How to audit MCP tool schema token bloat and sync CLAUDE.md with AGENTS.md locally
If you connect 4–5 MCP servers to Claude Code or OpenAI Codex (GitHub, Playwright, Postgres, Notion), their tools/list JSON schemas silently consume 15,000–35,000 tokens on every turn before you even type a prompt.
On top of that, repositories using both Claude Code (CLAUDE.md) and OpenAI Codex (AGENTS.md) or Cursor (.cursor/rules) quickly suffer from rule drift or accidentally include exposed keys / covert prompt injections inside third-party skills.
I just released CtxWise v1.0 (@framy2/ctxwise, Apache-2.0, 100% local, zero API calls, zero telemetry) to inspect and fix all three in <50ms:
