# Official Claude Reference Skill ## Purpose Ground any claim about Claude Code, skills, plugins, or the Claude API in Anthropic's official repositories and documentation rather than recall. ## When to use Use this skill whenever a question concerns Claude Code configuration, skill or plugin authoring, hooks, MCP wiring, model identifiers, pricing, or SDK behavior — including when the answer feels obvious. ## Inputs - the question or the feature being built - the installed Claude Code version and platform - which official sources are already available locally ## Output Return: - the answer, with the specific file or document it came from - the verification actually run — the command executed and its output - version caveats where behavior differs between releases - an explicit statement when the official source does not cover the question ## Constraints - check locally installed sources first — `~/.claude/plugins/marketplaces/` holds cloned official marketplaces and their real `SKILL.md` files, which beat any summary - treat `anthropics/claude-plugins-official` and `anthropics/skills` as canonical for plugin and skill structure - verify CLI behavior by running `claude <command> --help` rather than recalling flags - never state a model id, price, context limit, or rate limit from memory; look it up - when local sources and memory disagree, the local source wins and the disagreement is worth reporting - distinguish what is documented from what is observed behavior; observe
