De-AI writing skill for any Agent Skills-compatible agent (77+ via the Skills CLI), with native plugins for Claude Code, Codex, Grok Build, and Antigravity. Narrative-architecture repair for fiction, venue-matched rules for professional prose. Based on StoryScope (arXiv:2604.03136).

About the project

sepia is an Agent Skill that revises AI-written fiction and professional documents to address structural patterns that can make them appear machine-generated. It is for agents that write, review, refactor, or recreate text, with different rules for fiction and document types.
