At a glance

A skill your agent uses when studying GitHub repositories for one-off analysis, reading source code, or fetching single files from GitHub.

  • Studying GitHub repositories for one-off analysis
  • SKILL.md covers When to Use, Mode 1: Full Repo Clone, Mode 2: Single File Fetch and Rules
  • Calls git and curl; reaches github.com and raw.githubusercontent.com
  • Reading source code

What it does

GitHub Fetch is an agent skill from archibate/dotfiles-opencode. Use this skill when studying GitHub repositories for one-off analysis, reading source code, or fetching single files from GitHub. TRIGGER when "study this repo", "install this repo", "read the README of X", "inspect source of X", "fetch file from GitHub", or any request to explore/analyze a GitHub project without making it a permanent workspace.

Its SKILL.md is about 470 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 Development. It works with GitHub. The repository describes itself as: Archibate's personal configuration for OpenCode.

When your agent uses it

  • Studying GitHub repositories for one-off analysis
  • Reading source code
  • Fetching single files from GitHub
  • Study this repo

Example prompts

  • “study this repo”
  • “install this repo”
  • “read the README of X”
  • “/github-fetch”

What it can do on your machine

Read from SKILL.md and the folder at commit 46b6b23. 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:

    • git
    • curl

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com
    • raw.githubusercontent.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

GitHub Fetch loads about 472 tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 173 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~472

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 173 words (~472 tokens).
