Analyze [APPROVED WRITING SAMPLES] for [AUDIENCE]. State which samples you actually read. Identify recurring sentence patterns, level of detail, humor, vocabulary, ways of explaining steps, and calls to action.
Cite short examples for each observed rule. Separate observed habits from your recommended defaults. Describe what to avoid with concrete examples rather than vague labels. Do not invent my life story, customer results, beliefs, or offer terms from the writing style.
Return a compact voice guide, three practical do/don't pairs, and any conflicts between samples. Preserve the meaning of quoted text. The result should help another writer make a useful draft, not imitate every sentence mechanically.
