| What makes it different | - Checks code context outside the diff, not just the change itself
- Dual independent reviewer reconciliation catches contradictions humans need to judge
- Only grounded findings block; AI certainty is not enough
- Does not train on customer code and never will
- Integrates with coding agents before commit to catch issues early
| - Achieves 25-50% token reduction on typical Claude Code sessions without requiring model subscription upgrades
- All compression runs locally on your machine with no data sent to servers
- Reversible compression preserves output quality and allows retrieval of original content on demand
- Works transparently with existing IDE extensions and agent runners without workflow changes
- Built on open-source Headroom CLI engine available free on GitHub
