At a glance

A skill your agent uses when someone asks to level up their AIOS, close an audit gap, find what to automate next, or improve one workflow.

  • Works in 3 steps: Mindset interview (find the candidate) → Method interview (scope one) → Machine handoff (build it)
  • Someone asks to level up their AIOS
  • SKILL.md covers What this skill does, What /level-up is NOT, When /level-up runs and Inputs the skill reads, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Level Up is an agent skill from nateherkai/AIS-OS. Use when someone asks to level up their AIOS, close an audit gap, find what to automate next, or improve one workflow. Walks the 3Ms from choosing the constraint to shipping one useful artifact or verified repair.

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/3ms-framework.md`).

It sits in Agent Workflows. The repository describes itself as: AI Operating System starter kit for Claude Code and Codex. Five skills: /onboard, /audit, /link, /level-up, and /3d-brain. Includes the Three Ms framework.

When your agent uses it

  • Someone asks to level up their AIOS
  • Close an audit gap
  • Find what to automate next
  • Improve one workflow

Example prompts

  • “/level-up”

Workflow steps

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

  1. Mindset interview (find the candidate)
  2. Method interview (scope one)
  3. Machine handoff (build it)

What it can do on your machine

Read from SKILL.md and the folder at commit ce9cb93. 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 markdown).

    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

Level Up loads about 2.7k tokens when it runs, and up to ~6k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 1,471 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~2.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,471 words (~2,662 tokens).

“Walks the user through the 3Ms each week to surface and ship one new automation. One interview = one artifact. It also installs the 3Ms framework into the user's head over time — after 4-6 runs, the user starts spotting…”
