# Agent Score Fix Report — Datadog URL: https://docs.datadoghq.com Score: 89/100 (Grade B) I need help improving the AI-readiness of the documentation at https://docs.datadoghq.com. Agent Score found 3 failing checks and 1 warnings. ## Failing Checks (3) - [content-discoverability] Llms Txt Size: llms.txt is 1,889,208 characters (exceeds 100,000 threshold; will be truncated by most agents) - [observability] Llms Txt Freshness: llms.txt covers 7530/18181 sitemap doc pages (41%); 10651 missing; 11 llms.txt links not in sitemap (may indicate stale links or incomplete sitemap) - [observability] Markdown Content Parity: 9 of 10 pages have substantive content differences between markdown and HTML (avg 36% missing) ## Warnings (1) - [content-discoverability] Llms Txt Valid: llms.txt contains parseable links but doesn't fully follow the proposed structure: https://docs.datadoghq.com/llms.txt: No blockquote summary found ## Fix Instructions For each issue above, please: 1. Analyze the documentation site at https://docs.datadoghq.com 2. Implement the specific fix 3. Verify the fix would cause the check to pass ### Common fixes: - **No llms.txt**: Create /llms.txt following https://llmstxt.org — list all doc pages in markdown format - **No .md URL support**: Configure your docs platform to serve pages at equivalent .md URLs (e.g. /docs/quickstart.md) - **No content negotiation**: Return markdown when request includes Accept: text/markdown header - **Large page size**: Reduce nav boilerplate, inline scripts, and repetitive markup - **No sitemap**: Generate /sitemap.xml listing all documentation URLs - **Auth walls**: Ensure docs pages return 200 without requiring login cookies or tokens - **No Last-Modified header**: Configure your server/CDN to include Last-Modified response headers - **Tab content hidden**: Ensure tabbed content is rendered in the HTML (not JS-only) so agents can read all variants ## Run afdocs Locally for More Detail To get deeper visibility into what's failing, run afdocs against your docs: npx afdocs https://docs.datadoghq.com --fixes --verbose - **--fixes**: Adds "Fix:" lines to the output for each warn/fail check with actionable remediation steps - **-v, --verbose**: Shows per-page details (specific URLs, character counts, error codes) for checks with issues — useful for per-URL visibility into what's failing
