          - get_git_diff end-to-end produces unquoted output whose
            file list includes the non-ASCII path.

  - 53/53 pass total (45 existing + 8 new) in 3.41s.

NOT verified end-to-end with a real CC commit-review fire on a
non-ASCII path. The static-shape tests catch the regression and the
end-to-end git-repo tests pin parser behavior, but the actual
LLM-review-with-vuln-found path requires runtime verification against
an Anthropic-API-credentialed CC session.

security-guidance: respect CLAUDE_CONFIG_DIR for plugin state files (#1868)
Fixes #1868 — when CLAUDE_CONFIG_DIR is set to a non-default location
(e.g. ~/.config/claude for XDG compliance, or a multi-tenant install
path), the plugin still wrote state files to the hardcoded ~/.claude/
path, leaving stale state and breaking CLAUDE_CONFIG_DIR's purpose.

Resolution precedence (highest first):
  1. SECURITY_WARNINGS_STATE_DIR  — plugin-specific override (existing)
  2. CLAUDE_CONFIG_DIR/security    — CC's config-dir env (new — #1868)
  3. ~/.claude/security            — default fallback (unchanged)

Empty-string env vars (e.g. CLAUDE_CONFIG_DIR= in a misconfigured
shell) are treated as not-set so the empty path doesn't collide with
os.path.join and silently write to /security at the filesystem root.

Implementation: a single state_dir() helper in _base.py is the source
of truth for resolution. All five modules that previously had inline
SECURITY_WARNINGS_STATE_DIR / ~/.claude/security resolutions
(_base.py, session_state.py, ensure_agent_sdk.py, llm.py, and one
site in security_reminder_hook.py) now call state_dir() instead.
Re-implementing the precedence inline risks drift — one module gets
a future fix, others don't.

The helper is called per-invocation rather than cached at import time
so test monkeypatches of the env vars take effect, and so a long-
running test or future shared-process scenario can change the env
between calls and have the next call observe the new value. The
per-call cost is negligible compared to the subprocess-spawn cost
the hooks pay every fire in production.

Three hardcoded ~/.claude/security strings remain but are NOT
functional resolutions:
  - _base.py:39: the fallback BRANCH inside state_dir() itself
  - ensure_agent_sdk.py:6, :11: docstring text describing default
                                location for users

Verified locally on macOS Python 3.13:

  - py_compile clean on all 5 modified files.
  - Existing 45 smoke + extensibility tests still pass.
  - 14 new tests in test_claude_config_dir.py (added to internal test
    suite at sg-staging/tests/, not in this PR):

      * 7 resolution-semantics: default fallback, CLAUDE_CONFIG_DIR
        override, SECURITY_WARNINGS_STATE_DIR beats both, tilde
        expansion, empty-string handling (CLAUDE_CONFIG_DIR= must
        fall back, NOT join to /security).
      * 4 static-shape: each of session_state / ensure_agent_sdk /
        llm / security_reminder_hook either imports state_dir from
        _base OR has zero resolution patterns. Catches the
        regression where someone adds a new state-file writer and
        re-implements resolution inline, missing the
        CLAUDE_CONFIG_DIR branch.
      * 3 end-to-end: with CLAUDE_CONFIG_DIR set, get_state_file /
        get_lock_file return paths under <CLAUDE_CONFIG_DIR>/security/;
        save_state round-trip writes a file to the redirected path
        and re-reads the same contents.

  - 59/59 pass total (45 existing + 14 new) in 2.54s.

NOT verified end-to-end with a real CC instance setting
CLAUDE_CONFIG_DIR. The shape tests catch the regression class
(hardcoded ~/.claude/), and the end-to-end test pins the behavior
that user state files actually land at the redirected path.

Closes #1868.

37ffc76005
security-guidance: emit findings via hookSpecificOutput.additionalContext (#1358 #1375 #1783)
Fixes #1358, #1375, and #1783 — three related complaints about the
hook output protocol used at the three asyncRewake exit-2 sites
(handle_commit_review_posttooluse, handle_push_sweep_posttooluse,
handle_stop_hook).

The old shape at each site was:

  emit_metrics({...})                              # JSON to stdout (metrics)
  sys.stderr.write(banner + guidance + suffix)     # plain text to stderr
  sys.exit(2)                                      # asyncRewake trigger

That triggered three reported problems:

  #1375: CC's hook system parsing stdout for a SyncHookJSONOutput sees
         only the bare metrics dict — no findings reason — and on older
         CC versions surfaces a 'json output validation failed' error
         because stderr's plain text isn't valid JSON.
  #1783: CC's UI shows 'Permission to use Edit has been denied' with no
         permissionDecisionReason — the stderr text is invisible to that
         UI surface; CC only renders fields it can find in the JSON.
  #1358: Reporters experienced the exit(2) as 'gating' behavior rather
         than 'warning' behavior. The pattern-warning path in main()
         was migrated to exit(0) + hookSpecificOutput.additionalContext
         long ago; these three asyncRewake sites were never updated.

