What it does

Fetch Markdown Specs is an agent skill from tats-u/markdown-cjk-friendly. Read if you want to refer to the CommonMark/GFM specifications

Its SKILL.md is about 180 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 Documents & Office, covering Markdown. It works with GitHub. The repository describes itself as: Make CommonMark more friendly for Japanese/Chinese/Korean (CommonMark next specification draft)—plugins & patched packages. The licence is MIT.

When your agent uses it

  • Tasks that involve Markdown

Example prompts

  • “/fetch-markdown-specs”

What it can do on your machine

Read from SKILL.md and the folder at commit 41cb0ea. 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

    Shell commands in SKILL.md call:

    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, 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

Fetch Markdown Specs loads about 179 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 73 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
~179

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.

Since CommonMark and GFM specifications exist as files in GitHub repositories, you should fetch them by either:

  • get_file_contents in GitHub MCP Server
  • GitHub CLI (if its version is 2.95 or greater, you should use gh repo read-file <path> -R <owner>/<repo>)
FlavorRepositoryPath
CommonMarkcommonmark/commonmark-spec/spec.txt
GFMgithub/cmark-gfm/test/spec.txt

Standard fetchers like cURL lack authentication credentials and are more likely to hit rate limits, so we strongly recommend avoiding their use whenever possible.
