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 | $0.00035 | $0.00206 |
| Opus 5 | $0.00017 | $0.00103 |
| Sonnet 5 | $0.00007 | $0.00041 |
| Haiku 4.5 | $0.00003 | $0.00021 |
Grade A, and why
superpowers-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 12d 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
Brainstorm Skill
When to use this skill
- before implementing non-trivial features
- before refactors with unclear scope
- before debugging complex issues
- before designing an automation workflow
Brainstorm template (use this exact structure)
Goal
- (1–2 sentences)
Constraints
- (tech stack, time, compatibility, performance, “must not change”, etc.)
Known context
- (what exists today; relevant files/components; current behavior)
Risks
- (security, data loss, regressions, surprising side effects)
Options (2–4)
For each option include:
- Summary
- Pros / cons
- Complexity / risk
Recommendation
- Pick one option and explain why
Acceptance criteria
- Bullet list of verifiable outcomes
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.

superpowers-brainstorm is a skill published in the GitHub repository anthonylee991/gemini-superpowers-antigravity (828 stars, last pushed 7mo ago), licensed MIT. It adds 35 tokens to every session and 206 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.
