What it does

Skill Installer is an agent skill from codewhale-hq/Codewhale. Install, update, trust, or inspect Codewhale skills from GitHub or local skill folders. Use when the user asks for available skills or wants a community skill installed.

Its SKILL.md is about 360 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 management. It works with GitHub. The repository describes itself as: Open-source coding agent for your terminal, built in Rust and on a journey of continuous community improvement. Issues and PRs welcome. The licence is MIT.

When your agent uses it

  • The user asks for available skills
  • Wants a community skill installed

Example prompts

  • “/skill-installer”

Workflow steps

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

  1. Identify the source
  2. Prefer Codewhale's native /skill commands over ad hoc copying.
  3. For GitHub/community skills, inspect the SKILL.md before recommending
  4. After installing, tell the user to restart the session if the skill does not
  5. If a skill conflicts by name with a workspace skill, explain that workspace

What it can do on your machine

Read from SKILL.md and the folder at commit fead51e. 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

Skill Installer loads about 360 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 174 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~360

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 Installer

Use this skill when the user wants to find, install, update, trust, or remove a Codewhale skill.

Commands

  • List installed skills: /skills
  • Activate a skill: /skill <name>
  • Scaffold a new skill: /skill new
  • Install from GitHub: /skill install github:<owner>/<repo>
  • Update installed skills: /skill update
  • Remove a skill: /skill uninstall <name>
  • Trust a skill for script/tool use: /skill trust <name>

Workflow

  1. Identify the source:
    • Existing local folder with SKILL.md
    • GitHub repo or registry entry
    • User request for a new skill scaffold
  2. Prefer Codewhale's native /skill commands over ad hoc copying.
  3. For GitHub/community skills, inspect the SKILL.md before recommending trust. Treat scripts and companion files as untrusted until reviewed.
  4. After installing, tell the user to restart the session if the skill does not appear immediately in the available-skills list.
  5. If a skill conflicts by name with a workspace skill, explain that workspace skill directories take precedence over global ~/.codewhale/skills, with

Do not execute community skill scripts unless the user explicitly asks and the skill has been reviewed or trusted.
