Reference

Navigable registry of artifact classes with paths and on-disk layouts for rules, commands, skills, delegated workers, hooks, MCP servers, settings, and output styles.

Per-artifact-class reference. Each page describes the class's purpose, on-disk layout, frontmatter contract, and the registry that lists every instance.

Repo-relative paths are shown below; each adapter materializes these into its native configuration directory (e.g. ~/.claude/ for the Claude Code adapter — see site/content/docs/harnesses/<harness>.mdx for per-harness destinations).

Class	Page	Repo-relative source path
`CLAUDE.md`	CLAUDE.md	`CLAUDE.md`
Rules	Rules	`src/apothem/rules/`
Commands	Commands	`src/apothem/commands/`
Skills	Skills	`src/apothem/skills/`
Delegated workers	reference page	see canonical-paths block
Hooks	Hooks	`src/apothem/hooks/`
MCP servers	MCP servers	shared profile — `mcp_servers`
Settings	Settings	`src/apothem/harnesses/claude_code/templates/settings.json`
Output styles	Output styles	`src/apothem/output-styles/`
Harness registry	Harness registry	`src/apothem/lib/harness_registry.py`

The full canonical registry lives across the artifact cohorts (rules/, commands/, skills/, agents/, hooks/). This page mirrors that registry in a navigable form.
