Ora's cached score: 85, grade B, scanned 3 November 2026. ## The parse The crawl recorded 7,679 links in the whole 2.4 MB file but kept only its first 60 KB, which is what is parsed here. In that part, 379 links appear: 379 point at twilio.com or a relative path, 0 point elsewhere.

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](https://agentreadyhtml.com/llms-txt/). | Check | Result | Detail | | --- | --- | --- | | Starts with an H1 naming the site or project | Fail | No H1 line found. | | 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, 5 with links. | | At least 80 percent of links point at the same site | Pass | 379 of 379 links stay on twilio.com (100 percent). | | Under 100 KB | Fail | 2507650 bytes as served. | | Plain markdown, no HTML | Pass | No HTML document markers in the body. | ## Ora's cached score Ora's cached report for twilio.com gives it **85 of 100, grade B**, scanned on 3 November 2026. Its Access layer, which holds the read-layer checks below, scored 52 of 61 check points. Read from GET ora.ai/api/score/twilio.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 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. No llms-full.txt was found at the same root. ## How it compares At 2.4 MB the file is larger than 100 percent of the 2,529 plain-text llms.txt files in this edition, and its 7,679 links put it ahead of 100 percent of them on link count. The home page declares no generator. Size bucket: 100 KB and over. Tranco rank 1,118. Category: Communication & Support. Why it is in the index: About 2.5 MB and nearly 10,000 links, linked from the home page; far past any context window. Owner as listed: Twilio.
