text-to-speech

text-to-speech is a skill for Claude Code from eins78/agent-skills. It costs 85 tokens per session (2,839 once invoked), scanned A, original, MIT.

A local text-to-speech pipeline that turns a text document into an MP3 audio file. Text-to-speech means generating spoken audio from written words.

In plain words
What is it for?
Use it to prepare a document for narration, normalize its text, create a narrative version when needed, and render the result as an MP3.
Why use it?
It handles preparation of the text and audio rendering in one workflow, while requiring the spoken narrative to be prepared explicitly. It does not install the speech-generation backend.

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 A, and why

text-to-speech 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 10d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/backends/kokoro.sh, scripts/backends/lib/chunk_and_rewrite.py, scripts/backends/lib/inject_chapters.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.

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.

How it starts

The opening of the file, as written. The whole thing — 229 lines — stays where its author put it; the contents beside it link to each section on GitHub.

text-to-speech

Converts a text document to an MP3 audio file via a local TTS pipeline. The skill ships a wrapper script (synth-audio.sh) with a clean text → audio-file interface. The current backend is Kokoro-82M; swapping backends is a config change.

Does NOT install any TTS backend. See Backend Dependencies.

v2.0.0 breaking change: the narrative rewrite (L1) no longer runs automatically inside synth-audio.sh. If you're a driving Claude Code agent, dispatch a rewrite subagent first — see L1 Narrative Rewrite below — this is the normal way to use the skill now, not an edge case. A bare synth-audio.sh input.md output.mp3 with no existing narrative.txt now fails loudly instead of silently shelling out to claude --print (that nested call could inherit your session's output style/CLAUDE.md and leak meta-commentary into the audio — see L1 Narrative Rewrite for why). For headless/standalone use, pass --allow-inline-llm-rewrite.

Quick Start

${CLAUDE_SKILL_DIR}/scripts/synth-audio.sh input.md output.mp3 --skip-layer 1
# ^ requires <output.mp3>.workdir/narrative.txt to already exist — see
#   "L1 Narrative Rewrite" below for how to produce it (subagent dispatch)

Copy and configure backend settings (optional):

cp ${CLAUDE_SKILL_DIR}/templates/synth-backend.yaml.example ./synth-backend.yaml
# Edit synth-backend.yaml to match your setup

Backend Config (synth-backend.yaml)

Place synth-backend.yaml in your project root to override CLI defaults:

backend: kokoro        # current: kokoro | future: orpheus | ...

kokoro:
  voice: am_puck       # validated voice (R5, 5-round iteration)
  speed: 0.92          # validated speed — see Kokoro backend section
  phoneme_dict: ./phoneme-dict.yaml   # optional IPA overrides
  stress_hints: ./stress.yaml         # optional emphasis overrides

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.
