# 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
