## What it does

The skill structures instructions for coding agents around a single durable job. Instead of generating abstract boilerplate, it inspects your local workspace: neighboring skills, active agent definitions, and existing commands.

It keeps the core `SKILL.md` document lean. Goals, operational boundaries, and primary workflows stay in the main file, while exhaustive catalogs and templates move into `references/` or `examples/`. Every referenced helper script or guide must physically exist in the project directory.

Before finishing, the workflow runs local integrity checks on frontmatter parsing and path validity. It flags dead references immediately. If your instructions cite a non-existent sibling skill, the validation fails until you clean it up.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill skill-development -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/skill-development/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/skill-development/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill skill-development -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/skill-development/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill skill-development -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/skill-development/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Galaxy-Dawn/claude-scholar skill-development
```

2. **Manually: put the files in place**
- File: `.github/skills/skill-development/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill skill-development -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Galaxy-Dawn/claude-scholar --path skills/skill-development
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/skill-development/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Galaxy-Dawn/claude-scholar --skill skill-development -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Galaxy-Dawn/claude-scholar/tree/HEAD/skills/skill-development/SKILL.md

## When to use it
- create a clean skill contract with explicit boundaries
- extract large checklists and templates into `references/`
- rewrite frontmatter trigger descriptions for natural user queries
- remove dead paths and stale references to sibling agents
- run integrity checks on local skill directories

## Example prompts
- Create a new skill for database migrations and keep SKILL.md lean
- Audit the current skill directory for missing files and dead references
- Rewrite the frontmatter description to improve skill triggering

# Skill Development

Use this skill to create or repair Claude skills in the **current local environment**, not in an abstract plugin template.

## Goal

Produce a skill that is:
- easy to trigger,
- lean at the `SKILL.md` layer,
- backed by real `references/`, `examples/`, and `scripts/` files when they are mentioned,
- free of dead local references.

## Core rules

- Keep **one skill = one durable job**.
- Treat the frontmatter description as the main trigger surface.
- Keep `SKILL.md` focused on workflow and boundaries.
- Move detailed catalogs, templates, and long explanations into `references/` or `examples/`.
- Do not mention files that do not exist.
- Do not inherit stale names, agents, or sibling skill references without verifying they exist locally.

## Default workflow

### 1. Inspect the current environment first

Before writing anything:
- inspect the target skill directory,
- inspect neighboring skills that already solve a similar problem,
- verify which agents, commands, and sibling skills actually exist,
- identify stale references before adding new ones.

Use the local inventory as the authority. Do not write guidance against an imagined plugin layout.

### 2. Lock the skill contract

Define four things before editing:
1. what the skill does,
2. what triggers it,
3. what it explicitly does **not** do,
4. which bundled resources are actually needed.

If the skill only needs a short workflow, keep it short. Do not create `references/`, `examples/`, or `scripts/` just because the directories are conventional.

### 3. Write or repair the frontmatter

The frontmatter should:
- use the real skill identifier in `name`,
- use a third-person trigger description,
- include concrete phrases a user would naturally say,
- stay short enough to scan quickly.

Prefer descriptions of this form:

```yaml
---
name: skill-name
description: This skill should be used when the user asks to "...", "...", or needs help with ....
---
```

### 4. Keep the main file lean

A good `SKILL.md` should usually contain:
- a short goal section,
- role boundaries,
- a default workflow,
- safety or quality rules,
- a short list of additional resources.

Move these out of the main file when they get long:
- templates,
- exhaustive checklists,
- edge-case catalogs,
- sample outputs,
- long examples.

### 5. Add only real bundled resources

Use bundled resources deliberately:
- `references/` for detailed guidance that may be loaded selectively,
- `examples/` for real example outputs or scaffolds,
- `scripts/` for deterministic helper logic.