Fix: extend emit_metrics() to accept additional_context, system_message,
and hook_event_name kwargs, and emit them in the same SyncHookJSONOutput
line as the metrics. CC's parser stops scanning stdout after the first
{-prefixed line, so the findings must ride in that same line — calling
emit_metrics twice or adding a second print(json.dumps(...)) would
silently drop the second emission.

At each of the three call sites: route the guidance text that used to
go to stderr through additional_context instead. The stderr.write is
dropped — additionalContext carries the same text to the model via the
JSON channel, and the legacy stderr surface is what triggered #1375's
JSON validation error on older CC clients.

exit(2) is preserved at all three sites. That's the documented mechanism
for triggering the asyncRewake 'force fix' feedback loop (per the
inline comment at the stop-hook site); switching to exit(0) without
verifying CC's protocol-version support risks dropping the rewake
entirely and silently losing all the findings the hook just computed.

For push-sweep specifically: emit_metrics had to move from an
unconditional pre-emission (line ~1680) to two conditional sites (one
in the no-vulns branch with exit(0), one in the with-vulns branch with
exit(2)) because the with-vulns branch needs to attach additional_context
and CC reads only the first JSON line — a second emit would be ignored.
Behavior is preserved: every push-sweep fire emits exactly one metrics
line, just at a slightly later point in the function body.

Verified locally on macOS Python 3.13:

  - py_compile clean.
  - Existing 45 smoke + extensibility tests still pass.
  - 21 new tests in test_hook_output_protocol.py (added to internal
    test suite at sg-staging/tests/, not in this PR):

      * 6 backward-compat: emit_metrics with metrics only, with
        rewake_summary, etc. — verifies the legacy callers still
        produce the same output shape.
      * 5 additional_context shape: lands in hookSpecificOutput,
        round-trips the value, default hook_event_name is sensible,
        empty/None doesn't pollute the JSON with an empty hSO block.
      * 3 system_message shape: lands in systemMessage, empty/None
        suppressed, round-trips.
      * 1 combined: metrics + rewake_summary + additional_context +
        system_message + hook_event_name all merge into one JSON line.
      * 6 round-trip safety: emoji, quotes, backslashes, newlines,
        Unicode (山田太郎 + 🎉), tabs, null bytes — all survive the
        json.dumps cycle.
      * 6 static-shape: each of the three asyncRewake handlers
        (commit_review, push_sweep, stop_hook) is checked to confirm
        it passes additional_context to emit_metrics and no longer
        writes the PROVENANCE_BANNER guidance to stderr. Catches the
        regression class where a new exit(2) site forgets to plumb
        guidance through the JSON channel.

  - 66/66 pass total (45 existing + 21 new) in 2.57s.

NOT verified end-to-end with a real CC instance triggering all three
hooks. The static-shape tests + the JSON round-trip tests should catch
any regression in the emit_metrics output, but the actual interaction
with CC's asyncRewake / rewakeMessage flow (especially: does
hookSpecificOutput.additionalContext successfully appear in the
rewakeMessage that CC sends to the model?) needs runtime verification
against a CC version that supports the modern protocol.

The reporter for #1375 specifically called out that CC's older
versions surfaced 'json output validation failed' on the old stderr-
only output; this fix changes the stdout shape to valid JSON with the
findings included, which should resolve that error class.

security-guidance: detect Graphite (gt) commands as commit/push events (#2048)
Fixes anthropics/claude-plugins-official#2048 — teams using Graphite
for stacked PRs (`gt create` / `gt modify` / `gt submit`) never get
the commit/push agentic review because the hook matcher only catches
literal `git commit` / `git push` Bash calls. gt shells out to git
as a subprocess, but the hook fires on Claude's top-level tool call,
which is `gt create` — not the `git commit` invocation inside the
gt subprocess that Claude Code never observes.

Per-edit pattern checks and end-of-turn Stop review still fire (those
don't depend on detecting the commit command), so the silent-coverage-
gap is bounded to the deepest review layer for Graphite users. Still:
that's exactly the layer designed to catch IDOR / auth-bypass /
cross-file SSRF, so the gap matters.

Semantic mapping (per the reporter):

  gt create  -> commit            (like `git commit`)
  gt modify  -> commit + amend    (like `git commit --amend`)
  gt submit  -> push              (like `git push`)

Changes:

1. hooks/hooks.json: extend two PostToolUse `if` matchers.

