- 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.
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.
