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.