   "Bash(git commit:*)"
     -> "Bash(git commit:*)|Bash(gt create:*)|Bash(gt modify:*)"
   "Bash(git push:*)"
     -> "Bash(git push:*)|Bash(gt submit:*)"

   Without this, the hook subprocess never spawns for gt invocations
   and the Python regex changes below are dead code.

2. hooks/security_reminder_hook.py: extend three regexes that classify
   the bash command line.

   _GIT_COMMIT_RE: now also matches `gt create` and `gt modify`.
     Used at 4 sites (handler gate, multi-commit count, prompt
     detection, event classification). Compound commands like
     `gt create -am a && gt submit` now correctly trigger both the
     commit and push paths.

   _GIT_AMEND_RE: now also matches `gt modify` (semantically an
     amend). The amend code path uses reflog to find the pre-amend
     SHA and diff against THAT instead of HEAD~1 — same code path
     now applies to `gt modify`.

   _GIT_PUSH_RE: now also matches `gt submit`. Tolerates the same
     `git -C path` / `git -c k=v` global options as before for the
     git form; gt has its own flag layer that doesn't conflict.

Verified locally on macOS Python 3.13:

  - JSON valid (hooks.json roundtrips).
  - Existing 45 smoke + extensibility tests still pass.
  - 76 new tests in test_gt_graphite_workflow.py (added to internal
    test suite this PR doesn't ship — kept in sg-staging tests/ until
    we have a story for shipping plugin tests publicly):

      * 16 parametrized commit-match: native git commit variants +
        all gt create / gt modify variants from the reporter's repro.
      * 11 parametrized commit-reject: gt submit, gt log, gtoolkit
        (word-boundary), agt create, etc.
      * 9 parametrized amend-match: git commit --amend variants +
        gt modify variants + chained git+gt.
      * 7 parametrized amend-reject: regular git commit, gt create,
        gt submit, echo'd substring noise.
      * 11 parametrized push-match: git push variants + gt submit
        variants + chained.
      * 12 parametrized push-reject: git commit, gt log, gt fetch,
        gt down, gt restack, gh pr create, agt submit.
      * 3 compound-command class tests: git+gt mixtures trigger both
        paths; gt modify chained with gt submit triggers
        amend + push.
      * 3 commit-invocation-count tests: gt commands contribute to
        the multi-commit-detection findall count.
      * 2 hooks.json static config tests: read the JSON, verify the
        commit and push `if` clauses include the gt cases. Catches
        the easy regression where someone updates the Python regex
        but forgets to widen the matcher.

  - 121/121 pass total (45 existing + 76 new) in 2.50s.

NOT verified end-to-end with a real `gt` install. Reporter has the
deterministic Graphite workflow and offered to retest. The regex +
matcher widening is a clean superset — current git-only matching still
works (verified by the 45-test smoke suite that uses `git commit` /
`git push` exclusively), and the new gt cases are pure additions.

Not in this PR:

  - `gt prev` / `gt next` / `gt up` / `gt down` etc. — pure
    navigation, no commit / push side effect.
  - `gt restack` — could in principle rewrite commits (so the
    plugin's reviewed-shas cache becomes stale), but it doesn't
    create reviewable new content. Out of scope.
  - `gh pr create` — already explicitly NOT a separate matcher per
    the existing comment in _GIT_PUSH_RE (gh invokes git push as a
    child process; the bash hook only sees the top-level
    `gh pr create`). Same architectural issue as gt but with a
    different cost/benefit per the existing comment.

security-guidance: lenient UTF-8 decode in 6 git-subprocess helpers (#2056)
Fixes anthropics/claude-plugins-official#2056 — on Windows, when the
worktree contains an untracked file whose name has a character undefined
in cp1252 (accented capitals like Á Í Ï Ð Ý, most CJK, emoji), the
UserPromptSubmit hook crashes:

  Exception in thread Thread-5 (_readerthread):
    UnicodeDecodeError: 'charmap' codec can't decode byte 0x81
  Traceback (most recent call last):
    File diffstate.py, line 338, in _list_untracked
      for p in r.stdout.split('\\0'):
  AttributeError: 'NoneType' object has no attribute 'split'

Non-blocking (UPS failures still let the prompt through) but the
baseline-untracked snapshot is silently lost, so the Stop-hook review
mis-handles pre-existing untracked files.

Root cause (reporter's diagnosis, verified):

1. core.quotePath=false makes git emit raw UTF-8 for non-ASCII filenames.
2. subprocess.run(..., text=True) decodes via
   locale.getpreferredencoding(False) in strict mode — on Windows that
   is cp1252, in which 0x81 / 0x8D / 0x8F / 0x90 / 0x9D are undefined.
   Those bytes appear in the UTF-8 encodings of Á (C3 81), Í (C3 8D),
   Ï (C3 8F), Ð (C3 90), Ý (C3 9D), and a large fraction of CJK / emoji
   codepoints.
3. The decode runs in the subprocess reader thread. The thread raises
   UnicodeDecodeError, threading prints 'Exception in thread Thread-N',
   subprocess.run returns with stdout=None. The handler then does
   None.split('\\0') -> AttributeError, which is NOT in the narrow
   except (TimeoutExpired, FileNotFoundError, OSError) tuple, so it
   escapes the helper, propagates out of UserPromptSubmit's
   ThreadPoolExecutor.result(), and exits the hook non-zero.

