Wps Doc Scraper Skill for Claude

WPS Doc Scraper

Overview

Archive WPS/KDocs public documents with source fidelity. Prefer unauthenticated data APIs, keep the raw payloads, capture the original visual artifact when the document is a canvas or mind map, and generate Markdown only as a structured representation of the source.

This is an extraction skill, not a writing skill. Do not use an LLM to rewrite, summarize, smooth, or infer missing document content unless the user explicitly asks for a separate analysis after the archive is complete.

Workflow Decision Tree

• Identify the URL type.
• kdocs.cn/view/l/<share_id> or kdocs.cn/l/<share_id>: read public link metadata first.
• wps.processon.com/diagrams/view?...: extract file_id and group_id, then use the ProcessOn data API.
• wps.processon.com/wpsapi/diagrams/view/api?...: treat as the source API directly.
• Other WPS/KDocs pages: collect public metadata, try official public export/download only when available, then use browser DOM capture as a fallback.

• For ProcessOn .pof mind maps or canvases, run the API extractor:

   python3 /path/to/wps-doc-scraper/scripts/wps_processon_extract.py \
     --url "https://www.kdocs.cn/view/l/..." \
     --output-dir "/path/to/archive-dir"

Expected outputs: processon-api.json, processon-definition.json, capture-manifest.json, and <title>.md.

• Capture the original image.
• If the page exposes a rendered SVG, save the serialized full SVG as <title>-全画布.svg.
• If the SVG uses foreignObject, do not trust ImageMagick alone for text rendering. Use scripts/render_svg_tiles.py to make the PNG through macOS Quick Look square tiles.

   python3 /path/to/wps-doc-scraper/scripts/render_svg_tiles.py \
     --svg "/path/to/<title>-全画布.svg" \
     --output "/path/to/<title>-全画布.png"

• Validate the archive.
• Markdown is a structural conversion, not an editorial rewrite.
• The original image exists for visual documents.
• Raw JSON and manifest exist.
• No output text contains the Unicode replacement character �.
• Any failed or permission-limited path is recorded in the manifest or final response.

Hard Rules

• Never log in, save to an account, copy into the user's cloud drive, or mutate the remote document unless the user explicitly requests it.
• Never bypass CAPTCHAs, paywalls, tenant restrictions, or permission walls. A public link that requires login is a hard boundary unless the user provides authorized access.
• Do not infer hidden nodes or missing text. Preserve what the API or rendered DOM actually exposes.
• HTTP 200 is not enough. Detect login-wall payloads such as 用户未登录, empty definitions, and placeholder shells.
• Keep raw source artifacts before transformation: API JSON, parsed definition JSON, serialized SVG, screenshots or PNGs, and a capture manifest.
• For browser fallback, capture DOM/source data before screenshots when possible; screenshots alone are not a faithful text archive.
• Report extraction gaps plainly. Do not silently produce a polished Markdown file from partial data.

Bundled Resources

scripts/

• wps_processon_extract.py: deterministic extractor for public WPS/KDocs ProcessOn .pof mind maps. It resolves KDocs share metadata, downloads the ProcessOn data API JSON, parses the embedded definition, and writes Markdown plus a manifest.
• render_svg_tiles.py: macOS Quick Look based SVG-to-PNG renderer for full-canvas SVGs with foreignObject text. It renders square vertical tiles and stitches them into one PNG.

references/

• processon-mindmap-api.md: endpoint pattern and payload shape for WPS-hosted ProcessOn files.
• rendered-svg-capture.md: browser-side process for extracting the rendered full-canvas SVG and producing a PNG.
• capture-manifest.md: minimum manifest fields and acceptance checks.
• permission-and-failure-boundaries.md: login walls, forbidden escalation, and failure reporting rules.
