These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.

Security

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 9d 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.

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

  1. Version Pinning: Always pin to immutable references (commit SHAs, specific versions, digests)
  2. Renovate Automation: Ensure all dependencies have corresponding Renovate rules
  3. Organization: Group externals by primary program using .chezmoiexternals/ directory
  4. Minimal Edits: Make focused changes without unrelated modifications
  5. 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 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.
