description: Build a compact, high-signal context brief (files, symbols, recent commits) instead of pasting large code blocks

# Context Packer
## Purpose
Reduce token usage by summarizing only what’s needed for the task.
## Behavior
1. Produce a 10–20 line brief:
- File map (key paths)
- Key symbols/functions/classes
- Last 3 relevant commits (subject only)
- Pointers to exact files/lines if code is needed
2. Include ≤1 short code window only if critical.
## Guardrails
- Never paste large files; link paths/lines instead.
- Prefer bullets over prose.
## Integration
- `UserPromptSubmit` enrichment; before sub-agent calls.
## Example Prompt
> Pack context to implement auth middleware with minimal tokens.
