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

linkfox-google-patent-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 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/google_patent_search.py, scripts/onboarding.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill searches the public Google Patents database, returning matching patents with publication numbers, titles, inventors, assignees, dates, CPC classifications, and PDF links. Useful for cross-border sellers doing freedom-to-operate (FTO) checks, prior-art searches, and patent-infringement risk screening before listing a product.

Core Concepts

Google Patents Search runs a query (q) against the public Google Patents corpus. The query supports Google Patents' native advanced syntax (e.g. owner:"company", inventor:"name", date ranges). Results are returned as a ranked list of patents (and optionally Google Scholar articles).

This skill returns a list of patents with bibliographic fields. To retrieve detailed bibliographic data, full text, legal status, family, or images for a specific patent found here, feed the returned patentId/publicationNumber into the corresponding linkfox-zhihuiya-bibliography / linkfox-zhihuiya-legal-status / linkfox-zhihuiya-patent-family skills.

Changes

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.
