What it does
Trademark Assistant is an agent skill from cat-xierluo/legal-skills. 面向中国商标申请的类别规划、可注册性初筛及申请材料准备技能。基于尼斯分类（国际商标分类），引用中国法律法规。本技能应在接到商标咨询、需要结构化输出建议与风险分级、或需要准备申请材料时使用。不要用于：替代正式法律意见、承诺注册成功率、处理复杂商标争议案件。
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 114 other files, including scripts and reference files (for example `CHANGELOG.md`, `README.md` and `references/01-service-intake-checklist.md`).
It sits in Legal & Compliance, covering Intellectual property.
When your agent uses it
- Tasks that involve Intellectual property
Example prompts
- “/trademark-assistant”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- 申请主体与主营业务
- 拟申请商标（文字/图形/组合）
- 当前已知的目标类别或使用场景
What it can do on your machine
Read from SKILL.md and the folder at commit db2c58c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/, which the agent can run.
Shell commands in SKILL.md call:
uvpython3brew
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Trademark Assistant loads about 1.6k tokens when it runs, and up to ~452k if it reads all its reference files. Until then it costs about 37 tokens; SKILL.md has 308 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Its licence (CC-BY-NC-4.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 308 words (~1,641 tokens).
