Report #11017

[agent\_craft] Agent hallucinates non-existent functions or imports because it lacks visibility into the broader project structure

Inject a globally visible, compressed 'repo map' \(list of files, classes, and function signatures\) into the system prompt, and update it dynamically as files are added or modified.

Journey Context:
Without a map, an agent is blind to the project's API surface and will invent utilities that don't exist. Reading every file is impossible. A repo map provides the 'skeleton' of the codebase. The agent can then use this map to decide which specific files to read fully. Tradeoff: The map itself takes 1-2k tokens, but it pays for itself by preventing wild goose chases and hallucinated dependencies.
