Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00037 | $0.03780 |
| Opus 5.5 | $0.00015 | $0.01512 |
| Sonnet 5.5 | $0.00007 | $0.00756 |
| Haiku 4.5 | $0.00004 | $0.00378 |
Grade A, and why
brainstorming 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 21d 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 — 283 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brainstorming Ideas Into Designs
Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
Start by classifying how much process the request needs, then work through your path: understand the context, refine the idea, present a design, and get your human partner's approval.
Establish Shared Understanding
The outcome of brainstorming is an understanding your human partner can recognize and correct, grounded in what they want to accomplish.
- Discover intent. Use the request and available context to identify the intended outcome, who it is for, and what success looks like. When that information is missing, ask one focused question about purpose or intended use before proposing features or an approach. Knowing the app genre does not tell you why your partner wants it. Gathering missing requirements does not ask them to authorize the task again.
- Write back your understanding. Summarize the intended outcome, relevant constraints, and success criteria in a short note your partner can assess. Separate what they said from assumptions. Invite correction and incorporate their answer before treating this as the design brief.
- Carry intent into the design. Preserve the agreed understanding in the selected path's design artifact: the written spec for architectural work, or the in-chat design/probe for bounded work and spikes. Check proposed features and technical choices against that understanding.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

brainstorming is a skill published in the GitHub repository ForgeyClap/claude-forge (2 stars, last pushed 16d ago), licensed MIT. It adds 37 tokens to every session and 3,780 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-25.
