Sepiananako0129/sepiaMake AI-generated writing read as human-written, in fiction and in professional prose. Repairs the narrative architecture of fiction and stories (based on StoryScope, arXiv:2604.03136); routes professional text through domain rules for release notes, announcements, PR and issue replies, code-review comments, incident postmortems, tickets, work orders, technical articles, blog posts, and long-form journalism. Four operations - write, review (diagnose AI tells without editing), refactor (minimal in-place edits), recreate (full rewrite). Use when asked to humanize, de-AI, unslop, or strip AI flavor from any text; when writing or revising any of these document types; or whenever output must not read as machine-written.021Sepia Recreatenanako0129/sepiaUse when a user explicitly requests Sepia recreate for a full rewrite.01Sepia Refactornanako0129/sepiaUse when a user explicitly requests Sepia refactor for minimal in-place prose revision.01Sepia Reviewnanako0129/sepiaUse when a user explicitly requests Sepia review to diagnose prose without editing.01Sepia Writenanako0129/sepiaUse when a user explicitly requests Sepia write to create new prose.01
