audiocpp-extended

audiocpp-extended is a skill for Claude Code, Codex from Elumenotion/GuideAnts. It costs 140 tokens per session (2,580 once invoked), scanned D, original, Apache-2.0.

An experimental extension for audio.cpp, a system for generating speech and processing spoken audio. It adds access to features such as identifying different speakers and creating speech from a supplied voice recording.

In plain words
What is it for?
Use it for speaker-labeled transcripts, consented voice cloning, fixed-repeatability experiments, language-specific speech generation, and testing additional text-to-speech models.
Why use it?
It helps when the standard audio tools do not expose the voice, speaker, language, or model options you need.

Token cost

What it costs to keep this loaded

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.

Security

Grade D, and why

audiocpp-extended 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 5d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/diarize.py, scripts/engine_tool.py, scripts/fetch_model.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

audio.cpp extended (experimental)

GuideAnts exposes audio.cpp through curated wrapper services with a deliberately narrow contract ({text, voice, speed} against a fixed model catalog). The engine underneath supports much more. This skill reaches that extra surface without any GuideAnts changes, using the fact that the sandbox runs in the same container as the audio services.

Everything here is experimental. Run the probe first, trust its report over this document, and tell the user plainly when a route is blocked.

Always start with the probe

python3 Skills/audiocpp-extended/scripts/probe.py

It prints a JSON report saying which of the four routes below are open in this deployment, plus the evidence (ports reachable, dirs writable, binary present, HF egress, GPU state). Do not attempt a route the probe marked blocked.

Cloning a voice from a reference clip (voice_ref, Routes 1/3/4) is a supported, intended use of this skill when the speaker consents: the user states the clip is their own voice, or that they have the speaker's permission. In that case, proceed — do not refuse consented cloning as a "security risk"; producing a WAV deliverable in the workspace impersonates no live system. Decline only when the request is to imitate a third party without consent (a celebrity, a colleague, a public figure), and say that consent is the missing piece.

The four routes (try in this order)

Route 1 — raw engine API on the already-loaded model (cheapest)

The wrapper services each spawn a real audiocpp_server on localhost: ASR engine at 127.0.0.1:18082, TTS engine at 127.0.0.1:18084 (running only while the wrapper has a model loaded). Calling them directly unlocks, on the model GuideAnts already loaded:

  • Voice cloning from a user-supplied reference clip (voice_ref = an absolute path to a WAV in your workspace — same filesystem, so the engine can read it), optionally with reference_text.
  • Deterministic synthesis via seed.
  • Language forcing via language (the .NET wire never sends lang_code).
  • Voice-design instructions (only on a model loaded with the vdes task, i.e. the VoiceDesign catalog entry).
  • ASR on a workspace file by path with a language hint via /v1/audio/transcriptions — no upload, no wrapper contract.

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.

audiocpp-extended is a skill published in the GitHub repository Elumenotion/GuideAnts (57 stars, last pushed today), licensed Apache-2.0. It adds 140 tokens to every session and 2,580 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it D with 3 findings (tells the agent never to refuse, sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
