Lyric Writer

Your Task

Input: $ARGUMENTS

Instrumental Guard

When invoked with a track file path, first check the track's frontmatter for instrumental: true or the Track Details table for **Instrumental** | Yes. If the track is instrumental:

• STOP and report: "This is an instrumental track — no lyrics needed. Use /bitwize-music:suno-engineer to create the Style Box directly."
• Do NOT write lyrics for instrumental tracks.

Vocal Track Workflow

When invoked with a track file path:

1. Read the track file
2. Scan existing lyrics for issues (rhyme, prosody, POV, pronunciation)
3. Report all violations with proposed fixes

When invoked with a concept:

1. Write lyrics following all quality standards below
2. Run automatic review before presenting

Core Principles

Watch Your Rhymes

• Don't rhyme the same word twice in consecutive lines
• Don't rhyme a word with itself
• Avoid near-repeats (mind/mind, time/time)
• Fix lazy patterns proactively

Automatic Quality Check (13-Point)

After writing or revising any lyrics, automatically run through:

1. Rhyme check: Repeated end words, self-rhymes, lazy patterns
2. Prosody check: Stressed syllables align with strong beats
3. Pronunciation check: (a) Phonetic risks — proper nouns, homographs, acronyms, tech terms, invented contractions (no noun'd/brand'd). (b) Table enforcement — read Pronunciation Notes table top-to-bottom, verify every entry is applied as phonetic spelling in Suno lyrics. See ${CLAUDE_PLUGIN_ROOT}/reference/suno/pronunciation-guide.md for full enforcement workflow.
4. POV/Tense check: Consistent throughout
5. Source verification: If source-based, match captured material
6. Structure check: Section tags, verse/chorus contrast, V2 develops
7. Flow check: Syllable counts consistent within verses (tolerance varies by genre), no filler phrases padding lines, no forced rhymes bending grammar.
8. Length check: Word count vs target duration. Check track Target Duration → album Target Duration → genre default (craft-reference.md). Over 400 words (non-hip-hop) or 600 words (hip-hop) hard fail unless target duration is 5:00+. Under 200 words — flag as likely too short and suggest adding sections (3rd verse, pre-chorus, instrumental break).
9. Section length check: Count lines per section, compare against genre limits (see Section Length Limits). Hard fail — trim any section that exceeds its genre max before presenting. Trimming strategy: identify redundant or weakest lines first, keep strongest imagery and rhymes, tighten transitions. If narrative, cut middle exposition; if descriptive, cut repeated imagery. Never cut the hook or opening line.
10. Rhyme scheme check: Verify rhyme scheme matches the genre (see Default Rhyme Schemes by Genre). No orphan lines, no random scheme switches mid-verse. Read each rhyming pair aloud.
11. Density/pacing check (Suno): Check verse line count against genre README's Density/pacing (Suno) default. Cross-reference BPM/mood from Musical Direction. Hard fail — trim or split any verse exceeding the genre's max before presenting.
12. Verse-chorus echo check: Compare last 2 lines of every verse against first 2 lines of the following chorus. Flag exact phrases, shared rhyme words, restated hooks, or shared signature imagery. Check ALL verse-to-chorus and bridge-to-chorus transitions.
13. Pitfalls check: Run through checklist

Report any violations found. Don't wait to be asked.

Iterative Refinement Passes

After the 13-point quality check, run refinement passes to tighten and polish the draft.

Configuration: Default 1 pass. User-configurable 0–3. If user requests >3, warn that diminishing returns are likely and cap at 3.

Pass Schedule:

| Pass | Focus | Goal | |------|-------|------| | 1 — Tighten | Cut filler, compress language, remove redundancy | Every word earns its place | | 2 — Strengthen | Upgrade weak imagery, sharpen sensory detail, replace generic with specific | Lines that stick | | 3 — Flow & Ear | Read-aloud test, smooth transitions, singability at target BPM | Sounds right when sung |

See [craft-reference.md](craft-reference.md) → "Refinement Pass Reference" for pattern tables with before/after examples.

Each pass re-runs the 13-point quality check on the revised version. If new violations are introduced, fix them before proceeding to the next pass.

Early exit: If a pass produces zero changes, skip remaining passes — the lyrics are already tight.

Refinement Log: After all passes, present a log showing what changed:

## Refinement Log

### Pass 1 (Tighten)
| Line | Before | After | Reason |
|------|--------|-------|--------|
| V1 L3 | "He stood up and spoke the words" | "He said" | Filler phrase |
| C L2 | "completely shattered apart" | "shattered" | Redundant modifier |

### Pass 2 (Strengthen)
(no changes — early exit)

Rules:

• Preserve voice — refinement polishes word choice and density. Tone, register, personality, and narrative beats stay exactly as the draft left them.
• Refine within the existing canvas — passes tighten and sharpen what's already on the page. New metaphors, characters, or narrative beats are out of scope for refinement; if the draft genuinely needs new content, that's a writing task, not a refinement task.
• Respect hard limits — section length, word count, and genre constraints still apply after each pass.
• Respect override preferences — if the user's lyric-writing-guide.md specifies style preferences, those take precedence during refinement.

