[agent\_craft] Agent pastes entire codebase into context and then runs out of window

For codebases larger than ~50% of the available context window, stop dumping files and switch to a structured map: symbol index \(ctags/AST\), dependency graph, and a prioritized file list. Only load file bodies on demand after the retriever or user points to them.

Journey Context:
The 'read every file once' strategy works for prototypes but collapses on real projects. The temptation is to include everything 'just in case,' which crowds out the actual reasoning budget and forces premature compaction that strips comments and whitespace needed for accurate edits. Aider's repo map and Cursor's codebase indexing are built on this exact insight: an agent does not need full file text to know where to look. The map must include symbols, signatures, imports, and file relationships; bodies are fetched after search. The wrong turn is building a smarter dump instead of a map.
