[agent\_craft] Loading an entire large repo into the context window exceeds limits and overwhelms the model

Build or use a queryable codebase index \(embeddings \+ sparse keyword \+ symbol dependency graph\) and retrieve only the files, functions, and call-graph neighbors relevant to the current task. For small repos or surgical edits, full-file loading can still win; for large repos, retrieval is mandatory.

Journey Context:
There are two competing philosophies: Claude Code loads files directly into a very large context window, while Cursor indexes the repo and retrieves snippets via @codebase. Direct loading gives the model complete file contents and exact line numbers but caps out around the window limit. Retrieval scales to monorepos but risks missing private helper functions and cross-file references. The practical answer is hybrid: maintain an offline index of symbols, imports, embeddings, and PageRank-style importance; at runtime, retrieve candidates, then follow import/caller edges to fill gaps. The dependency graph is the load-bearing signal that closes the 'where is this used' recall gap.