This is internally inconsistent: gitutil._git_diff_range,
security_reminder_hook._reflog_amend_lookup (line ~540), and the commit
diff loop (line ~1115) already do bytes + decode utf-8/replace, with
comments explicitly noting that text=True would crash. The fix below
extends that established pattern to the helpers that were holdouts.

Affected helpers (6 total):

  - diffstate._list_untracked            <- reporter, hot path, CRITICAL
  - diffstate.capture_git_baseline       <- reporter, latent
  - diffstate.get_baseline_file_content  <- audit, file content read, HIGH
  - gitutil._git_name_only                <- reporter, latent
  - gitutil._git_status_porcelain         <- reporter, latent
  - gitutil._git_reflog_recent_commits    <- audit, embeds %gs commit msg, HIGH

For each one:

  - Drop text=True from subprocess.run.
  - Decode r.stdout / r.stderr as .decode('utf-8', errors='replace').
  - Add ValueError to the except tuple as defense against any future
    strict-decode regression (UnicodeDecodeError is a ValueError
    subclass; including it explicitly degrades the helper to its
    empty/None return instead of escaping out of the hook).

Verified locally on macOS Python 3.13:

  - py_compile clean on both files.
  - 45 existing smoke + extensibility tests still pass.
  - 21 new internal tests (not in this PR — added to the team's local
    test suite at staging/tests/test_unicode_decode.py):
      * 18 static-shape parametrized: each of the 6 fixed helpers has
        no text=True in its subprocess calls, contains errors='replace',
        and lists ValueError in its except.
      * Deterministic end-to-end: create real git repo + Ávila_report.txt
        untracked, call _list_untracked, verify it returns
        {'Ávila_report.txt': <mtime>} without crashing.
      * Deterministic end-to-end: same for capture_git_baseline (verifies
        the latent stderr-warning case stays valid).
      * Deterministic end-to-end: get_baseline_file_content on a file
        whose content has 山田太郎 + 🎉; verify the bytes round-trip
        through the decode.
  - 66/66 tests pass total (45 existing + 21 new).

NOT verified end-to-end on Windows — would need actual cp1252 strict
decode to fire. Reporter has the deterministic repro and will
re-verify on their Win11 / Python 3.14.x setup before merge.

Not in this PR (defense-in-depth, lower risk):

  - 3 git rev-parse calls returning path output (gitutil._find_git_index,
    _git_toplevel, _git_dir) could fail on Windows if cwd is in a
    non-ASCII install directory. Same fix shape but unreported and
    much lower probability — worth a separate follow-up if anyone
    actually hits it.

security-guidance: gate XSS pattern rules to JS-family files
Closes #410, #2037, #2045, #1640, #1280, #1329, #1341, #255,
anthropics/claude-code#46720 (partial closes on overlap with other rules).

The plugin's substring-only XSS / browser-DOM rules
(new_function_injection, react_dangerously_set_html, document_write_xss,
innerHTML_xss, outerHTML_xss, insertAdjacentHTML_xss) fired on any file
containing the trigger substring — including:

  * Markdown documentation explaining XSS sinks
  * Blog posts / READMEs that name browser APIs
  * Python tutorials referencing dangerouslySetInnerHTML
  * Plugin skill files with example HTML strings
  * .yaml / .json configs that happen to contain the literal string
  * .gitignore / Dockerfile / Makefile

These constructs have no meaning outside JS/TS source. Add a
path_filter: lambda p: p.endswith(_JS_EXTS) to each so they fire only
on .js, .jsx, .ts, .tsx, .mjs, .cjs, .mts, .cts, .vue, .svelte.

Cross-checked against the existing _JS_EXTS-gated rules
(regex_exec_substring, child_process_exec, exec_substring) — same
pattern, same constant, same intent. Uses the module-level _JS_EXTS
tuple so future extension changes propagate to all 6 rules atomically.

Verified locally on macOS Python 3.13:
  - py_compile clean.
  - 45-test existing smoke + extensibility suite still passes.
  - 151 new parametrized tests in test_xss_gate.py (added to internal
    test suite this PR doesn't ship): each gated rule x every
    JS-family extension accepts, x every non-JS path (.md / .py /
    .yaml / .json / .txt / .html / Dockerfile / Makefile / .gitignore
    / .sh / .go / .rs / .rb) rejects. 196 tests pass total.

