# Agent skills for GitHub Actions

Skills your coding agent runs against your own repository, on your own machine.

## Install

```sh
npx skills add starslingdev/skills
```

All skills live in one repository: https://github.com/starslingdev/skills

## The skills

### Fix slow GitHub Actions with /ci-speedup

What it measures: wall clock. Measured in minutes from your real runs.

ci-speedup samples your own Actions runs, finds the check that gates your pull requests, and hands your coding agent the evidence to shorten it.

Wall-clock is a different question, and deliberately not part of this grade.

Invoke it with `/ci-speedup` after installing, or paste this prompt into your coding agent:

```text
Run `npx skills use "https://github.com/starslingdev/skills" --skill "ci-speedup"` and follow the generated skill instructions now. Read its complete output, redirecting it to a temporary file first if necessary. Resolve relative paths from the supporting-files directory it provides.
```

Open source, MIT licensed. Runs on your machine.

### Improve your GitHub Actions setup with /ci-score

What it measures: configuration. Graded pass/fail against a published rubric.

ci-score reads a local checkout, grades it against the best-practice rubric we publish, and ranks a fix for every gap it finds.

How long a run takes is one question. Whether the workflow follows the practices that keep it short is a different one.

Invoke it with `/ci-score` after installing, or paste this prompt into your coding agent:

```text
Run `npx skills use "https://github.com/starslingdev/skills" --skill "ci-score"` and follow the generated skill instructions now. Read its complete output, redirecting it to a temporary file first if necessary. Resolve relative paths from the supporting-files directory it provides.
```
