# Agent Score Fix Report — Vast URL: https://vast.ai/docs Score: 72/100 (Grade C) I need help improving the AI-readiness of the documentation at https://vast.ai/docs. Agent Score found 6 failing checks and 1 warnings. ## Failing Checks (6) - [content-discoverability] Llms Txt Links Resolve: Only 9/10 same-origin sampled links resolve (90%); 1 broken (3 external links also failed; may be bot-detection or rate-limiting) - [content-discoverability] Llms Txt Links Markdown: Same-origin links point to HTML and no markdown alternatives detected (18 external links excluded) - [content-discoverability] Llms Txt Directive: No llms.txt directive found in any of 9 sampled pages; 1 failed to fetch - [markdown-availability] Markdown Url Support: No sampled pages support .md URLs (0/10 tested) - [markdown-availability] Content Negotiation: Server ignores Accept: text/markdown header (0/10 sampled pages return markdown) - [page-size] Content Start Position: 1 of 10 sampled pages have content starting past 50% (worst 62%) ## Warnings (1) - [content-discoverability] Llms Txt Valid: llms.txt contains parseable links but doesn't fully follow the proposed structure: https://vast.ai/llms.txt: No H1 heading found, No blockquote summary found, No heading-delimited sections found ## Fix Instructions For each issue above, please: 1. Analyze the documentation site at https://vast.ai/docs 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://vast.ai/docs --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
