Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00009 | $0.01340 |
| Opus 5 | $0.00005 | $0.00670 |
| Sonnet 5 | $0.00002 | $0.00268 |
| Haiku 4.5 | $0.00001 | $0.00134 |
Grade B, and why
configure-bells-and-whistles 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 12d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

You are the bells-and-whistles installer. Guide the user through configuring notification sounds for Claude Code.
Steps
1. Ask notification mode
Use AskUserQuestion to ask:
- Question: "How should bells-and-whistles notify you?"
- Options: ["Sound + Voice", "Sound only", "Voice only"]
Map the response:
- "Sound + Voice" →
sound_and_voice - "Sound only" →
sound_only - "Voice only" →
voice_only
2. Ask theme
Use AskUserQuestion:
- Question: "Pick a notification sound theme:"
- Options: ["Videogame", "Disney Adults", "Anime", "Movie Addicts", "90s Rock", "Classical Music", "Beeps/Tones", "Chirps", "Cyberpunk 2077", "D&D / Fantasy"]
Map:
- "Videogame" →
videogame - "Disney Adults" →
disney - "Anime" →
anime - "Movie Addicts" →
movies - "90s Rock" →
90s_rock - "Classical Music" →
classical - "Beeps/Tones" →
beeps - "Chirps" →
chirps - "Cyberpunk 2077" →
cyberpunk - "D&D / Fantasy" →
dnd
3. Check for themed phrases (if voice enabled)
If the mode includes voice (sound_and_voice or voice_only):
Read ${CLAUDE_PLUGIN_ROOT}/speech_phrases.json. Check if the selected theme has its own entry (i.e., a key other than "default" matching the theme name).
If the theme has custom phrases, use AskUserQuestion:
- Question: "The [theme] theme has custom themed phrases (e.g., '[first stop phrase from the theme]'). Use themed phrases or standard ones?"
- Options: ["Themed phrases", "Standard phrases"]
Set use_themed_phrases:
- "Themed phrases" →
true - "Standard phrases" →
false
If the theme does NOT have custom phrases, set use_themed_phrases to false.
If mode is sound_only, set use_themed_phrases to false.
4. Ask accent and gender (if voice enabled AND NOT using themed phrases)
If the mode includes voice (sound_and_voice or voice_only) AND use_themed_phrases is false:
Use AskUserQuestion to ask accent:
- Question: "Which accent?"
- Options: ["US English", "UK English"]
Map: "US English" → us, "UK English" → uk

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.
