## Components

### Content Discoverability

- **Score:** 73/100 · **Status:** fail
- **Summary:** 1 failed and 1 warning across 6 AFDocs checks.
- **Rationale:** Agents need a clear entry point and crawl map before they can reliably discover the right pages.
- **Reference:** [AFDocs reference](https://afdocs.dev)

**Checks**

- ✅ **LLMS TXT Exists** — llms.txt found at 1 location(s)
- ✅ **LLMS TXT Valid** — llms.txt follows the proposed structure (H1, blockquote, heading-delimited link sections)
- ⚠️ **LLMS TXT Size** — llms.txt is 81,407 characters (between 50,000 and 100,000; consider splitting) Your llms.txt is 81,407 characters, which may be truncated on some agent platforms. If it grows further, split into nested llms.txt files with a root index under 50,000 characters.
- ✅ **LLMS TXT Links Resolve** — All 15 same-origin sampled links resolve (235 total links)
- ✅ **LLMS TXT Links Markdown** — 15/15 same-origin sampled links point to markdown content (100%)
- ❌ **LLMS TXT Directive** — No llms.txt directive found in any of 4 sampled pages; 11 failed to fetch No agent-facing directive pointing to llms.txt was detected on any tested page. Add a blockquote near the top of each page (e.g., "> For the complete documentation index, see [llms.txt](/llms.txt)"). This can be visually hidden with CSS while remaining accessible to agents.

### Markdown Availability

- **Score:** 47/100 · **Status:** fail
- **Summary:** 1 failed and 1 warning across 2 AFDocs checks.
- **Rationale:** When markdown is available directly, agents spend less effort stripping presentation markup and guessing structure.
- **Reference:** [AFDocs reference](https://afdocs.dev)

**Checks**

- ⚠️ **Markdown Url Support** — 11/15 sampled pages support .md URLs (73%); inconsistent support 0 of 15 pages support .md URLs inconsistently. Ensure all documentation pages serve markdown when .md is appended to the URL.
- ❌ **Content Negotiation** — Server ignores Accept: text/markdown header (0/15 sampled pages return markdown) Your server ignores Accept: text/markdown and returns HTML. Some agents (Claude Code, Cursor, OpenCode) request markdown this way. Configure your server to honor content negotiation.

### Page Size and Truncation Risk

- **Score:** 83/100 · **Status:** fail
- **Summary:** 1 failed and 2 warnings across 4 AFDocs checks.
- **Rationale:** Large pages and delayed primary content increase truncation risk and make retrieval less reliable.
- **Reference:** [AFDocs reference](https://afdocs.dev)

**Checks**

- ✅ **Rendering Strategy** — All 15 sampled pages contain server-rendered content
- ⚠️ **Page Size Markdown** — 1 of 11 pages between 50K–100K chars (max 52K) 1 of 11 markdown pages are between 50K and 100K characters. These may be truncated on some agent platforms or routed through summarization. Consider splitting large pages.
- ⚠️ **Page Size Html** — 1 of 15 sampled pages convert to 50K–100K chars (max 54K, 65% boilerplate) 1 of 15 pages convert to 50K-100K characters of markdown. These may be truncated on some agent platforms.
- ❌ **Content Start Position** — 13 of 15 sampled pages have content starting past 50% (worst 102%) 13 of 15 pages have content starting past 50% of the converted output. Agents may never see the documentation content. Move or remove inline CSS/JS that precedes the content area.

### Content Structure

- **Score:** 100/100 · **Status:** pass
- **Summary:** 3 AFDocs checks pass.
- **Rationale:** Predictable sections, valid code fences, and serialized tabs make the content easier for agents to parse correctly.
- **Reference:** [AFDocs reference](https://afdocs.dev)

**Checks**

- ✅ **Tabbed Content Serialization** — No tabbed content detected across 15 sampled pages
- ✅ **Section Header Quality** — No tabbed content found; header quality check not applicable
- ✅ **Markdown Code Fence Validity** — All 17 code fences properly closed across 12 pages

