## Context Usage Analysis

**Estimated tokens:** ~45,000 / 200,000 (22.5%)

**Recommendation:** ✅ **No compaction needed**

**Reasoning:**

- Context usage is well below threshold (22.5%)
- All session summaries and documentation are concise
- No redundant or bloated content
- Working set fits comfortably in context window

**Next compaction recommended:** When context reaches 150,000 tokens (75%)
