Xiaohongshu Auto-Posting (XHS Auto-Posting)

End-to-end Xiaohongshu content operation: topic discovery → style reference → writing → publishing → performance tracking.

Language

All process output to user (progress updates, questions, status notifications) follows the user's language.

Objective

Automate a complete Xiaohongshu content operation cycle for a configured product: discover high-engagement pain-point topics via search, collect writing style references, generate platform-native content aligned with the style fingerprint, publish with user approval, and track post-publish performance metrics.

Prerequisites

• Xiaohongshu creator center (creator.xiaohongshu.com) already logged in on a configured stealth browser (browser ID stored in session_state.json)
• workspaces/xhs-posting/ workspace (auto-created on first run)

Pre-execution Checks

1. Tool Readiness

If browser-act has been confirmed available in the current session → skip this step.

Invoke browser-act via Skill tool to load usage. If installation or configuration issues arise, follow its guidance to resolve then retry.

2. Login Verification

Covered in Phase 0.5 — login check is deferred until session state is loaded (Phase 0.2) and the browser is opened. If the user triggers Phase 6 directly (standalone tracking mode), still complete Phase 0.2 and Phase 0.5 first.

3. Session Lifecycle

Each execution generates a unique session name (xhs-<YYYYMMDD>-<HHMM>) to avoid cross-conversation conflicts. The session is opened once in Phase 0.5 and closed at the end of the workflow. All commands in this Skill reference the session via $SESSION — the actual name is determined at runtime.

---

Runtime Workspace

All runtime files (config, drafts, publish records, screenshots) are written to the user's working directory (CWD) under workspaces/xhs-posting/. This directory is auto-created on first run.

Quick Start

/xiaohongshu-auto-posting

Standalone triggers (jump directly to the corresponding phase, skipping Phase 0–4):

• "track performance" / "see data" / "data collection" → Phase 6 performance tracking
• "settings" / "switch account" / "update keywords" → Phase 0 configuration wizard

---

Operational Rules

Three rules that apply to every browser-act session. Violating any one causes silent failures or long hangs. Full details in references/phase5-publish.md §0.

Rule 1 — Never pipe browser-act output directly

Redirect state output to a temp file, then grep the file. Piping may background the command when output contains multi-byte characters, making the result unavailable synchronously.

# WRONG
browser-act --session $SESSION state | grep "Publish"
# CORRECT
browser-act --session $SESSION state > /tmp/s.txt 2>&1 && grep "Publish" /tmp/s.txt

Rule 2 — Escape all non-ASCII content before passing to eval --stdin

Non-ASCII literals (Chinese, emoji) in JS source cause encoding errors in the subprocess pipeline. Escape to \uXXXX first:

def to_ascii_js(s):
    return ''.join(r'\u{:04x}'.format(ord(c)) if ord(c) > 127 else c for c in s)
js = to_ascii_js(open('tmp/script.js', encoding='utf-8').read())
subprocess.run([..., 'eval', '--stdin'], input=js.encode('ascii'), ...)

Rule 3 — Use click, not eval, for actions that trigger navigation

eval hangs (~30 s timeout) when the callback causes a page redirect. Always use browser-act --session $SESSION click <index> for the publish button, then verify the URL immediately after.

Phase 0 — Initialization

0.1 Tool Check

Run browser-act browser list:

• Command not found → run uv tool upgrade browser-act-cli || uv tool install browser-act-cli --python 3.12, then continue
• Returns normally → continue

0.2 Session State Load

Read workspaces/xhs-posting/session_state.json:

• File does not exist, or browser_id is empty → proceed to 0.3 First-time Configuration Wizard
• File exists and browser_id is non-empty → load and display current config, ask user to confirm or modify

session_state.json structure:

{
  "browser_id": "",
  "account": {
    "nickname": "",
    "profile": ""
  },
  "product": {
    "name": "",
    "tagline": "",
    "url": "",
    "install_cmd": ""
  },
  "keywords_file": "workspaces/xhs-posting/config/keywords.json",
  "posting": {
    "daily_limit": 1,
    "min_interval_hours": 6,
    "last_posted_at": null
  }
}

0.3 First-time Configuration Wizard (when file does not exist or browser_id is empty)

Step 1: Browser Selection

Run browser-act browser list, then:

