GitHub Actions Queue Latency Audit

Audit GitHub Actions queue wait hotspots from run/job JSON so CI bottlenecks are visible before they stall merges.

Use this skill to quantify where workflows are waiting in queue before jobs start.

What this skill does

• Reads one or more GitHub Actions run JSON exports (from gh run view --json ...)
• Computes per-job queue wait (startedAt - createdAt) and runtime duration (completedAt - startedAt)
• Groups repeated jobs by repository + workflow + job name
• Ranks hotspots by worst queue wait and average queue wait
• Flags warning/critical queue waits with configurable thresholds
• Emits output as human-readable text or machine-readable JSON

Inputs

Optional:

• RUN_GLOB (default: artifacts/github-actions/*.json)
• TOP_N (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• QUEUE_WARN_SECONDS (default: 120)
• QUEUE_CRITICAL_SECONDS (default: 300)
• FAIL_ON_CRITICAL (0 or 1, default: 0) — exit non-zero when any job instance hits/exceeds critical queue wait
• WORKFLOW_MATCH (regex, optional)
• WORKFLOW_EXCLUDE (regex, optional)
• JOB_MATCH (regex, optional)
• JOB_EXCLUDE (regex, optional)
• REPO_MATCH (regex, optional)
• REPO_EXCLUDE (regex, optional)

Collect run JSON

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

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
TOP_N=15 \
QUEUE_WARN_SECONDS=180 \
QUEUE_CRITICAL_SECONDS=420 \
bash skills/github-actions-queue-latency-audit/scripts/queue-latency-audit.sh

JSON output for dashboards:

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

Filter to one repo/workflow family:

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

Run with bundled fixtures:

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

Output contract

• Exit 0 in reporting mode (default)
• Exit 1 if FAIL_ON_CRITICAL=1 and at least one job instance has queue wait >= QUEUE_CRITICAL_SECONDS
• In text mode: prints summary + top queue hotspots
• In json mode: prints summary + grouped hotspot records + raw offending instances
