What is setmac CLAUDE.md?

Repository instructions for setmac, a macOS app and command-line tool that reinstall development tools, applications, and configuration after a computer reset.

Use them when working on setmac's SwiftUI interface, Python command-line backend, shared tool manifest, installation logic, or live status reporting.

They give an AI agent the project's structure, technology choices, commands, and conventions needed to make safe, consistent changes.

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.

Model	Per session	Once invoked
Fable 5	$0.01414	$0.01414
Opus 5	$0.00707	$0.00707
Sonnet 5	$0.00283	$0.00283
Haiku 4.5	$0.00141	$0.00141

Security

Grade A, and why

setmac CLAUDE.md scanned grade A with 0 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

setmac

macOS developer environment installer — automates reinstalling all dev tools, apps, and configs after a fresh format.

Architecture

SwiftUI macOS app (SPM, macOS 26+) — native sidebar UI, streams live status/logs
Python CLI backend (uv + click) — does all actual installing via subprocess
Shared Resources/tools.json manifest — single source of truth for both GUI and CLI
SwiftUI spawns CLI via Process, reads JSON-line stdout, updates UI in real-time

Key Commands

Uses just (not make) as the command runner.

just dev               # Clean build + run with live os.log streaming
just build             # swift build (incremental)
just release           # swift build -c release
just bundle            # .app bundle with embedded CLI + configs
just status            # CLI: check all tool statuses
just capture-configs   # CLI: snapshot current dotfiles
just                   # List all available recipes

Critical Conventions

CLI binary naming

The bundled CLI binary is named setmac-cli (NOT setmac) to avoid case-insensitive APFS collision with the GUI binary Setmac. This applies to:

CLIBridge.swift — looks for setmac-cli
scripts/build-cli.sh — PyInstaller outputs setmac-cli
scripts/bundle.sh — copies setmac-cli into .app bundle

What this file has done since we first saw it

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.
