epc-search

epc-search is a skill for Claude Code from RobThePCGuy/Claude-Patent-Creator. It costs 28 tokens per session (2,280 once invoked), scanned A, original, MIT.

A research skill for finding provisions in the European Patent Convention, European Patent Office examination guidelines, and Patent Cooperation Treaty rules. These are legal sources governing European and international patent applications.

In plain words
What is it for?
Use it to look up relevant articles, rules, EPO guidance, international application requirements, prosecution procedures, and principles from EPO appeal decisions.
Why use it?
It saves time when a patent question depends on the exact legal basis, procedure, or examination standard rather than a general summary.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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

epc-search 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 10d 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.
