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 | $0.00229 | $0.00229 |
| Opus 5.5 | $0.00092 | $0.00092 |
| Sonnet 5.5 | $0.00046 | $0.00046 |
| Haiku 4.5 | $0.00023 | $0.00023 |
Grade A, and why
ultimate-product-discovery-skill CLAUDE.md 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 2mo 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
Notes for agents working on this skill
Install commands are for Windows PowerShell
The maintainer runs Windows PowerShell 5.1, and so do many users of a published skill. Two things break there, both silently and both repeatedly:
- Use
npx.cmd, never barenpx. In PowerShellnpxresolves tonpx.ps1, which the default execution policy refuses to load —PSSecurityException / UnauthorizedAccess. The.cmdshim is not a PowerShell script, so it runs without touching the policy. Never suggest changing the execution policy to work around this; it weakens a security setting to save one character. - No
&&. PowerShell 5.1 has no&&operator. Give each command on its own line, or join with;if they genuinely must be one line.
So the shape to hand someone is:
npx.cmd -y skills@latest add <owner>/<repo>@<skill> -g -y
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.
