## Portable contract

- Apply the brainstorm contract with all four external providers: Gemini, Codex, Ollama, and Antigravity. The current host model forms its independent view first; unavailable providers are reported, not silently omitted; synthesis distinguishes verified evidence from inference.

## Host adapters

### Pi adapter

- Follow `/skill:brainstorm` semantics with `ask-multi` providers `gemini,codex,ollama,antigravity`, after the current Pi host model has committed its independent view.

### Claude Code adapter

The existing detailed workflow below is the Claude Code adapter. Its Agent, MCP, hook, `CLAUDE_PLUGIN_ROOT`, and `AskUserQuestion` mechanics apply only on Claude Code; they do not override the Pi adapter above.

# Multi-LLM Brainstorm (All Providers)

- Consult all available external LLM providers (Gemini, Codex, Ollama, Antigravity) simultaneously while Claude Opus performs its own independent research on the topic, then synthesize perspectives from all five participants.

+ Consult all available external LLM providers (Gemini, Codex, Grok, Ollama, Antigravity) simultaneously while Claude Opus performs its own independent research on the topic, then synthesize perspectives from all six participants.

## Instructions

1. Determine the brainstorm topic:

- If the user provided a topic directly, use it

- If the context is about code changes, gather the relevant diff with `git diff` and `git diff --cached`

- If the context is a design/plan, gather the relevant documentation or conversation context

2. If no topic is clear, ask the user what they'd like to brainstorm about.

- 3. Launch the `brainstorm-coordinator` agent with the topic, external providers set to `gemini,codex,ollama,antigravity`, and any gathered context. The coordinator will:

- Run its own Claude Opus research phase in parallel with the external dispatches (Phase 3B — reads actual files, traces code, uses WebFetch/WebSearch on referenced external docs)

- - Dispatch the topic to the four external providers in parallel (Phase 3A)

+ - Dispatch the topic to the five external providers in parallel (Phase 3A)

- Synthesize all findings with Claude's verified findings weighted higher than inferred ones
