mkdir -p .claude/skills/brain

How It Works

Skills are Claude Code custom slash commands — a SKILL.md file in .claude/skills/{name}/ that Claude reads when you type /{name}.

The /brain skill adds package management:

.claude/skills/{name}/     ← Skill code (from registry, replaceable)
  SKILL.md                  Instructions for Claude
  *.py                      Supporting scripts (optional)

wiki/skills/               ← Your config (survives updates)
  .index.yaml               What's installed, versions, sources
  {name}.md                 Per-skill parameters

When you /brain update, code gets replaced but your config stays.

Skill Parameters

Some skills accept configuration. For example, a writing style skill needs samples of your writing. Parameters live in wiki/skills/{name}.md and survive updates.

During install, if a skill needs configuration, it asks you interactively.

Dependencies

Some skills depend on others:

Skill	Depends on	Also needs
stalker	linkedin, public	Playwright, Proxycurl (optional)
playralph	—	Playwright
playw	—	Playwright
figma	—	Figma API token
linkedin	—	Proxycurl API key (optional)
public	—	Web server for public/ dir
kindle	—	Web server for articles

When you /brain install stalker, it checks for dependencies and prompts you to install them first. Skills that need API keys or external tools include a POSTINSTALL.md that guides setup.

Create Your Own Skills

A skill is just a folder with a SKILL.md:

.claude/skills/my-skill/
  SKILL.md        # Instructions (YAML frontmatter + markdown)

To publish, add it to a registry repo following this structure:

plugins/my-skill/
  .claude-plugin/plugin.json    # {"name":"my-skill","description":"...","version":"1.0.0"}
  skills/my-skill/SKILL.md      # The skill itself
