PR Blocker Summarizer

Turn a JSON export of open pull requests into a blockers-first digest: which PRs are blocked (failing checks, requested changes, or stale), which are ready to merge, and a one-line count an agent can post to standup.

A bundled example skill — small but real, used to demonstrate the creator's validation, pipeline, and eval-rollout machinery.

Activation

Activates on "summarize open PRs", "what's blocking my PRs", "PR standup", "review backlog". Do not activate on general git/GitHub questions unrelated to triaging a set of PRs.

Input

A JSON array of PRs, each with title, state (open), checks (passing/failing), review (approved/changes_requested/pending), and age_days. Missing fields are treated conservatively (counted as not-blocked only when clearly ready).

Run

python3 scripts/run_pipeline.py --input prs.json --output digest.json

Output JSON shape:

{
  "total": 7,
  "blocked": [{"title": "...", "reasons": ["failing checks"]}],
  "ready": ["..."],
  "summary": "7 open · 3 blocked · 2 ready to merge"
}

Gotchas

• `blocked` + `ready` does not equal `total`. A PR is ready only when

checks is explicitly passing and review is explicitly approved. A PR with no blockers but a missing checks field lands in neither list and vanishes from both counts. Never narrate the summary line as if the two numbers account for every PR — say "N blocked, M ready" and leave the remainder unclaimed.

• `state` is read from the input but never filtered on. A closed or merged PR

left in the export is counted in total and classified like any open one. Filter the export before running if it may contain non-open PRs.

• `review: pending` counts as blocked ("awaiting review"). A PR opened five

minutes ago is reported as a blocker. This is intentional for standup triage, but it inflates the blocked count on teams that open PRs early.

• A non-numeric `age_days` silently skips the stale check rather than erroring.

An export with "age_days": "unknown" will never flag anything stale, and the digest gives no sign that the check did not run.

Anti-goals

• Does not call the GitHub API; it works on an exported PR list.
• Does not merge or comment on PRs; it only summarizes.
