Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00017 | $0.01454 |
| Opus 5.5 | $0.00007 | $0.00582 |
| Sonnet 5.5 | $0.00003 | $0.00291 |
| Haiku 4.5 | $0.00002 | $0.00145 |
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 13d 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.
This is a copy
100% identical to brainstorm — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/brainstorm
If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md.
Brainstorm a product topic with a sharp, opinionated thinking partner. This is a conversation, not a deliverable — the goal is to push thinking further than the PM would get alone.

│ BRAINSTORM │
├────────────────────────────────────────────────────────────────┤
│ STANDALONE (always works) │
│ ✓ Explore problem spaces and opportunity areas │
│ ✓ Generate and challenge product ideas │

Workflow
1. Understand the Starting Point
The PM might bring any of these — identify which one and adapt:
- A problem: "Our users drop off during onboarding" — start in problem exploration mode
- A half-formed idea: "What if we added a marketplace?" — start in assumption testing mode
- A broad question: "How should we think about AI in our product?" — start in strategy exploration mode
- A constraint to work around: "We need to grow without adding headcount" — start in solution ideation mode
- A vague instinct: "Something feels off about our pricing" — start in problem exploration mode
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.
