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.
