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 5.5 | $0.00037 | $0.01444 |
| Sonnet 5.5 | $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 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.
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.
