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 | $0.00094 | $0.02063 |
| Opus 5.5 | $0.00038 | $0.00825 |
| Sonnet 5.5 | $0.00019 | $0.00413 |
| Haiku 4.5 | $0.00009 | $0.00206 |
Grade D, and why
claude-sounds scanned grade D with 3 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -fsSL https://raw.githubusercontent.com/guillermoscript/agent-skills/main/skills/claude-sounds/install.sh | bash How it starts
The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
claude-sounds — hear what just happened
Ambient awareness for long runs. Walk away from the terminal and still know whether it landed, died, or is waiting on you — and, for turn endings, roughly how big the change was.
Install
curl -fsSL https://raw.githubusercontent.com/guillermoscript/agent-skills/main/skills/claude-sounds/install.sh | bash
Pick a pack while installing:
curl -fsSL .../install.sh | bash -s -- --pack zelda
Then restart Claude Code, or open /hooks once — the settings watcher does
not pick up a new hook mid-session. This is the most common reason it seems not
to work.
Requires jq, curl, and an audio player (afplay ships with macOS; mpv,
ffplay, mpg123 or paplay on Linux).
The installer also drops the /sound-setup wizard into
~/.claude/skills/sound-setup/, so customizing works straight after a curl
install with no extra step.
Flags: --pack <name>, --uninstall, --no-sounds (hook only, spoken
fallbacks), --no-git (turn-end sounds only), --no-skill (skip the wizard),
--dry-run, --yes.
What plays when
When a turn ends, scaled by lines written or edited in that turn (Write
content + Edit new_string, counted only since the last user prompt):
| Lines | Event | tiktok | zelda | mario |
|---|---|---|---|---|
| <50 | done_tiny |
vine boom | rupee | coin |
| 50+ | done_small |
FAAAH | korok | 1-up |
| 200+ | done_medium |
Faaaa | secret jingle | 1-up mushroom |
| 500+ | done_big |
boosted FAAAH | item catch | extra life |
| 1000+ | done_epic |
I GOT THIS FAAAAAHHHH | high-value item | course clear |
Status comes from the last assistant message. The three background-job markers are exact; the rest is a heuristic.
| Trigger | Event |
|---|---|
contains result: |
completed → one of the five above |
contains needs input:, or ends with ? |
needs_input |
contains failed:, or error keywords |
failed (failed_big over 200 lines) |
| anything else | other |
What ships with it
8 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.

claude-sounds is a skill published in the GitHub repository guillermoscript/lms-front (40 stars, last pushed today), licensed MIT. It adds 94 tokens to every session and 2,063 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it D with 3 findings (downloads and executes remote code, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
