What is fork-and-customize?

A guide for copying this personal computer-setup project and adapting it for your own machines. It explains which package lists, configuration files, and dotfiles to replace.

Use it when creating your own version of the setup tool, changing supported packages, replacing shell or desktop settings, or preparing your fork for release.

It shows where personal settings live, so you can rebrand the project without rewriting its main code. Dotfiles are the configuration files that control tools such as your shell and desktop.

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 5.1	$0.00087	$0.01020
Opus 5	$0.00044	$0.00510
Sonnet 5	$0.00017	$0.00204
Haiku 4.5	$0.00009	$0.00102

Security

Grade A, and why

fork-and-customize 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 11d 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.

Forking personal-os-setup for your own setup

The repo is designed so most personalization lives in data (packages.yaml, the chezmoi source dir, docs/), not code — a fork mainly needs to replace those, not rewrite the app.

What to customize

Package catalog — src/personal_os_setup/config/packages.yaml. Structure: packages: <distro>: <manager>: <category>: [package names]. Edit/add/remove entries per distro; categories are free-form strings (they become Collapsible groups in the Packages tab). See [[add-system-action]] if you're also adding a brand-new manager backend, not just editing package lists for existing managers.
Dotfiles — src/personal_os_setup/config/chezmoi/ is the chezmoi source dir shipped with the package (chezmoi_source_dir() in tasks/system/chezmoi.py resolves it via importlib.resources). Replace dot_zshrc/dot_p10k.zsh/dot_config/... with your own, or use the app's own "Sync dotfiles" tab (chezmoi: track a new file action) to add files interactively once you're running your fork. .chezmoiexternal.toml/.chezmoiignore in that dir control externally-pulled resources (oh-my-zsh, plugins, theme) and ignore rules.
Branding / metadata:
- pyproject.toml: [project] name, description, [project.scripts] entry point name if you want a different CLI command.
- CNAME (repo root) — the custom domain for the docs site, only relevant if you're using GitHub Pages with a custom domain.
- src/personal_os_setup/tasks/system/help.py's DOCS_SITE_URL constant — the URL the in-app "🚀 Start" tab's doc-link buttons open. See app.py's _START_SECTION_NAME/_START_GUIDE_MARKDOWN if you also want to edit the in-app onboarding walkthrough text.
- properdocs.yml: site_name, site_author, theme.logo/favicon.
- README.md/docs/ content — the actual walkthrough docs the doc-link buttons point to.
OS-specific config under src/personal_os_setup/config/{darwin,unix,windows,others}/ — these are bundled app-specific config files (Raycast, Aerospace, GlazeWM, etc.) referenced by individual system actions in factory.py; swap for your own equivalents if you use different apps, and update the corresponding tasks/system/*.py action that references them.

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.
