openwriter

Orchestration skill for book-scale long-form writing (fiction or nonfiction). Owns the SHAPE of a book project — chapter architecture, beats methodology, workspace management, book mode, scene/science split, vignette library, long-form orchestration. Delegates VOICE (prose generation) to /authors-voice via the Apply Protocol minion dispatch. Loads as governing context at session start when a book project is detected, OR via explicit invocation. Use when: "/book-writer", "/book", "write a book", "book project", "chapter beats", "chapter architecture", "beat map", "TOC", "table of contents", "book outline", "book reshape", "draft a chapter", "long-form", "multi-chapter", "book mode", "book workspace", any work involving multi-chapter book structure. NOT for: single-chapter essays, blog posts, tweets — those go to /authors-voice directly. Voice-only setup (anchor blend, NEVER rules, fingerprints, corpus analysis) lives in /authors-voice.

OpenWriter — the writing surface for AI agents. A markdown-native rich text editor where agents write via MCP tools and users accept or reject changes in-browser. 40 core MCP tools for document editing, multi-doc workspaces, and organization, plus 21 publish platform tools for newsletter, social posting, and scheduling. Tweet compose mode for drafting replies/QTs with pixel-accurate X/Twitter UI. Plain .md files on disk — no database, no lock-in. Use when user says: "open writer", "openwriter", "write in openwriter", "edit my document", "review my writing", "check the pad", "write me a doc", "compose tweet", "reply to tweet", "quote tweet", "author's voice", "authors voice", "voice plugin". Requires: OpenWriter MCP server configured. Browser UI at localhost:5050.

Author's Voice — constructed-voice skill. Anchors writing to a training-data author blend, progressively layers NEVER rules, presentation fingerprints, sentence stats, coined terms, and curated examples from a growing local corpus. Pure markdown, opus sub-agent (the minion) writes prose. Use when: "/authors-voice", "/writers-voice", "set up my voice", "anchor my voice", "voice match", "use my voice", "write in my voice", "add to my voice profile", "voice profile status", "voice status", "authors voice", "writer's voice". API path (plugin / programmatic flows): see `docs/api/` for the rewrite + generate endpoints, MCP tools, setup, and troubleshooting. The local skill body below is the default; the API is one access point among others.

Channel-master writer for email newsletter. Weekly pipeline: scaffold structure, gather data, query the author, synthesize in their voice, review, send. Companion doc workflow. Voice-matched via the authors-voice skill. Works for any behind-the-scenes weekly newsletter built on proven content. Use when: "/newsletter-writer", "newsletter", "draft newsletter", "scaffold newsletter", "newsletter gather", "newsletter review", "newsletter send", "newsletter status", "newsletter to blog", "convert newsletter". Requires: OpenWriter MCP server configured.

Channel-master writer for long-form blog posts. Owns the SHAPE of a post — beat structure, title/preview/slug commitments, per-post container layout, per-site voice anchor discovery — and delegates VOICE (prose generation) to /authors-voice and PUBLISH mechanics to the openwriter github plugin (`add_blog_site` + `post_to_blog`). Use when: "/blog-writer", "write a blog post", "blog draft", "brainstorm blog topics", "blog beats", "extract beats from this post", "write about this feature", "draft a post", "blog title", "preview text", "OG description", "blog image", "featured image", "OG image", "integrate", "create the files", "wire up the blog post", "publish to blog", "post to blog", "set up blog repo", "register blog site". Requires: OpenWriter MCP server configured + github plugin enabled + `gh auth login` set up locally. Project SHOULD have a `## Blog` section in its CLAUDE.md for writing-rules / image-style overrides (optional after setup).

Anti-AI detection pass for any written text. Hard rules that strip the statistical fingerprints AI writing leaves behind — em-dash density, contrastive formula ("not X, it's Y"), nuclear phrases, copula inflation, sycophantic filler, uniform contractions, colon overuse, register monotony. Two tiers: hard rules (always fix) and voice-gated checks (verify against voice profile if present). Use when: "/anti-ai", "anti-ai pass", "anti-ai check", "strip ai signals", "does this sound like ai", "ai detection check", "humanize this", "remove ai fingerprints".

Channel-agnostic writer for any piece of content that doesn't yet belong to a specific channel. Use when you have something to say but don't know where it goes — could become a blog post, X thread, newsletter section, web copy, journal entry, or just stay as a plain doc. Runs the beat extraction + shaping discipline, pours prose via /authors-voice (with the operator's default anchor — personal voice), polishes, and leaves a clean draft in OpenWriter. The draft can later be refactored into a specific channel via /blog-writer, /x-writer, or /newsletter-writer. Use when: "/beat-writer", "write this", "draft something", "I have an idea but don't know where", "extract beats", "write me a draft", "pour this in voice", "I want to think this through in writing", "plain doc", "just open a doc", "uncommitted draft", "I'll figure out where it goes later". NOT for: known-channel work (use the channel-master directly — /blog-writer for blogs, /x-writer for tweets, /newsletter-writer for emails, /book-writer for chapters

Polish copy to 90/100. Channel the top 10 advertising practitioners in history. Score, rewrite, score again. Don't stop until 90%. Use when: "/polish", "polish this", "polish", "rewrite this", "improve this copy", "make this better", "score my copy"
