changelog
actionlint checks your workflows for
*correctness*. zizmor checks them for
*security*. **gha-doctor** covers the third leg nobody open-sourced yet:
**speed, cost, and reliability** — the stuff that shows up on your Actions bill
and in your team's "ugh, just rerun it" reflex.
Run-history analysis — real output against the cli/cli repo (per-workflow success/p50/p95/queue/cost, flaky-job detection, slowest steps, wasted-minute and $ accounting)
Why you'd run it
- **Flake detection with receipts.** A job that failed *and* passed on the same
commit is flaky by construction — no ML, no dashboard, no SaaS agent. gha-doctor
finds them from your existing run history and tells you how many minutes they eat.
- **Cost checks that map to the bill.** Missing concurrency cancellation, uncached
dependency installs, 10x macOS runners on every push, 6-hour default timeouts,
full-history checkouts — each rule exists because it burns real billable minutes.
- **Zero config.** Run it inside a repo. It reads .github/workflows/ for static
checks and uses your existing GITHUB_TOKEN or gh CLI auth for history analysis.
No YAML to write, no account to create.
- **A number you can put in the README.** Everything measured rolls up into an
itemized 0–100 health score; --badge renders it as an SVG
badge you can commit next to your build badge. Curious how the big repos do?
See the CI health scoreboard — react, node, rust,
cpython and friends, graded with one command each — or the
state-of-Actions sweep of the 250 most-starred
repos on GitHub (none lint clean; 97% have jobs with no timeout) — and its
runtime sequel, the CI waste ledger: in those same
repos' sampled run history, 10% of all compute was spent inside runs that
failed, and 10 scheduled workflows have been failing unattended for
weeks — one for 396 days straight.
- **Works on repos you haven't cloned.** --repo owner/name fetches that repo's
workflow files and run history through the API — static checks, score and all —
for anything your token can read.
Install
**gh CLI extension** (any platform — you already have gh):
**Homebrew** (macOS / Linux):
**Scoop** (Windows):
**Docker** (multi-arch, works from any CI — GitLab, Jenkins, a cron job):
The image is distroless (CA certs included, no shell, runs as nonroot). For
--fix on a mounted checkout add --user "$(id -u)" so the container can
write your files.
**Go**:
**aqua** (in the standard registry):
**mise / ubi** (installs the checksummed release binary):
**asdf** (the plugin verifies release checksums):
or grab a binary from releases
(linux/macOS/windows, amd64/arm64). .deb, .rpm and .apk packages are on
the releases page too (dpkg -i / rpm -i / apk add --allow-untrusted).
**Shell completions** (bash/zsh/fish; Homebrew installs them automatically):
Completions know the rule IDs, so --explain D works.
**pre-commit** — lint workflow files on every commit (builds from source, needs Go):
The hooks only trigger when files under .github/workflows/ change.
Usage
Auth for history analysis: set GITHUB_TOKEN, or just be logged in with the
gh CLI — gha-doctor picks up gh auth token
automatically. --lint-only needs no auth at all.
Building on the --json output? Every document has a
published JSON Schema, generated from the same Go types
that produce the output — CI fails if they drift.
