Report #5253

[agent\_craft] Agent exceeds context window when given large codebases, losing track of recent edits and failing to maintain consistency across files

Implement a sliding priority queue: 1\) Recent user messages \(100%\), 2\) Files modified in last 3 turns \(100% full content\), 3\) Open files in working set \(signatures \+ imports only\), 4\) Repo map \(file paths only\). Evict from bottom up when token budget hits 70% of max.

Journey Context:
Naive RAG retrieves semantically similar chunks, but coding requires temporal locality \(what you just changed\) and structural locality \(imports/definitions\). The 'hierarchical' approach prioritizes recent edits over semantic similarity because code consistency depends on the last 3 turns of conversation. The 70% threshold leaves headroom for the model's response and tool call outputs \(which can be large\). This pattern comes from Aider's repo map strategy combined with Anthropic's findings on contextual retrieval, where file recency outweighs semantic similarity in code generation tasks.
