A working product *and* an active\nresearch project on coding-agent collaboration.**\n\nQuill mediates dialogue between the AI doing the work and a second AI\ngiving perspective. The headline: **if you have a Claude Pro and a Codex\nPro subscription, you have a free dual-AI coding setup.** No API key\nrequired, no per-token cost — Quill shells out to whichever CLIs you have\ninstalled and relays their conversation.\n\nBuilt by [YG3](https://yg3.ai). See\n[RESEARCH.md](RESEARCH.md) for the research direction.\n\nFour skills available in any agentic CLI Quill is installed in:\n\n- **`consult`** — for stuck/frustrated moments. Quill's advisor reframes\n  what's actually going on.\n- **`perspective`** — for exploring/curious moments. Layers in a vantage\n  the doer hasn't taken.\n- **`assumptions`** — for \"what choices is the AI making that I don't\n  understand?\" Translates technical assumptions into plain-language\n  yes/no questions.\n- **`mosaic`** *(new in v0.2)* — for multi-aspect tasks. Decomposes the\n  task into 2-4 voice-assigned slices, runs them in parallel with\n  independent priors preserved, cross-reviews for consistency without\n  homogenizing voice. The seams between agents stay visible *on\n  purpose* — preserved texture diversity is the value. See\n  [MOSAIC_DESIGN.md](MOSAIC_DESIGN.md) for the design rationale.\n\nIn Claude Code specifically, you also get safety hooks (gatekeeper for\nrisky shell commands) and pre-push quality scans (secrets, debug\nstatements, TODOs, .env files).\n\n## The four ways to run Quill\n\nPick the doer (the agent in your terminal) × the advisor (who Quill\ncalls when you ask for perspective):\n\n| Doer (your terminal) | Advisor (Quill calls) | Cost | Setup |\n|---|---|---|---|\n| **Claude Code** | **Codex CLI** | Free (Codex Pro) | `ADVISOR_BACKEND=codex_cli` |\n| **Codex CLI** | **Claude CLI** | Free (Claude Pro) | `ADVISOR_BACKEND=claud…","publisher":{"name":"Jacqueline Carter, Sam Knox, Partha Unnava","url":null},"homepage":"https://github.com/YG3-ai/quill","repository":"https://github.com/YG3-ai/quill","version":"0.2.1","license":"MIT License\n        \n        Copyright (c) 2026 YG3\n        \n  …","protocols":["mcp"],"tags":["mcp","model-context-protocol","claude","codex","coding-agent","ai","thinking-partner","agent-collaboration"],"pricing":null,"endpoints":[{"url":"pypi:quill-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"code.generation","name":"Code Generation","confidence":1,"provenance":"derived"},{"slug":"dev.terminal","name":"Terminal & Shell","confidence":1,"provenance":"derived"},{"slug":"productivity.tasks","name":"Tasks & To-do","confidence":1,"provenance":"derived"}],"categories":["code","dev","productivity"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"quill-mcp","registry":"pypi","observedAt":"2026-10-22T18:29:08.405Z","publishedAt":"2026-05-16T16:10:51.131101Z","latestVersion":"0.2.1"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"quill-mcp","url":"https://pypi.org/project/quill-mcp/","firstSeenAt":"2026-09-10T10:25:18.279Z","fetchedAt":"2026-10-22T18:27:53.891Z","normalizedAt":"2026-10-22T18:27:53.891Z"}]},"firstSeenAt":"2026-09-10T10:25:18.279Z","updatedAt":"2026-10-22T18:29:08.405Z"}
