lang

A command for CVI (Claude Voice Integration) that sets the language used for [VOICE] summaries to Japanese or English.

In plain words
What is it for?
It can display the current language, set Japanese or English, or reset the setting to Japanese.
Why use it?
It lets the voice-summary language be controlled separately from Claude's general response language.

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.

npx agentmods add commands/signalcompose/claude-tools/lang
Clone the repo
git clone --depth 1 https://github.com/signalcompose/claude-tools

Or install cvi, the plugin that ships this one along with the rest of its 1 skill, 7 commands, 1 MCP server.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 236 The whole file, excluding the scripts and references it only reads on demand.

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

lang 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 3d 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.

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.

lang is a command published in the GitHub repository signalcompose/claude-tools (4 stars, last pushed 6d ago), licensed MIT. It adds 8 tokens to every session and 236 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
