Report #7683

[agent\_craft] Repository context exceeds token limits, causing truncation of critical function definitions

Implement hierarchical context packing: Level 1 \(always included\) - current file and cursor position; Level 2 \(compressed\) - import graph neighbors with 3-line signatures; Level 3 \(summarized\) - directory structure and high-level module docs; Use importance sampling \(e.g., based on call frequency or recency\) rather than naive truncation

Journey Context:
Naive truncation \(dropping oldest tokens\) often removes import statements or class definitions while keeping boilerplate. RepoCoder research shows that retrieval-augmented context \(selecting relevant chunks via embedding similarity\) outperforms full-file context at 8k token budgets. Hierarchical packing respects the 'locality of reference' principle: nearby code in the import graph is more relevant than distant files. This pattern is used in Cursor and GitHub Copilot's context engines.
