GitHub Actions Timeout Risk Audit

Use this skill to find GitHub Actions jobs that are timing out or trending dangerously close to timeout limits.

What this skill does

• Reads one or more run JSON exports (gh run view --json ...)
• Calculates per-job runtime (completedAt - startedAt)
• Flags risk severity by configured timeout threshold:

- warn when runtime exceeds WARN_RATIO * JOB_TIMEOUT_SECONDS - critical when runtime exceeds CRITICAL_RATIO * JOB_TIMEOUT_SECONDS - always critical for jobs with conclusion=timed_out

• Groups repeated jobs by repository + workflow + job name
• Emits text or JSON output for CI gates / dashboards

Inputs

Optional:

• RUN_GLOB (default: artifacts/github-actions/*.json)
• TOP_N (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• JOB_TIMEOUT_SECONDS (default: 3600)
• WARN_RATIO (default: 0.80)
• CRITICAL_RATIO (default: 0.95)
• FAIL_ON_CRITICAL (0 or 1, default: 0)
• WORKFLOW_MATCH, WORKFLOW_EXCLUDE (regex, optional)
• JOB_MATCH, JOB_EXCLUDE (regex, optional)
• REPO_MATCH, REPO_EXCLUDE (regex, optional)
• BRANCH_MATCH, BRANCH_EXCLUDE (regex, optional)

Collect run JSON

gh run view <run-id> --json databaseId,workflowName,headBranch,url,repository,jobs \
  > artifacts/github-actions/run-<run-id>.json

Ensure jobs includes startedAt, completedAt, and conclusion.

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
JOB_TIMEOUT_SECONDS=3600 \
WARN_RATIO=0.85 \
CRITICAL_RATIO=0.95 \
bash skills/github-actions-timeout-risk-audit/scripts/timeout-risk-audit.sh

JSON output + fail gate:

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

Repo/workflow filter:

RUN_GLOB='artifacts/github-actions/*.json' \
REPO_MATCH='^flowcreatebot/' \
WORKFLOW_MATCH='(CI|Build)' \
bash skills/github-actions-timeout-risk-audit/scripts/timeout-risk-audit.sh

Run with bundled fixtures:

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

Output contract

• Exit 0 in reporting mode
• Exit 1 when FAIL_ON_CRITICAL=1 and at least one critical instance exists
• Text output includes summary, thresholds, and top timeout-risk jobs
• JSON output includes summary, ranked groups, and critical_instances
