What it does

Cc API Contract Safety is an agent skill from doccker/cc-use-exp. 前后端接口契约安全规范，适用于接口新增或调整、联调、列表分页异常与临时兼容治理；用于避免响应结构漂移被前端兼容长期掩盖。

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Backend & APIs, covering API design. The repository describes itself as: ⛔ No longer maintained → dev-agent-kit/recipes 让 Claude Code、Antigravity、Gemini CLI、Codex、Cursor 开箱即用的分层配置模板，总结十多年的日常开发经验.

When your agent uses it

  • Tasks that involve API design

Example prompts

  • “/cc-api-contract-safety”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. 成功响应包装
  2. 列表与分页结构
  3. 筛选项与枚举来源
  4. 字段映射与调用链
  5. 临时兼容治理
  6. 验证

What it can do on your machine

Read from SKILL.md and the folder at commit 64470cb. 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

Cc API Contract Safety loads about 349 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 70 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~349

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 (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 70 words (~349 tokens).
