Repo Context Packaging

Turn a repository into a single, token-efficient bundle an agent can reason over: a tree, the files that matter, and nothing that wastes the budget. Optimize for signal per token, not completeness.

When to use

• Onboarding an agent to an unfamiliar codebase for review, debugging, or a feature.
• The repo doesn't fit (or barely fits) in context and needs trimming.
• Producing a portable snapshot to paste into a model or attach to a task.

Skip when the task touches only a few known files — just read those directly.
