Juejin Publisher

Juejin Publisher

Prepare or publish a reviewed Juejin article from the canonical repository source and choose appropriate technical categories and tags. A request to publish or a queue item marked 排队 authorizes the final action; do not ask again at the last button. Stop only for a draft or preview task.

Inputs

• Source Markdown path or topic.
• Intended title, language, and audience, if specified.
• Optional cover, category, tags, source URL, GitHub link, or paper link.

If the source path is missing, inspect .github/publisher/posts_queue.txt, .github/publisher/media/not-published.md, and recent docs/blog/posts/ entries before asking the user.

Platform Entry Points

• Editor: https://juejin.cn/editor/drafts/new
• Observed profile: https://juejin.cn/user/4288563097635144
• Observed article list: https://juejin.cn/user/4288563097635144/posts

Use a browser surface with the logged-in session when UI work is required. For the maintained yunwei37 account, prefer the existing Chrome Yunwei profile, which carries the verified Juejin login. A fresh in-app browser session may be logged out; do not treat that state as evidence that the account itself is unavailable. Confirm the avatar and creator controls on the visible page before proceeding. Never bypass authentication with search results or alternate sources.

References

Load references/platform-preferences.md when choosing Juejin-native framing, category/tags, tutorial-vs-series shape, or promotion/link balance.

Browser-Only Platform Boundary

Do not directly access Juejin APIs, internal endpoints, or background HTTP interfaces under any circumstances. All verification, drafting, QA, screenshots, and ledger evidence must come from normal browser interactions that a regular logged-in user can perform: navigating pages, scrolling profile/article lists, clicking visible controls, reading rendered page content, using the editor UI, and capturing screenshots.

Draft Preparation

1. Read the canonical Chinese source and extract title, summary, tags, images, code blocks, source URL for the ledger, GitHub links, and paper links.
2. Build a Juejin copy in canonical syndication mode:
   • remove YAML front matter
   • remove the source H1 because the Juejin title field renders the article title; confirm the preview does not repeat it
   • preserve the article body by default
   • convert relative images to checked public URLs or prepare editor upload
   • ensure code fences have language labels
   • preserve the source title exactly
   • preserve links already present in the source
3. Keep the opening, section order, claims, examples, and conclusion unchanged. If the source needs a content fix, update it first or skip syndication. Rewrite, translate, shorten, expand, reorder, or split only when the user explicitly asks for that specific publication.

Draft Archive

Before opening the Juejin editor, write or update the Juejin draft record under draft/media/YYYY-MM-DD/<source-slug>/juejin.md using the local date. For unchanged Chinese canonical syndication, the file may reference the source body instead of duplicating it, but it must record the exact title, source URL for the ledger if known, GitHub/paper links, category/tags, source/project note if useful, media choices, and QA state.

Editor Workflow

When resuming an interrupted publish, first inspect the normal visible authored profile for the exact title and source identity. The final submission may have succeeded before the parent task stopped. If the article is already public, do not reopen a new draft or submit again; verify the public page and reconcile the artifact, ledger, queue, and snapshots instead.

1. Open https://juejin.cn/editor/drafts/new.
2. Fill the title field, observed as 输入文章标题....
3. For long-form posts, finish the Juejin-specific Markdown artifact locally before opening the editor. Paste or import that final artifact; do not use the platform editor for large rewrites or link-heavy tail-note repair. When repairing an existing article, verify that the editor replaced the old body instead of appending another copy. After saving, confirm on the public page that the opening paragraph, first section, and references each occur only once. Repair the same article if duplication appears; never republish it as a new post.
4. Use 预览 to scan headings, images, links, code blocks, and table layout.
5. Click 发布 only to inspect publish settings when needed.
6. Choose category and tags carefully:
   • eBPF tutorials: 后端, Linux, 开源, 云原生, 架构
   • AI agent or runtime posts: 人工智能, AIGC, 后端, 架构, 安全
   • GPU observability posts: 人工智能, 后端, 架构, Linux, 性能优化
   • The tag field is a search-select widget that exposes only a curated option list; not every intended tag is offered, and typing a term can commit an unrelated suggestion. For the 2026-09-12 48-energy tutorial, only Linux, 后端, and 性能优化 were available — eBPF and 开源 were not. Verify each tag chip by clicking 确定 (or the confirm control) one at a time, read the committed chips back, and record the actually-committed tags in the ledger rather than the intended list.
7. Complete 确定并发布 when the task requests publication or the queue item is marked 排队; do not ask for duplicate confirmation. Stop at preview only for a draft or preview task.

