Post to WeChat Official Account

Language

Match user's language: Respond in the same language the user uses. If user writes in Chinese, respond in Chinese. If user writes in English, respond in English.

Script Directory

Agent Execution: Determine this SKILL.md directory as {baseDir}, then use {baseDir}/scripts/<name>.ts. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun.

Working directory & paths:

• CLI/file paths (e.g. article.md, --cover cover.png) are resolved relative to the current working directory. To avoid path mistakes, prefer absolute paths, or run commands from the directory that contains your article and images.
• API credentials are loaded from environment variables first, then from {baseDir}/.env (skill root).

Script	Purpose
scripts/wechat-api.ts	Article posting via API (文章)
scripts/check-permissions.ts	Verify environment & permissions

Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

# macOS, Linux, WSL, Git Bash
test -f .config/baoyu-markdown-to-html/EXTEND.md && echo "project"
test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-markdown-to-html/EXTEND.md" && echo "user"

# PowerShell (Windows)
if (Test-Path .config/baoyu-markdown-to-html/EXTEND.md) { "project" }
$xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" }
if (Test-Path "$xdg/baoyu-markdown-to-html/EXTEND.md") { "user" }

┌────────────────────────────────────────────────────────┬───────────────────┐ │ Path │ Location │ ├────────────────────────────────────────────────────────┼───────────────────┤ │ .config/baoyu-markdown-to-html/EXTEND.md │ Project directory │ ├────────────────────────────────────────────────────────┼───────────────────┤ │ $HOME/.config/baoyu-markdown-to-html/EXTEND.md │ User home │ └────────────────────────────────────────────────────────┴───────────────────┘

┌───────────┬───────────────────────────────────────────────────────────────────────────┐ │ Result │ Action │ ├───────────┼───────────────────────────────────────────────────────────────────────────┤ │ Found │ Read, parse, apply settings │ ├───────────┼───────────────────────────────────────────────────────────────────────────┤ │ Not found │ Run first-time setup (references/config/first-time-setup.md) → Save → Continue │ └───────────┴───────────────────────────────────────────────────────────────────────────┘

EXTEND.md Supports: Default theme | Default color | Default author

First-time setup: references/config/first-time-setup.md

Minimum supported keys (case-insensitive):

Key	Default	Mapping
default_author	empty	Fallback for author when CLI/frontmatter not provided

Recommended EXTEND.md example:

default_theme: default
default_color: blue
default_author: 神刀墨客

Theme options: default, grace, simple, modern

Color presets: blue, green, vermilion, yellow, purple, sky, rose, olive, black, gray, pink, red, orange (or hex value)

Value priority:

1. CLI arguments
2. Frontmatter
3. EXTEND.md
4. Skill defaults

Pre-flight Check (Optional)

Before first use, suggest running the environment check. User can skip if they prefer.

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

Checks: Bun runtime, API credentials.

If any check fails, provide fix guidance per item:

Check	Fix
Bun runtime	brew install oven-sh/bun/bun (macOS) or npm install -g bun
API credentials	Follow guided setup in Step 2, or manually set in {baseDir}/.env

Article Posting Workflow (文章)

Copy this checklist and check off items as you complete them:

Publishing Progress:
- [ ] Step 0: Load preferences (EXTEND.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 settings (see Preferences section above).

CRITICAL: If not found, complete first-time setup BEFORE any other steps or questions.

Resolve and store these defaults for later steps:

• default_theme (default default)
• default_color (omit if not set — theme default applies)
• default_author

Step 1: Determine Input Type

Input Type	Detection	Action
HTML file	Path ends with .html, file exists	Skip to Step 3
Markdown file	Path ends with .md, file exists	Continue to Step 2
Plain text	Not a file path, or file doesn't exist	Save to markdown, continue to Step 2

Plain Text Handling:

1. Generate slug from content (first 2-4 meaningful words, kebab-case)
2. Create directory and save file:

mkdir -p "$(pwd)/post-to-wechat/$(date +%Y-%m-%d)"
# Save content to: post-to-wechat/yyyy-MM-dd/[slug].md

3. Continue processing as markdown file

Slug Examples:

• "Understanding AI Models" → understanding-ai-models
• "人工智能的未来" → ai-future (translate to English for slug)

Step 2: Select Publishing Method and Configure

This skill publishes to WeChat Draft Box via Official API.

Check API credentials:

Recommended: save credentials in {baseDir}/.env. The scripts will find it even when run from a subdirectory.

If Credentials Missing - Guide Setup:

WeChat API credentials not found.

To obtain credentials:
1. Visit https://mp.weixin.qq.com
2. Go to: 开发 → 基本配置
3. Copy AppID and AppSecret

Where to save?
A) Skill-level: {baseDir}/.env

After location choice, prompt for values and write to .env:

WECHAT_APP_ID=<user_input>
WECHAT_APP_SECRET=<user_input>

Step 3: Resolve Theme/Color and Validate Metadata

1. Resolve theme (first match wins, do NOT ask user if resolved):

   • CLI --theme argument
   • EXTEND.md default_theme (loaded in Step 0)
   • Fallback: default

2. Resolve color (first match wins):

   • CLI --color argument
   • EXTEND.md default_color (loaded in Step 0)
   • Omit if not set (theme default applies)

3. Validate metadata from frontmatter (markdown) or HTML meta tags (HTML input):

Field	If Missing
Title	Prompt: "Enter title, or press Enter to auto-generate from content"
Summary	Prompt: "Enter summary, or press Enter to auto-generate (recommended for SEO)"
Author	Use fallback chain: CLI --author → frontmatter author → EXTEND.md default_author

Auto-Generation Logic:

• Title: First H1/H2 heading, or first sentence
• Summary: First paragraph, truncated to 120 characters

4. Cover Image Check (required for API article_type=news):
   1. Use CLI --cover if provided.
   2. Else use frontmatter (coverImage, featureImage, cover, image).
5. Else fallback to first inline content image.
6. If still missing, stop and request a cover image before publishing.

Step 4: Publish to WeChat

CRITICAL: Publishing scripts handle markdown conversion internally. Do NOT pre-convert markdown to HTML — pass the original markdown file directly.

Markdown citation default:

• For markdown input, ordinary external links are converted to bottom citations by default.
• Use --no-cite only if the user explicitly wants to keep ordinary external links inline.
• Existing HTML input is left as-is; no extra citation conversion is applied.

API method (accepts .md or .html):

${BUN_X} {baseDir}/scripts/wechat-api.ts <file> --theme <theme> [--color <color>] [--title <title>] [--summary <summary>] [--author <author>] [--cover <cover_path>] [--no-cite]

CRITICAL: Always include --theme parameter. Never omit it, even if using default. Only include --color if explicitly set by user or EXTEND.md.

Note: --theme is required for Markdown input (it controls the markdown→HTML renderer). For HTML input, --theme is not needed.

draft/add payload rules:

• Use endpoint: POST https://api.weixin.qq.com/cgi-bin/draft/add?access_token=ACCESS_TOKEN
• article_type: news (default) or newspic
• For news, include thumb_media_id (cover is required)
• author resolution: CLI --author → frontmatter author → EXTEND.md default_author

If script parameters do not expose the two comment fields, still ensure final API request body includes resolved values.

Step 5: Completion Report

For API method, include draft management link:

WeChat Publishing Complete!

Input: [type] - [path]
Method: API
Theme: [theme name] [color if set]

Article:
• Title: [title]
• Summary: [summary]
• Images: [N] inline images
• Comments: [open/closed], [fans-only/all users]

Result:
✓ Draft saved to WeChat Official Account