### URL Stability and Redirects

- **Score:** 100/100 · **Status:** pass
- **Summary:** 2 AFDocs checks pass.
- **Rationale:** Stable URLs and sane redirect behavior prevent retrieval drift and broken tool references.
- **Reference:** [AFDocs reference](https://afdocs.dev)

**Checks**

- ✅ **Http Status Codes** — All 15 sampled pages return proper error codes for bad URLs
- ✅ **Redirect Behavior** — All 2 redirect(s) across 15 sampled pages are same-host HTTP redirects

### Observability and Content Health

- **Score:** 29/100 · **Status:** fail
- **Summary:** 3 failed across 3 AFDocs checks.
- **Rationale:** Coverage, parity, and cache behavior determine whether agents can trust the content they retrieve.
- **Reference:** [AFDocs reference](https://afdocs.dev)

**Checks**

- ❌ **LLMS TXT Freshness** — llms.txt covers 94/483 sitemap doc pages (19%); 389 missing; 261 llms.txt links not in sitemap (may indicate stale links or incomplete sitemap) Your llms.txt covers less than 80% of your site's pages. 389 live pages are missing from the index. Regenerate llms.txt from your sitemap or build pipeline.
- ❌ **Markdown Content Parity** — Could not fetch HTML for any pages to compare; 11 failed to fetch 0 pages have substantive content differences between markdown and HTML (avg 0% missing). Agents receiving the markdown version are getting outdated or incomplete content. Regenerate markdown from source or fix the build pipeline.
- ❌ **Cache Header Hygiene** — 4 of 16 endpoints have aggressive caching or missing cache headers 4 endpoints have aggressive caching (>24h) or missing cache headers. Set max-age under 3600 or add must-revalidate with ETag/Last-Modified so content updates reach agents promptly.

### Authentication and Access

- **Score:** 81/100 · **Status:** partial
- **Summary:** 1 warning across 2 AFDocs checks.
- **Rationale:** Agents need either public access or a clear alternative path when documentation is gated behind auth.
- **Reference:** [AFDocs reference](https://afdocs.dev)

**Checks**

- ⚠️ **Auth Gate Detection** — 4 of 15 sampled pages require authentication (11 accessible) Some documentation pages require authentication while others are public. Agents can access public pages but will fall back on training data for gated content. Consider ungating reference docs and API guides.
- ✅ **Auth Alternative Access** — Alternative access detected (public-llms-txt, public-markdown, partial-public-access) for site with 4 auth-gated pages

### Full Content Discoverability

- **Score:** 75/100 · **Status:** fail
- **Summary:** llms-full.txt has 1 failing check.
- **Rationale:** A full-document snapshot gives long-context agents a single canonical corpus to ingest without repeated crawling.
- **Reference:** [llms-full.txt guide](https://www.mintlify.com/docs/ai/llmstxt#llms-full-txt)

**Checks**

- ✅ **LLMS Full Exists** — Found llms-full.txt.
- ✅ **LLMS Full Size** — llms-full.txt size is within the expected range.
- ✅ **LLMS Full Valid** — llms-full.txt has a recognizable markdown structure.
- ❌ **LLMS Full Links Resolve** — Some llms-full.txt links do not resolve successfully.

### Agent Skills

- **Score:** 0/100 · **Status:** fail
- **Summary:** skill.md has 1 failing check.
- **Rationale:** Agent skills provide product-specific operating guidance that plain documentation pages do not encode on their own.
- **Reference:** [skill.md guide](https://www.mintlify.com/docs/ai/skillmd)

**Checks**

- ❌ **Skill MD** — No agent skill definition was discovered.

### MCP Server

- **Score:** 0/100 · **Status:** fail
- **Summary:** MCP has 1 failing check.
- **Rationale:** A discoverable MCP server lets agents use first-class tools instead of scraping pages and inferring behavior.
- **Reference:** [MCP guide](https://www.mintlify.com/docs/ai/model-context-protocol)

**Checks**

- ❌ **MCP Server Discoverable** — No MCP server was discovered at the expected endpoints.
- ⏭️ **MCP Tool Count** — Skipped because the MCP server was not discoverable.
