> Auto-updating archive of Anthropic's builder documentation: every source
> that publishes markdown, fetched 4x daily. 4,100 files from six live sources,
> plus a frozen archive of the engineering blog.
Clone this repo and point Claude Code at it. Every doc, tutorial, cookbook,
skill, and engineering post Anthropic publishes on a markdown surface --
searchable, version-controlled, and offline.
Install
Then ask Claude Code anything:
Content
Counts are files on disk as of 2026-09-09; uv run scripts/fetcher.py --tree
prints them live.
| Source | Section | Files | What |
|--------|---------|------:|------|
| code.claude.com | --section claude-code | 198 | Claude Code + Agent SDK docs |
| platform.claude.com | --section api | 2,228 | API reference, build guides |
| claude.com/docs | --section products | 226 | Claude Tag, Cowork, office agents, connectors |
| modelcontextprotocol.io | --section mcp | 347 | MCP spec, SDKs, governance |
| github.com/anthropics | --section github | 764 | Cookbooks, skills, plugins, courses, SDK docs |
| support.claude.com | --section support | 372 | Help articles |
| anthropic.com | frozen 2026-07-08 | 158 | Engineering, research, news posts -- see below |
anthropic.com has no --section flag: it is HTML-only, the jina.ai proxy the
fetcher used was removed in July 2026, and content/blog/ has been a static
archive since 2026-07-08. What is in it, against what anthropic.com's sitemap
lists today:
| content/blog/ | Archived | Upstream | Coverage |
|---|---:|---:|---:|
| engineering/ | 25 | 25 | complete |
| product/ | 4 | 4 | complete |
| research/ | 72 | 155 | 46% |
| news/ | 57 | 260 | 22% |
The engineering posts -- "Building Effective Agents", context engineering, tool
use -- are all here. Research and news are not, and will not grow until
something converts HTML to markdown.
Fetching
Auto-updates four times daily via GitHub Actions. To fetch manually:
GitHub repo fetching needs GITHUB_TOKEN or GH_TOKEN in the environment.
Every fetched source serves a .md variant of each page, so nothing is
converted from HTML. That is also why content/blog/ is frozen: anthropic.com
is HTML-only and the jina.ai proxy path it used was removed in July 2026.
See sources.json for the complete machine-readable source
registry.
Source Discovery
The fetcher doesn't just download from hardcoded URLs. It probes every known
Anthropic domain for robots.txt, sitemap.xml, llms.txt, and — the
question that decides everything — whether the domain serves .md variants at
all. It also enumerates github.com/anthropics and watches the Location
header on every redirect it follows.
Known domains: anthropic.com, platform.claude.com, code.claude.com,
support.claude.com, modelcontextprotocol.io, claude.ai, claude.com,
academy.claude.com
**The result is a file, not a log line.** Every full run rewrites
discovery.json with what exists upstream that
sources.json does not. This matters because printing it did not work: the
pipeline had been logging support.claude.com -> academy.claude.com four
times a day for weeks, into an Actions log nobody opens, and those 725 pages
were eventually found by a human chasing a dead support article. A discovery
that isn't a diff doesn't reach anyone.
So a new domain, a new anthropics repo, or a domain that starts serving
