I kept hitting context limits building coding agents because tool outputs explode (search/log/API payloads), and prompt compression breaks strict tool calling. Headroom is a local proxy / SDK wrapper that: - compresses tool outputs (schema-preserving subset of JSON arrays; keeps errors/anomalies/top/relevant) - trims history as whole tool-call units (no broken function calls) - stabilizes prefixes so provider caching stops getting invalidated by drift Try it locally: pip install "headroom-ai[proxy]" && headroom proxy --port 8787 then point your client’s base URL at it. Repo: https://github.com/chopratejas/headroom https://github.com/chopratejas/headroom Limitations: best on JSON arrays; text compression is opt-in; if you truly need every row, you’ll need the retrieval escape hatch or per-tool disable. Do give it a 'star' if you like it.