Doesn't address everything in the false-positive cluster — issues that
require Python-rule gating (#1114 .env.schema exec), tighter substring
scoping (#660 pickle in usernames), or hook-protocol changes (#1358
exit-2 vs warning, #1375 plain-text-vs-JSON output) need separate PRs.
This PR covers the JS-substring subset cleanly.

security-guidance: enable LLM review on default macOS Python 3.9
Fixes anthropics/claude-plugins-official#2071 — on macOS where the
default `python3` is Apple's Command Line Tools Python 3.9.6, the
plugin's agentic commit reviewer silently does not run, even when the
user has a newer Python installed.

Three compounding factors in the bug:

1. `sg-python.sh` only checks the major version (`3`), so it always
   picks 3.9 even when 3.10+ is on PATH.
2. `claude_agent_sdk` requires Python >=3.10 — pip install on 3.9
   returns "No matching distribution" -> bootstrap returns BUILD_FAILED.
3. Even with a hand-built 3.12 venv, `llm.py` imports the SDK
   in-process into the hook's interpreter (still 3.9), which raises
   SyntaxError. The existing venv-probe in `ensure_agent_sdk.py` uses
   the venv's own Python (3.12) so it reports NOOP_VENV (healthy) while
   the consumer fails — misleading telemetry on top of silent feature
   degradation.

Per BQ telemetry, 14,073 external macOS users hit
sdk_bootstrap=BUILD_FAILED in the past 4 days (the default-macOS
cohort), out of ~86K total external installed users. Combined with
~20K other users in similar broken-bootstrap states (Windows pre-#2055,
Linux <3.10), about half the installed base has a silently-broken
agentic reviewer.

This PR implements the reporter's items #1, #3, and #4. Item #2
(running the SDK out-of-process) is deferred as a bigger refactor.

Item #1 — hooks/sg-python.sh — prefer >=3.10 binaries via 3-pass probe:

  Pass 1: python3.13 / 3.12 / 3.11 / 3.10 (>=3.10 by name, highest wins)
  Pass 2: bare python3 / python / py -3 (accept only if reported >=3.10)
  Pass 3: bare python3 / python / py -3 (any Python 3, FALLBACK so
          pattern checks still work on macOS-default 3.9 — no regression
          vs today; SDK-dependent paths detect the version mismatch
          inside Python and degrade cleanly via item #4)

Item #4 — ensure_agent_sdk.py — health-check honesty:

Added HOOK_PY_INCOMPATIBLE=6 outcome with short-circuit at top of main():

  if sys.version_info < (3, 10):
      return HOOK_PY_INCOMPATIBLE, "hook_py", f"py_{...}"

Telemetry consequences after rollout: sdk_bootstrap=6 is a new clean
bucket; some users currently miscounted in sdk_bootstrap=3 BUILD_FAILED
(wasted pip cycles) and sdk_bootstrap=1 NOOP_VENV (falsely-healthy)
move to sdk_bootstrap=6. The remaining NOOP_VENV count becomes
trustworthy.

Item #3 — ensure_agent_sdk.py — one-time user-visible notice:

When outcome == HOOK_PY_INCOMPATIBLE and a marker file at
`~/.claude/security/.agentic_unavailable_notice_v<pv>` doesn't exist,
the SessionStart response includes hookSpecificOutput.additionalContext
+ systemMessage explaining the situation. Marker file is plugin-
version-keyed so a future fix (e.g. shipping out-of-process SDK) can
bump pv and re-notify users.

BUILD_FAILED is intentionally excluded from the notice — it covers
transient causes where a permanent banner would mislead.

Verified locally on macOS Python 3.13:
  - py_compile clean on both files.
  - Existing 45-test smoke + extensibility suite: 45/45 PASS in 2.50s.
  - Unit test of simulated 3.9 path: HOOK_PY_INCOMPATIBLE returned with
    correct phase/kind; notice shown on first call, suppressed on
    second, reshown on bumped pv; BUILD_FAILED correctly does NOT
    trigger notice.

NOT verified: actual Python 3.9 behavior end-to-end (would need a 3.9
install). Worth a follow-up smoke test in a 3.9 venv before next
release. The unit test simulating 3.9 covers the logic but not the
runtime invocation through the shim.

recommender: add Convex to database/backend MCP coverage (#1981)
Picked up from sethconvex's PR #1966 (auto-closed by membership gate),
split off from #1980 (Convex plugin entry refresh) so the editorial
addition to claude-automation-recommender gets its own review.

Changes:

- SKILL.md: add `convex` to the package.json dep-detection grep, update
  the Database row in the indicator table to name Convex, and add a
  Convex MCP row to the MCP recommendation table.

