lang

A command for choosing the language used by Savant persona responses: English, Korean, Japanese, or Chinese. Savant is a set of named response personas.

In plain words
What is it for?
Changing the response language with a full language name or a supported shortcut, or choosing from a prompt when no language is given.
Why use it?
It lets users keep later persona responses in a preferred language instead of changing each response manually.

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/rlaope/claude-code-savant/lang
Clone the repo
git clone --depth 1 https://github.com/rlaope/claude-code-savant

Or install claude-code-savant, the plugin that ships this one along with the rest of its 29 commands, 1 agent, 1 MCP server.

Per session 14 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 425 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 2d 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.

Response by Language

Korean (한국어)

Japanese (日本語)

✅ 言語が**日本語**に設定されました

Important

After language is set, ALL subsequent Savant persona responses (Einstein, Shakespeare, Steve Jobs, Socrates) should be in the selected language. The personas maintain their character but speak in the chosen language.

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.
