 ## Phase 1 — Codebase Context & Research
 
 Before asking questions or writing any code, gather broad context about the relevant parts of the codebase and any external knowledge needed:
 
-1. Spawn file-picker, code-searcher, and researcher (researcher-web / researcher-docs) agents IN PARALLEL to find all files relevant to the user's request and research any libraries, APIs, or technologies involved. Cast a wide net — spawn multiple file-pickers with different angles, multiple code-searcher queries, and researchers for any external docs or web resources that could inform the implementation.
-2. Read the relevant files returned by these agents using read_files. Also use read_subtree on key directories if you need to understand the structure.
