archibate Read URL
Work down this fallback ladder in order. Each step is only tried when prior steps don't apply or fail.
Fallback ladder
- Raw
.md/.txt/ plain-text URL →curl -sL <url>(already clean, no HTML to strip) - Known site → use the dedicated CLI/API from the routing table below
- Docs page → try
curl -sL <url>.md. Mintlify and other docs platforms serve clean markdown on the.mdroute — if the response istext/markdown, you're done; otherwise fall through - Blog / newsletter / multi-post index → try RSS first:
curl -sL <url>/feed(also/rss,/feed.xml,/atom.xml,/index.xml). Most static-site generators and CMS platforms expose one; RSS gives you clean<content:encoded>or<summary>bodies without chrome - Generic site (articles, docs, tech blogs, unknown) →
npx defuddle parse <url> --markdown— seereferences/defuddle.md - JS-rendered page (defuddle returns empty / skeleton-only content) →
/agent-browserskill - Cloudflare / anti-bot protection (Turnstile, blocked responses, 403/503) →
/scraplingskill - Still blocked and genuinely need this page → ask the user to open it and paste the content, or offer the
/chrome-cdpskill (requires explicit user approval first). Otherwise, give up and report the failure.
Routing table
Step 2 — URLs matching a known domain:
| Domain / Pattern | Preferred path |
|---|---|
github.com / gist.github.com |
File via raw.githubusercontent.com; issue/PR via gh issue view / gh pr view; search via anonymous api.github.com/search/issues — see references/github.md |
x.com / twitter.com / t.co |
curl -sL https://api.fxtwitter.com/<user>/status/<id> | jq |
bilibili.com |
/bilibili-api skill — fetches video title, description, comments |
youtube.com / youtu.be |
yt-dlp --dump-json --skip-download for title/description/metadata; yt-dlp --write-auto-sub --sub-lang en --skip-download for transcript |
arxiv.org / ssrn.com |
/jina-ai skill |
mp.weixin.qq.com (微信公众号) |
/scrapling skill — scrapling extract get <url> works without a browser |
www.cnblogs.com (博客园) |
Plain defuddle works — server-rendered HTML with the article body inline. For a user's post index: curl -sL 'https://www.cnblogs.com/<user>/rss' (Atom feed) |
blog.csdn.net (CSDN) |
/scrapling skill — plain curl returns a JS-skeleton (content is JS-loaded) and defuddle hits 404 anti-bot. For a summary-only index: curl -sL 'https://blog.csdn.net/<user>/rss/list' returns RSS with 摘要 (not full bodies) |
zhihu.com / zhuanlan.zhihu.com (知乎) |
Hard — plain curl returns a bot-challenge page and even scrapling's stealthy-fetch gets 403 with empty content. Try /chrome-cdp with the user's logged-in session, or ask them to paste the content |
juejin.cn (掘金) |
/scrapling skill — Nuxt SPA; escalate to /chrome-cdp if stealthy-fetch returns only shell |
segmentfault.com (思否) |
/scrapling skill — custom HTTP 468 anti-bot; escalate to /chrome-cdp if stealthy-fetch fails |
weibo.com (微博) |
/scrapling skill — JS-rendered status pages; escalate to /chrome-cdp if stealthy-fetch returns only chrome |
xiaohongshu.com (小红书) |
/scrapling skill — aggressive anti-bot; escalate to /chrome-cdp if stealthy-fetch fails |
y.qq.com (QQ 音乐) |
Hard — stealthy-fetch returns the homepage shell instead of song data. Use /chrome-cdp with the user's logged-in session, or ask them to paste |
music.163.com (网易云音乐) |
Plain defuddle for basic info — <title> has song + artist. For lyrics / comments / playlists use the community-maintained NeteaseCloudMusicApi (self-hosted Node proxy over the internal API) |
wallstreetcn.com (华尔街见闻) |
Plain defuddle works — server-rendered with _articleBody_… class; no auth needed for public articles |
www.v2ex.com (V2EX) |
curl -sL 'https://www.v2ex.com/api/topics/show.json?id=<id>' | jq — returns topic + full content; api/replies/show.json?topic_id=<id> for replies |
gitee.com |
Known file path: curl -sL 'https://gitee.com/<owner>/<repo>/raw/<ref>/<path>'. Repo metadata: curl -sL 'https://gitee.com/api/v5/repos/<owner>/<repo>' | jq. Shape mirrors GitHub |
instagram.com |
instaloader CLI |
reddit.com |
Hard — .json endpoints are blocked since the 2023 API changes, and scrapling's stealthy-fetch gets a captcha page. Use the official OAuth API (PRAW / snoowrap) with credentials, or /chrome-cdp with the user's logged-in session |
stackoverflow.com / *.stackexchange.com / superuser.com / serverfault.com / askubuntu.com |
Stack Exchange API — see references/stackexchange.md |
*.fandom.com |
/scrapling skill — Fandom sits behind Cloudflare, plain curl returns the "Just a moment..." challenge regardless of path or User-Agent |
Any other MediaWiki site — Wikipedia, Arch Wiki, cppreference, *.wiki.gg, etc. |
Wikimedia-run wikis use the REST API + prop=extracts; third-party wikis use ?action=raw or api.php?action=parse (some need defuddle due to heavy templates) — see references/mediawiki.md |
