Working in this repo #

This is a chezmoi source directory for public dotfiles. Read README.md for the layout. These rules cover what isn't obvious from the files.

The repo is public #

Internal names (work hosts, org names, vault and item names, work emails, internal tool names) only go in encrypted files. That includes comments and commit messages.

Before any push, search unencrypted tracked files and the unpushed history:

git ls-files | grep -v '\.age$' | xargs grep -niE '<internal terms>'
git --no-pager log -p --no-ext-diff origin/main..HEAD -- . ':(exclude)*.age'

Never add a global Host github.com rule, and never change which key the agent offers by default. The work identity must stay the default: private Go modules clone from Go's module cache, outside any folder rule, and a different default breaks them.
Per-identity behavior lives in folder-based Match exec rules in the encrypted ~/.ssh/config.d/work. Extend those instead.
The dotfiles remote uses SSH. Don't switch it to HTTPS: gh supplies the token there, and its active account is the work one.
Check an identity with ssh -T git@github.com from the folder in question.

git.autoCommit = true: chezmoi add, forget and similar commands commit everything pending in the source directory. Commit or ask about pending work first.
chezmoi prompts before overwriting a file that changed since its last write. The prompt needs a TTY and fails here. Diff the file, keep anything the user added (copy it into the source first), and only then use --force.
Files in the repo root (README.md, CLAUDE.md, the Brewfiles) must stay in .chezmoiignore, or chezmoi deploys them to ~.
Work-only targets belong in the else branch of .chezmoiignore.
chezmoi edit opens an interactive editor and won't work here. For encrypted files: chezmoi decrypt < file.age > tmp, edit, then chezmoi encrypt < tmp > file.age. Keep the .tmpl.age suffix for encrypted templates.
Templates use missingkey=error; a new data key needs a value on every machine ("" or false when it doesn't apply).

Render templates for both machine types with scratch configs instead of the real one: write a config with is_work = true and one with false, then chezmoi --config <scratch> execute-template < file.tmpl or chezmoi --config <scratch> cat ~/target.
chezmoi --config <scratch> managed shows which targets a machine type gets.
brew-drift needs fzf and a TTY. Test it with fish --no-config (so the user's fish config doesn't reorder PATH) and a stand-in fzf script that prints scripted selections.

Each op call costs the user a biometric approval. Never run op to explore. Templates that call onepasswordRead cost one approval per chezmoi diff/status/apply on machines that render them.
The age key fetch script runs op read only when the key file is missing.

brew bundle dump prints the installed set in Brewfile form, with options such as trusted: true and custom tap URLs. Copy entries from it rather than writing them by hand or with brew bundle add, which drops options.
brew bundle remove --formula fails for formulae that no longer exist, and without --formula it leaves the description comment behind. brew-drift edits the text directly for that reason.
