Code2patent

by cat-xierluo in cat-xierluo/legal-skills

从已开发代码项目中提取技术实现证据，围绕候选专利方案生成算法/软件类说明书式技术交底书，并以“权利要求布局卡 → 发明专利初稿”两步法继续生成接近可申报版的中国发明专利起草材料。触发场景包括：读取代码仓库后撰写技术交底书、将人工总结的专利方案映射到具体实现、从代码中挖掘可专利技术方案、为专利代理师准备权利要求布局和发明专利初稿。

What it does

Code2patent is an agent skill from cat-xierluo/legal-skills. 从已开发代码项目中提取技术实现证据，围绕候选专利方案生成算法/软件类说明书式技术交底书，并以“权利要求布局卡 → 发明专利初稿”两步法继续生成接近可申报版的中国发明专利起草材料。触发场景包括：读取代码仓库后撰写技术交底书、将人工总结的专利方案映射到具体实现、从代码中挖掘可专利技术方案、为专利代理师准备权利要求布局和发明专利初稿。

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 18 other files, including reference files (for example `CHANGELOG.md`, `README.md` and `references/algorithm-software-disclosure-format.md`).

It sits in Legal & Compliance.

When your agent uses it

  • Legal & Compliance work in your project

Example prompts

  • “权利要求布局卡 → 发明专利初稿”
  • “/code2patent”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. 是否已有候选专利方案清单。
  2. 候选清单是仅有名称，还是已有技术问题、核心实现、技术效果和代码范围。
  3. 本次目标是技术交底书、权利要求布局卡、发明专利初稿，还是候选方案挖掘。
  4. 是否有 PRD、需求说明、会议纪要、客户交底书模板、既有申请样式或代理师格式要求。
  5. 本次归档主题是什么，用于创建 archive/YYYY-MM-DD-主题/。

What it can do on your machine

Read from SKILL.md and the folder at commit c077fcc. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Code2patent loads about 1.4k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 295 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~12k

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); files beside SKILL.md are not scanned.

SKILL.md

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 295 words (~1,383 tokens).
