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.
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.
Some skills depend on others:
| Skill | Depends on | Also needs |
|---|---|---|
| stalker | linkedin, public | Playwright, Proxycurl (optional) |
| playralph | — | Playwright |
| playw | — | Playwright |
| figma | — | Figma API token |
| — | 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.
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
