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 | $0.00300 | $0.00300 |
| Opus 5.5 | $0.00120 | $0.00120 |
| Sonnet 5.5 | $0.00060 | $0.00060 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
cursorrules 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
Metapowers
Structured, repeatable workflows for digital production domains. This project provides skills across 10 domains: Design, Research, Development, Marketing, Branding, Accessibility, Project Management, Coaching, Leadership, and Legal.
How to Use
Each domain has skills in plugins/<domain>/skills/<skill-name>/SKILL.md. Read the SKILL.md file for the domain you need and follow its process.
Key Domains
- Design — Design thinking: empathize → define → ideate → prototype → test
- Research — Double Diamond: discover → define → design → deliver
- Development — Plan → build → test → debug → review → ship
- Marketing — RACE: strategy → reach → act → convert → engage
- Branding — Discover → strategy → verbal → visual → guidelines + audit
- Accessibility — WCAG-EM: scope → evaluate → report → remediate → retest
- Coaching — Expert feedback: ux, code, copy, a11y, strategy
- Leadership — Assess → vision → build → develop → sustain + 7 tools
Artifacts
All outputs are stored in .metapowers/<domain>/<project>/ as numbered markdown files.
Skills Location
Skills are in plugins/<domain>/skills/<skill-name>/SKILL.md. Each contains structured instructions with prerequisites, process steps, and output format.
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.