www.rfc-editor.org / any RFC |
curl -sL 'https://www.rfc-editor.org/rfc/rfc<N>.txt' — canonical plaintext, no chrome. .html and .json also available (the JSON has metadata like obsoleted-by, authors, status) |
peps.python.org |
Individual PEP: curl -sL 'https://peps.python.org/pep-<N>/' (clean HTML). All PEPs indexed: curl -sL 'https://peps.python.org/api/peps.json' | jq — number, title, status, authors, created date |
docs.claude.com / docs.anthropic.com (Anthropic & Claude Code docs) |
Append .md to the URL. Indexes: platform.claude.com/llms.txt (+ llms-full.txt) for API/SDK pages; code.claude.com/llms.txt for Claude Code |
news.ycombinator.com |
curl -sL 'https://hn.algolia.com/api/v1/items/<id>' | jq — returns story + full comment tree as nested JSON |
pypi.org |
curl -sL 'https://pypi.org/pypi/<package>/json' | jq -r '.info.description' for README; .info.summary / .info.version for metadata |
npmjs.com / registry.npmjs.org |
npm view <package> readme for README; curl -sL 'https://registry.npmjs.org/<package>' | jq for full metadata |
lobste.rs |
append .json to the story URL (e.g. lobste.rs/s/<id>.json), fetch with curl |
dev.to |
curl -sL 'https://dev.to/api/articles/<id>' | jq -r '.title, .body_markdown' — <id> is the numeric article ID |
*.substack.com |
<subdomain>.substack.com/feed — RSS with full post HTML in <content:encoded> |
medium.com / *.medium.com |
curl -sL 'https://medium.com/feed/@<user>' — RSS returns the last ~10 posts with full content:encoded HTML. Direct article URLs return a ~4KB paywall shell and need /scrapling if the piece isn't in the user's recent feed |
bsky.app |
curl -sL 'https://public.api.bsky.app/xrpc/app.bsky.feed.getPostThread?uri=<at-uri>' | jq — no auth needed for public posts; convert bsky.app/profile/<handle>/post/<rkey> to at://<handle>/app.bsky.feed.post/<rkey> |
gitlab.com |
Known file path (preferred): curl -sL https://gitlab.com/<owner>/<repo>/-/raw/<ref>/<path>. Repo metadata / MR / issue bodies: curl -sL 'https://gitlab.com/api/v4/projects/<owner>%2F<repo>' | jq (URL-encode the slash in the project path) |
codeberg.org / any Gitea or Forgejo instance |

aur.archlinux.org |
curl -sL 'https://aur.archlinux.org/rpc/v5/info/<pkg>' | jq -r '.results[0]' — Name, Version, Description, Maintainer, Depends, URL |
doi.org / any bare DOI |
curl -sL 'https://api.crossref.org/works/<doi>' | jq -r '.message | .title[0], (.author[].family | tostring)' — reliable for title + authors + citation metadata (abstract hit-or-miss). Prefer /jina-ai or the publisher page for full text |
Any Discourse forum (discuss.python.org, meta.discourse.org, forum.rust-lang.org, discuss.pytorch.org, etc.) |
Append .json to the topic URL: curl -sL '<forum>/t/<slug>/<id>.json' | jq — returns topic + all posts in post_stream.posts |
huggingface.co |
README via <repo>/raw/main/README.md; metadata via /api/models, /api/datasets, /api/papers — see references/huggingface.md |
web.archive.org / any Wayback lookup |
Find closest snapshot: curl -sL 'https://archive.org/wayback/available?url=<url>×tamp=<YYYYMMDD>' | jq. Fetch raw archived response: curl -sL 'https://web.archive.org/web/<timestamp>id_/<url>' — the id_ suffix strips Wayback's toolbar injection and returns the original response body |
store.steampowered.com |
curl -sL 'https://store.steampowered.com/api/appdetails?appids=<appid>&cc=us&l=en' | jq -r '.["<appid>"].data' — name, short_description, release_date, developers, categories, price |

curl -sL '<site>/wp-json/wp/v2/posts?per_page=10' | jq for recent posts; /wp-json/wp/v2/posts/<id> for a single post (.content.rendered has the HTML body). Works on any WP install with the REST API enabled — still the default |
openlibrary.org |
curl -sL 'https://openlibrary.org/works/OL<id>W.json' | jq for works; /isbn/<isbn>.json for ISBN lookup; /authors/OL<id>A.json for authors. Note: .description is sometimes a string, sometimes {type, value} — handle both |
gutenberg.org (Project Gutenberg) |
curl -sL 'https://www.gutenberg.org/cache/epub/<id>/pg<id>.txt' — full plaintext of out-of-copyright books |
Bulk discovery
For whole-site ingestion, probe <site>/llms.txt (URL index) and /llms-full.txt (full corpus). Convention adopted by Mintlify, Cloudflare, Stripe, Next.js, and others.
vs. WebFetch
This skill returns full page text (markdown), parsed locally — no summarization, no information loss. WebFetch routes through a remote small model that may summarize, refuse, or truncate; reach for it only when you want an AI summary, not the content itself.
When to bypass the ladder
- Need a quick AI summary → built-in WebFetch
- No specific URL yet, need to search → built-in WebSearch or
