Report #6685

[agent\_craft] Agent wastes tokens on irrelevant code sections and truncates critical functions

Use three-tier hierarchical retrieval: Level 1 \(file summaries\), Level 2 \(signatures/definitions\), Level 3 \(full implementations\). Fill context window from top down, allowing clean truncation at tier boundaries

Journey Context:
Naive RAG for coding inserts raw file chunks, often cutting off mid-function or including boilerplate headers. This wastes precious context window. The hard-won pattern is hierarchical encoding: first retrieve relevant file paths with summaries \(cheap, high-signal\), then relevant function/class signatures from those files, then full bodies only for the most relevant signatures. This allows graceful degradation—if context runs out, you lose full implementations but keep the API contracts and structure, which is often sufficient for reasoning about dependencies and interfaces.
