Here are the “Style Mimic” prompts to run once and reuse forever:

1. Build my “Style DNA” from samples

Prompt:

"You are my Style Mimic analyst. Your job is to reverse-engineer my writing style from the samples I provide and produce a reusable style guide that another model can follow exactly.

Analyze the samples and output:

1. Style DNA (1 page max): tone, formality, warmth, directness, confidence, humor, length, pacing, sentence/paragraph structure.
2. Opening patterns: 5 greeting/opening templates I commonly use (with when to use each).
3. Closing patterns: 5 closing/sign-off templates (with when to use each).
4. Language fingerprint: common words/phrases I use, transitions, hedges I use or avoid, typical calls-to-action, how I ask questions.
5. Formatting rules: bullets vs paragraphs, punctuation habits, emoji use (or none), use of contractions, capitalization, subject line style.
6. Do/Don’t list: 10 things to do to sound like me, 10 things to avoid that would sound “off-brand.”
7. Response types: how I write (a) quick replies, (b) detailed replies, (c) declines, (d) follow-ups, (e) apologies, (f) scheduling.
8. Phrase bank: 25 ready-to-use sentences in my voice (categorized: agree/decline/ask/confirm/pushback/thanks).

Then create a final deliverable called “STYLE MIMIC SYSTEM PROMPT” that I can paste into another chat as the ongoing instruction set.

Constraints:

• Do not copy full sentences from samples verbatim unless they are short common phrases.
• If the samples contain conflicting styles, identify the main style and list optional variants.
• If anything is unclear, ask up to 3 targeted questions at the end."

1. Turn that into the reusable “Style Mimic” instruction (system prompt)

After Prompt 1, you’ll get a “STYLE MIMIC SYSTEM PROMPT.” If you want a stronger version, use this prompt to refine it:

Prompt:

"Improve the “STYLE MIMIC SYSTEM PROMPT” you just produced so it is:

• Strict (hard to drift from my voice)
• Practical (includes checklists and guardrails)
• Safe (never invent facts; flags missing info)
• Efficient (works for short replies and long replies)

Output only the upgraded “STYLE MIMIC SYSTEM PROMPT” with:

• A quick “voice checklist” (5 bullets)
• A “don’t break character” section
• A “when unsure” section (ask questions vs placeholders)"

1. Draft replies to an email thread in my voice (daily driver)

Use this each time you want a response drafted. Replace bracketed fields.

EMAIL THREAD (verbatim): [paste the email thread]

MY INTENT / OUTCOME: [what I want to achieve]

KEY FACTS (must be included):

DELIVERABLE:

1. Draft reply in my voice.
2. If helpful, provide an alternative version that is (a) shorter and (b) more assertive.
3. List any assumptions you had to make. If info is missing, use [NEEDS INFO: …] instead of guessing.
