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 | $0.00013 | $0.00288 |
| Opus 5 | $0.00006 | $0.00144 |
| Sonnet 5 | $0.00003 | $0.00058 |
| Haiku 4.5 | $0.00001 | $0.00029 |
Grade C, and why
build-voice-agent 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 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.

Instructions
- Fetch https://docs.cartesia.ai/line/start-building/quickstart.md and https://docs.cartesia.ai/llms.txt before writing code.
- Read the
cartesia-lineskill in this plugin (skills/cartesia-line/SKILL.md) and the references it links. - Do not invent
Cartesia-Version, Sonic/Ink model IDs, or CLI flags from memory. - Use the public CLI (
curl -fsSL https://cartesia.sh | sh),cartesia-line, andVoiceAgentApp. Cartesia runs Ink STT and Sonic TTS around the agent. - Include
end_call(or an equivalent) so the agent can hang up. - Use a fast conversational model (Haiku / Flash / mini class). Put slow reasoning behind background tools.
- After scaffolding: how to
cartesia init,cartesia deploy, andcartesia call.
Example usage
/build-voice-agent a dentist office that books appointments
/build-voice-agent customer support that can transfer to a human
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.
