BEFORE calling this tool, deeply explore the codebase:

144
1. Use search/read tools to find key files, entry points, and architecture patterns

83
152
- Descriptions: 2-3 paragraphs of markdown per node. Write for someone who has never seen this codebase — explain what the component does, how it works, and why it matters. Use \`code spans\` for identifiers and markdown headers to organize longer explanations
84
153
- Links: include file:line references from your exploration
