lms-front: Skill for Claude Code

.agents/skills/sound-setup/SKILL.md

sound-setup is a skill for Claude Code, Codex from guillermoscript/lms-front. It costs 68 tokens per session (1,309 once invoked), scanned C, original, MIT.

A setup wizard for choosing notification sounds played by Claude Code, the coding assistant. It lets you assign sounds to events such as completed turns, questions, errors, commits, and pushes, and preview the choices.

In plain words
What is it for?
Use it to select a sound pack, change sounds for specific events, mute or remap notifications, add text triggers, and test sounds before saving.
Why use it?
It removes the need to edit sound configuration files by hand. Changes are written to the sound hook's rules file and take effect immediately.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; names the AskUserQuestion tool; mentions Claude Code.

This is guillermoscript/lms-front's own configuration. It tells Claude Code and Codex how to work on lms-front itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything lms-front configures →

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 C, and why

sound-setup scanned grade C with 2 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

sound-setup

Walk the user through building their own sound mapping, previewing each choice out loud. Writes ~/.claude/hooks/sound-rules.json, which the hook re-reads on every event — changes apply immediately, no reinstall and no restart.

Before you start

Check the system is installed:

ls ~/.claude/hooks/status-sound.sh ~/.claude/hooks/sounds/ 2>/dev/null

If it isn't, install it first — the wizard has nothing to configure otherwise:

curl -fsSL https://raw.githubusercontent.com/guillermoscript/agent-skills/main/skills/claude-sounds/install.sh | bash -s -- --yes

That installer also places this skill, so a curl install gets /sound-setup with no extra step.

Then use TOOL=~/.claude/hooks/sound-tool.sh for every command below. If that file is missing, the user is on an older install — re-run the installer.

The events you can map

Event Fires when
done_tiny … done_epic A turn ended successfully, sized by lines written (<50, 50+, 200+, 500+, 1000+)
needs_input Claude ended with a question
failed / failed_big The turn hit an error
other Anything else
commit / push git commit / git push succeeded
pr_opened / pr_merged gh pr create / gh pr merge succeeded
tests_pass / tests_fail A test command finished
permission Claude is waiting for your approval

A slot is a sound file: ~/.claude/hooks/sounds/<slot>.mp3. Events map to slots, so several events can share one sound, and a pack swap changes the audio without touching the mapping.

How to run the wizard

Be conversational, not a form. Play sounds as you go — hearing it is the point. Never ask about all sixteen events; that's an interrogation, not a wizard.

1. Show them where they are

bash $TOOL list

Present it as a short table and ask what they want to change. If the user already said what they want ("zelda chest when a PR merges"), skip straight to doing it — don't make them sit through a menu.

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.
