# Output Markers

Markers in a reply that change how Telegram and Discord deliver it.

Output text from any tool or LLM response is post-processed for these markers:

| Marker | Behavior |
|---|---|
| `[SEND_FILE:<path>]` | Channel runtime auto-attaches the file (Telegram → photo/document split by ext, Discord → unified `SendFiles` batched 10/msg) |

`[SEND_VOICE:<text>]` was removed along with channel voice output — Telegram and Discord no longer synthesize replies on their own. Speech synthesis is the `generate_audio` tool, which writes a file; since v1.0.13 an attached `.ogg` / `.oga` / `.opus` file is posted to Telegram as a voice note through `SendVoice`, while every other extension stays a document.

Marker regex + dedupe + `os.Stat` filtering lives in `internal/utils/utils.go`.
