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

epo-patent-analyzer 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.

EPO Patent Analyzer Skill

Automated analysis of patent applications for European Patent Office compliance under the European Patent Convention (EPC).

When to Use

Invoke this skill when users ask to:

  • Review patent claims for EPO Art. 84 compliance
  • Check sufficiency of disclosure under Art. 83 EPC
  • Analyze EPO formalities under Rules 42-49 EPC
  • Convert USPTO-style claims to EPO two-part form
  • Prepare for EPO examination or respond to EPO communications
  • Validate applications before EP filing or Euro-PCT entry

What This Skill Does

Performs comprehensive EPO-focused analysis:

  1. Claims Analysis (Art. 84 EPC):

    • Clarity: identifies unclear or ambiguous terms
    • Conciseness: detects redundant or overlapping claims
    • Support: verifies all claims are supported by description
    • Two-part form (Rule 43(1) EPC): checks preamble + "characterised in that"
    • Claim categories: product, process, apparatus, use
    • Excluded subject matter: Art. 52(2) and Art. 53 EPC
  2. Sufficiency of Disclosure (Art. 83 EPC):

    • Reproducibility: can a person skilled in the art reproduce the invention?
    • Breadth of claims vs disclosure: is the full scope enabled?
    • Essential technical features: all present and described?
    • Working examples: at least one concrete embodiment?
  3. Formalities (Rules 42-49 EPC):

    • Description format (Rule 42): required sections in correct order
    • Claims form (Rule 43): two-part form, numbering, references
    • Drawings (Rule 46): margins, no text, reference signs
    • Abstract (Rule 47): max 150 words, figure designation
    • Physical requirements: A4, margins, fonts
  4. Issue Categorization:

    • Critical: Will cause objection under EPC
    • Important: May cause objection or limit scope
    • Minor: Best practice per EPO Guidelines

Required Data

This skill uses the EPO compliance analyzers and the EPC/EPO Guidelines search:
