Non-negotiable rules:

1. Read references/claude-agent-runtime.md before planning or rewriting.
2. Default to --mode plan unless the user explicitly asks for rewrite now.
3. Keep the body lean because the full markdown body becomes the agent system prompt.
4. Use frontmatter for runtime controls before adding more prose.
5. Never preload large skills into agent frontmatter unless they have already been slimmed and justified.
6. Never add skill-only frontmatter to an agent. allowed-tools, argument-hint, arguments, when_to_use, disable-model-invocation, user-invocable, context, agent, shell, and paths belong to skills, not agents.
