# Token Pruning Efficiency Plan Captured

## Summary

Captured a concrete implementation plan for reducing token estimation overhead in `prune_old_tool_outputs()`, including reuse of precomputed token counts, cached placeholder tokens, early termination in Phase 1, and a decision gate for token caching.

## Context

- Plan file: `memory-bank/plan/2026-02-02_token-pruning-efficiency-plan.md`
- Research source: `memory-bank/research/2026-02-02_token_estimation_overhead.md`

## Next Steps

- Execute milestones M1–M3 once scope is approved
- Decide on caching strategy (M4)
