At a glance

Move newly installed skills from '.agents/skills/' to the project's root 'skills/' directory, with options to rename and attribute them, and mark them as internal.

  • Works in 4 steps: Identify Target Skills & Options → Move/Rename to Internal → Update Frontmatter & Metadata → …

What it does

Internalize Skill is an agent skill from yamcodes/arkenv. Move newly installed skills from '.agents/skills/' to the project's root 'skills/' directory, with options to rename and attribute them, and mark them as internal. Use this skill whenever a new skill is installed and needs to be promoted, renamed, or attributed as a project-internal skill.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: ⛯ Typesafe environment variables with ArkType, Zod, or Valibot. The licence is MIT.

When your agent uses it

  • A new skill is installed and needs to be promoted
  • Attributed as a project-internal skill

Example prompts

  • “.agents/skills/”
  • “s root”
  • “/internalize-skill”

Workflow steps

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

  1. Identify Target Skills & Options
  2. Move/Rename to Internal
  3. Update Frontmatter & Metadata
  4. Append Markdown Credits (Optional)

What it can do on your machine

Read from SKILL.md and the folder at commit 74b3732. 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 bash and yaml).

    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

Internalize Skill loads about 750 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~750

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.

Internalize skill

This skill automates the process of moving externally installed skills to the project's internal skills/ directory, tagging them as internal, and optionally renaming and attributing them.

Workflow

  1. Identify Target Skills & Options:

    • Check the .agents/skills/ (or .agent/skills/) directory for subdirectories.
    • If the user explicitly named a skill (e.g., "internalize the research skill"), focus only on that one.
    • If the user was vague, clarify which skill to target.
    • Ask the user if they would like to:
      • Rename the skill (e.g., change creating-changesets to arkenv-changesets).
      • Add attribution details (e.g., original_author, original origin repository url).

  2. Move/Rename to Internal:

    • Move the identified skill directory to skills/<new-name> (where <new-name> defaults to the original name if no rename is requested).

  3. Update Frontmatter & Metadata:

    • Update the name field in the SKILL.md frontmatter to <new-name>.
    • Update the metadata block to include internal: true.
    • If attribution details were specified, add:
      • original_author: The original author's name.
      • origin: The URL or GitHub repository of the original skill.
      • author: The current maintainer or team name.

  4. Append Markdown Credits (Optional):

    • If the skill was renamed or customized, append a ## Credits or ## Acknowledgements section at the bottom of the skill's SKILL.md file linking back to the original source.

Implementation details

The skill should rely on standard bash commands for efficiency and portability.

Moving & renaming skills
bash
# If keeping the same name:
mv .agents/skills/<old-name> skills/

# If renaming:
mv .agents/skills/<old-name> skills/<new-name>
Updating metadata

Use code edits or awk to update SKILL.md frontmatter. The logic should:

  • Update name: <new-name> at the top.
  • Insert or merge the metadata block to ensure internal: true, plus any specified attribution fields.

Example of expected final frontmatter structure:

yaml
---
name: arkenv-changesets
description: Creates changesets for semantic versioning.
metadata:
  author: Yam Borodetsky
  original_author: Ollie Shop
  origin: github.com/ollieshop/creating-changesets
  version: 1.0.0
  internal: true
---

Safety checks

  • Ensure the root skills/ directory exists before moving.
  • Verify SKILL.md exists in the target directory before attempting to edit it.
  • Do not overwrite existing internal skills under skills/ unless explicitly confirmed by the user.
