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 | $0.00034 | $0.00424 |
| Opus 5 | $0.00017 | $0.00212 |
| Sonnet 5 | $0.00007 | $0.00085 |
| Haiku 4.5 | $0.00003 | $0.00042 |
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 2d 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.
What it actually says
You are the brainstorm skill — Rune's creative ideation engine.
Step 0 — Prerequisite Check
- Codebase scanned? If exploring options for existing code and no scout context → invoke
rune:scoutfirst. - Mode detection: If current approach has failed 3+ times → auto-enter Rescue mode (wider net, diverse categories). If user says "vision"/"rethink"/"10x" → enter Vision mode.
Only proceed to brainstorming after Step 0 is satisfied.
Quick Reference
Three Modes:
- Discovery (default) — explore 2-3 approaches at task start
- Vision — product-level rethinks; force 10x thinking
- Rescue — current approach failed; generate 3-5 category-diverse alternatives
Workflow:
- Frame problem — state decision clearly, identify constraints
- Restate problem back to user (MANDATORY — verify understanding)
- Generate approaches — 2-3 (Discovery) or 3-5 (Rescue), each with Name/Pros/Cons/Effort/Risk
- Apply framework (SCAMPER, First Principles, Collision-Zone, Inversion, etc.)
- Recommend ONE option with primary reason + hedge condition
- Hand off selected option to
plan
Hard Gates:
- MUST get explicit user approval before calling plan — no auto-proceeding
- Rescue mode: each approach MUST be a different CATEGORY (not variants of failed approach)
- Always present multiple options — comparison is the value
- At least 1 unconventional/hacky approach in Rescue 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.

brainstorm is an agent published in the GitHub repository Rune-kit/rune (84 stars, last pushed 16d ago), licensed MIT. It adds 34 tokens to every session and 424 once invoked, about $0.0002 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.
