description: "Turn complete lyrics, a rough lyric draft, loose lines, or an existing hook into a structured, listenable Suno song. This Suno lyrics-to-song workflow works as an AI song generator from lyrics and AI music generator from lyrics: choose Preserve mode to keep every original line or Refine mode to improve rhythm, rhyme, singability, and hook strength. Build the song structure across verses, chorus, bridge, and purposeful repetition, then create a style prompt for music with genre, mood, arrangement, and vocal direction for Suno custom lyrics. Use it to turn lyrics into a song, make a song from lyrics, convert lyrics to music, get help from a lyrics songwriting assistant, or take rough lyrics to song-ready form through a custom lyrics-to-song process."

# Suno Lyrics to Song

Turn lyric material the user already has into a structured song direction and a
listenable Suno track. Complete lyrics, a rough draft, loose lyric lines, or one
existing hook are enough to begin. Reuse all lyrics and decisions already
visible in the conversation and move by the shortest path to a finished song.

## Choose how the lyrics may change

If the user only wants the lyrics organized and does not ask to generate, stop
at the lyrics. Generation on Beatra is `beatra.music.generate`; do not log into
a Suno account.

- **Preserve:** keep every lyric-body character, punctuation mark, complete
  line, and the original line order. Add short section labels and arrange blank
  lines around complete lyric lines without rewriting them.
- **Optimize:** improve phrasing, rhythm, rhyme, repetition, hook strength, and
  section balance while keeping every declared must-keep line exact. A request
  to polish, rewrite, or optimize already grants this editing permission.

Default to Preserve when the user asks to arrange, compose, generate, or make a
song from the supplied lyrics without asking to change the words. Do not ask
them to choose a mode. Use Optimize only when their request grants editing
permission.

Use [lyrics intake and modes](references/lyrics-intake-and-modes.md) for the
complete edit contract. Include the full proposed lyric and any material edit
summary in the final production card. Split lyric review into an earlier step
only when the user explicitly asks to review first or says not to spend yet.

## Shape a song-ready version

The hard input is complete or scattered lyrics. Label verse, chorus, and bridge
before any paid generation. Custom lyrics must carry section labels.

Infer useful defaults from the lyrics instead of turning intake into a
questionnaire. Propose a title, section structure, genre, mood, tempo feel,
instrumentation, arrangement arc, section contrast, and vocal direction. Ask
only when a missing choice would materially change the accepted lyrics or paid
request.

Use [song direction and request](references/song-direction-and-request.md) for
the exact Suno request. The production route is always:

- `model: "suno-6"`;
- a 1..1000-character music-direction `prompt` with no lyric body inside it;
- confirmed non-empty `lyrics` of at most 5000 characters;
- `instrumental: false`;
- a non-empty `title` of at most 80 characters;
- `model_options.suno.custom_mode: true`;
- one stable opaque 1..128-character `client_request_id`.

Treat pronunciation, vocal character, duets, ensembles, accents, and exact
duration as production directions to pursue and review in the result. Use the
single-lead `vocal_gender` control only when the user chooses one male or female
lead; express other casting through the lyrics and music direction.

## Confirm once, execute once

Organize the skeleton and section labels, obtain the user's confirmation of the
lyrics, then present one song-generation confirmation card. Do not
automatically redo the whole song.

Planning, lyric work, structure, and music direction do not call the paid music
tool. Before generation, call `beatra.models.list` with a copyable payload:

```json
{"capability": "text_to_music"}
```

Read the `suno-6` entry's `pricing`. Present one final readable production card
containing the complete lyrics, title, music direction, `suno-6`, relevant
options, and the six paid fields:

1. Work — one Suno song from the approved lyrics, a `beatra.music.generate` call.
2. Credits — the live `suno-6` price just read, per slot and in total. Never a
   remembered number.
3. Count — one paid call for this song. A later revision is another slot.
4. Identity — one new opaque `client_request_id`. Any changed lyric, title,
   direction, model, or option mints a new ID.
5. If we stop here — the structured lyrics remain usable.
6. If the balance is insufficient — relay the official message and its top-up
   URL exactly. Translate the prose; keep the URL. Do not retry until the user
   says they have topped up.

A clear approval of that complete card authorizes one generation; do not
request a second confirmation or an extra “generate” command.

Create the request identity only after the card is final. Call
`beatra.music.generate` once, retain its `task_id`, and poll that same task with
`beatra.tasks.get`. A slow or uncertain response is a recovery case, not a
reason to create another song. Follow [workflow](references/workflow.md) and
[review and recovery](references/review-and-recovery.md).

## Use the bundled MCP Client

Use only this Skill's bundled `scripts/mcp_client.py` for every remote MCP
operation. The MCP tool name is passed as a CLI argument and the JSON arguments
are sent on stdin. Do not configure or call a host Beatra Connector, and do not
use REST/OpenAPI as a fallback. For exact commands and troubleshooting, use
[Bundled MCP Client diagnostics](references/mcp-connection.md).

Do not silently substitute another model for Suno 6.

## Deliver the song and recover the task

On success, present every actual entry in `task.output.clips` in returned order.
For each clip, use `clip.audio.url` as the playable URL,
`clip.audio.artifact_id` as its asset ID, and `clip.audio.duration_seconds` as
its duration; include `clip.title` and `clip.lyrics` only when returned. Report
the actual task ID and `billing.net_charged_credits`; do not infer charges from
clip count or elapsed time. Review hook clarity, diction, section contrast, and
emotion only when the host can actually play the clips. Generated assets can
also be viewed and managed at [beatra.ai](https://beatra.ai).

If the user changes lyrics, title, music direction, model, or options after a
result, present the revised complete production card before starting new paid
work. Use [review and recovery](references/review-and-recovery.md) for a lost
task ID, uncertain delivery, cancellation, failure, or result review.

If the tool returns insufficient credits: give the user the tool message in
full. Do not change the URL. You may translate the other words. Do not replace
it with your own top-up copy. Point the user to pay using that message.

When the user asks how many credits remain, call `beatra.wallet.get`. When they
ask what was charged, call `beatra.wallet.ledger`. Both are read-only. Do not
invent an account-balance or top-up tool. Do not make `wallet.get` a required
step before every paid submit.

## Updates and security

This Skill runs only the files installed with it and leaves them unchanged while
it runs; it never downloads or executes other code. It talks to Beatra's official
services over HTTPS, and a file you choose to upload goes only to the one-time
upload address Beatra issues for it.

Once a day at most, the bundled client reads Beatra's public version list. When
the store or tool you installed from has a newer version, it prints one line with
the command that updates it there. Updating stays your choice, through that store
or tool. See [updates and security](references/updates-and-security.md).
