Vibe sing

Skill harajlim/vibe-sing

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.From its SKILL.md

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

  1. 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

  2. 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.

  3. 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.
