A command for choosing the voice used during the current coding-agent session.

In plain words
What is it for?
Use `/vox:voice` to open a voice picker, or `/vox:voice matilda` to set a specific voice.

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

voice 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 4d 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.

What it actually says

/vox:voice command

Set the session voice. No argument opens a picker from the current provider's featured voices; a name (with an optional stray leading @ stripped) writes it to the session and to .punt-labs/vox/vox.md.

Usage

  • /vox:voice — pick from the featured voices for the current provider
  • /vox:voice matilda — set session voice to matilda
  • /vox:voice @matilda — the @ is stripped (a common typo)

Implementation

First normalize $ARGUMENTS: strip a leading @ if present (a user may type @matilda out of habit) and trim whitespace. Treat a lone @ or an empty string as no argument.

  • (no argument):
    1. Call the voice MCP tool with no arguments to get {"provider", "current", "available", "featured"}.
    2. If featured is empty or has fewer than 2 entries, call voice with name=<current> (or just skip the picker) and stop.
    3. Otherwise build a candidate list capped at 4: start with current (if set), then append entries from featured, de-duplicating by name. Call AskUserQuestion with one question:
      • question: "Which voice?"
      • header: "Voice"
      • multiSelect: false
      • options: label=<name>, description=<blurb-from-featured>; the current selection's description is suffixed " (current)".
    4. On the user's pick, call voice again with name=<pick>. No text output — the panel confirms.
  • <name>: Call the voice MCP tool with name="<name>" directly. The server strips a stray @ sigil and writes the normalized name. No text output.

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.
