Pull request CI in this repository is slow, and it is hard to tell whether the bottleneck is runner queue contention, long test jobs, or workflow misconfiguration. This Skill collects per-job and per-step timing data from GitHub Actions, separates queue time from execution time, and turns the findings into a ranked report plus concrete, low-risk fixes.
Ask the assistant to run the CI performance report for this repository, for example: run the ci-perf analysis and tell me where our PR wall-clock time is going.

Run the bundled collect_ci_data.py script with an authenticated gh CLI to snapshot recent PR workflow runs. It records per-job execution and wait times, per-step timings, and pytest durations, which the analysis phase splits into queue time versus execution time.
Add --durations=50 to the pytest invocation in the workflow, then the collector mines those duration blocks from Build test-job logs. Aggregate across runs by median per test, including setup and teardown phases where fixture-heavy offenders hide.
The dominant cause is often runner queue contention rather than execution time, especially when many jobs fan out per PR. Check wait-from-run-start per job, subtracting predecessor completion for dependent jobs, and inspect p90 step variance such as full-history checkouts.
In interactive mode it always shows the diff and PR body and waits for approval before pushing. In scheduled unattended mode it may open one PR with up to two safe fixes, but structural changes are only filed as issues for maintainer decision.
It never proposes trimming the Python version matrix and never opens PRs for structural changes like renaming required checks, altering job topology, or changing retry policy. Those are ranked in the report and filed as issues when ripe.
