free to diverge. Tree copied sans upstream .git; upstream remote added for
future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19.

+# sag
+
+Use `sag` for ElevenLabs TTS with local playback.
+
+API key (required)
+
+- `ELEVENLABS_API_KEY` (preferred)
+- `SAG_API_KEY` also supported by the CLI
+
+Quick start
+
+- `sag "Hello there"`
+- `sag speak -v "Roger" "Hello"`
+- `sag voices`
+- `sag prompting` (model-specific tips)
+
+Model notes
+
+- Default: `eleven_v3` (expressive)
+- Stable: `eleven_multilingual_v2`
+- Fast: `eleven_flash_v2_5`
+
+Pronunciation + delivery rules
+
+- First fix: respell (e.g. "key-note"), add hyphens, adjust casing.
+- Numbers/units/URLs: `--normalize auto` (or `off` if it harms names).
+- Language bias: `--lang en|de|fr|...` to guide normalization.
+- v3: SSML `<break>` not supported; use `[pause]`, `[short pause]`, `[long pause]`.
+- v2/v2.5: SSML `<break time="1.5s" />` supported; `<phoneme>` not exposed in `sag`.
+
+v3 audio tags (put at the entrance of a line)
+
+- `[whispers]`, `[shouts]`, `[sings]`
+- `[laughs]`, `[starts laughing]`, `[sighs]`, `[exhales]`
+- `[sarcastic]`, `[curious]`, `[excited]`, `[crying]`, `[mischievously]`
+- Example: `sag "[whispers] keep this quiet. [short pause] ok?"`
+
+Voice defaults
+
+- `ELEVENLABS_VOICE_ID` or `SAG_VOICE_ID`
+
+Confirm voice + speaker before long output.
+
+## Chat voice responses
+
+When the user asks for a "voice" reply (e.g., "crazy scientist voice", "explain in voice"), generate audio and send it:
+
+```bash
+# Generate audio file
+sag -v Clawd -o /tmp/voice-reply.mp3 "Your message here"
+
+# Then include in reply:
+# MEDIA:/tmp/voice-reply.mp3
+```
+
+Voice character tips:
+
+- Crazy scientist: Use `[excited]` tags, dramatic pauses `[short pause]`, vary intensity
+- Calm: Use `[whispers]` or slower pacing
+- Dramatic: Use `[sings]` or `[shouts]` sparingly
+
+Default voice for Clawd: `lj2rcrvANS3gaWWnczSX` (or just `-v Clawd`)
