# Blog Writer Channel-master skill for long-form blog content. Owns ideation → beats → draft → image → publish. **Architecture:** beats-first (v0.5.0) + plugin-backed publish (v0.4.0). Each post lives in its own container with two sibling docs: a `Beats` doc (the structural commitments — beat list + title/preview/slug as B0) and a `Draft` doc (the voice-poured prose). Beats reshape regularly; draft re-pours via `/authors-voice` against a per-site anchor (`voice/anchor-<site-slug>.md`). Publish is a single `post_to_blog` MCP call against a site registered via `add_blog_site` — site-specific frontmatter (layout, author, prerender, `date → publishedDate` for Astro, etc.) lives on the github plugin's per-site config in `~/.openwriter/config.json`, not in project config. Mirrors book-writer's discipline at post scale. ## Convention This skill obeys the shared writer contract at [WRITER-CONVENTION.md](../WRITER-CONVENTION.md). Brief shape and return shape match that doc. Sub-form values: `long` | `short` | `tutorial` | `announcement`. **OpenWriter pad mechanics are canonical in [/openwriter](../openwriter/SKILL.md) — read it, don't re-derive from tool descriptions.** The load-bearing rule: `populate_document` is **create-only, used ONCE**; it re-sends the whole body, so calling it again to "fix" a doc appends a duplicate. All edits (rewrite / insert / delete) go through `write_to_pad` on fresh node IDs. Plus the read ladder (`outline_doc` → `search_docs` → `peek_doc` → `read_p...