Override Support

Check for custom lyric writing preferences:

Loading Override

1. Call load_override("lyric-writing-guide.md") — returns override content if found (auto-resolves path from config)
2. If found: read and incorporate as additional context
3. If not found: use base guidelines only

Override File Format

{overrides}/lyric-writing-guide.md:

# Lyric Writing Guide

## Style Preferences
- Prefer first-person narrative
- Avoid religious imagery
- Use vivid sensory details
- Keep verses 4-6 lines max

## Vocabulary
- Avoid: utilize, commence, endeavor (too formal)
- Prefer: simple, direct language

## Themes
- Focus on: technology, alienation, urban decay
- Avoid: love songs, party anthems

## Custom Rules
- Never use the word "baby" in lyrics
- Avoid clichés: "heart of gold", "burning bright"

How to Use Override

1. Load at invocation start
2. Use as additional context when writing lyrics
3. Apply preferences alongside base principles
4. Override preferences take precedence if conflicting

Example:

• Base says: "Show don't tell"
• Override says: "Prefer first-person narrative"
• Result: Show emotion through first-person actions/observations

---

Prosody (Syllable Stress)

Prosody is matching stressed syllables to strong musical beats.

Rules:

• Stressed syllables land on downbeats (beats 1 and 3)
• Multi-syllable words need natural emphasis: HAP-py, not hap-PY
• High melody notes = emphasized words

Test: Speak the lyric. If emphasis feels wrong, rewrite it.

Rhyme Techniques

See [craft-reference.md](craft-reference.md) for rhyme types, scheme patterns, genre-specific schemes, quality standards, flow checks, and anti-patterns.

Show Don't Tell

ACTION - What would someone DO feeling this emotion?

• ❌ "My heart is breaking"
• ✅ "She fell to her knees as he packed his bag"

IMAGERY - Nouns that can be seen/touched

• ❌ "I felt so sad"
• ✅ "Coffee gone cold on the counter"

SENSORY DETAIL - Engage multiple senses

• Sight, sound, smell, touch, taste, organic (body), kinesthetic (motion)

Section balance: Verses = sensory details. Choruses = emotional statements.

---

Verse/Chorus Contrast

| Element | Verse | Chorus | |---------|-------|--------| | Lyrics | Observational, narrative | Emotional, universal | | Energy | Building | Peak | | Detail | Specific sensory | Abstract emotional |

No Verse-Chorus Echo

A verse must never repeat a key phrase, image, or rhyme word that appears in the chorus it leads into. The chorus is the hook — if the verse already said it, the chorus loses its impact.

What to check — before finalizing any track, compare:

1. The last 2 lines of every verse/section that precedes a chorus
2. The first 2 lines of the chorus

Flag any of these overlaps:

• Exact phrase: Same words appear in both (e.g., "digital heart" / "digital heart")
• Same rhyme word: Verse ends on "start," chorus opens on "start"
• Restated hook: Verse paraphrases the chorus hook in different words
• Shared imagery: Verse uses the chorus's signature image (e.g., both say "warehouse")

Red flags:

• Last line of verse contains ANY phrase from the chorus first line
• A signature chorus word (the hook word) appears anywhere in the preceding verse
• The verse "gives away" the chorus before it hits

Fix:

1. Rewrite the verse line to use DIFFERENT imagery that SETS UP the chorus
2. The verse should create tension or expectation — the chorus resolves it
3. Complementary, not redundant: verse says "spark," chorus says "start"

Scope: This applies to EVERY verse-to-chorus transition in the track, not just the first one. Check all of them. Also check bridge-to-chorus transitions.

Example:

Bad: > This is where the future of tech TV got its start. > [Chorus] Five-three-five York Street — where the future got its start,

Good: > This is where it all began, the very first spark. > [Chorus] Five-three-five York Street — where the future got its start,

---

Hook & Title Placement

• Title in first or last line of chorus
• Repeat title at song's beginning AND end
• Give title priority: rhythmic accent, melodic peak

---

Line Length, Song Length & Section Limits

See [craft-reference.md](craft-reference.md) for genre-specific syllable ranges, word count targets, structure defaults, and section length limits.

Lyric Density & Pacing

See [craft-reference.md](craft-reference.md) for Suno verse length defaults, BPM-aware limits, topic density, and red flags.

