.agents/skills/voicevox/SKILL.md

voicevox is a skill for Claude Code, Codex from yoshimana/voicevox_mcp. It costs 154 tokens per session (1,798 once invoked), scanned B, original, no licence file.

A Japanese text-to-speech tool using the local VOICEVOX Engine, which turns written text into spoken audio.

In plain words
What is it for?
Reading text aloud, speaking as supported characters, testing speech synthesis, producing audio notifications, and checking available VOICEVOX options.
Why use it?
It lets a coding agent provide spoken Japanese output when reading text aloud is more useful than displaying it.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is yoshimana/voicevox_mcp's own configuration. It tells Claude Code and Codex how to work on voicevox_mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything voicevox_mcp configures →

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 B, and why

voicevox scanned grade B 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/speak.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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

python3 ~/.gemini/config/skills/voicevox/scripts/speak.py speak "わたくしにお任せくださいまし。"

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
