What it does

Dev Env Setup is an agent skill from nateberkopec/dotfiles. Set up or audit Nate's standard dev environment in a project directory. Use for mise tasks, hk hooks, CI hardening, or standardized project tooling.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. The skill folder holds 28 other files, including scripts and reference files (for example `references/hk-hooks.md`, `references/mise-and-hooks.md` and `references/project-commands.md`).

It sits in Development. It works with Git and Ruby. The repository describes itself as: yup we're doin the thing.

When your agent uses it

  • Standardized project tooling

Example prompts

  • “/dev-env-setup”

Workflow steps

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

  1. Establish ownership and a clean Git baseline.
  2. Run the checker and inspect the project’s existing toolchain.
  3. Load only the applicable references and make the smallest changes that satisfy failures.
  4. Run dependency preparation, then every standard task directly.
  5. Run the checker again.
  6. Confirm git status is clean for foreign repositories; for owned repositories, account for every intended tracked change.

What it can do on your machine

Read from SKILL.md and the folder at commit dbfc96a. 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

    Ships 11 files in scripts/, which the agent can run.

    Shell commands in SKILL.md call:

    • git

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

  • Network

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

Dev Env Setup loads about 671 tokens when it runs, and up to ~4.8k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~671
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.8k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:20
    fnox/1Password runtime references. Keep `.env` untracked and examples fake. GitHub Actions must pin third-party actions

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); the scripts in this folder are not scanned.

Without a licence we can't republish the file, so here is its outline and opening line. It has 289 words (~671 tokens).