- references/mcp-servers.md: new "Convex MCP" section in the Databases
  group (Supabase / Convex / PostgreSQL / Neon / Turso), and a row in
  the Detection Patterns quick reference.

Convex publishes its MCP server via the `convex` npm package
(`npx convex mcp start`), exposing tables, function-spec, data,
run-once-query, logs, env list/set/get. Same row pattern as the
existing database/backend MCP entries.

Address Windows verification: --prefer-binary + pywin32 bootstrap
The first round of this PR removed SKIP_WIN32, fixed venv_py to use
Scripts/python.exe, and added Lib/site-packages to the consumer glob —
all necessary. Windows verification (Win11 ARM64, Py 3.13, Git Bash)
showed two more blockers, both addressed here.

1. Pip dependency resolver picks unbuildable cryptography on ARM64.

   Without --prefer-binary, pip picks a cryptography version with no
   published ARM64 wheel and tries to build it from source. That needs
   Rust/Cargo, almost never present on user machines → BUILD_FAILED
   with err_kind=other:cryptography. A binary wheel exists for an
   adjacent version (cryptography-46.0.3-cp311-abi3-win_arm64.whl);
   --prefer-binary tells pip to pick it. Cross-platform safe (no-op
   where the latest version already has a wheel).

2. pywin32 .pth files aren't processed by sys.path.insert().

   With the venv built, ensure_agent_sdk.py's post-build probe passes
   (it runs from venv_py, where Python's site.py at startup processes
   pywin32.pth and registers win32/, win32/lib/ plus runs
   pywin32_bootstrap.py to set the DLL search dir). But llm.py runs in
   the hook's SYSTEM Python and adds the venv via sys.path.insert(),
   which doesn't trigger site.py at all. Without the bootstrap, the
   SDK's mcp.client.stdio → mcp.os.win32.utilities chain raises
   ModuleNotFoundError: pywintypes and the agentic reviewer falls back
   to single-shot silently — exactly the symptom this PR is trying to
   fix. The probe says NOOP_VENV; the actual consumer fails. Probe and
   consumer use different Pythons.

   Replicate what site.py would do: after inserting site-packages,
   also insert win32/ and win32/lib/, then exec pywin32_bootstrap.py.
   Pulled into a shared helper _inject_agent_sdk_venv_into_syspath()
   so both consumer sites (3P SDK fallback, agentic_review fallback)
   call the same code — Windows handling stays in one place.

Verified on macOS (POSIX path unchanged):
- Helper end-to-end test: POSIX-layout venv detected + fake package
  imports successfully via the injected path
- Windows-layout venv also detected; win32 branch correctly skipped
  via sys.platform check
- Both files pass py_compile

Credit: @mhegazy verified the previous commit on Win11 ARM64 / Py 3.13
/ Git Bash, surfaced both issues end-to-end, and provided the exact
fix patterns. This commit applies them with the pywin32 part factored
into a shared helper (vs. inlining at both consumer sites).

Enable agentic commit reviewer on Windows
The agentic reviewer is silently no-op on Windows today. SessionStart
bootstrap (ensure_agent_sdk.py) short-circuits with SKIP_WIN32 because
the consumer glob in llm.py only matches POSIX venv layout
(lib/pythonX.Y/site-packages). On Windows, venvs use Lib/site-packages
(capital L, no pythonX.Y subdir), so even if a venv got built the
glob wouldn't find its contents.

Result: Windows users on default installs (no system-wide
claude_agent_sdk) get layer 1 (pattern warnings) and layer 2 (single-
shot LLM diff review) but not layer 3 — the cross-file agentic review
that catches IDOR, auth-bypass, cross-file SSRF, and other things that
need to read related files. Plugin description claims layer 3 but it
silently doesn't run.

Three changes:

1. llm.py — extend the consumer glob (2 sites: 3P SDK fallback at
   ~L297, agentic_review fallback at ~L1090) to also match the Windows
   Lib/site-packages layout, so a venv built on Windows is actually
   discoverable.

2. ensure_agent_sdk.py — remove the sys.platform == 'win32' early-exit
   so the SessionStart bootstrap builds the venv on Windows too.
   Outcome code 4 (formerly SKIP_WIN32) is retired but not reused so
   pre-fix telemetry rows still decode correctly.

3. ensure_agent_sdk.py — venv_py path now branches on sys.platform:
   Windows venvs put the interpreter at Scripts\python.exe; POSIX
   uses bin/python. Previously assumed POSIX, so even with the glob
   fix, the post-build SDK-importability probe would fail on Windows.

