GitHub Actions Duplicate Run Audit

Use this skill to detect accidental duplicate workflow execution bursts (for example trigger overlap, force-push storms, or retried dispatches) and measure wasted CI minutes.

What this skill does

  • Reads GitHub Actions run JSON exports
  • Groups runs by repository + workflow + branch + event + commit SHA
  • Clusters bursts where runs happen inside a configurable time window
  • Counts duplicate runs and estimates wasted runtime minutes
  • Scores severity (ok, warn, critical) for CI hygiene enforcement
  • Emits text or JSON for automation

Inputs

Optional: - RUN_GLOB (default: artifacts/github-actions/*.json) - TOP_N (default: 20) - OUTPUT_FORMAT (text or json, default: text) - DUPLICATE_WINDOW_MINUTES (default: 30) - MIN_DUPLICATE_RUNS (default: 2) - WARN_DUPLICATE_RUNS (default: 3) - CRITICAL_DUPLICATE_RUNS (default: 6) - WARN_WASTED_MINUTES (default: 20) - CRITICAL_WASTED_MINUTES (default: 60) - WORKFLOW_MATCH (regex, optional) - WORKFLOW_EXCLUDE (regex, optional) - BRANCH_MATCH (regex, optional) - BRANCH_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) - 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' 
DUPLICATE_WINDOW_MINUTES=20 
bash skills/github-actions-duplicate-run-audit/scripts/duplicate-run-audit.sh

JSON output + fail gate:

RUN_GLOB='artifacts/github-actions/*.json' 
OUTPUT_FORMAT=json 
FAIL_ON_CRITICAL=1 
bash skills/github-actions-duplicate-run-audit/scripts/duplicate-run-audit.sh

Run against bundled fixtures:

RUN_GLOB='skills/github-actions-duplicate-run-audit/fixtures/*.json' 
bash skills/github-actions-duplicate-run-audit/scripts/duplicate-run-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 duplicate-run groups
  • JSON mode prints summary + ranked groups + critical groups
