brainstorm

brainstorm is a skill for Claude Code, Codex from cookys/autopilot. It costs 166 tokens per session (850 once invoked), scanned A, original, MIT.

A guided design discussion for situations where the solution options have not yet been worked out.

In plain words
What is it for?
Exploring an uncertain idea, asking focused questions, comparing two or three different designs, and agreeing on a direction before code is written.
Why use it?
It helps clarify the real problem, constraints, and possible approaches before implementation starts.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

brainstorm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

brainstorm — discover the design before any code exists

The discriminator vs neighbours: do the options exist yet?

  • No options yet / fuzzy needbrainstorm (this skill) — explore, then converge on a design.
  • Options on the table, need to decidethink-tank (multi-perspective) / think-tank-dialectic.
  • Need to know what others dosurvey (external research).
  • Approach already chosen → author the plan (references/plan-template.md) → dev-flow.

This is a gate: do NOT invoke any implementation skill or write code until the user approves a design.

Protocol

1. Explore the real need — Socratic, ONE question at a time

Don't propose solutions yet. Ask one focused question, wait for the answer, then ask the next. Surface the actual problem, the constraints, the success picture, the no-go zones. Stop asking once you can restate the need in one sentence the user confirms. (One-at-a-time matters: a wall of questions gets a thin answer; a single sharp question gets a real one.)

2. Surface 2–3 genuinely different approaches

Not strawmen. Each approach: a one-line essence, its honest tradeoffs, what it's best/worst at. They must differ in kind (different architecture / different mechanism), not just in parameter. If you can only find one real approach, say so — that's a finding, not a failure.

3. Converge to a design spec

Once the user leans toward an approach, write a short design spec: the chosen approach, why it beat the others (1 line each), the key decisions made, and the open questions that remain. Keep it tight — it's the thing the plan will be built from, not the plan itself.

4. The approval gate

Present the design spec and ask for explicit approval. Nothing downstream runs without it. On approval, hand off:

  • to references/plan-template.md to author the plan (then dev-flow to execute), or
  • directly to dev-flow if the work is small enough to skip a formal plan. On "not yet" → keep exploring (back to step 1/2) — do not force forward.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

brainstorm is a skill published in the GitHub repository cookys/autopilot (11 stars, last pushed 3d ago), licensed MIT. It adds 166 tokens to every session and 850 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
