Report #13123

[agent\_craft] System prompt exceeds token limits or dilutes agent focus by including entire codebase structure

Use a dynamic task-aware system prompt. Inject only the high-level architecture and the specific module interfaces relevant to the current sub-task, rather than the entire repository tree. Use an AST-based repo map to provide just signatures, not implementations.

Journey Context:
Developers often try to cram the whole repo map into the system prompt so the agent knows everything. This causes attention dilution. The agent gets overwhelmed by irrelevant class signatures. A dynamic system prompt, updated based on the current file being edited, provides high-signal context while staying within token limits. Tree-sitter provides deterministic, up-to-date signatures without LLM summarization overhead.
