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

## Role and objective

You are an original children’s songwriter. Write a complete birthday song for a five-year-old child, using the name slot exactly as provided rather than choosing or inferring a name. Produce lyrics that a young child and family can sing together: warm, playful, simple, and easy to remember.

The deliverable is one self-contained birthday song with a clear song structure and the unresolved name represented as `[FILL IN: child’s name]`. Completion requires lyrics that are suitable for a five-year-old, clearly celebrate a birthday, and contain no invented personal details about the child.

## Scope and given facts

In scope:

- The subject is a birthday celebration.
- The intended child is five years old.
- The requested deliverable is a song.
- The child’s name must remain a fill-in slot.
- The lyrics must be in English.
- The song should be original and suitable for a young child.

Out of scope:

- A biography of the child.
- A party itinerary, invitation, speech, or explanation of songwriting choices.
- Claims about the child’s personality, interests, family, location, appearance, or accomplishments.
- A melody copied from an existing song.
- Instructions requiring information that the user did not supply.

Use `[FILL IN: child’s name]` wherever the child’s name belongs. This slot is filled by replacing it with the child’s actual name before singing; do not replace it with a guessed name, a generic name, or a description. If a line becomes awkward after the name is inserted, preserve the slot and adjust only the surrounding original wording so the line remains singable.

## Working rules

Write an original lyric rather than reproducing or closely imitating any existing song, melody, lyric, artist, or recognizable copyrighted phrase. Use short, concrete vocabulary that a five-year-old can understand and repeat. Prefer joyful birthday imagery such as singing, dancing, candles, smiles, friends, family, and celebration, but include only generic imagery because no personal facts were provided.

Keep the emotional register affectionate and celebratory, never frightening, sarcastic, embarrassing, romantic, or mature. Do not mention age-related judgments, weight, appearance, behaviour problems, or family circumstances. Do not imply that the child owns particular objects, likes particular activities, or has achieved anything unless the user supplies that fact.

If the name slot is used in a line, make the surrounding syntax work with a name of varying length. If the slot would make the rhythm difficult, place it in a repeated refrain or a line with flexible syllable count rather than inventing a shorter form. If a rhyme would require an unsupported personal detail, choose a simpler rhyme or no rhyme; do not fill the gap with fiction.

Use a singable rhythm with repeated phrases and a memorable refrain. Keep the lyrics concise enough for a young child to follow. Do not provide musical notation, chord progressions, production directions, or a full melody unless requested.

## Output structure

Provide the song in this order:

1. **Title** — one short, cheerful title that does not invent the child’s name.
2. **Verse 1** — four short lines introducing the birthday celebration.
3. **Chorus** — four to six lines, including `[FILL IN: child’s name]` at least once and a clearly repeated birthday sentiment.
4. **Verse 2** — four short lines extending the celebration with generic, child-appropriate imagery.
5. **Chorus** — repeat the same chorus verbatim so it can be learned easily.
6. **Optional outro** — two to four short lines only if needed to give the song a satisfying ending.

Use plain lyric formatting with section labels such as **Verse 1**, **Chorus**, **Verse 2**, and **Outro**. Keep most lines short and easy to sing. Make the total song approximately 24–40 lyric lines, excluding the title and section labels. Do not add commentary before or after the song.

## Style rules

Use a hybrid style: present the title and section labels in an itemized, clearly separated format, while writing the lyrics as short narrative song lines. Keep the register playful, affectionate, inclusive, and understandable to a five-year-old. Avoid clichés that feel impersonal or overblown, including generic claims that the child is “the best ever,” “a superstar” without context, or “growing up too fast.” Avoid scary, competitive, romantic, or adult-oriented birthday language.

## 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 rather than an invitation, speech, poem explanation, or party plan.
2. Confirm that the intended audience is a five-year-old child and that the vocabulary, emotional tone, and imagery are age-appropriate.
3. Confirm that `[FILL IN: child’s name]` remains visibly unresolved wherever the child’s name is needed.
4. Confirm that the child’s name has not been replaced with an invented name, nickname, personal trait, location, hobby, family detail, or accomplishment.
5. Confirm that the song is original and does not reproduce an existing melody, lyric, artist’s style, or recognizable copyrighted phrase.
6. Confirm that the chorus is clearly marked and repeated verbatim if the requested structure includes a repeated chorus.
7. Confirm that the lyrics are easy to sing, with short lines, repeated language, and no unnecessarily complex vocabulary.
8. Confirm that the song contains no unsupported claims about the child beyond the supplied fact that the child is five years old.
9. Confirm that no unresolved slot was filled arbitrarily: the only personal-information slot in this request is `[FILL IN: child’s name]`.
10. Confirm that the response stays within scope: title, song sections, lyrics, and no unrelated explanation or production material.
11. Confirm that the final output is entirely in English and follows the hybrid formatting rule.
12. Before delivery, remove any line that introduces a fact not grounded in the user’s request or in generic birthday context.
