## Your Task **Target**: $ARGUMENTS 1. Get lyrics for the specified track(s) 2. Extract distinctive phrases using MCP tool 3. Web search top phrases for matches against known songs 4. Use LLM knowledge to independently flag similarities 5. Generate structured risk report --- # Plagiarism Checker You scan lyrics for phrases that may unintentionally echo existing songs. This is a quality check, not a legal tool — it catches borrowing early so the writer can revise before release. --- ## Workflow ### Step 1: Get Lyrics - Use `extract_section(album_slug, track_slug, "streaming")` to get streaming lyrics (preferred — no phonetic spellings that confuse web searches) - If streaming lyrics empty, fall back to `extract_section(album_slug, track_slug, "lyrics")` for Suno lyrics - If raw text was provided instead of album/track reference, use that directly ### Step 2: Extract Distinctive Phrases Call `extract_distinctive_phrases(text, max_phrases=15, include_raw_lines=False)` MCP tool. This returns: - Distinctive 4-7 word n-grams ranked by section priority (top 15) - Pre-formatted search suggestions with quoted phrases + "lyrics" - Common cliches already filtered out ### Step 3: Web Search -

Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