Verified locally on macOS:
- glob test: both layouts now match (POSIX venv detected, simulated
  Windows venv also detected via the new Lib/site-packages branch)
- both files pass py_compile
- POSIX path unchanged (sys.platform != 'win32' so old branch runs)

Not verified on Windows in this commit — needs an actual Windows
runner to confirm the venv build + SDK import + subprocess plumbing
all work end-to-end. The SDK spawns a child claude.exe; Windows
process plumbing has its own quirks (shell semantics, path escaping)
that may surface separately. Worth a controlled rollout (one-week
soak under env-var opt-in before flipping default).

Convert POSIX script paths to Windows form before exec on Git Bash
Fixes #2043. On Git Bash for Windows, Claude Code hands script paths to
the shim in POSIX form (`/c/Users/...`). We exec a Windows `python.exe`
(the `python3` Microsoft Store stub fails the probe), and Windows Python
interprets the leading `/` as the root of the current drive — `/c/...`
becomes `C:\c\Users\...` or `D:\c\Users\...` depending on which
drive the shell happens to be on, fails with ENOENT, and every
Edit/Write/MultiEdit blocks until the session restarts.

Convert absolute path args via `cygpath -w` (a Git Bash builtin) before
exec. Guarded by `command -v cygpath` so macOS/Linux fall straight
through unchanged; `cygpath -w` is idempotent on already-Windows paths
so the rare mixed-form case is safe. Only `/*` paths are converted —
Windows-form paths reaching the shim are already openable by python.exe.

Verified locally:
- cygpath absent on macOS → guard skips → POSIX behavior unchanged
- end-to-end shim invocation with a POSIX path on macOS exits 0
- stubbed cygpath -w on /c/Users/test/hook.py produces C:\Users\test\hook.py

Aligns the compose service name, local config filename, and all

fix: quote \${CLAUDE_PLUGIN_ROOT} in hookify and security-guidance hook commands
Paths containing spaces (common on Windows, e.g. C:\Users\Some User\...)
cause shell word-splitting when CLAUDE_PLUGIN_ROOT is unquoted, resulting
in hooks erroring with "No such file or directory" on every tool call.

Wraps the path in double quotes for all five affected hook commands.
Fixes the pattern reported in issue #57946. Closes the fix surfaced in PR #1921.

code-modernization: fix pipeline gaps, redesign harden, dry-run hardening

code-modernization: harden writes a patch instead of editing legacy; make map/security guidance language-agnostic
- modernize-harden: never edits legacy/ anymore. Writes findings plus a
  reviewed unified diff to analysis/<system>/security_remediation.patch.
  A second security-auditor pass reviews each hunk (RESOLVES / PARTIAL /
  INTRODUCES-RISK) before presenting. The user reviews and applies the
  patch deliberately, then re-runs to verify. This makes every command
  consistent with the recommended deny Edit(legacy/**) workspace setting,
  so the README's exception note is gone.
- modernize-map: restructure the parse-target list around three stack-
  agnostic principles (dispatcher targets are variables; code-storage
  joins live in config; entry points live in deployment descriptors), with
  COBOL/Java/web/CLI examples on equal footing rather than COBOL-dominant.
  Same protections against false dead-code findings, less stack-specific.
- security-auditor agent: rephrase coverage items in stack-neutral terms
  (record layouts/temp datasets, resource ACLs, deployment scripts/job
  definitions, batch input records) so the checklist reads naturally for
  COBOL, Java EE, .NET, and web targets alike.
- README: drop the harden exception note; describe the patch workflow.

Harden code-modernization plugin from a real CardDemo dry run
Fixes found by running the discovery workflow against the AWS CardDemo
mainframe sample (~50 KLOC of COBOL/CICS/JCL/BMS/VSAM):

- modernize-assess: add scc -> cloc -> find/wc fallback chain with the
  COCOMO-II formula so Step 1 works when scc isn't installed; same for
  portfolio-mode cloc/lizard. Drop the reference to a specific
  agent-spawning tool name (just "in parallel"). Sharpen the structural-
  map subagent prompt: 5-12 domains, subgraph clustering, ~40-edge cap,
  repo-relative paths, dangling-reference check.
- modernize-map: expand the parse-target list with the things a
  literal-minded reader would miss on a real mainframe codebase — CICS
  CSD DEFINE TRANSACTION/FILE for entry points and online file I/O,
  EXEC CICS file ops, SELECT...ASSIGN TO joined with JCL DD,
  EXEC SQL table refs (not JCL DD), SEND/RECEIVE MAP, dynamic
  data-name XCTL resolution, COBOL fixed-format column slicing. Without
  these the dead-code list is wrong (most CICS programs look unreachable).
  Also write a machine-readable topology.json alongside the summary.
- modernize-extract-rules: add a Priority (P0/P1/P2) field with a
  heuristic, and an optional Suspected-defect field. modernize-brief
  reads P0 rules to build the behavior contract, but the Rule Card had
  no priority slot — the chain was broken.
- modernize-brief: read the new P0 tags; flag low-confidence P0 rules as
  SME blockers.
- modernize-reimagine: drop "for the demo" wording.
- security-auditor agent: add mainframe/COBOL coverage items (RACF,
  JCL/PROC creds, BMS field validation, DB2 dynamic SQL, copybook PII)
  and mark web-only items as such so it adapts to the target stack.
- README: add Optional Tooling section and a symlink example for the
  expected layout.

