User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
2. Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
3. Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.

Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.

Language

Respond in the user's language. If they write in Chinese, reply in Chinese; if English, English. Keep technical tokens (paths, flags, field names) in English.

Script Directory

{baseDir} = this SKILL.md's directory. Resolve ${BUN_X}: prefer bun; else npx -y bun; else suggest brew install oven-sh/bun/bun.

Preferences (EXTEND.md)

Check these paths in order; first hit wins:

Found → read, parse, apply. Not found → run first-time setup (references/config/first-time-setup.md) before anything else.

Minimum keys (case-insensitive, accept 1/0 or true/false):

Recommended EXTEND.md:

default_theme: default
default_color: blue
default_publish_method: browser
default_author: 宝玉
need_open_comment: 1
only_fans_can_comment: 0
chrome_profile_path: /path/to/chrome/profile

# Remote API publishing (optional) — only set if WeChat's IP allowlist
# excludes your local machine. See "Remote API Method" below.
# remote_publish_host: server.example.com
# remote_publish_user: deploy
# remote_publish_port: 22
# remote_publish_identity_file: ~/.ssh/id_ed25519
# remote_publish_known_hosts_file: ~/.ssh/known_hosts
# remote_publish_strict_host_key_checking: accept-new
# remote_publish_connect_timeout: 10
# remote_publish_proxy_jump: bastion.example.com

Raw ssh / scp options are intentionally not supported; only the typed keys above are honored. Authentication is SSH key only (no passwords).

Theme options: default, grace, simple, modern. Color presets: blue, green, vermilion, yellow, purple, sky, rose, olive, black, gray, pink, red, orange (or hex).

Value priority: CLI args → frontmatter → EXTEND.md (account-level → global) → skill defaults.

Multi-Account Support

EXTEND.md supports an accounts: block for managing multiple Official Accounts. With 2+ entries, the workflow inserts a Step 0.5 to prompt for account selection (or auto-selects based on default: true or --account <alias>).

Full details — compatibility rules, per-account keys, credential resolution, per-account Chrome profiles, CLI usage — in references/multi-account.md.

Pre-flight Check (Optional)

Before first use, suggest the environment check (user can skip):

${BUN_X} {baseDir}/scripts/check-permissions.ts

Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, API credentials, Chrome conflicts.

Image-Text Posting (图文)

Short posts with multiple images (up to 9):

${BUN_X} {baseDir}/scripts/wechat-browser.ts --markdown article.md --images ./images/
${BUN_X} {baseDir}/scripts/wechat-browser.ts --title "标题" --content "内容" --image img.png --submit

Details: references/image-text-posting.md.

Article Posting Workflow (文章)

- [ ] Step 0: Load preferences (EXTEND.md)
- [ ] Step 0.5: Resolve account (multi-account only — see references/multi-account.md)
- [ ] Step 1: Determine input type
- [ ] Step 2: Select method and configure credentials
- [ ] Step 3: Resolve theme/color and validate metadata
- [ ] Step 4: Publish to WeChat
- [ ] Step 5: Report completion

Step 0: Load Preferences

Check and load EXTEND.md (see "Preferences" above). If not found, complete first-time setup before any other questions. Resolve and cache for later steps: default_theme, default_color, default_author, need_open_comment, only_fans_can_comment.

Step 1: Determine Input Type

Plain-text handling:

1. Generate slug (first 2-4 meaningful words, kebab-case; translate Chinese to English for the slug).
2. Save to post-to-wechat/YYYY-MM-DD/<slug>.md (create directory if needed).
3. Continue as a markdown file.

Step 2: Select Publishing Method and Configure

Ask method unless specified in EXTEND.md or CLI:

API selected + missing credentials → run guided setup per references/api-setup.md (writes to .baoyu-skills/.env).

remote-api method: WeChat's "公众号设置 → IP 白名单" often limits API access to one or two fixed IPs. If your local machine's IP is not on that list but a cloud server's is, use remote-api: all markdown rendering, image processing, draft assembly, and HTML rewriting still happen locally, and only the outbound HTTPS calls to api.weixin.qq.com (token, uploadimg, add_material, draft/add) are tunneled through an SSH SOCKS5 dynamic port forward (ssh -N -D) so that WeChat sees the remote server as the source IP. No files are written to the remote host; AppSecret never leaves the local process. Requires only sshd and outbound network on the remote host — no Python, no agent process. See "Remote API Method" below.

Step 3: Resolve Theme/Color and Validate Metadata

1. Theme: CLI --theme → EXTEND.md default_theme → default (first match wins; do NOT ask if resolved).
2. Color: CLI --color → EXTEND.md default_color → omit (theme default applies).
3. Validate metadata (frontmatter for markdown, meta tags for HTML):