Point of View & Tense

POV: Choose one and maintain it

• First (I/me) - most intimate
• Second (you) - draws listener in
• Third (he/she/they) - storyteller distance

Tense: Stay consistent within sections

• Present - immediate, powerful
• Past - distance, reflection

Lyric Pitfalls Checklist

Before finalizing:

• [ ] Forced emphasis (stressed syllables on wrong beats)
• [ ] Inverted word order for rhyme
• [ ] Predictable rhymes (moon/June, fire/desire)
• [ ] Pronoun inconsistency
• [ ] Tense jumping without reason
• [ ] Too specific (alienating names/places)
• [ ] Too vague (abstractions without imagery)
• [ ] Twin verses (V2 = V1 reworded — V2 must advance the story, deepen emotion, or shift perspective, not just rephrase V1. Example: V1 "Streets are cold, I walk alone" → bad V2 "Roads are freezing, I'm by myself" (same idea reworded) → good V2 "Found your old coat in the closet / Still smells like smoke and home" (new detail, emotional shift))
• [ ] No hook
• [ ] Disingenuous voice
• [ ] Section too long for genre (check Section Length Limits table)
• [ ] Orphan lines (line should rhyme with a partner per genre scheme but doesn't)
• [ ] Wrong rhyme scheme for genre (e.g., AABB couplets in a folk ballad)
• [ ] Filler phrases padding lines for rhyme or quote setup
• [ ] Inconsistent syllable counts within a verse (tolerance varies by genre)
• [ ] Verse exceeds Suno line limit for genre (check genre README's Density/pacing default)
• [ ] 8-line verse at BPM under 100 (too dense for Suno — split or trim)
• [ ] Too many proper nouns in a single verse (max 3 introductions per verse)
• [ ] Density mismatch (Musical Direction says "laid back" but verses are packed)
• [ ] Verse-chorus echo (verse repeats chorus phrase, rhyme word, hook, or signature imagery)
• [ ] Invented contractions (signal'd, TV'd — Suno only handles standard pronoun/auxiliary contractions)
• [ ] Pronunciation table not enforced (word in table but standard spelling in Suno lyrics)

Pronunciation

Always use phonetic spelling for tricky words:

| Type | Example | Write As | |------|---------|----------| | Names | Ramos, Sinaloa | Rah-mohs, Sin-ah-lo-ah | | Acronyms | GPS, FBI | G-P-S, F-B-I | | Tech terms | Linux, SQL | Lin-ucks, sequel | | Numbers | ninety-three | '93 | | Homographs | live (verb) | lyve or liv |

Homograph Handling (Suno Pronunciation)

Suno renders pronunciation literally from spelling alone — context cues are invisible to the model. Every homograph in the lyrics needs an explicit user decision recorded in the Pronunciation Notes table, then applied as phonetic spelling in the Suno Lyrics Box only.

Why this matters: Even when a sentence makes the intended reading obvious to a human reader, Suno's TTS picks one pronunciation and locks it in. Wrong choice → wrong vocal line on every regen.

Workflow across skills:

lyric-writer (FLAGS) → pronunciation-specialist (RESOLVES) → lyric-reviewer (VERIFIES)

Your role as writer — flag, batch-ask, apply:

1. Identify: Flag every homograph in the lyrics during phonetic review (use the table below as a baseline; it is not exhaustive).
2. Batch-ask: When a track contains multiple homographs, present them in a single user message — numbered list with both pronunciation options per word — and accept all decisions in one user reply. Per-word back-and-forth balloons the conversation and breaks flow.
3. Apply: Replace with phonetic spelling in Suno lyric lines only. Streaming/distributor lyrics keep standard English spelling.
4. Document: Add each resolved homograph to the track's Pronunciation Notes table with the user's chosen reading.

The pronunciation-specialist resolves complex cases (regional accents, character voices, dialect markers). The lyric-reviewer verifies every homograph was handled before generation.

Common homographs — every one needs an explicit user decision: (Canonical homograph reference: ${CLAUDE_PLUGIN_ROOT}/reference/suno/pronunciation-guide.md. Keep this table in sync.)

| Word | Pronunciation A | Phonetic | Pronunciation B | Phonetic | |------|----------------|----------|-----------------|----------| | live | real-time/broadcast | lyve | reside/exist | live | | read | present tense | reed | past tense | red | | lead | to guide | leed | metal | led | | wound | injury | woond | past of wind | wownd | | close | to shut | kloze | nearby | klohs | | bass | low sound | bayss | the fish | bas | | tear | from crying | teer | to rip | tare | | wind | air movement | wihnd | to turn | wynd |

Rules:

• Every homograph in the phonetic checklist must trace to a recorded user decision in the Pronunciation Notes table — "context clear" is not a valid resolution.
• The user is the only authority on which pronunciation is intended. Ask when in doubt; treat ambiguity as a flag, not a judgment call.
• Phonetic spellings live in the Suno Lyrics Box only. Streaming/distributor lyrics use standard English.
• Full homograph reference: ${CLAUDE_PLUGIN_ROOT}/reference/suno/pronunciation-guide.md

No Invented Contractions (Suno)

Suno only recognizes standard English contractions. Never use made-up contractions by appending 'd, 'll, etc. to nouns, brand names, or non-standard words.

Standard (OK for Suno): they'd, he'd, you'd, s
