A Claude Code plugin that intercepts GitHub URL fetches and redirects Claude to use the authenticated gh CLI instead.
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
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

- 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.
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.
- GitHub CLI (
gh) must be installed and authenticated (gh auth login) - If
ghis not installed, the hooks pass through without disruption
