brainstrust

name	brainstrust
description	Consult other leading AI models for a second opinion that is grounded in your actual codebase — the consulted model reads the repo itself (read/grep/find) instead of being hand-fed files. Use for code review, architecture, debugging, security, devil's advocate, strategy, exploring blind spots, or ideation/brainstorming. Routes Claude consults through a free Task subagent and non-Anthropic consults through the OpenRouter agent loop. Trigger with 'brains trust', 'second opinion', 'ask another model', 'peer review', 'consult', 'challenge this', 'devil's advocate', 'brainstorm with the panel'.

Brains Trust

Part of the shipwright method — see the shipwright skill for the work-loop this move fits into and when to invoke it.

Get a grounded second opinion from leading models. The defining move versus the old version: the consulted model is an agentic pair reviewer — it has read-only repo tools and explores the code itself, rather than reasoning over a bundle you hand-fed it. You point it at a few starting files; it follows the trail.

The one routing rule (read this first)

Who you consult decides the transport — and the cost:

Consulting…	Use	Cost
A Claude model (Opus/Sonnet/Haiku/Fable)	a Task subagent with an explore-and-critique prompt	free — rides the Claude Code subscription
A non-Anthropic model (Gemini / GPT / Qwen / DeepSeek …)	the OpenRouter agent harness (src/consult.ts)	paid OpenRouter tokens

A Claude subagent already has Read/Grep/Glob and an agent loop — it is an agentic pair reviewer out of the box, for free. So never pay the API to ask Claude. Pay only for the diverse voices — the whole value of a brains trust is different blind spots, and that means non-Claude models.

For an important call, a mixed panel is ideal: one free Claude subagent that reads the real files, plus one or two non-Anthropic voices via the harness.

Correlated blind spots: three Claude subagents "agreeing" is not three independent votes — they share Claude's blind spots. Same-provider panels too. For genuine diversity, span providers.

Methodologies (built-in recipes)

Each bundles a pattern + model count + a system-prompt lens. Pick by the kind of work:

Key	For	Pattern
review	correctness/security review of target code	consensus ×2
architecture	design trade-offs, simpler approaches	consensus ×2
debug	stuck after attempts → ranked root-cause hypotheses	consensus ×2
security	threat-model, ranked by exploitability × blast radius	consensus ×2
devils-advocate	argue hard AGAINST the current plan	single
strategy	product/approach decision	consensus ×2
explore	open: what are we missing? blind spots?	consensus ×2
ideate	DIVERGE — wide range of options, don't converge	consensus ×3

(ideate is brainstorming: same tools, different question — the model reads enough to ground ideas, then generates many distinct directions instead of narrowing.)

Setup — the harness needs its npm deps

src/consult.ts imports npm packages and node_modules is not committed. So before the first consult on a machine, install the deps: run npm install in this plugin's directory (idempotent — harmless to repeat, and a plugin update may need it again). Run the harness from that same directory so the deps and tsx resolve. If a consult ever errors with a missing module, that's the signal to install.

Running a non-Anthropic consult

Run from the plugin's directory:

export OPENROUTER_API_KEY=...        # Claude consults need no key
npx tsx src/consult.ts \
  --methodology review \
  --repo /path/to/repo \
  --question "Is the auth middleware order correct, and can a gated role reach /admin?" \
  --paths "src/server/index.ts:middleware registration; src/server/middleware/auth.ts:the gate"

--repo is the target repo to consult on (the harness reads files relative to it, so where you run from doesn't change which code the model sees).

• --methodology (default explore) picks the recipe. --pattern / --count / --models override it.
• --models is auto-chosen as flagship non-Anthropic, one per provider from the live list (models.flared.au), with a stale fallback if it's unreachable — or pass explicit ids (--models openai/gpt-5.4,google/gemini-3.1-pro-preview).
• --paths are hints (path:why, ;-separated), NOT limits — the model roams from there.
• --max-cost (default $0.50/model) and --max-steps (25) are hard ceilings via the agent loop's stopWhen. Each consult prints its own token cost.
• Output: each model's view to stdout (+ .brainstrust/<ts>-<methodology>/), with a total cost line.

Running a Claude consult (free)

Don't use the harness. Spawn a Task subagent: give it the question, the methodology lens (copy the relevant row's framing), and the starting file paths, and tell it to explore the repo and return a prioritised, file:line-cited critique. It reads the code natively. For consensus, spawn 2-3 with different stances (skeptic / pragmatist / security-hawk) in parallel.

The discipline (what keeps it honest)

• The panel is INPUT, not verdict. You synthesise: note where they agree/disagree, add your own read, and say plainly when you disagree with all of them. Don't defer to "the models said X" — they are often confidently wrong in chorus.
• Grounded only. The harness's system prompt forbids claims about code the model hasn't read and demands file:line citations. Hold consulted output to that — discount ungrounded assertions.
• Span providers for real diversity. Redundant providers give correlated errors.
• Mind the spend. Non-Claude consults cost money; Claude subagents don't. Run a panel for decisions that matter, not every edit.

When to use / not

Use: before a major architectural change; stuck debugging after 2+ attempts; security-sensitive code; challenging your own plan; ideation when you want breadth; any genuine "what are we missing?". Skip: simple syntax, well-known answers, every small edit (slow + costs money).
