# Quad Brainstorming Run independent ideation from up to four tracks and synthesize a decision-ready report: - **Claude track**: local `claude` CLI through stdin-based print mode. - **Codex track**: current Codex reasoning or native subagents when useful. - **Gemini track**: local `gemini` CLI through stdin-based headless mode when a safe no-tools/sandbox boundary is available. - **Forge track**: local ForgeCode `forge` CLI from a private temp directory, preferably a low-tool planning agent. Use this for explicitly requested multi-model exploration, architecture/product/design alternatives, risk discovery, and decision framing. This is not a code-review workflow; use `quad-review` for PR/diff defect review. If the chosen direction needs defect/PR review, run `quad-review` next. Keep the operation read-only. Do not edit files, create tickets, post comments, or contact external production systems unless the user explicitly changes the task. ## P0 Core Contract Every `quad-brainstorming` surface MUST preserve this contract. Future CLI, MCP, plugin, or GitHub Action surfaces may add convenience, but MUST NOT weaken consent, no-posting, no-raw-persistence, redaction, or read-only defaults. 1. **Provider/context disclosure**: before any external invocation, show selected context sources, redaction status, provider availability, auth/safety category, expected track count, persistence mode, and skipped-provider reasons. 2. **Read-only default**: no repository writes, ticket/PR
