GitHub Actions Branch Drift Audit

Use this skill to catch branch-specific CI reliability regressions before they spread into your mainline release flow.

What this skill does

• Reads GitHub Actions run JSON exports
• Groups runs by repository + workflow + branch
• Selects a baseline branch per repository/workflow (defaults to main|master)
• Compares each non-baseline branch against that baseline on:
• failure-rate drift (percentage points)
• average runtime drift (ratio)
• Flags warning/critical drift severity and supports CI fail gates
• Emits text or JSON output for pipeline checks and triage dashboards

Inputs

Optional: - RUN_GLOB (default: artifacts/github-actions/*.json) - TOP_N (default: 20) - OUTPUT_FORMAT (text or json, default: text) - MIN_RUNS_PER_BRANCH (default: 2) - MIN_BRANCHES (default: 2) - BASELINE_BRANCH_MATCH (default: ^(main|master)$) - WORKFLOW_MATCH (regex, optional) - WORKFLOW_EXCLUDE (regex, optional) - REPO_MATCH (regex, optional) - REPO_EXCLUDE (regex, optional) - FAILURE_DRIFT_WARN_PP (default: 10) - FAILURE_DRIFT_CRITICAL_PP (default: 25) - RUNTIME_DRIFT_WARN_RATIO (default: 1.25) - RUNTIME_DRIFT_CRITICAL_RATIO (default: 1.6) - FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

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

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
BASELINE_BRANCH_MATCH='^(main|release/.*)$' \
MIN_RUNS_PER_BRANCH=3 \
bash skills/github-actions-branch-drift-audit/scripts/branch-drift-audit.sh

JSON output with fail gate:

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

Run with bundled fixtures:

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

Output contract

• Exit 0 in report mode (default)
• Exit 1 when FAIL_ON_CRITICAL=1 and one or more drift rows are critical
• Text mode prints summary + ranked branch drift rows

• JSON mode prints summary + drift rows + critical-only slice

這個 Skill 質量較好，能有效檢測分支間的 CI 失敗率和執行時漂移問題。配置靈活、輸出清晰，適合整合到 CI 流程中。文件基本夠用但可更完善，缺少自動化測試略有遺憾。整體而言是一個實用且實現完整的工具類 Skill。
