GitHub Actions Trigger Health Audit

Use this skill to find which GitHub Actions trigger events are driving the highest failure rates.

What this skill does

• Reads one or more GitHub Actions run JSON exports
• Groups runs by repository + event + workflow
• Calculates failure/cancel/timeout rates and average runtime
• Flags warning/critical hotspots based on configurable failure-rate thresholds
• Supports regex include/exclude filters for repo, workflow, and event
• Emits text or JSON output for dashboards and automation gates

Inputs

Optional:

• RUN_GLOB (default: artifacts/github-actions/*.json)
• TOP_N (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• MIN_RUNS (default: 2) — skip low-sample groups
• FAIL_WARN_PERCENT (default: 20)
• FAIL_CRITICAL_PERCENT (default: 40)
• FAIL_ON_CRITICAL (0 or 1, default: 0)
• WORKFLOW_MATCH (regex, optional)
• WORKFLOW_EXCLUDE (regex, optional)
• EVENT_MATCH (regex, optional)
• EVENT_EXCLUDE (regex, optional)
• REPO_MATCH (regex, optional)
• REPO_EXCLUDE (regex, optional)

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' \
MIN_RUNS=3 \
FAIL_WARN_PERCENT=25 \
FAIL_CRITICAL_PERCENT=50 \
bash skills/github-actions-trigger-health-audit/scripts/trigger-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-trigger-health-audit/scripts/trigger-health-audit.sh

Run with bundled fixtures:

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

Output contract

• Exit 0 in report mode (default)
• Exit 1 when FAIL_ON_CRITICAL=1 and any group meets critical threshold
• Text mode prints summary + ranked trigger health hotspots
• JSON mode prints summary + grouped metrics + critical group details
