What it does

Skill Creator is an agent skill from Aster110/mycc. 创建新的 Claude Code Skill。当用户说"帮我创建一个 skill"、"把这个变成 skill"、"新建技能"时触发。

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: MyCC - 让 Claude Code 跑在手机上 | Run Claude Code from your phone.

When your agent uses it

  • Tasks that involve Skill authoring

Example prompts

  • “帮我创建一个 skill”
  • “把这个变成 skill”
  • “/skill-creator”

Workflow steps

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

  1. 简洁为王
  2. 设置合适的自由度
  3. 渐进加载（三层）
  4. 理解需求
  5. 规划资源
  6. 创建目录
  7. 编写 SKILL.md
  8. 测试迭代

What it can do on your machine

Read from SKILL.md and the folder at commit 2925c64. 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 (its code samples are yaml and bash).

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

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    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

Skill Creator loads about 476 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 146 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~476

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 146 words (~476 tokens).
