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 | $0.00158 | $0.03927 |
| Opus 5.5 | $0.00063 | $0.01571 |
| Sonnet 5.5 | $0.00032 | $0.00785 |
| Haiku 4.5 | $0.00016 | $0.00393 |
Grade A, and why
ai-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 16d 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 — 307 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ai-brainstorm — interrogate until shared understanding, then design
Two methods, one flow. Handshake interrogates the user until the idea is understood so completely it can be explained in 3rd-grader language, and captures it in a self-contained doc. Design gating (obra/superpowers) classifies how much process the request needs and puts a hard approval gate before any implementation. The union: understand first, classify second, approve before building, and leave a doc the next agent can run with.
Three paths (classify out loud before the first question)
Say the classification out loud — "this looks bounded, so I'll present a short design here rather than write a spec" — so your human partner can override it:
- Spike — a feasibility question ("can we...", "is it possible...", "quick and dirty is fine") whose output is an answer, not code you keep. Present the question and what you'll try in 2-3 sentences, get a nod, then find out as cheaply as correctness allows. No design doc. Report findings as a recommendation; anything built stays labeled throwaway.
- Bounded — a well-scoped change to a flow that already exists in this repo: a new flag, a small endpoint, a one-file fix. Bounded measures the REPO, not your familiarity. Ask the clarifying questions that matter, present a short design IN CHAT (a few sentences to a few short paragraphs), and STOP. Implementation starts only after your human partner says yes. No spec file.
- Architectural — new projects, new subsystems, changes that restructure how components fit together or alter interfaces others depend on. Full process: handshake questions, 2-3 approaches with trade-offs, sectioned design, written doc, self-review, user review, then planning.
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.

ai-brainstorm is a skill published in the GitHub repository arcasilesgroup/ai-engineering (61 stars, last pushed 2d ago), licensed Apache-2.0. It adds 158 tokens to every session and 3,927 once invoked, about $0.0006 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 2026-09-12.
