What its author says it does

Copied from the file, not written here

Generate a song that captures the vibe of the current Claude Code session. Reads the session transcript, asks Gemini for a non-corny user-centric music prompt, calls Google Lyria, and auto-plays the result. Args: `pro` for a ~2 minute version (default is 30s clip), `stop` to kill the currently-playing song.

When the user invokes /vibe-sing, run the pipeline script. It distills the current session's emotional vibe into a Lyria music prompt (via Gemini) and composes a song.

What to do

Run the skill's launcher, passing through the user's argument verbatim:
```
~/.claude/skills/vibe-sing/run.sh <arg-if-any>
```
Recognized arguments:
- (none) — 30-second clip (default)
- pro — ~2 minute full song
- stop — kill the currently-playing song
The script handles everything: finding the current session's transcript JSONL, slicing the recent vibe-relevant text (skipping tool calls/results), calling Gemini for a mood prompt, calling Lyria, saving the mp3 to ~/.claude/skills/vibe-sing/generations/, and open-ing the file so it plays.
After the script returns, the last line of stdout is a JSON object with mood_prompt, audio_file, model, and gemini_model. Report back to the user in at most two sentences:
- One sentence quoting the mood prompt Gemini chose.
- One sentence with the file path.
Do not describe what the song is "about" — let the audio speak. Do not add commentary about whether the vibe seems right. The user will hear it and decide.

Errors

If the script fails (missing GOOGLE_API_KEY, no transcript, API error), surface the stderr message verbatim and stop — do not retry.

Notes

Requires GOOGLE_API_KEY in .env inside the skill dir (or in the environment).
The transcript reader explicitly skips tool calls and tool results to keep the vibe extraction focused on conversational tone.
Both the transcript filter and the Gemini system prompt are designed to prevent corny "song about debugging React" output — the mood prompt should never reference programming, files, or specific topics.
