skill-authoring-guide skillA

skill-authoring-guide is agent-read markdown (skill) from yeaight7/agent-powerups: Create or refactor high-quality skills with lean frontmatter, progressive disclosure, and optional bundled helpers. Use when authoring reusable agent workflows..

Indexed from public GitHub and served as immutable, content-addressed versions.

The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Skill Authoring Guide

Use this skill when creating or improving a reusable skill.

## What Good Skills Do

- Trigger reliably from `name` and `description` — the description must be specific enough to avoid false triggers.
- Stay short in `SKILL.md` and move bulk detail into `references/` or `scripts/`.
- Teach a **workflow or decision pattern**, not just dump background information.
- Include scripts or references only when they eliminate repeated work or prevent ambiguity.

## Frontmatter Template

```yaml
---
name: kebab-case-matching-directory-name
description: Use when [trigger condition]. Does [what it does]. [Optional: NOT for X.]
---
```

## Body Format

Default to a pure Markdown body after the YAML frontmatter. Use headings such as `## Purpose`, `## When to Use`, `## Workflow`, and `## Verification`. Do not use XML-like tags such as `<Purpose>`, `<Workflow>`, or `<Use_When>` as normal top-level sections. XML-like tags are acceptable only when they strictly delimit nested examples, quoted input, external documents, or machine-readable prompt payloads.

**Good description** (specific, trigger-clear):

```
