GitHub Actions Rerun Effectiveness Audit

Use this skill to measure how often workflows require reruns and whether reruns are actually recovering failures.

What this skill does

Reads GitHub Actions run JSON exports

Tracks rerun episodes using workflow run id + attempt history

Measures rerun rate, rerun success rate, and extra rerun attempts

Estimates wasted rerun minutes from attempt durations

Emits severity (ok, warn, critical) for CI policy gates

Inputs

Optional:

RUN_GLOB (default: artifacts/github-actions/*.json)

TOP_N (default: 20)

OUTPUT_FORMAT (text or json, default: text)

GROUP_BY (workflow or workflow-branch, default: workflow)

FAILURE_CONCLUSIONS (comma-separated, default: failure,cancelled,timed_out,startup_failure,action_required)

SUCCESS_CONCLUSIONS (comma-separated, default: success)

MIN_RUNS (minimum workflow runs required, default: 4)

WARN_RERUN_RATE (0..1, default: 0.2)

CRITICAL_RERUN_RATE (0..1, default: 0.35)

WARN_RERUN_SUCCESS_RATE (0..1, default: 0.5)

CRITICAL_RERUN_SUCCESS_RATE (0..1, default: 0.25)

WARN_WASTED_MINUTES (default: 20)

CRITICAL_WASTED_MINUTES (default: 60)

WORKFLOW_MATCH / WORKFLOW_EXCLUDE (regex, optional)

BRANCH_MATCH / BRANCH_EXCLUDE (regex, optional)

EVENT_MATCH / EVENT_EXCLUDE (regex, optional)

REPO_MATCH / REPO_EXCLUDE (regex, optional)

ACTOR_MATCH / ACTOR_EXCLUDE (regex, optional)

FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

gh run view  --attempt  \
  --json databaseId,runAttempt,workflowName,event,headBranch,headSha,conclusion,createdAt,updatedAt,runStartedAt,url,repository,actor,triggeringActor \
  > artifacts/github-actions/run--attempt-.json

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
bash skills/github-actions-rerun-effectiveness-audit/scripts/rerun-effectiveness-audit.sh

JSON output + fail gate:

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

Run against bundled fixtures:

RUN_GLOB='skills/github-actions-rerun-effectiveness-audit/fixtures/*.json' \
bash skills/github-actions-rerun-effectiveness-audit/scripts/rerun-effectiveness-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 workflow groups

JSON mode prints summary + ranked groups + critical groups