For images, verify the exact final URL used in Markdown before publishing. Do not assume imgs/... can be converted by guessing an eunomia.dev article path; that path may return 404. A public GitHub raw URL can also produce 转存失败，建议直接上传图片文件 in Juejin. When that happens, upload the source image through the visible editor, use the resulting Juejin-hosted URL in the local publishing copy, and confirm that the failure marker is gone and the rendered image has non-zero dimensions. Verify the same image again on the public page.

Session And Editor Recovery

• Environment restarts can drop the visible Chrome profile's Juejin login even though the profile directory and the mounted /run/social-manager-session/browser-state.json still hold valid Juejin session cookies (sid_tt, sessionid, sid_guard, uid_tt, n_mh, ...). Symptom: /editor/drafts/new redirects to /login, and the profile page shows no creator controls.
• agent-browser cookies set writes only non-httpOnly cookies on the current page and does not restore the session; the browser-target CDP Network.setCookies is not exposed here ('Network.setCookies' wasn't found). The reliable import is the page-target CDP domain Storage: Storage.setCookies with the cookie objects from the mounted state file, then verify with Storage.getCookies. This restores all httpOnly session cookies (55 cookies imported, 19 Juejin cookies observed on 2026-09-14).
• After import, the first navigation may hit a ByteDance 验证码中间页 (slide CAPTCHA) on the profile or editor URL. Do not solve the CAPTCHA. Re-navigating to / and then back to /editor/drafts/new cleared it on 2026-09-14, and the editor rendered with the title input and CodeMirror.
• Setting the body through document.querySelector('.CodeMirror').CodeMirror.setValue(...) requires an explicit UTF-8 decode. Passing atob(base64) directly yields mojibake (Latin-1 interpretation of UTF-8 bytes); decode with new TextDecoder('utf-8').decode(Uint8Array.from(atob(b64), c => c.charCodeAt(0))). Verify the resulting character count equals the local artifact byte-length in characters before submitting.

Content Strategy

Juejin-native short posts and new articles can use immediately useful technical framing. This guidance does not apply to syndicated long-form content. For an existing Chinese long-form eunomia.dev post, preserve the source title exactly and keep the body substantively unchanged. Only fix Markdown/rendering and set category, tags, cover, and summary metadata. Do not split a source article into a series by default.

Optimize for the maintainer's personal technical account brand and practical developer trust, not only for search ranking or traffic back to eunomia.dev. Preserve GitHub, tutorial, docs, or paper links already in the source. A visible eunomia.dev canonical/source note is optional and is not added to the body by default.

Safety Boundary

Do not automate:

• final 确定并发布 when the task is limited to a draft or preview
• direct Juejin API access, internal endpoint reads, or browser-hidden data fetches
• sign-in, phone verification, or CAPTCHA
• 去签到, likes, follows, comments, reposts, or private messages
• account settings or monetization settings
• deleting drafts

Ledger Update

After a confirmed publish, update .github/publisher/media/published.md with title, source path, Juejin URL, date, category, tags, and formatting fixes. Remove or update the matching row in .github/publisher/media/not-published.md.

Before closing the publishing task, run a platform-lessons pass. Add any new, reproducible editor failure and its verified workaround to this skill or its references so the next publish does not repeat it.

Keep screenshots and observed UI notes under .github/publisher/media/.
