GitHub Actions Incident Timeline Audit

Use this skill to convert noisy failed run exports into incident windows you can triage quickly during CI reliability reviews.

What this skill does

  • Reads GitHub Actions run JSON exports
  • Keeps only failed/cancelled/timed-out style outcomes
  • Groups failures by repository into incident windows using a configurable gap threshold
  • Scores each incident using failed-run and duration thresholds
  • Emits text or JSON output for review docs, ops dashboards, and CI fail gates

Inputs

Optional:

  • RUN_GLOB (default: artifacts/github-actions/*.json)
  • TOP_N (default: 20)
  • OUTPUT_FORMAT (text or json, default: text)
  • INCIDENT_GAP_MINUTES (default: 45)
  • WARN_FAILED_RUNS (default: 2)
  • CRITICAL_FAILED_RUNS (default: 4)
  • WARN_DURATION_MINUTES (default: 20)
  • CRITICAL_DURATION_MINUTES (default: 60)
  • WORKFLOW_MATCH (regex, optional)
  • WORKFLOW_EXCLUDE (regex, optional)
  • REPO_MATCH (regex, optional)
  • REPO_EXCLUDE (regex, optional)
  • FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

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

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
INCIDENT_GAP_MINUTES=45 \
bash skills/github-actions-incident-timeline-audit/scripts/incident-timeline-audit.sh

JSON output with fail gate:

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

Run with bundled fixtures:

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

Output contract

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