Project instructions for gh-watch, a Go command-line tool that watches GitHub pull requests, commits, branches, and tags for changes.

In plain words
What is it for?
Use them when modifying gh-watch or working on its GitHub queries, state comparisons, event reporting, polling, or tests.
Why use it?
They give a coding agent the repository's architecture, design decisions, development practices, and testing context before it edits the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gh-watch CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

gh-watch

A gh CLI extension that watches GitHub resources for state changes. See README.md for usage, flags, event types, and output format.

Architecture

  • main.go — CLI entry point (cobra). Root command + pr, commit, branch, and tag subcommands.
  • internal/checks/ — Shared CheckRun type, CI summary helpers, and StatusContext mappers used by both PR and commit.
  • internal/pr/ — PR state snapshot types and GraphQL fetcher (via go-gh SDK).
  • internal/commit/ — Commit CI state snapshot types and GraphQL fetcher.
  • internal/branch/ — Branch head-commit snapshot types and GraphQL fetcher.
  • internal/tag/ — Tag list snapshot types and fetcher. Lists tags via GraphQL; for --contains, resolves ancestry via the REST compare API (api.DefaultRESTClient) — the only REST usage in the repo — memoized per tag SHA.
  • internal/events/ — Event types and diffing logic. ci.go has shared CI diff logic; diff.go adds PR-specific events (reviews, comments, merge conflicts); commit_diff.go handles commit initial state; branch_diff.go emits new-commit; tag_diff.go emits tag-created.
  • internal/poller/ — Generic poller using Go generics (Config[S any]). Pluggable strategy interface (currently FixedStrategy). Wraps Fetch in cenkalti/backoff/v5 to retry transient errors (default 30min budget per poll, so a watch outlives a GitHub incident).
  • internal/retry/ — Classifies API errors as transient (IsTransient): GitHub 5xx/429, secondary rate limits (403 + Retry-After, surfaced via RetryAfter), GraphQL INTERNAL errors returned with HTTP 200, network errors, timeouts, and malformed bodies.
  • internal/output/ — JSON to stdout.
  • plugin/ — Claude Code plugin: provides skills for monitoring PRs, commits, branches, and tags.

Key design decisions

  • Named gh-watch (not gh-watch-pr) to support future subcommands like gh watch commit, gh watch branch.
  • Poller uses generics so it's reusable for future watch targets beyond PRs.
  • Only aggregate CI events are emitted (ci-passed, ci-failed) — individual check transitions are noise.
  • Dependencies: go-gh/v2 (GitHub API/auth), cobra (CLI), cenkalti/backoff/v5 (retry). Auth is inherited from gh automatically.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
