A skill for preparing and checking a PCT international patent application. PCT is a filing process that lets an applicant seek patent protection across multiple countries through one initial application.

In plain words
What is it for?
Use it to prepare PCT forms, descriptions, claims, abstracts, drawings, and sequence listings; assess unity of invention; and plan later national or regional filings.
Why use it?
It provides a structured way to check required sections, invention unity, formal rules, national-phase planning, fees, and deadlines instead of handling each requirement from memory.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

pct-application 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 8d 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.