When existing browsers are present: display all browsers (id / name / type / desc / proxy), ask the user which one to use for posting:

Existing browsers:

#1  id=xxx  name="xxx"  type=stealth  desc="xxx"  proxy=XX
#2  id=xxx  name="xxx"  type=chrome   desc="xxx"

Select a browser number to use for posting, or enter "new" to create one:
>

When no browsers exist, or user enters "new":

1. Load advanced guide: browser-act get-skills advanced
2. Ask the user:
   • Browser name (custom, e.g. "xhs-poster")
   • Proxy requirements (needed? region or custom URL?)
3. Create the browser following the advanced guide's Confirmation Gate protocol
4. Record the new browser ID, continue to Step 2

Step 2: Product & Keyword Configuration

Ask the user:

1. Product name (brand keyword, used in tags and body)
2. Product tagline (one-sentence description)
3. Product URL (website / GitHub / App Store, etc.)
4. Install / usage command (optional; for SaaS products, enter the core operation path)
5. Initial keywords (1–5, comma-separated, used for topic search)

Write to workspaces/xhs-posting/session_state.json and workspaces/xhs-posting/config/keywords.json, then continue to Phase 0.4.

0.4 Account Safety Check

• Read posting.last_posted_at from session_state.json
• If less than min_interval_hours have passed since the last post, notify the user and ask whether to force continue
• If today's post count ≥ daily_limit, notify the user

0.5 Browser Launch & Login Verification

Generate a unique session name for this execution:

$SESSION = "xhs-<YYYYMMDD>-<HHMM>"   # e.g., xhs-20260611-1430

Open the browser using the stored browser_id:

browser-act --session $SESSION browser open <browser_id> https://creator.xiaohongshu.com/new/home
browser-act --session $SESSION wait stable

Verify login: check that the current URL stays on creator.xiaohongshu.com (not redirected to the login page) and that a user avatar / nickname element is present in state.

• Not logged in → instruct the user to scan the QR code in --headed mode:

  browser-act --session $SESSION browser open <browser_id> https://creator.xiaohongshu.com/new/home --headed
  

  Wait for the user to confirm login, then continue.

Phase 1 — Pain-Point Topic Collection

Full execution parameters: references/phase1-topic-collection.md.

Overview:

1. Keyword rotation: read the next keyword from config/keywords.json (sequential mode)
2. XHS search: search the keyword, sort by hottest, collect metadata for the top 10–15 notes
3. Listing Pass: extract shallow fields directly from search results (title, likes, collects, comments, snippet)
4. Engagement scoring: score = likes + collects × 2 + comments × 1.5
5. Top 5 Deep: click into the top 5 notes and extract deep fields (key quote, pain description, topic tags)
6. Generate report: output workspaces/xhs-posting/<date>/topics/TOPICS_<kw-slug>.md
7. Display Top 5 and wait for user selection

---

Phase 2 — Top Case Collection (Style Reference)

Full execution parameters: references/phase2-case-collection.md.

Overview:

1. Use the same search results as Phase 1; no additional request needed
2. Collect full text from the top 3 high-engagement notes (title + body + tags)
3. Analyze writing style: opening type, paragraph rhythm, emoji density, topic tag strategy
4. Generate Style Fingerprint
5. Write style fingerprint to workspaces/xhs-posting/<date>/style_fingerprint.json

Phase 2 runs in parallel with Phase 1 (shared search results, different analysis angle).

---

Phase 3 — Topic Selection

After displaying the Phase 1 Top 5, ask the user:

Here are the Top 5 topics. Which ones do you want to write?
(enter numbers like "1 3"; "all" for all; "skip" to pass today)
>

On receiving the reply:

1. Write the selected topic list to workspaces/xhs-posting/<date>/selected_topics.json
2. For each selected topic, confirm the publish strategy (publish now / save as draft)

If the user enters "skip" → end this run without advancing last_index.

---

Phase 4 — Content Writing

Full writing guidelines: references/phase4-writing.md.

Write one draft per selected topic, show a preview after each draft and wait for user approval before moving to the next.

