What is patent-examine?

A skill for repeatedly reviewing and revising draft U.S. utility patent applications through simulated patent-examination discussions. It examines issues under the main U.S. patent-law requirements and prior-art review.

Use it to examine and revise a draft U.S. utility patent application and explore possible examiner objections.

It helps identify weaknesses in a patent draft before or during prosecution-style review. The input does not provide more specific capabilities.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00157	$0.03842
Opus 5.5	$0.00063	$0.01537
Sonnet 5.5	$0.00031	$0.00768
Haiku 4.5	$0.00016	$0.00384

Security

Grade A, and why

patent-examine 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/cycle_state.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.

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.
