How that compares with the other 112 files we track, and what it implies. Last updated: August 3, 2026 ## The file **DuckDB** publishes an llms.txt at [`https://duckdb.org/llms.txt`](https://duckdb.org/llms.txt). The file declares itself as **DuckDB** in its H1, and the host is categorised here as developer tools. It was last fetched and parsed on 2026-08-03. ## Measured structure Measure DuckDB Corpus median Percentile Size 3.3 KB 14.0 KB 12th H2 sections 4 7 35th Links 12 76 18th Blockquote summary Present 90 of 113 have one n/a Percentiles are against the 113 files in this directory, not against the web. That population is deliberately weighted toward documentation platforms and developer tools, which is where the convention started, so treat it as a peer group rather than a norm. ## Observations - 12 links is a tightly curated file, well under the corpus median of 76. That is the shape the proposal describes. ℹ What this page does not tell you These are structural measurements of a text file. They say nothing about whether the pages it links to are good, whether anything actually reads it, or whether publishing it helped this site. On that last question the measured answer is sobering, and we cover it in no AI agent goes looking for your llms.txt . ## Comparable files Closest in size within developer tools, from the same weekly check: - [Postman](/llms-txt-directory/postman-com/): 3.3 KB, 5 sections, 18 links - [Vite](/llms-txt-directory/vitejs-dev/): 3.4 KB, 1 sections, 43 links - [Netlify](/llms-txt-directory/netlify-com/): 2.8 KB, 5 sections, 27 links - [Postman Learning](/llms-txt-directory/learning-postman-com/): 4.2 KB, 4 sections, 13 links , no blockquote summary ## How this was measured Our checker fetches `/llms.txt` for every host in the directory, follows redirects, confirms the response is Markdown rather than an HTML error page, and parses it with the same parser that powers our [validator](/validator/). Sizes are of the served body, sections are H2 headings, and links are Markdown links anywhere in the file. The run behind this page completed on 2026-08-03.
