personal-os-setup: Skill for Claude Code

.claude/skills/chezmoi-scripts/SKILL.md

chezmoi-scripts is a skill for Claude Code from AmineDjeghri/personal-os-setup. It costs 109 tokens per session (2,646 once invoked), scanned B, original, MIT.

A guide to scripts managed by chezmoi, a tool that keeps computer configuration files in sync. It explains when those scripts run during a selected-file sync.

In plain words
What is it for?
Use it to add or debug scripts that run once, after every change, or when a configuration file changes, including scripts for Hyprland or Noctalia.
Why use it?
It explains why a script may not run when a nearby configuration file is selected: the script itself must be included in the targeted sync. This helps diagnose seemingly ignored setup actions.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 B, and why

chezmoi-scripts scanned grade B 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 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.

chezmoi script scoping in personal-os-setup

Verified directly against a real chezmoi binary (v2.72.0), not assumed from docs — see the exact commands below if you want to reproduce.

The core gotcha: a targeted chezmoi apply does not run sibling scripts

The "Sync dotfiles" tab's apply selected/diff selected/etc. buttons never run a bare chezmoi applychezmoi_apply() in tasks/system/chezmoi.py always passes the selected paths as explicit targets: chezmoi apply --force --parent-dirs <target1> <target2> .... A run_/run_once_/run_onchange_ script only executes if its own managed path is included in that target list — being in the same directory as a targeted file is not enough:

  • chezmoi apply <only .zshrc> → noctalia/hypr untouched, scripts don't run.
  • chezmoi apply <only noctalia/config.toml> (a sibling file in the same dir as the script) → the script still does not run, even though it's in the same folder.
  • chezmoi apply <the script's own managed path> → script runs.

Reproduce this yourself with a scratch source dir if you need to double-check chezmoi's current behavior before relying on it:

mkdir -p /tmp/t/{home,src/dot_config/x} && cd /tmp/t
echo x > src/dot_config/x/file.txt
printf '#!/bin/bash\necho RAN\n' > src/dot_config/x/run_after_thing.sh
HOME=$PWD/home chezmoi --source $PWD/src apply -v --force --parent-dirs $PWD/home/.config/x/file.txt
# "RAN" does not print -- the script's own path wasn't a target.

Why this matters for the frontend's dotfiles tree

chezmoi_managed_paths() (tasks/system/chezmoi.py) calls chezmoi managed --include=files,scripts,symlinksscripts show up as their own selectable leaf entries in the tree (app.py's Tree[DotfileTreeNode]), separate from the config files they live next to. Tree-node selection (on_tree_node_selecteddata.all_file_paths()) selects every leaf under whichever node you click:

  • Select only noctalia/config.toml and click apply selected → the config applies, but run_after_ensure-noctalia-running.sh.tmpl (a sibling leaf) does not fire.
  • Select the whole noctalia folder → the script leaf is included too, so it fires.
  • Same rule for run_after_check-hyprland-plugins.sh.tmpl under hypr.

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.

chezmoi-scripts is a skill published in the GitHub repository AmineDjeghri/personal-os-setup (602 stars, last pushed yesterday), licensed MIT. It adds 109 tokens to every session and 2,646 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
