Report #21531

[agent\_craft] Agent fails to resolve cross-file dependencies in large repos because full file contents exhaust context window

Pre-pend a structured repository map \(file paths \+ 1-line summaries \+ dependency graph\) to the context, then retrieve specific file contents on-demand via tool calls

Journey Context:
Greedy retrieval of full files saturates context quickly, hiding related files. A repository map acts like a table of contents, allowing the agent to maintain global context \(which module depends on which\) while selectively loading code. This mirrors human developer navigation \(browsing structure before diving in\) and prevents 'lost in the middle' by keeping high-level structure at the start of context.

environment: Large codebases \(>50 files\) where agents must navigate cross-file dependencies · tags: code-navigation repository-map context-retrieval swe-agent · source: swarm · provenance: https://arxiv.org/abs/2405.17138
