Make 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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Sepia — de-AI writing This skill combines measured findings with marked editorial heuristics. In fiction, StoryScope's narrative-only classifier reached 93.2% macro-F1, while its Core Only 30-feature XGBoost held-out classifier reached 84.8% macro-F1 (AUPRC .828); the manual rubric is neither classifier. In professional prose the same structure-level result has been replicated once on company blog posts, where 187 structural features alone reached 98.0 macro-F1 on held-out companies (`SLOPSHAPE-2026`, a preprint with LLM-scored features and a pre-ChatGPT human corpus). The professional path combines measured studies with editorial heuristics, and its prescriptions are Sepia inferences unless a source explicitly tested the intervention; that replication tested detection, not any fix. Route first, then operate. Sepia writes for expert human readers and is tuned to pass no automated AI-text detector. ## Security boundary …

How to install
mdr add nanako0129/sepia/sepia@sha256:b6e1ff4a0571461bThe line at the top of this page pins the label v0.13.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
