@jacqueline-1929checks…add-quill → master2 files · +13 −0updated 3w ago@jacqueline-1929checks…add-quill → master2 files · +13 −0updated 3w agoQuill is an MCP server + Claude Code plugin that mediates dialogue between two coding AIs — one does the work, the other gives perspective. You see what they agree on, what they disagree on, and what one spotted that the other missed.
Free on existing subscriptions. If you have Claude Pro + ChatGPT Plus (or vice versa), you already have two AIs. Quill lets them talk to each other — no API key, no per-token cost.
Research-tested. 4/4 wins on decisions-under-tension tasks vs single AI, judged blind by a neutral third model (Gemini). Full methodology in the repo.
Works everywhere MCP does. Claude Code, Codex CLI, Cursor, Cline, Continue.
