* Remove legacy codex compatiblity scripts/shims. Codex supports claude plugins so this shouldn't be necessary. Add a script to test the plugin loadablility in both claude and codex * fix: resolve code review findings for PR #173 Review findings addressed (4 reviewers: pr-review-toolkit agents, Codex gpt-5.3-codex, direct diff review): P2 fixed: - Bump versions for the 5 substantively changed plugins in both plugin.json and marketplace.json (gh-cli 1.5.0 new skill, claude-in-chrome-troubleshooting 1.1.0 skill rename, modern-python 1.5.1 / skill-improver 1.0.3 hooks change, zeroize-audit 0.1.1 MCP config relocation) so clients pick up the changes - README Codex install: replace unpasteable /plugins slash-command block with verified CLI syntax (codex plugin marketplace add) - check_claude_loadability: parse_json_output now fails fast with command context on empty CLI output instead of returning None - check_codex_loadability: surface skipped RPC error messages in timeout failures instead of a bare TimeoutError P3 fixed: - Both checkers: error out when marketplace.json lists no plugins instead of passing vacuously Dismissed: - @latest CLI installs in validate.yml: deliberate; the check validates against the clients users actually run - select.select portability: CI-only script on ubuntu-latest - Divergent mcpServers validation between checkers: intentional; the Codex checker enforces the repo's .mcp.json convention Verified: ruff, prek, validate_plugin_metadata.py, and both loadability checks pass end-to-end (39 plugins, 74 skills, 2 MCP servers load in Claude Code and Codex) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Dan Guido <dan@trailofbits.com> Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
gh-cli
A Claude Code plugin that intercepts GitHub URL fetches and redirects Claude to use the authenticated gh CLI instead.
Problem
Claude Code's WebFetch tool and Bash curl/wget commands don't use the user's GitHub authentication. This means:
- Private repos: Fetches fail with 404 errors
- Rate limits: Unauthenticated requests are limited to 60/hour (vs 5,000/hour authenticated)
- Missing data: Some API responses are incomplete without authentication
Solution
This plugin provides:
- PreToolUse hooks that intercept GitHub URL access via
WebFetchorcurl/wget, and suggest the correctghCLI command - A
ghPATH shim that blocks anti-patterns: API/contents/fetching and non-session-scoped temp directory clones - A SessionEnd hook that automatically cleans up cloned repositories when the session ends
What Gets Intercepted
| Tool | Pattern | Suggestion |
|---|---|---|
WebFetch |
github.com/{owner}/{repo} |
gh repo view owner/repo |
WebFetch |
github.com/.../blob/... |
gh repo clone + Read |
WebFetch |
github.com/.../tree/... |
gh repo clone + Read/Glob/Grep |
WebFetch |
api.github.com/repos/.../pulls |
gh pr list / gh pr view |
WebFetch |
api.github.com/repos/.../issues |
gh issue list / gh issue view |
WebFetch |
api.github.com/... |
gh api <endpoint> |
WebFetch |
raw.githubusercontent.com/... |
gh repo clone + Read |
Bash |
curl https://api.github.com/... |
gh api <endpoint> |
Bash |
curl https://raw.githubusercontent.com/... |
gh repo clone + Read |
Bash |
wget https://github.com/... |
gh release download |
Bash (shim) |
gh api repos/.../contents/... |
gh repo clone + Read |
Bash (shim) |
gh repo clone ... /tmp/... (non-session-scoped) |
Session-scoped clone path |
What Passes Through
- Non-GitHub URLs (any domain that isn't
github.com,api.github.com,raw.githubusercontent.com, orgist.github.com) - GitHub Pages sites (
*.github.io) - Commands already using
gh(except anti-patterns blocked by the shim; see table above) - Git commands (
git clone,git push, etc.) - Search commands that mention GitHub URLs (
grep,rg, etc.)
Note: When hooks deny blob/tree/raw URLs, the denial message explicitly warns against using gh api to fetch and base64-decode file contents as a fallback — clone the repo instead.
Automatic Cleanup
Cloned repositories are stored in session-scoped temp directories ($TMPDIR/gh-clones-<session-id>/). A SessionEnd hook automatically removes them when the session ends, so there's no manual cleanup needed and concurrent sessions don't interfere with each other.
Prerequisites
- GitHub CLI (
gh) must be installed and authenticated (gh auth login) - If
ghis not installed, the hooks pass through without disruption
Installation