Writing framework: Pain resonance → Struggle / attempts → Product discovery → Concrete proof → Call to action

Hard requirements:

• Title ≤ 20 characters (must use native setter when writing; see references/phase5-publish.md §5)
• Body ≤ 1000 characters, clear paragraphs
• Topic tags: 3–5, covering keyword + product brand + scene term
• Must include a closing CTA (comment / save / follow)

Pre-Write Gate (confirm all items before writing begins):

1. key_quote extracted from Phase 1 deep pass
2. pain_description confirmed from Phase 1
3. tools_tried confirmed from Phase 1
4. Product info (name, install command) read from session_state.json
5. Style fingerprint (style_fingerprint.json) read

After writing, generate an HTML preview (see references/phase4-writing.md §7), display it in the conversation, then ask:

Preview above. Ready to publish?
- "ok" / "publish" — proceed to Phase 5 publishing
- "edit: <instruction>" — revise per instruction and re-preview
- "draft" — save as draft, do not publish

---

Phase 5 — Publishing

Full execution parameters: references/phase5-publish.md.

Overview:

1. Image generation: use XHS Creator Center's built-in "Text-to-Image" feature to auto-generate a cover (recommended), or read a user-provided local image
2. Image upload (external image): two-step upload — GET permit → PUT file — to obtain file_id
3. Content Verification Gate: title ≤ 20 characters, body non-empty, topic tags present
4. Fill Creator Center: navigate → paste content → add topics → set cover
5. Publish: click the "Publish" button
6. Capture publish URL: extract note_id from the redirect URL or page
7. Write record: update workspaces/xhs-posting/<date>/published.json, update posting.last_posted_at in session_state.json

Gate: publish only executes after user approval of the content; auto-publishing unapproved content is not allowed.

---

Phase 6 — Performance Tracking

Full execution parameters: references/phase6-tracking.md.

Standalone trigger: when the user says "track performance" / "see data" / similar trigger words, jump directly to this phase.

Sub-actions:

Sub-action	Trigger	Description
6.1 Single post 24h tracking	Auto-scheduled after Phase 5 publish	Revisit note_id 24h later, update initial metrics
6.2 Batch data collection	User trigger / weekly	Pull latest data for all published notes from recent N days
6.3 View comments	User trigger	View new comments, draft replies, reply after user approval
6.4 Generate report	User trigger	Aggregate data, output table report

Data stored locally in workspaces/xhs-posting/tracking/.

---

Account Safety Rules

1. Posting frequency: ≤ 1 post per account per day, ≥ 6 hours between posts
2. Content originality: before each publish, check title similarity against historical posts (simple character-level check to avoid exact duplicates)
3. Avoid sensitive terms: body and title must not contain WeChat IDs, Weibo handles, contact info, or external links
4. No artificial engagement: do not simulate batch likes / collects / comments
5. Topic tags: use existing platform topics only; do not create new ones
6. Image compliance: use XHS built-in generated images or self-owned copyright images; do not use screenshots from others

---

Success Criteria

• Phase 1: candidates >= 10, deep-extracted notes = 5, report file exists
• Phase 2: style_fingerprint.json written, sample_notes count >= 1
• Phase 4: user explicitly approves draft content
• Phase 5: redirect URL contains published=true, note_id captured and written to published.json
• Phase 6: all tracked note metrics updated without error

Session Cleanup

After completing the workflow (any phase exit — normal completion, user abort, or error), close the session to release resources:

browser-act session close $SESSION

Do not close if the user explicitly requests to keep the session open for manual inspection.

---

Known Limitations

• Max 1 post per account per day; minimum 6-hour interval enforced
• window.__INITIAL_STATE__ hydration timing is inconsistent — retry once after 2 s if empty
• search/notes XHR may not appear in all browser fingerprints; fall back to get markdown if missing
• Topic chip insertion silently fails after execCommand body injection — always embed hashtags directly in body text (see references/phase5-publish.md §4.3)
• note_id may not be auto-capturable when note is under review; record as pending_review and fill in manually later

Experience Notes

Path: {working-directory}/browser-act-skill-forge-memories/xiaohongshu-auto-posting-xhs-post.memory.md

Before execution: if the file exists, read it first — it records unexpected situations encountered during past executions (e.g., a strategy has become ineffective); adjust strategy accordingly.

After execution: if an unexpected situation is encountered (strategy became ineffective, page redesigned, anti-scraping upgraded, better path discovered), append a line: {YYYY-MM-DD}: {what happened} → {conclusion}

Normal execution does not write to the file. Do not record which keywords were used or how many results were returned — those are task outputs, not experience.
