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

prior-art-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 22d 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.

Prior Art Search Skill

Search existing patents and technical literature to identify prior art for novelty and patentability assessment.

Overview

This skill integrates with multiple MCP servers (Google Scholar, USPTO, Semantic Scholar) to conduct comprehensive prior art searches across patents, academic papers, and technical documentation.

Usage

The skill is typically invoked by the patent-landscape-analyst agent during the RESEARCH stage of the patent workflow.

Basic Usage Pattern

// The skill is invoked through agent orchestration
// Agent: patent-landscape-analyst
// Input: topic keywords, technical domain
// Output: aggregated landscape report

Input Parameters

Required

  • query: Search keywords and technical terms
    • Example: "homomorphic encryption privacy-preserving computation"

Optional

  • searchScope: Time range for results

    • Default: Last 5 years
    • Options: 1year, 3years, 5years, 10years, all
  • maxResultsPerSource: Maximum results from each source

    • Default: 5
    • Range: 1-20
  • sources: Which databases to query

    • Default: All enabled MCP servers
    • Options: google_scholar, uspto_patent, semantic_scholar, cnipa_patent, patsnap_search
  • jurisdiction: Filter by patent jurisdiction

    • Default: All jurisdictions
    • Options: CN, US, PCT
    • EP / JP are not supported (REQ-017): if the user asks for them, say so explicitly, then proceed without a jurisdiction filter (or suggest PCT for international filings). Never pass an unsupported code downstream.

Output Format

Primary Output

File: references/landscape_{topic_slug}.md

Contains aggregated search results organized by:

  • Patent references (with classification codes)
  • Academic literature
  • Technical standards
  • Industry implementations

Secondary Output

Files: references/{source}_{id}.md

Individual evidence cards for each finding:

  • Full citation
  • Abstract/summary
  • Relevance score
  • Key technical features
  • Novelty comparison notes
