Square scores 56/100 (Grade F), passing 8 of 22 checks (36%). There are 10 issues limiting AI agent readiness. Addressing llms.txt support and markdown availability would provide the most improvement.
# Agent Score Fix Report — Square URL: https://developer.squareup.com/docs Score: 56/100 (Grade F) I need help improving the AI-readiness of the documentation at https://developer.squareup.com/docs. Agent Score found 7 failing checks and 3 warnings. ## Failing Checks (7) - [content-discoverability] Llms Txt Size: llms.txt is 104,117 characters (exceeds 100,000 threshold; will be truncated by most agents) - [content-discoverability] Llms Txt Links Resolve: Only 0/10 same-origin sampled links resolve (0%); 10 broken - [content-discoverability] Llms Txt Links Markdown: Same-origin links point to HTML and no markdown alternatives detected - [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); 3 rate-limited (HTTP 429) - [page-size] Page Size Html: 2 of 10 sampled pages convert to over 100K chars (max 125K, 65% boilerplate) ## Warnings (3) - [content-discoverability] Llms Txt Valid: llms.txt contains parseable links but doesn't fully follow the proposed structure: https://developer.squareup.com/llms.txt: No H1 heading found, No blockquote summary found - [page-size] Content Start Position: 7 of 10 sampled pages have content starting at 10–50% (worst 16%) - [observability] Llms Txt Freshness: llms.txt covers 448/520 sitemap doc pages (86%); 72 missing; 24 llms.txt links not in sitemap (may indicate stale links or incomplete sitemap) ## Fix Instructions For each issue above, please: 1. Analyze the documentation site at https://developer.squareup.com/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://developer.squareup.com/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
