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.

Claude Code Plugins Directory
A curated directory of high-quality plugins for Claude Code.
⚠️ Important: Make sure you trust a plugin before installing, updating, or using it. Anthropic does not control what MCP servers, files, or other software are included in plugins and cannot verify that they will work as intended or that they won't change. See each plugin's homepage for more information.
Structure
/plugins- Internal plugins developed and maintained by Anthropic/external_plugins- Third-party plugins from partners and the community
Installation
Plugins can be installed directly from this marketplace via Claude Code's plugin system.
To install, run /plugin install {plugin-name}@claude-plugins-official
or browse for the plugin in /plugin > Discover

Internal Plugins
Internal plugins are developed by Anthropic team members. See /plugins/example-plugin for a reference implementation.
External Plugins
Third-party partners can submit plugins for inclusion in the marketplace. External plugins must meet quality and security standards for approval. To submit a new plugin, use the plugin directory submission form.
Plugin Structure
Each plugin follows a standard structure:
plugin-name/
├── .claude-plugin/
│ └── plugin.json # Plugin metadata (required)
├── .mcp.json # MCP server configuration (optional)
├── commands/ # Slash commands (optional)
├── agents/ # Agent definitions (optional)
├── skills/ # Skill definitions (optional)
└── README.md # Documentation
Skill-bundle plugins
When a plugin's source repository ships skills (SKILL.md files) without a .claude-plugin/plugin.json manifest, the marketplace entry can declare the skills directly using strict: false and an explicit skills array.
{
"name": "example-bundle",
"description": "Brief description of the bundled skills.",
"author": { "name": "Author Name" },
"category": "development",
"source": {
"source": "git-subdir",
"url": "https://github.com/example-org/sdk.git",
"path": "packages/agent-skills",
"ref": "main",
"sha": "<commit sha>"
},
"strict": false,
"skills": [
"./skill-a",
"./skill-b",
"./skill-c"
],
"homepage": "https://github.com/example-org/sdk"
}
Each path in skills is relative to source.path and points at a directory containing a SKILL.md. Paths can reach deeper than a single level — for example, ["./libA/skill-1", "./libB/skill-2"] exposes a curated subset across multiple library subdirectories. Each skill is registered as <plugin-name>:<skill-name> in Claude Code.
For the underlying schema, see Strict mode in the marketplace documentation.
