patent-search-specialist

patent-search-specialist is an agent for Claude Code from RobThePCGuy/Claude-Patent-Creator. It costs 34 tokens per session (577 once invoked), scanned A, original, MIT.

An assistant for searching existing patents and assessing whether an invention may be new or usable without infringing other patents. It searches large patent databases and organizes the investigation into seven steps.

In plain words
What is it for?
Use it to define an invention, build search terms, search BigQuery, USPTO data, or a local collection, explore patent classification codes, and support patentability, freedom-to-operate, or technology-landscape research.
Why use it?
It reduces the manual work of finding relevant prior art, the earlier published ideas used to judge patent novelty, obviousness, and possible blocking rights.

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

patent-search-specialist 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 11d 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.

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.
