WHAT GETS EXTRACTED
The author.spec
object schema
"persona":{ role, authority, audience_model, expertise }
B2B practitioner. Technical reader assumed. No hype tolerance.
"voice":{ tone, rhythm, humor, hedging, register }
Direct. Dry humor. Short for impact, long for nuance.
"techniques":[ opening_pattern, evidence_count, closing_style ]
Opens with a concrete problem. 2–3 examples. Ends with action.
"example_phrases":"The real question is...", "Let me be specific."
Signature expressions extracted from your writing samples.
"avoid_patterns":"In conclusion,", "It is worth noting that"
Phrases that break your voice. Equally important.
+ MUCH MORE
These 5 sections are the output structure. Each section contains dozens of fine-grained parameters extracted specifically from your writing — writing_pace, argument_depth, topic_affinity, sentence_variance, contraction_rate, irony_markers, cultural_references and many others. The spec is yours and it reflects nobody else.
