Description
Audit GitHub Actions mainline branch reliability by scoring failure rate, consecutive failures, and stale-success risk for critical workflows.
README (SKILL.md)

GitHub Actions Mainline Health Audit

Use this skill to detect unstable workflows on protected branches (main/master/release) before they silently degrade delivery confidence.

What this skill does

  • Reads GitHub Actions run JSON exports
  • Filters to mainline/protected branches (configurable regex)
  • Groups by repository + workflow + branch + event
  • Scores risk using:
    • failure rate
    • current consecutive failure streak
    • days since last successful run
  • Flags warning/critical groups based on configurable thresholds
  • Emits text or JSON output for CI checks and ops dashboards

Inputs

Optional:

  • RUN_GLOB (default: artifacts/github-actions/*.json)
  • TOP_N (default: 20)
  • OUTPUT_FORMAT (text or json, default: text)
  • MIN_RUNS (default: 2)
  • MAINLINE_BRANCH_MATCH (default: ^(main|master|release.*)$)
  • WORKFLOW_MATCH (regex, optional)
  • WORKFLOW_EXCLUDE (regex, optional)
  • EVENT_MATCH (regex, optional)
  • EVENT_EXCLUDE (regex, optional)
  • REPO_MATCH (regex, optional)
  • REPO_EXCLUDE (regex, optional)
  • HEAD_SHA_MATCH (regex, optional)
  • HEAD_SHA_EXCLUDE (regex, optional)
  • CONCLUSION_MATCH (regex, optional)
  • CONCLUSION_EXCLUDE (regex, optional)
  • RUN_ID_MATCH (regex, optional)
  • RUN_ID_EXCLUDE (regex, optional)
  • RUN_URL_MATCH (regex, optional)
  • RUN_URL_EXCLUDE (regex, optional)
  • FAIL_WARN_PERCENT (default: 20)
  • FAIL_CRITICAL_PERCENT (default: 40)
  • STALE_SUCCESS_DAYS (default: 7)
  • WARN_SCORE (default: 30)
  • CRITICAL_SCORE (default: 55)
  • FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

gh run view \x3Crun-id> --json databaseId,workflowName,event,conclusion,headBranch,headSha,createdAt,updatedAt,startedAt,url,repository \
  > artifacts/github-actions/run-\x3Crun-id>.json

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
MAINLINE_BRANCH_MATCH='^(main|release/.*)$' \
HEAD_SHA_MATCH='^[a-f0-9]{7,40}$' \
CONCLUSION_EXCLUDE='^(success)$' \
RUN_ID_MATCH='^50(0[1-5])$' \
MIN_RUNS=3 \
bash skills/github-actions-mainline-health-audit/scripts/mainline-health-audit.sh

JSON output with fail gate:

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

Run with bundled fixtures:

RUN_GLOB='skills/github-actions-mainline-health-audit/fixtures/*.json' \
bash skills/github-actions-mainline-health-audit/scripts/mainline-health-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 mainline-risk groups
  • JSON mode prints summary + scored groups + critical group details
Usage Guidance
This skill appears to be an offline auditor that consumes GitHub Actions run JSON files and emits scores/reports. Things to consider before installing/using: (1) The SKILL.md examples show using the `gh` CLI to produce run JSON files — ensure you have the GitHub CLI and appropriate auth configured if you use that collection method (the skill itself does not request GitHub credentials). (2) Confirm the RUN_GLOB path only matches intended JSON files (avoid accidentally exposing sensitive data). (3) Review the script if you plan to run it in CI to ensure its exit behavior (FAIL_ON_CRITICAL) and output format meet your pipeline expectations. (4) There are no network calls or credential exfiltration in the included code, but always review any third-party skill’s files before running in sensitive environments.
Capability Analysis
Type: OpenClaw Skill Name: github-actions-mainline-health-audit Version: 1.4.0 The skill bundle is a legitimate utility for auditing GitHub Actions workflow health by analyzing JSON run logs. The bash script (mainline-health-audit.sh) wraps a Python script that processes local files defined by a glob pattern, calculates risk scores based on failure rates and streaks, and generates reports. No evidence of malicious intent, data exfiltration, or unauthorized execution was found; the code logic is consistent with its stated purpose.
Capability Assessment
✓ Purpose & Capability
Name/description match behavior: the script and SKILL.md both describe reading GitHub Actions run JSON files, filtering mainline branches, scoring failure/stale-success risk, and emitting text/JSON reports. One minor documentation gap: SKILL.md shows using the `gh` CLI to collect run JSON, but the declared required binaries list only bash and python3 (the script itself does not invoke `gh`).
✓ Instruction Scope
Runtime instructions and the included script operate on local JSON files (RUN_GLOB) and environment-configurable filters; they do not instruct the agent to read unrelated system files, access secrets, or transmit data to external endpoints. The example `gh run view ... > artifacts/...` requires the user to run the GitHub CLI to produce input artifacts, but the skill itself only reads those local files.
✓ Install Mechanism
Instruction-only skill with an included script; there is no install spec, no downloads, and nothing is written to disk by an installer. The script is executed directly by bash/python3, which is proportionate for this purpose.
✓ Credentials
No required environment variables, credentials, or config paths are declared. The many optional environment variables documented are reasonable filters/thresholds for the audit and do not request secrets. Note: using `gh` to collect run JSON (per examples) requires GitHub CLI authentication in the user's environment, but that is external to the skill.
✓ Persistence & Privilege
Skill does not request permanent presence (always=false) and does not modify other skills or system-wide agent settings. It runs on demand and only reads local files provided via RUN_GLOB.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install github-actions-mainline-health-audit
  3. After installation, invoke the skill by name or use /github-actions-mainline-health-audit
  4. Provide required inputs per the skill's parameter spec and get structured output
