GitHub Actions Actor Reliability Audit

Use this skill to rank which actors (humans or bots) are associated with the least reliable GitHub Actions outcomes.

What this skill does

• Reads GitHub Actions run JSON exports
• Groups runs by actor (optionally actor + workflow)
• Measures failure rate, failed-run volume, and latest failure streak per actor
• Scores severity (ok, warn, critical) for triage and CI policy gates
• Emits text or JSON output for automation

Inputs

Optional:

• RUN_GLOB (default: artifacts/github-actions/*.json)
• TOP_N (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• GROUP_BY (actor or actor-workflow, default: actor)
• FAILURE_CONCLUSIONS (comma-separated, default: failure,cancelled,timed_out,startup_failure)
• MIN_RUNS (minimum runs required, default: 5)
• WARN_FAILURE_RATE (0..1, default: 0.25)
• CRITICAL_FAILURE_RATE (0..1, default: 0.5)
• WARN_FAILED_RUNS (default: 4)
• CRITICAL_FAILED_RUNS (default: 8)
• WARN_FAILURE_STREAK (default: 2)
• CRITICAL_FAILURE_STREAK (default: 4)
• ACTOR_MATCH / ACTOR_EXCLUDE (regex, optional)
• WORKFLOW_MATCH / WORKFLOW_EXCLUDE (regex, optional)
• BRANCH_MATCH / BRANCH_EXCLUDE (regex, optional)
• EVENT_MATCH / EVENT_EXCLUDE (regex, optional)
• REPO_MATCH / REPO_EXCLUDE (regex, optional)
• FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

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

Run

Text report:

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

JSON output + fail gate:

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

Run against bundled fixtures:

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

Output contract

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

這個Skill質量不錯，功能實用，能幫助找出GitHub Actions中表現最差的貢獻者。文件清晰、配置靈活，錯誤提示友好，輸出結果可直接用於自動化流程。不足之處是缺少示例資料來演示效果，也沒有配套測試，建議補充完整的測試用例。
