name	md-to-xhs-cards
description	Convert a Markdown file into Xiaohongshu (Little Red Book) image cards with deterministic layout, preserving markdown structure order and embedded local images. Use when users ask for direct MD-to-XHS card conversion, markdown poster cards, 图文卡片拆分, or preserving original markdown text/format in social image outputs.

Markdown To Xiaohongshu Cards

Overview

Convert markdown content into a multi-image card set suitable for Xiaohongshu posting. Keep source ordering and formatting cues (headings, paragraphs, lists, quotes, code, dividers, images) without rewriting the content.

Quick Start

1. Resolve the markdown file path from the user request.
2. Run:

scripts/run_md_to_xhs_cards.sh /absolute/or/relative/path/to/file.md

3. Return output folder and generated card paths.

Default output folder: <markdown-dir>/<markdown-stem>-xhs-cards

Workflow

1. Validate input:

• Confirm markdown file exists.
• Confirm referenced images are local files when possible (![...](...) or Obsidian ![[...]]).

2. Execute deterministic rendering:

• Run scripts/run_md_to_xhs_cards.sh.
• Use --width and --height to match required aspect ratio.
• Use --background, --text-color, and related flags for style adjustment.
• Use --author (and optionally --title / --subtitle) for a dedicated cover card.

3. Verify output:

• Ensure at least one NN-card.png exists.
• Check manifest.json for count and filenames.
• If images are missing, report placeholders and list unresolved image paths.

4. Optional publish to Xiaohongshu:

• Add --publish-xhs to publish immediately after rendering.
• Use --publish-title / --publish-desc overrides when needed.
• For safe validation, run once with --publish-dry-run.

5. Report clearly:

• Provide absolute output directory.
• Provide absolute paths for all generated cards.
• Call out any missing/remote image limitations.

Quality Rules

• Keep direct conversion behavior: do not rewrite the article content unless user asks.
• Keep markdown block order stable.
• Preserve image placement where possible (markdown and Obsidian image embeds).
• Prefer 3:4 cards for Xiaohongshu (1080x1440 or 1242x1660).

Common Commands

Default:

scripts/run_md_to_xhs_cards.sh content/post.md

Set explicit output directory:

scripts/run_md_to_xhs_cards.sh content/post.md --output-dir exports/xhs-cards

Use larger Xiaohongshu canvas:

scripts/run_md_to_xhs_cards.sh content/post.md --width 1242 --height 1660

Style tuning:

scripts/run_md_to_xhs_cards.sh content/post.md \
  --background "#f3f3f3" \
  --text-color "#141414" \
  --muted-color "#6f6f6f" \
  --line-height-scale 1.80

Render + publish in one command:

scripts/run_md_to_xhs_cards.sh content/post.md \
  --publish-xhs \
  --publish-title "医生的病历写给谁看" \
  --publish-desc "关于病历、医疗决策，与医生的身份危机"

Dry-run publish validation:

scripts/run_md_to_xhs_cards.sh content/post.md \
  --publish-xhs \
  --publish-dry-run

User Option Packs

Soft reading style:

scripts/run_md_to_xhs_cards.sh content/post.md \
  --background "#faf9f6" \
  --quote-bg "#f4f2eb" \
  --quote-border "#e8e3d7" \
  --quote-accent "#7a756a"

Cover + ending signature:

scripts/run_md_to_xhs_cards.sh content/post.md \
  --author "鹿不角" \
  --signature-text "-- 鹿不角"

Keep author on cover too:

scripts/run_md_to_xhs_cards.sh content/post.md \
  --author "鹿医生" \
  --cover-author

Cover with author:

scripts/run_md_to_xhs_cards.sh content/post.md --author "鹿医生"

Last-page signature (without cover author):

scripts/run_md_to_xhs_cards.sh content/post.md \
  --author "鹿不角" \
  --signature-text "-- 鹿不角"

Dependencies

• scripts/run_md_to_xhs_cards.sh auto-selects a Python interpreter with Pillow.
• If none found, install:

python3 -m pip install pillow

• Optional publishing uses scripts/publish_xhs.py:
  • Local mode: python3 -m pip install xhs
  • API mode (--publish-api-mode): python3 -m pip install requests
• Cookie lookup supports:
  • --publish-cookie
  • XHS_COOKIE environment variable
  • .env in current directory / skill directory
