Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

terminal-setup-install scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Then patch `~/.claude/settings.json` to wire up the hook. Use Python to read/write so JSON stays valid:

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 396 lines — stays where its author put it; the contents beside it link to each section on GitHub.

terminal-setup-install

When to auto-invoke

Auto-invoke when the user says any of:

  • "set up my terminal", "install ghostty", "install oh my zsh", "set up p10k"
  • "run the terminal setup guide", "install the meta-guide stack"
  • "I want clickable file paths in my terminal", "install the markdown preview kit"

When NOT to invoke

Do NOT invoke for:

  • Editing ~/.zshrc for unrelated reasons (use Edit directly)
  • Adding individual zsh plugins (use git clone + Edit)
  • Linux or Windows terminal setup (this is macOS-specific)
  • Already-installed full stacks where the user just wants to tweak one thing

What this skill does

If AskUserQuestion is unavailable (for example on OpenCode or Cowork), present the same extras choice as a plain-text lettered list and continue from the user's written answer instead of stopping.

  1. Preflight. Detects what's already installed and skips it.
  2. Core install in this exact order (sequential to avoid Homebrew portable-Ruby lock conflicts):
    1. Ghostty (cask)
    2. MesloLGS Nerd Font (cask)
    3. Glow (formula)
    4. Dracula theme for Ghostty (git clone)
    5. Ghostty config at ~/.config/ghostty/config
    6. Oh My Zsh (curl installer with RUNZSH=no KEEP_ZSHRC=no)
    7. Powerlevel10k theme (git clone into custom themes)
    8. zsh-autosuggestions + fast-syntax-highlighting plugins
  3. Restore .zshrc. OMZ overwrites ~/.zshrc; the skill copies user customisations from ~/.zshrc.pre-oh-my-zsh back into the new file (PATH exports, aliases, tool inits). SDKMAN goes at the very end.
  4. Set ZSH_THEME and plugins line:
    • ZSH_THEME="powerlevel10k/powerlevel10k"
    • plugins=(git brew macos zsh-autosuggestions fast-syntax-highlighting)
    • docker plugin only if docker is on PATH
  5. AskUserQuestion about optional markdown-preview extras (multi-select).
  6. Per-extra installs for each chosen option.
  7. Sanity tests. Run zsh -i -c checks for parse, claude alias (if present), tool inits.
  8. Hand off. Tell the user to open Ghostty (Spotlight) and run p10k configure interactively.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
