Make the contract match the behavior.
I trace small failures in shared tools back to their boundary: an oversized schema, a lingering environment flag, or metadata that never reaches its consumer.
My role
I authored scoped patches and regression tests in forks, then opened upstream pull requests with the reproduction, measured result and remaining limits.
Where it stands
Submitted upstream pull requests, open at the November 4, 2026 review. These are proposed fixes, not claims of merged releases.
What changed.
In a Notion MCP patch, the measured tools/list response fell from 76,259 to 23,749 bytes while retaining referenced definitions.
A smaller tool contract
The Notion MCP converter attached every component definition to every tool. I changed it to retain only definitions reachable from that tool’s input parameters, following nested references and cycles. The measurement is response bytes, not tokens or a measured model-speed improvement.
Restore the state you borrowed
In Palantir’s OAuth client, a temporary environment variable stayed enabled after a token exchange when it had originally been absent. My patch removes it in that case and preserves a prior value. The process-global concurrency limitation remains; I did not claim to solve it.
A useful review starts with limits
Each PR records what the tests cover and what I did not run. A passing local regression demonstrates the patch’s intended behavior; it does not substitute for the maintainer’s review, every supported platform or a real client integration.
