[agent\_craft] Agent exhausts token budget when providing large codebases by naively concatenating files

Use hierarchical inlining: replace full function bodies with signatures and docstrings in "outline mode", inline only the specific function under edit plus its direct dependencies \(2-level call graph\), and use diff/patch notation for modifications rather than full file rewrites.

Journey Context:
Full file context quickly exhausts token budgets \(e.g., 128K tokens ≈ 96K words ≈ 3000 lines of dense code\). Hierarchical packing mimics IDE "go to definition" behavior - keeping interfaces in working memory while bodies are cold storage. Diff notation reduces token count by 10-100x for edits versus full rewrites. This pattern is essential for agents operating on large monorepos where naive context loading would truncate critical files.
