platform.claude.com llms.txt
In short
platform.claude.com serves a 92 KB llms.txt with 848 links. The crawl kept and parsed the first 60 KB of it, which holds 5 H2 sections, graded B on the llmstxt.org structure (5 of 6 checks). It lacks a blockquote summary. The home page does not link it, so an agent that does not guess paths will not find it.

The parse
The crawl recorded 848 links in the whole 92 KB file but kept only its first 60 KB, which is what is parsed here. In that part, 539 links appear: 539 point at claude.com or a relative path, 0 point elsewhere. The hosts it links most: platform.claude.com (539).
| H2 section | Links |
|---|---|
| Root URL | 0 |
| MCP server | 0 |
| SDK versions | 0 |
| Available Languages on Website | 0 |
| English | 539 |
Grade against the llmstxt.org structure
The file passes 5 of 6 checks and fails 1: has a blockquote summary under the h1. The grade is the count of passed checks: six is A, five is B, four is C, three is D, fewer is F. It measures structure only. Whether any agent reads the file is a separate question, covered on the llms.txt reference.
| Check | Result | Detail |
|---|---|---|
| Starts with an H1 naming the site or project | Pass | H1: Anthropic Developer Documentation |
| Has a blockquote summary under the H1 | Fail | No blockquote summary before the first H2. |
| Has at least one H2 section that lists links | Pass | 5 H2 sections, 1 with links. |
| At least 80 percent of links point at the same site | Pass | 539 of 539 links stay on claude.com (100 percent). |
| Under 100 KB | Pass | 93927 bytes as served. |
| Plain markdown, no HTML | Pass | No HTML document markers in the body. |
Ora's cached score
Ora's cached report for platform.claude.com gives it 70 of 100, grade B, scanned on 12 October 2026. Its Access layer, which holds the read-layer checks below, scored 36 of 60 check points. Read from GET ora.ai/api/score/platform.claude.com on 5 November 2026. The score is Ora's, not this site's, and the structure grade above is a different measure: it grades the llms.txt file against the llmstxt.org proposal, while Ora's score covers the whole site. Ora's report for platform.claude.com has every layer.

Linking and the companion file
The home page of platform.claude.com does not link the file in its HTML. Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens.
How it compares
At 92 KB the file is larger than 94 percent of the 2,529 plain-text llms.txt files in this edition, and its 848 links put it ahead of 96 percent of them on link count. The home page declares no generator. Size bucket: 50 to 100 KB. Curated example. Category: AI lab.
Why it is in the index: Large developer-docs index; docs.anthropic.com redirects to it. Owner as listed: Anthropic.