Fix code-modernization plugin: align README with commands, fix pipeline gaps
- modernize-brief: read TOPOLOGY.html (what modernize-map actually
  produces) instead of nonexistent TOPOLOGY.md, and tell the user which
  command produces each missing input.
- README: rewrite the Commands section to match actual command behavior —
  correct output filenames, ordering (brief is the synthesis/approval gate
  after discovery, not the first step), agent attributions, and required
  args. Add a workspace-layout note and an explicit callout that
  modernize-harden edits legacy/, which conflicts with the recommended
  deny rule. Reconcile the Overview and Typical Workflow sequences.
- modernize-assess: generalize the production-runtime overlay step so it
  no longer assumes a specific MCP server/tool; mark it optional. Fix
  app/jcl/ -> legacy/$1/jcl/ for layout consistency.
- modernize-map: make TOPOLOGY.html self-contained (load Mermaid from a
  CDN) so it renders in any browser; drop assumptions about an external
  artifact renderer. Generalize the telemetry annotation note.
- business-rules-extractor agent: fix command cross-reference to the
  actual command name.
- plugin.json: include the brief step in the workflow description.

cwc-makers: curl+tar fallback when git is missing (#1731)
/maker-setup now falls back to GitHub's tarball endpoint when git isn't
on PATH, instead of detouring through a package-manager git install.
curl and tar ship with macOS, Linux, and Windows 10 1803+ out of the
box, so this is zero-install on every target platform — and a CwC
attendee just needs the files once to flash a device, not git history.

- maker-setup.md: git-clone fast path, curl|tar (Unix) / curl+tar+
  Rename-Item (PowerShell) fallback, normalizes the -main suffix
- m5-onboard/SKILL.md: drop git from required deps + per-OS git
  bootstrap block; keep Python bootstrap
- README: git now listed as optional

* Add cwc-makers plugin: /keep-thinking Cardputer onboarding

Packages the Code-with-Claude Makers (claude.com/cwc-makers) Cardputer
experience as a one-command flow for event attendees:

- commands/keep-thinking.md: user entry point — clones
  moremas/build-with-claude and runs the m5-onboard provisioning flow
- skills/m5-onboard/SKILL.md: vendored from upstream onboard/SKILL.md;
  Installation section replaced with clone-location note; explicit
  'relay physical button steps to user' directive added
- skills/cardputer-buddy/SKILL.md: post-onboarding app iteration

All three are user-invocable; /keep-thinking is the intended entry
point. Skill content is Apache-2.0 from the upstream repo.

Replace transcript-style agent examples with prose trigger descriptions
Several agent files used <example> blocks containing user: "..." /
assistant: "..." turn markers, embedded as \n-escaped strings inside
the YAML frontmatter description: field. Replace those with flat prose
trigger descriptions in description: and a 'When to invoke' section
in the agent body containing prose-bullet scenarios.

Affected files:
- 5 agent definitions:
  - plugins/hookify/agents/conversation-analyzer.md
  - plugins/pr-review-toolkit/agents/code-reviewer.md
  - plugins/pr-review-toolkit/agents/pr-test-analyzer.md
  - plugins/pr-review-toolkit/agents/type-design-analyzer.md
  - plugins/pr-review-toolkit/agents/comment-analyzer.md
- 5 agent-development skill files updated to teach the new format:
  - plugins/plugin-dev/skills/agent-development/SKILL.md
  - .../references/triggering-examples.md
  - .../references/agent-creation-system-prompt.md
  - .../examples/complete-agent-examples.md
  - .../examples/agent-creation-prompt.md

Routing is unaffected: each description: still names the trigger
surface in plain English.

skill-creator: sync from anthropics/skills (drop ANTHROPIC_API_KEY requirement) (#1523)
Ports anthropics/skills#547 (b0cbd3d) so this repo matches the upstream
skills repo.

improve_description.py and run_loop.py now shell out to `claude -p` instead
of using the Anthropic SDK directly, so the description optimizer uses the
session's existing Claude Code auth and no longer requires a separate
ANTHROPIC_API_KEY. SKILL.md drops the stale extended-thinking reference and
adds guidance for updating an existing skill.

Several enterprise customers sync exclusively from this repo (not
anthropics/skills, whose README disclaims production use), so they have been
stuck on the old SDK-based path.
