Report #15297

[agent\_craft] RAG pipeline retrieves entire files or flat-text chunks, diluting the context window with boilerplate and breaking code logic

Implement code-aware chunking using Abstract Syntax Trees \(AST\) to split code at function or class boundaries, and retrieve only the precise signatures or snippets needed.

Journey Context:
Flat text chunking \(e.g., splitting by 500 tokens\) breaks functions in half, making retrieved context syntactically invalid and semantically confusing. Retrieving whole files fills the window with imports and whitespace. AST chunking preserves logical units, allowing the agent to understand the code structure without noise.
