openwriter skillA
openwriter is agent-read markdown (skill) from travsteward/openwriter: 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",.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add travsteward/openwriter/openwriter@v0.18.0mdr add travsteward/openwriter/openwriter@sha256:0c6c7a6f4e69e360Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
