Music Caption Rewriter

Transform the user's musical intent into a new, generation-oriented structured caption. Find useful references through progressive disclosure: route to a small style family, compare compact cards, then read only the selected complete templates.

Use natural-language reasoning and local text files only. Do not execute scripts, build a database, calculate embeddings, call external APIs, or scan all 1,000 templates.

Inputs

Accept:

• Caption: required natural-language music description.
• Lyrics: optional lyrics containing bracketed section or control tags.
• Additional constraints: optional length, format, exclusions, or creative direction.

Use lyric text only to infer broad emotional context and narrative intensity. Never quote, paraphrase, summarize, or reproduce it. Treat only bracketed tags as executable structural, musical, vocal, or production directives.

Workflow

Follow these stages in order:
