What is dotfiles CLAUDE.md?

Instructions for a public dotfiles repository managed with chezmoi, a tool that keeps configuration files synchronized across computers. They cover secret handling, Claude Code directories, and safe configuration updates.

Use them when changing the repository’s shell, Claude Code, or other machine-configuration files and when checking changes before applying them.

They help contributors avoid exposing private data or editing generated files in the wrong location.

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	$0.01833	$0.01833
Opus 5.5	$0.00733	$0.00733
Sonnet 5.5	$0.00367	$0.00367
Haiku 4.5	$0.00183	$0.00183

Security

Grade A, and why

dotfiles 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 2d 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.

CLAUDE.md

Chezmoi dotfiles repository with cross-platform development environment configuration.

⚠️ Public Repository

This repo is public (github.com/laurigates/dotfiles). Never commit private information: secrets/API tokens (use ~/.api_tokens, sourced by mise), personal hostnames/IPs, internal-only org facts, or machine-specific identifiers. Secret-adjacent files use the chezmoi private_ prefix and stay out of templates that render to tracked output. When in doubt, leave it out — assume anything committed is world-readable and indexed.

Work in a Worktree

Make changes to this repo in a Claude Code worktree, not in the main checkout — enter one before the first edit of a change task. Reading, answering questions, and running chezmoi diff/status do not need one.

Two mechanical reasons:

.claude/scripts/repos-sync-nudge.sh auto-fast-forwards this checkout only when git status --porcelain is empty. Uncommitted work in the main checkout silently switches that freshness auto-pull off — the exact thing the nudge exists to keep running.
worktree.baseRef is fresh, so a worktree branch starts from origin/main rather than from wherever this checkout happens to be sitting.

Inside a worktree, chezmoi needs --source. The source dir is pinned in ~/.config/chezmoi/chezmoi.toml and nothing in the environment overrides it — CHEZMOI_SOURCE_DIR and CHEZMOI_SOURCE are both ignored, only the flag takes effect. So a bare chezmoi apply from a worktree exits 0 having applied main's content instead of the edits in front of you, with no error and no empty result to notice. Use just apply / just diff / just status (or mise run apply), which pass --source "$(git rev-parse --show-toplevel)" for you; exact_dot_claude/hooks/executable_chezmoi-worktree-source-guard.sh warns when a bare one slips through.

From a worktree, apply named targets, never the whole tree. private_dot_config/chezmoi/chezmoi.toml.tmpl renders sourceDir = {{ .chezmoi.sourceDir | quote }}, and --source sets that value, so a full just apply (no target) from a worktree rewrites ~/.config/chezmoi/chezmoi.toml to point at the worktree. Every later bare chezmoi command then reads a worktree that is about to be removed. Test with just apply ~/.zshrc (named targets), and run the full apply from the main checkout after the merge. A sourceDir line in chezmoi --source "$PWD" diff ~/.config/chezmoi/chezmoi.toml is the tell.

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.
