trademark-assistant

trademark-assistant is a skill for Claude Code, Codex from cat-xierluo/legal-skills. It costs 91 tokens per session (3,540 once invoked), scanned A, original, no licence file.

A tool for planning Chinese trademark applications, doing an initial registrability check, and preparing application materials using the international Nice Classification. It refers to Chinese laws and regulations but is not formal legal advice.

In plain words
What is it for?
Use it for Chinese trademark consultations, category planning, structured risk assessments, and draft application materials. It is not for guaranteeing registration or handling complex disputes.
Why use it?
Choosing the right trademark categories and spotting obvious risks can be difficult before applying. This helps organise the preliminary work and identify issues that may need legal review.

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

trademark-assistant 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 1mo 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.

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.
