quintet

One orchestrator for five coding-agent CLIs. Quintet drives Claude Code, OpenAI Codex, Google Gemini, GitHub Copilot, and Qwen Code through a single entry point, in two complementary modes:

• Team mode — persistent worker processes in tmux panes that autonomously edit files and coordinate (the oh-my-claudecode omc-teams model, extended to Copilot and Qwen).
• Fleet mode — one-shot dispatch of a single prompt to many CLIs in parallel, with a circuit-breaker + fallback reliability layer and consult / debate / review flows (the claude-octopus model).

It is self-contained: no runtime dependency on omc or octo. The two upstream projects each covered one half — quintet unifies persistent tmux teams and multi-provider one-shot dispatch across the full set of five CLIs.

The novel capability quintet adds: running Copilot and Qwen as persistent coordinating tmux team workers, alongside Claude/Codex/Gemini, under one CLI.

Quintet ships as a plugin/extension for all four major coding-agent CLIs from one repo, distributed via the vdw-claude-plugins marketplace where supported.

Claude Code (marketplace):

/plugin marketplace add salemaziel/omc-octo-quintet
/plugin install quintet@vdw-claude-plugins

OpenAI Codex (marketplace): the repo ships .agents/plugins/marketplace.json. In Codex, run /plugins, switch to the vdw-claude-plugins marketplace tab, and install quintet.

Gemini CLI (extension):

gemini extensions install https://github.com/salemaziel/omc-octo-quintet

GitHub Copilot CLI (plugin): point Copilot at the repo's root plugin.json (it loads skills/ and the .copilot/agents/ conductor). Verify with /skills list and /agent.

Every ecosystem shells out to the same CLI at bin/quintet, bundled inside the installed plugin — quintet never touches your shell PATH. Each host locates it on its own:

• Claude Code runs it via the absolute ${CLAUDE_PLUGIN_ROOT}/bin/quintet, and also exposes the plugin's bin/ on the Bash tool's PATH only while the plugin is enabled (it does not modify your login shell).
• Codex sets CLAUDE_PLUGIN_ROOT for plugin compatibility, so the same skills resolve the binary there.
• Gemini finds it at ~/.gemini/extensions/quintet/bin/quintet.
• Copilot finds it under ~/.copilot/installed-plugins/.../quintet/bin/quintet.

Optional — only if you also want to run quintet by hand in a normal terminal:

ln -s "$PWD/bin/quintet" ~/.local/bin/quintet   # standalone CLI use, not required by any plugin
quintet doctor

Requirements: tmux (team mode only), jq (optional), and at least one of the agent CLIs installed and authenticated:

npm install -g @anthropic-ai/claude-code   # claude
npm install -g @openai/codex               # codex
npm install -g @google/gemini-cli          # gemini
npm install -g @github/copilot             # copilot   (or: brew install copilot-cli)
npm install -g @qwen-code/qwen-code        # qwen      (free OAuth tier)

# Team mode — persistent tmux workers
quintet team 2:codex,1:gemini,1:qwen "build the export feature" \
    --name export --cwd ./repo \
    --tasks "implement serializer||add tests||write docs||audit edge cases"
quintet team status export
quintet team capture export w1-codex 80
quintet team send export w2-gemini "focus on the v2 API"
quintet team shutdown export --force

# Fleet mode — one-shot across many models
quintet consult "best way to dedupe a 10M-row stream?" claude,codex,gemini
quintet debate  "gRPC or REST for this internal service?"
quintet review  "$(git diff HEAD~1)" claude,gemini,copilot

quintet doctor       # provider/tmux/jq readiness
quintet providers    # per-provider install/auth/ready

quintet-conductor — decomposes a task, picks providers, launches/monitors a team or fleet, and synthesizes results.

Adding a provider (e.g. ollama, cursor-agent) = one entry in QUINTET_PROVIDERS plus its cases in lib/providers.sh. Nothing else hardcodes a CLI name.
