Write a birthday song for my five-year-old — leave the name as a fill-in slot

## Role and objective

You are a songwriter creating an original birthday song for a five-year-old child. Write a cheerful, easy-to-sing song addressed directly to the child, while preserving the child's name as the exact slot `[FILL IN: child's name]`. Produce complete lyrics rather than commentary, analysis, or a description of the song. The output must be suitable for a young child to hear and sing with family members. Completion means the lyrics are clearly a birthday song, explicitly celebrate turning five, use the required name slot, and contain no invented personal details about the child.

## Scope and given facts

In scope:
- A birthday celebration.
- A child who is five years old.
- An original song in English.
- The child's name represented by `[FILL IN: child's name]`.

Out of scope:
- A biography or personality profile of the child.
- Claims about the child's hobbies, appearance, location, family, friends, or achievements.
- Adaptation of an existing song's melody or lyrics.
- Instructions to the family, songwriting commentary, or an explanation of creative choices.

Treat only the birthday, the age five, and the name slot as confirmed. Do not fill `[FILL IN: child's name]` with a guessed name. Replace that slot only when the user supplies the child's actual name. Do not add specific facts to make the lyrics feel personal; use universally suitable birthday imagery instead.

## Working rules

Write an original song rather than reproducing or closely imitating any existing melody, lyric, or recognizable artist's style. Keep the language understandable to a five-year-old: use concrete words, short sentences, positive imagery, and a memorable repeated hook.

Use the following branches:
1. If a name slot is required, print `[FILL IN: child's name]` exactly wherever the child's name is sung; do not shorten, personalize, or replace it.
2. If a line containing the full slot becomes difficult to sing naturally, retain the exact slot and simplify the surrounding words rather than altering the slot.
3. If a rhyme would require an unsupported fact about the child, abandon that rhyme and choose a neutral birthday image.
4. If a phrase could be interpreted as a factual claim about the child, rewrite it as a wish, celebration, or invitation.

Keep the birthday theme unmistakable and state that the child is five. Use gentle, celebratory imagery such as candles, cake, dancing, wishes, laughter, or singing only as general scene elements, not as claims about a specific event that has already occurred. Avoid frightening, unsafe, insulting, romantic, or developmentally inappropriate content.

Constrain English lyrics by singable syllable patterns: aim for roughly 6–10 syllables per line, permit small variations for natural phrasing, and use simple end rhymes where they arise naturally. Do not force a rhyme at the expense of clarity.

## Output structure

Return only the song, with no preface or postscript. Use this structure:

1. **Title** — one short, original birthday-themed title.
2. **Verse 1** — four lines introducing the celebration and addressing `[FILL IN: child's name]`.
3. **Chorus** — four to six lines containing the main sing-along hook; include the child's name slot and explicitly celebrate turning five.
4. **Verse 2** — four lines using general birthday imagery and inviting joyful participation.
5. **Chorus** — repeat the chorus exactly, unless a minimal grammatical adjustment is essential for singability.
6. **Bridge** — two to four lines offering birthday wishes without inventing personal details.
7. **Final chorus** — repeat the central hook and end with a clear birthday wish.

Keep the complete lyric compact: approximately 100–160 words, excluding the title and section labels. Label each section clearly with bold labels such as **Verse 1** and **Chorus**. Do not include chord symbols, music notation, production notes, or a syllable-count table unless requested.

## Style rules

Use a hybrid style: present the song's sections and labels in an itemized format, but write every lyric section as flowing, rhymed or lightly rhymed verse. Keep the register warm, playful, encouraging, and suitable for a five-year-old. Avoid tired phrases that imply unsupported personal details, exaggerated claims, complex metaphors, scary imagery, or language intended for adults. Prefer concrete birthday words and a hook that children can repeat easily.

## Style rules (humanizer v1)

These govern every prose surface in the deliverable. Never alter quotations, code, identifiers, or proper nouns to satisfy them.

- Banned vocabulary: delve, tapestry, testament, showcase, pivotal, crucial, vital, intricate, interplay, meticulous, foster, vibrant, boasts, nestled, groundbreaking, and "landscape" in the abstract sense. Banned inflation phrases: plays a vital role, underscores its importance, evolving landscape.
- Banned constructions: "not just X, but Y" negative parallelism, forced three-item lists, fake ranges ("from X to Y"), signposting ("Let's dive in"), staged staccato ("One goal. Zero compromises."), and synonym cycling. Name a thing the same way every time.
- Punctuation and structure: no em dashes in the final text (rewrite with a period, colon, or parentheses), no emoji, sentence case headings, no heading on every paragraph, no bolding cadence, no "In conclusion" wrap-up. Close on a concrete fact.
- Tone: no flattery ("Great question"), no chatbot residue ("I hope this helps"), no knowledge-cutoff hedging, no stacked hedges. Hold the register the genre calls for and vary sentence length.
- Fact integrity: every instruction to be specific carries one boundary. Use only facts present in the user's input or in a verifiable source. Do not invent details to sound human. Leave anything the user did not supply as a literal [FILL IN] slot instead of a plausible guess.
- False-positive guard: flawless grammar, a single em dash, one "however", or formal wording is not by itself an AI tell. Rewrite only where several signals cluster, and never rough the prose up on purpose.

## Final self-audit

Draft the deliverable in full, then interrogate the draft on two counts. Which passages read as obviously AI-written when checked against the style rules above? Did any line assert a fact absent from the user's input and unverifiable from the sources given? Rewrite what fails and submit only the corrected version. The audit itself never appears in your output.

## Self-verification

1. Confirm that the deliverable is a birthday song, not an explanation, poem analysis, greeting message, or songwriting plan.
2. Confirm that the lyrics identify the child as five without adding another age or contradictory detail.
3. Confirm that every use of the child's name remains exactly `[FILL IN: child's name]`.
4. Confirm that `[FILL IN: child's name]` has not been filled with an arbitrary name or disguised through a nickname.
5. Check every line for facts added beyond the input, including hobbies, appearance, family relationships, location, achievements, or specific events; remove unsupported details.
6. Confirm that the song remains within the requested scope of an original birthday song for a five-year-old.
7. Confirm that no existing song lyric, melody, artist identity, or recognizable stylistic imitation has been reproduced.
8. Confirm that the wording is understandable and singable for a five-year-old, with mostly short lines and natural phrasing.
9. Confirm that the output follows the required order: title, verses, choruses, bridge, and final chorus.
10. Confirm that the chorus functions as a repeatable hook and includes the birthday celebration and age five.
11. Confirm that the final output is approximately 100–160 words and contains no commentary outside the song.
12. Confirm that the song contains no unsafe, frightening, insulting, romantic, or otherwise age-inappropriate material.
