GitHub Actions Rerun Effectiveness Audit

Use this skill to measure how often workflows require reruns and whether reruns are actually recovering failures.

What this skill does

• Reads GitHub Actions run JSON exports
• Tracks rerun episodes using workflow run id + attempt history
• Measures rerun rate, rerun success rate, and extra rerun attempts
• Estimates wasted rerun minutes from attempt durations
• Emits severity (ok, warn, critical) for CI policy gates

Inputs

Optional: - RUN_GLOB (default: artifacts/github-actions/*.json) - TOP_N (default: 20) - OUTPUT_FORMAT (text or json, default: text) - GROUP_BY (workflow or workflow-branch, default: workflow) - FAILURE_CONCLUSIONS (comma-separated, default: failure,cancelled,timed_out,startup_failure,action_required) - SUCCESS_CONCLUSIONS (comma-separated, default: success) - MIN_RUNS (minimum workflow runs required, default: 4) - WARN_RERUN_RATE (0..1, default: 0.2) - CRITICAL_RERUN_RATE (0..1, default: 0.35) - WARN_RERUN_SUCCESS_RATE (0..1, default: 0.5) - CRITICAL_RERUN_SUCCESS_RATE (0..1, default: 0.25) - WARN_WASTED_MINUTES (default: 20) - CRITICAL_WASTED_MINUTES (default: 60) - WORKFLOW_MATCH / WORKFLOW_EXCLUDE (regex, optional) - BRANCH_MATCH / BRANCH_EXCLUDE (regex, optional) - EVENT_MATCH / EVENT_EXCLUDE (regex, optional) - REPO_MATCH / REPO_EXCLUDE (regex, optional) - ACTOR_MATCH / ACTOR_EXCLUDE (regex, optional) - FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

gh run view <run-id> --attempt <attempt> \
  --json databaseId,runAttempt,workflowName,event,headBranch,headSha,conclusion,createdAt,updatedAt,runStartedAt,url,repository,actor,triggeringActor \
  > artifacts/github-actions/run-<run-id>-attempt-<attempt>.json

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
bash skills/github-actions-rerun-effectiveness-audit/scripts/rerun-effectiveness-audit.sh

JSON output + fail gate:

RUN_GLOB='artifacts/github-actions/*.json' \
OUTPUT_FORMAT=json \
FAIL_ON_CRITICAL=1 \
bash skills/github-actions-rerun-effectiveness-audit/scripts/rerun-effectiveness-audit.sh

Run against bundled fixtures:

RUN_GLOB='skills/github-actions-rerun-effectiveness-audit/fixtures/*.json' \
bash skills/github-actions-rerun-effectiveness-audit/scripts/rerun-effectiveness-audit.sh

Output contract

• Exit 0 in report mode (default)
• Exit 1 when FAIL_ON_CRITICAL=1 and one or more groups are critical

• Text mode prints summary + ranked workflow groups
• JSON mode prints summary + ranked groups + critical groups

這個 Skill 質量良好，能有效審計 GitHub Actions 的重新執行效果。優點是引數豐富、過濾靈活、輸出格式可選擇，錯誤處理到位。不足是缺少測試用例和示例資料，文件與實際內容存在小偏差，入手學習時可能遇到障礙。
