Covers OAuth setup, discovering the blog ID, writing Blogger-safe HTML, and auto-publishing. ## When to use - User wants to share a program/project on their Google blog - User wants an article, review, or analysis post written for the blog (model reviews, tech news, comparisons) - "자동발행" (auto-publish) or "블로그에 올려줘" / "블로그글로 써" requests - Writing styled HTML that must survive Blogger's sanitizer ## OAuth setup (one-time) Requires the `google-workspace` skill's setup.py for client-secret storage, but Blogger needs its OWN scope. Two paths: ### Path A — manual code copy (FRAGILE, avoid) `setup.py --auth-url` prints an auth URL; user authorizes, gets redirected to `localhost:1` (ERR_UNSAFE_PORT — normal), copies `code=` from the address bar, pastes back via `setup.py --auth-code`. **PITFALL:** auth codes expire in ~minutes. Users routinely take too long copying from a screenshot → `invalid_grant` on token exchange. If it fails twice, switch to Path B immediately. ### Path B — local HTTP server auto-capture (PREFERRED) Run a script that starts a local HTTP server on a real port (e.g. 8765), opens the browser with `redirect_uri=http://localhost:8765`, captures the code automatically on callback, and exchanges it. No copy-paste, no expiry race. See `scripts/google-auth-auto.py`. Both paths need: 1. Google Cloud project + **Blogger API enabled** 2. OAuth client (type **Desktop app**) → client_id + client_secret 3. **Test users** must include the user's Google account while app is in "Testing" (https://console.cloud.google.com/auth/audience) — otherwise "Access blocked: app has not completed verification" / not-a-test-user errors. ## Discover the blog ID ```python GET https://www.googleapis.com/blogger/v3/users/self/blogs Authorization: Bearer ``` Returns `items[].id` and `items[].url`. Don't guess the blog ID from the URL — query it. ## Publish a post ```python POST https://www.googleapis.com/blogger/v3/blogs/{blog_id}/posts/ Authorization: Bearer Content-Type: application/json {"title": "...", "content": "", "labels": [...], "status": "LIVE"} ``` Response `url` is the live post link. `status: "LIVE"` publishes immediately; `"DRAFT"` stages it. - **Match the blog's existing label taxonomy (hit 2026-08-07)**: before publishing a follow-up/related post, fetch an existing post on the same topic via `GET /blogs/{id}/posts/bypath?path=/YYYY/MM/.html` and reuse its `labels` array instead of inventing new ones (e.g. the URXR vs Quest 3 comparison reused the URXR intro post's `['킥스타터','하드웨어','XR']`). Keeps category feeds consistent. ## Blogger-safe HTML (CRITICAL) Blogger's sanitizer **strips `
