messages.* delivery behaviour, text-to-speech, and the talk.* defaults for Talk mode.

Messages

{
  messages: {
    responsePrefix: "🦞", // or "auto"
    ackReaction: "👀",
    ackReactionScope: "group-mentions", // group-mentions | group-all | direct | all | off | none
    queue: {
      mode: "steer", // steer (default) | followup | collect | interrupt
      cap: 20,
      drop: "summarize", // old | new | summarize (default)
      byChannel: {
        whatsapp: "followup",
        telegram: "followup",
      },
    },
    inbound: {
      debounceMs: 2000, // 0 disables ordinary burst batching
      byChannel: {
        whatsapp: 5000,
        slack: 1500,
      },
    },
  },
}

Response prefix

Per-channel/account overrides: channels.<channel>.responsePrefix, channels.<channel>.accounts.<id>.responsePrefix.

Resolution (most specific wins): account → channel → global. "" disables and stops cascade. "auto" derives [{identity.name}].

Template variables:

Variable Description Example
{model} Short model name claude-opus-4-6
{modelFull} Full model identifier anthropic/claude-opus-4-6
{provider} Provider name anthropic
{thinkingLevel} Current thinking level high, low, off
{identity.name} Agent identity name (same as "auto")

Variables are case-insensitive. {think} is an alias for {thinkingLevel}.

Ack reaction

Queue

Use messages.inbound.debounceMs for the global pre-queue debounce window.

Inbound debounce

Batches rapid text-only messages from the same sender into a single agent turn after a quiet window. Media/attachments flush immediately. Control commands bypass debouncing.

Batching is a bounded timing heuristic, not a guarantee that every part of a long message becomes one turn. See Inbound debouncing and Telegram inbound text batching.

Other message keys

TTS (text-to-speech)

{
  tts: {
    auto: "off", // off (default) | always | inbound | tagged

      microsoft: {
        speakerVoice: "en-US-MichelleNeural",
        lang: "en-US",
        outputFormat: "audio-24khz-48kbitrate-mono-mp3",

      },
    },
  },
}

The global preferences path is machine state (default ~/.apus/settings/tts.json; override with APUS_TTS_PREFS). Advanced multi-agent setups can set agents.entries.<id>.tts.prefsPath for distinct per-agent preference stores.
