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 | $0.00088 | $0.03027 |
| Opus 5.5 | $0.00035 | $0.01211 |
| Sonnet 5.5 | $0.00018 | $0.00605 |
| Haiku 4.5 | $0.00009 | $0.00303 |
Grade A, and why
managing-chezmoi-packages scanned grade A with 1 finding 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 8d 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.

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

Managing Chezmoi Packages
This skill handles all aspects of package and dependency management in chezmoi dotfiles repositories, with emphasis on security, reproducibility, and automated updates.
Core Principles
- Version Pinning: Always pin to immutable references (commit SHAs, specific versions, digests)
- Renovate Automation: Ensure all dependencies have corresponding Renovate rules
- Organization: Group externals by primary program using
.chezmoiexternals/directory - Minimal Edits: Make focused changes without unrelated modifications
- Preview First: Show proposed changes before applying
When to Use This Skill
Invoke this skill when the user requests:
- Adding/updating/removing packages or tools
- Managing chezmoi external dependencies
- Pinning versions or updating SHAs
- Organizing external files by program
- Setting up Renovate automation for dependencies
- Choosing between package ecosystems (Homebrew, mise, etc.)
Workflow
1. Identify the Request
Determine what the user wants:
- Add: New package or external dependency
- Update: Change version/SHA of existing package
- Remove: Delete package or external
- Organize: Migrate externals to
.chezmoiexternals/structure - Pin: Add immutable version/SHA reference
2. Select the Ecosystem
Choose the appropriate package manager (see ./ecosystem-guide.md for details):
| Use Case | Ecosystem | Location |
|---|---|---|
| macOS packages (Homebrew) | brew/cask/mas | home/.chezmoidata/packages.yaml |
| CLI developer tools | mise (Aqua) | .mise.toml or home/dot_config/mise/config.toml |
| Python tools | pip | home/dot_config/dotfiles/requirements.txt |
| Docker/devcontainer | docker | home/dot_config/docker-compose/*.yml, .devcontainer/ |
| External files/repos | chezmoi externals | home/.chezmoiexternals/*.toml[.tmpl] |
| Install script CLIs | cli-versions | home/dot_config/dotfiles/cli-versions.toml |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

managing-chezmoi-packages is a skill published in the GitHub repository martinemde/dotfiles (10 stars, last pushed yesterday), licensed ISC. It adds 88 tokens to every session and 3,027 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 88% identical to managing-chezmoi-packages, differing in 30 lines, and is treated as a copy.
Other skills, from other repositories
dotfiles-bootstrap
Bootstrap a workstation with the dotfiles framework. Takes a GitHub user / owner+repo / explicit clone URL and runs dot config init (which shells out to chezmoi) with the right safety prompts. Honors the active agent profile (ask / plan / apply / audit) so it defaults to dry-run in safer modes and full apply in apply.
vibe
Delegate a coding task to a cheap AI model (Mistral Vibe by default, but any provider Vibe knows about — DeepSeek, Gemini Flash, etc.) and supervise the result via git diff. Claude orchestrates, the cheap model codes. Claude consumes 500-1500 tokens per delegation regardless of how many file reads the delegate does…
