WX Article Creator

Use this skill when the user asks to draft or create a Weixin official account article (plain text or Markdown) and submit it as a draft.

Inputs

• draft: User-provided draft text (plain or Markdown)
• title: Article title
• thumbmediaid: Weixin thumbnail media id for draft (optional, see Workflow)
• thumbimage: Path to thumbnail image file (optional, used if thumbmedia_id not provided)
• format: Optional enum (auto, markdown, plain)

Outputs

• markdown: Final markdown source
• html: Rendered HTML
• wxcli_result: Command output

Rules

• Do not invent wxcli commands; use README-documented format.
• Always ask for user confirmation before running wxcli.
• Render HTML using exactly:

npx markdown-to-html-cli --source <SOURCE.md> --style=./style.css

• CSS must be loaded from skills/wxarticle_creator/style.css.
• Preserve meaning; no new facts. Keep length within +/-10% when polishing.

Workflow

1. Detect input format.

- If format=auto, detect Markdown by headings (#), lists (-/1.), links, or code fences. - If Markdown is provided, keep it. - If plain text, convert it to Markdown with clear hierarchy.

1. Convert plain text to structured Markdown (if needed).

- Use the provided title as an H1. - Derive H2 sections from topic shifts or leading phrases. - Use H3 for subtopics, and bullet/numbered lists for enumerations. - Keep original ordering and meaning.

1. Polish Markdown lightly.

- Fix typos and improve readability. - Keep structure; do not add new facts.

1. Handle thumbnail (thumbmediaid):

- If thumbmediaid is provided: Use it directly. - If thumbimage is provided (path to image file): - Upload the image: wxcli material upload --type image --file "<thumbimage>" - Extract the returned mediaid from the output. - If neither is provided: - Get the latest image from materials: wxcli material list --type image --offset 0 --count 1 --json - Extract the mediaid from the first item. - If no images exist, inform the user and proceed without thumbmediaid.

1. Write Markdown source to a temporary file in a temp directory.

- Create a temp directory (e.g., /tmp/wxarticlecreator-<YYYYMMDD-HHMMSS>). - Save as <TMPDIR>/article-<YYYYMMDD-HHMMSS>.md (or another <SOURCE.md>). - Remove the temp directory after HTML is generated, unless the user requests it.

1. Convert Markdown to HTML with the CLI.

- Copy skills/wxarticle_creator/style.css into the temp directory as style.css. - Run the command from the temp directory so ./style.css resolves. - Command: npx markdown-to-html-cli --source <SOURCE.md> --style=./style.css - Capture stdout as HTML output. - Ensure the content is wrapped in <div id="nice">...</div> if it is not already, so the stylesheet applies.

1. User confirmation.

- Show polished markdown and a rendered HTML snippet. - If thumbmediaid was auto-fetched, mention which image is being used. - Ask: "Proceed to create Weixin draft with wxcli?"

1. Submit via wxcli.

- Include --thumb-media-id <thumbmediaid> only if available. - Direct content: wxcli draft add --title "<title>" --content "<html>" --thumb-media-id <thumbmediaid> - From pipeline: npx markdown-to-html-cli --source <SOURCE.md> --style=./style.css | wxcli draft add --title "<title>" --content - --thumb-media-id <thumbmediaid> - Return output to the user.

Failure Handling

• If thumbnail upload fails, show the error and ask to retry or proceed without thumbnail.
• If getting latest image fails, inform the user and proceed without thumbmediaid.
• If the CLI conversion fails, show the error and ask to retry.
• If wxcli fails, show the error output and ask whether to retry or adjust inputs.
