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 | $0.00067 | $0.02802 |
| Opus 5 | $0.00034 | $0.01401 |
| Sonnet 5 | $0.00013 | $0.00560 |
| Haiku 4.5 | $0.00007 | $0.00280 |
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 4d 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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Collaborative Brainstorming
Structured ideation using the Double Diamond model, grounded in persistent memory. Mined from 100+ real brainstorming sessions across production projects.
Core insight: AI excels at divergent phases (volume, cross-domain connections). Humans excel at convergent phases (judgment, selection). Separating the two, and using Sibyl to avoid re-exploring solved problems, is the shape that consistently produces useful brainstorms.
How to read this skill: the diamond is a rhythm, not a gate. Phases revisit when new information changes the frame, and most real brainstorms are Quick Mode. The table below picks the mode before any phase starts.
Reading the Brief
The brief tells you how wide to go. Read its signals before choosing a mode.
| Signal in the brief | Mode it selects |
|---|---|
| Stakes + uncertainty + an open question ("i'm terrified to announce...", "let's get weird!") | Go wide: exploration is the deliverable, not a plan |
| Crisp problem, known options | Quick mode; ceremony scales inversely with brief clarity |
| Risk or hardening framing ("get evil", "get gnarly") | Adversarial depth; generic-but-safe findings read as under-delivery |
| "Build it" / momentum words | Not a brainstorm: exit to implementation |
Phase 1: GROUND (Memory-First)
Lean on existing knowledge before generating new ideas. The cost of a Sibyl search is low; the cost of re-discovering a pattern we already learned is high.
Common moves
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 hyperb1iss/hyperskills (31 stars, last pushed 8d ago), licensed MIT. It adds 67 tokens to every session and 2,802 once invoked, about $0.0003 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.
