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 | $0.00036 | $0.00571 |
| Opus 5.5 | $0.00014 | $0.00228 |
| Sonnet 5.5 | $0.00007 | $0.00114 |
| Haiku 4.5 | $0.00004 | $0.00057 |
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 1mo 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
/collaboration:brainstorming
Ported from obra/superpowers (MIT). Optimized for cortex so brainstorming outputs flow directly into Supersaiyan visuals and the Task TUI.
When to run
- Before touching code: align on problem, success signals, blockers.
- After big context shifts: new stakeholder, major dependency change, fresh repo checkout.
- When you feel stuck: broaden solution space before diving back in.
Inputs you need
- Current goal or ticket reference.
- Repo hints: relevant
modes/(e.g.,modes/Super_Saiyan.md) andscenarios/if they exist. - Constraints (deadline, platforms, regulatory, etc.).
Steps
- Set the stage
- Load
modes/Super_Saiyan.md(CTRL+P → "Super Saiyan Mode") for visual/tone context. - Skim any
scenarios/ideation/*.mdtied to the feature.
- Load
- Map the landscape
- List known goals, success metrics, blockers, unknowns.
- Capture existing assets (agents, rules, workflows) that might help.
- Generate options
- Expand at least three distinct approaches (different modes, agents, or workflows).
- Note pros/cons, risk, required verification per approach.
- Select candidate plan
- Pick the best approach and flag what still needs validation.
- Seed Tasks
- Open the Task view (
T) and add top-level tasks from the brainstorming takeaways (or run/ctx:plannext to formalize).
- Open the Task view (

What ships with it
1 file 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 NickCrew/Claude-Cortex (62 stars, last pushed 4mo ago), licensed MIT. It adds 36 tokens to every session and 571 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 2026-09-03.
