+# Editor Flow
+
+This skill is based on the preserved source flow in `assets/zhihu_write_flow.source.json`.
+
+## Entry Points
+
+- Creator center entry URL: `https://www.zhihu.com/creator`
+- BrowserAttached direct editor URL: `https://www.zhihu.com/creator/posts/new`
+
+`https://zhuanlan.zhihu.com/write` exists in the preserved source flow, but it is not the default entry point inside the current SuperRPA browser host because the host domain policy only guarantees `www.zhihu.com`.
+
+The current BrowserAttached flow enters creator center first, then uses the packaged browser-script tools to resolve whether the session is blocked by login, already in the editor, or needs the canonical creator editor route.
+
+## Required Inputs
+
+- `title`
+- `body`
+
+Both fields must be non-empty before any browser action starts.
+
+## Core Sequence
+
+1. Navigate to creator center.
+2. Click the write-article entry.
+3. Wait for the title input in the editor domain.
+4. Fill the title with `clear_first = true`.
+5. Fill the body editor with `clear_first = true`.
+6. If publish mode:
+   - scroll to the publish button
+   - click publish
+   - wait for publish confirmation dialog
+   - click confirm publish
+   - wait for published title
+   - verify published title text
+
+## Readiness Checks
+
+- The editor is considered ready only after the title input appears.
+- The publish flow is not complete until at least one post-publish verification succeeds.
+
+## URL Capture Rules
+
+- Pre-publish clicks may return an editor URL.
+- A valid published article URL should match the published article prefix and should not end in `/edit`.
+- If publish mode finishes without a published article URL, treat the run as unconfirmed even if some clicks succeeded.
+
+## Known Brittle Points
+
+- creator-center article entry selector
+- placeholder-based title input selector
+- generic primary-button publish selectors
+
+These should be revalidated before any live publish run.

+# Publish Safety
+
+Publishing is the highest-risk action in this skill. Treat it as a gated operation.
+
+## Mandatory Safety Rules
+
+- Do not publish without explicit human confirmation in the current conversation.
+- Do not assume `publish: true` in an old request still reflects the user’s latest intent.
+- Do not treat a successful click as proof of publication.
+
+## What Must Be Verified
+
+At least one of these post-publish checks should succeed:
+
+- the final URL is a published Zhihu article URL
+- the visible page title matches the requested article title
+
+If both checks fail, report the run as unconfirmed.
+
+## Failure Cases
+
+### Title verification fails
+
+- Stop.
+- Report the expected title and the observed title.
+- Do not claim the article was published correctly.
+
+### URL remains in edit mode
+
+- Treat the result as draft or unconfirmed publish.
+- Report that the browser stayed on an editor-style URL.
+- Ask for manual review before any retry.
+
+### Publish dialog does not appear
+
+- Do not retry blindly on generic primary buttons.
+- Report that the dialog selector failed.
+- Revalidate selectors and page state first.
+
+## Brittle Selectors To Revalidate First
+
+- `div.css-1q62b6s > div.css-byu4by`
+- `textarea[placeholder='请输入标题（最多 100 个字）']`
+- `button.Button--primary.Button--blue`
+- `div[role='dialog'] button.Button--primary.Button--blue`
+- `h1`
+
+These are usable as source references, but not trustworthy forever.
