skills AGENTS.md

Repository instructions for StarSling's public AI-agent skills, currently centered on a skill that audits GitHub Actions workflows. GitHub Actions is GitHub's system for running automated build and test jobs.

In plain words
What is it for?
Maintaining the CI-speedup skill, understanding its scripts and references, and following the repository's testing and pull-request process.
Why use it?
They explain the repository structure and identify the source files that govern changes. This helps an agent edit the CI-auditing skill consistently and run the expected checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

skills AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Instructions for coding agents contributing to starslingdev/skills.

AGENTS.md is the cross-tool convention (Codex, Cursor, and others read it). Claude Code reads CLAUDE.md — it carries the same rules in fuller form. This file is the contributor subset; when they disagree, the source files below win.

What this repo is

Public Claude Code skills from StarSling. Today it ships one skill, ci-speedup, self-contained under skills/ci-speedup/. ci-speedup audits a repository's GitHub Actions workflows for CI optimization opportunities and produces a prioritized report with measured wall-clock and runner-minute savings.

Read skills/ci-speedup/SKILL.md before editing anything under the skill — it is the authoritative spec.

Running tests

From the repo root:

pip install -e ".[dev]"    # pytest + PyYAML; the suite needs both
python3 -m pytest -v

This runs every suite — the root pyproject.toml wires the paths so one command finds tests under tests/, skills/ci-speedup/tests/, and maintainers/ci-speedup/tests/. CI runs the identical command, so green on your machine means green in CI — as long as the dev dependencies are installed. Without PyYAML, pytest aborts at collection with INTERNALERROR and runs nothing. Enable the local pre-commit hook to run the same suite before each commit:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
