Obsidian to Weixin

Config (Optional)

Set a default author in ~/.agents/config.yaml:

obsidian_to_weixin:
  author: "Alice Wang"

You can also set a global default:

author: "Alice Wang"

Workflow (Sequential)

1. Resolve vault path and note path/title using obsidian-cli.
2. Read note file as Markdown (no Notion export/conversion).
3. Ensure author exists in front matter (and add visible byline if needed).
4. Upload note images to Weixin (material image) and replace Markdown image URLs.
5. Prepare thumbmediaid:

- Use the first image in note order as Weixin cover (material thumb). - If note has no image, fallback to the latest Weixin image material ID.

1. Generate digest with AI summarization (if user did not provide one).
2. Create Weixin draft from Markdown stdin via node-wxcli draft add --format markdown --css-path ....

Inputs (Ask if missing)

• note_path: Obsidian note path from vault root (recommended), e.g. Projects/Weekly Update.md.
• notetitle: title/name to search when notepath is missing.
• author: optional, fallback from ~/.agents/config.yaml.
• css_path: required when using --format markdown; if missing, default to assets/default.css.
• thumbmediaid: only needed if first-image + fallback both fail.
• digest: optional user-provided summary; if missing, generate via AI from the final Markdown.

Prerequisites

• obsidian-cli installed and default vault configured.
• node-wxcli installed and authenticated.
• curl + jq available.

Step 1: Resolve note from Obsidian

Get default vault path:

vault_path=$(obsidian-cli print-default --path-only)

If note_path is provided, use it directly.

If only note_title is provided, search candidates and confirm exact note:

obsidian-cli search "<note_title>"
obsidian-cli search-content "<note_title>"

Then resolve final path (from search result / user confirmation), and read file:

cat "$vault_path/<note_path>" > <workdir>/note.md

Step 2: Keep Markdown as source

Obsidian notes are already Markdown. Do not run any Notion export or Notion-to-Markdown conversion.

Step 3: Author handling

• If author is missing, read from ~/.agents/config.yaml.
• Ensure front matter contains author if your workflow requires it.

Step 4: Process images and replace URLs

Supported image references:

• Markdown image: ![alt](path-or-url)
• Obsidian embed: ![[image.png]]

Process in note order:

1. Parse image references from <workdir>/note.md.
2. Resolve each image file:

- local relative paths -> absolute file path (based on note dir/vault) - remote URL -> download to temp file

1. Upload to Weixin image material:

node-wxcli material upload --type image --file <image-file> --json | jq -r '.url'

1. Replace original image target with returned Weixin URL.
2. Rewrite ![[...]] to standard markdown image form:

![image](<weixin-url>)

Step 5: Prepare thumbmediaid

5.1 Primary: first image in note as cover

Take the first image reference (top-to-bottom), resolve file/download if needed, then upload as thumb:

thumb_media_id=$(node-wxcli material upload --type thumb --file <first-image-file> --json | jq -r '.media_id')

5.2 Fallback: latest Weixin image material

If note has no image:

image_count=$(node-wxcli material count --json | jq -r '.image_count')
offset=$((image_count - 1))
thumb_media_id=$(node-wxcli material list --type image --offset "$offset" --count 1 --json | jq -r '.item[0].media_id')

If no image materials exist, ask user to provide/upload cover and pass --thumb-media-id.

Step 6: Build digest with AI summarization

If digest is not provided, summarize the final Markdown content with AI and generate a concise Chinese digest:

• 1-2 sentences
• Prefer 60-120 Chinese characters
• Plain text only (no Markdown / emoji / line breaks)
• Focus on the article purpose and key outcomes

Step 7: Create draft from Markdown stdin

When using Markdown format, always pass --css-path. If css_path is missing, set:

css_path=${css_path:-assets/default.css}

node-wxcli draft add \
  --title "<note_title_or_custom_title>" \
  --author "<author>" \
  --digest "<digest>" \
  --format markdown \
  --content - \
  --css-path <css_path> \
  --need-open-comment=1 \
  --only-fans-can-comment=0 \
  --thumb-media-id "$thumb_media_id" < <workdir>/note.md

Resources

• references/cli-commands.md: canonical command snippets (obsidian-cli + node-wxcli).
• assets/default.css: default CSS for --format markdown (--css-path).

Notes

• Prefer notepath over notetitle.
• Only use manual --thumb-media-id when first-image and fallback both fail.
