Suno Lyrics to Song

From Lyrics to a Listenable Song

A common challenge for songwriters and content creators is bridging the gap between a piece of text—the lyrics—and a finished, audio track. This gap often requires familiarity with complex production software, virtual instruments, and arranging techniques, leading to a workflow of tool-switching and iteration.

This skill connects lyrics directly to the Suno AI music generation model. Its core function is a deterministic, human-in-the-loop workflow that transforms text into audio, focusing specifically on that conversion process.

Core Workflow

The skill operates in distinct stages:

1. Input & Mode Determination: It accepts lyric text in various forms (complete, draft, or fragmented). Based on the user's instructions, it enters one of two modes:

   • Preserve Original Text: This mode strictly maintains every character, punctuation mark, and line order of the original lyrics. It only adds structural section tags (e.g., [Verse], [Chorus]) and adjusts spacing for clarity.
   • Optimize Lyrics: With explicit user permission, this mode refines the lyrics' wording, rhythm, rhyme, and structure for better musicality, while respecting any user-mandated "must-keep" lines.

2. Song Direction Generation: This is a critical step. The skill analyzes the lyrics to intelligently infer and propose a complete production blueprint, including:

   • A proposed title, genre, mood, tempo (BPM), and instrument palette.
   • A defined song structure with labeled sections (verse, chorus, bridge).
   • Vocal direction (e.g., assigning roles for duets, choirs) without directly specifying vocal timbre parameters.
     This proposal is presented as a "production card" for user review, which will specify the use of the suno-5.5 model.

3. Single Confirmation, Single Execution: User approval of the production card (containing final lyrics, title, and music direction) serves as the authorization to generate. The skill then initiates a single paid API call via the provided beatra.music.generate MCP tool and manages the task polling. It will not automatically regenerate or ask for repeated confirmations.

Capabilities, Boundaries & Considerations

The skill is designed for conversion, not all aspects of music creation:

• Hard Input Dependency: The core input must be lyrical text. It does not generate lyrics from a topic but excels at structuring fragments.
• Generation Dependency: Actual audio generation relies on the Suno model and beatra.ai backend. Output quality is subject to model limitations. Subjective review of the audio (e.g., judging the hook, vocal performance) is only possible if the host environment can play it.
• Cost and Modification: Generation is a paid operation. If the user requests changes after generation, a new production card must be created and confirmed, which constitutes a new paid task.
• Lyric Ownership: In optimize mode, the skill adheres to "must-keep" rules, but the user is responsible for the final optimized lyric text.
• Technical Stack: All remote operations must be executed through the skill's bundled scripts/mcp_client.py client, with no fallback to REST/OpenAPI. The skill includes a silent auto-update mechanism to ensure it uses the latest official version from fixed, secure paths.
