Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00093 | $0.03609 |
| Opus 5 | $0.00046 | $0.01804 |
| Sonnet 5 | $0.00019 | $0.00722 |
| Haiku 4.5 | $0.00009 | $0.00361 |
Grade A, and why
voice-line scanned grade A with 0 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 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to voice-line — 114 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

/voice-line — Generate TTS Voice for NPCs, Narrator, Dialogue
Overview
The hardest part of TTS isn't the line — it's picking the right voice. ElevenLabs ships hundreds; pick wrong and a tough warlord NPC sounds like a podcast host. This skill walks the voice-id discovery flow (onyx_list_models family audio-voice), narrows by gender / accent / age / energy, presents 4–5 finalists with sample URLs for the user to audition, and locks the pick before generating.
Then it generates one line (or a multi-turn dialogue) with the right stability / style / similarity / speed for the delivery — flat for narration, expressive for a bark, fast for an excited shout.
When to use
- NPC bark, narrator line, dialogue between two characters, tutorial voice, menu announcer.
- Multi-line conversation with two or more voices → use
text_to_dialoguecapability.
When NOT to use
- Non-verbal vocal SFX (grunt, scream) →
audio/sound-effectwith promptmale grunt of pain, mid-thirties, sharp, 400ms. - Pre-recorded voice from a real actor — import the .mp3 / .wav with
onyx_import_from_urland skip TTS.
Steps
1. Read the audio bible and any character notes
Read .onyx/audio-bible.md
Read .onyx/memory/casting/voices.md # preferred cast memory, if present
Read .onyx/voice-cast.md # legacy cast memory, if present
Read .onyx/characters.md # if present
Glob .onyx/characters/*.md
Glob .onyx/memory/characters/*.md
If a character bible exists, the voice should match the character's age / gender / regional origin / energy. If it doesn't, ask:
Tell me the character: gender, rough age, accent or regional flavor, and energy (calm / measured / excited / gruff). Or just give me a reference — "sounds like the captain in Mass Effect" works.
2. Browse the voice catalog
onyx_list_models(family="audio-voice")
Returns a list with id, name, accent, gender, age, description, and previewUrl. Filter mentally to 8–12 candidates by the character's hard constraints (gender + age + accent), then pick 4–5 finalists with maximally distinct character (gruff vs warm vs neutral vs theatrical).
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.

Other skills, from other repositories
seedance-audio
This skill should be used when the user asks for Seedance 2.0 audio, dialogue, lip-sync, music, sound effects, ambience, beat-sync, audio-reference mapping, desync troubleshooting, or sound-driven visual timing.
listen
Nested swiss-knife reference for local audio analysis — transcribe speech with Whisper, or extract musical features (tempo, key, dynamics, spectral profile) with librosa. Both run on the user's machine with no API key. Read this when the human asks you to transcribe a voice note, extract lyrics from singing, critique…
metasounds
Create and modify MetaSound Source assets — add/connect nodes, wire pins, set input defaults, and play procedurally (MetaSoundService). Use when the user asks to create a MetaSound, build or edit a MetaSound graph, add operator/input/output nodes, or generate procedural audio.
videoagent-audio-studio
Tired of juggling multiple audio APIs? This skill gives you one-command access to TTS, music generation, sound effects, and voice cloning. Use when you want to generate any audio without managing multiple API keys.
multimodal-llm
Vision, audio, video generation, and multimodal LLM integration patterns. Use when processing images, transcribing audio, generating speech, generating AI video (Kling v3, Sora 2, Veo 3.1 std/lite/fast, Runway Gen-4.5 via gen4turbo), or building multimodal AI pipelines.
transcribe-tool
Audio transcription tool. Converts audio files to text with Whisper and optional LLM post-processing. Use when: transcribing meetings, podcasts, or extracting text from recorded audio files.
