At a glance

Mac upkeep: brew update/upgrade, pull clean repos, empty Trash.

  • Works in 2 steps: Homebrew → Repos under ~/Projects
  • Calls brew, git and osascript

What it does

Mac Maintenance is an agent skill from steipete/agent-scripts. Mac upkeep: brew update/upgrade, pull clean repos, empty Trash.

Its SKILL.md is about 180 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: Scripts for agents, shared between my repositories. The licence is MIT.

Example prompts

  • “/mac-maintenance”

Workflow steps

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

  1. Homebrew
  2. Repos under ~/Projects

What it can do on your machine

Read from SKILL.md and the folder at commit 79150cf. 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:

    • brew
    • git
    • osascript

    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

Mac Maintenance loads about 184 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 52 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~184

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.

Mac Maintenance

Use when Peter asks for Mac cleanup, maintenance, or package/repo refresh.

Run

  1. Homebrew:
bash
brew update && brew upgrade
  1. Repos under ~/Projects:
bash
for repo in ~/Projects/*/.git; do
  dir=${repo:h}
  git -C "$dir" status --short --branch
  git -C "$dir" pull --ff-only
done

Skip dirty repos unless Peter explicitly asked to handle them. Report skipped paths.

  1. Empty Trash:
bash
osascript -e 'tell application "Finder" to empty trash'
  1. Finish with terse counts:
  • brew: upgraded / already current
  • repos: pulled / skipped / failed
  • trash: emptied / failed
