## Components

### Content Discoverability

- **Score:** 81/100 · **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 7,871 characters (under 50,000 threshold)
- ✅ **LLMS TXT Links Resolve** — All 15 same-origin sampled links resolve (51 total links)
- ⚠️ **LLMS TXT Links Markdown** — Same-origin links point to HTML, but 2 have .md variants available Some links in your llms.txt point to HTML pages instead of markdown. Where possible, update links to use .md URLs so agents get clean markdown content directly.
- ❌ **LLMS TXT Directive** — No llms.txt directive found in any of 15 sampled pages 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:** 84/100 · **Status:** partial
- **Summary:** 2 warnings 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** — 13/15 sampled pages support .md URLs (87%); 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** — Content negotiation partially supported: 12 correct type, 0 wrong type, 3 HTML only Your server returns markdown content for Accept: text/markdown requests but with an incorrect Content-Type header. Set the response Content-Type to text/markdown for proper agent handling.

### Page Size and Truncation Risk

- **Score:** 68/100 · **Status:** fail
- **Summary:** 1 failed and 1 warning 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 13 pages between 50K–100K chars (max 55K) 1 of 13 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** — 14 of 15 sampled pages convert to over 100K chars (max 3096K, 15% boilerplate) 14 of 15 pages convert to over 100K characters of markdown. Reduce inline CSS/JS, break large pages, or provide markdown versions as a smaller alternative.
- ✅ **Content Start Position** — Content starts within first 10% on all 15 sampled pages (median 2%)

### Content Structure

- **Score:** 100/100 · **Status:** partial
- **Summary:** 1 skipped across 3 AFDocs checks.
- **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** — 5 tab group(s) across 3 of 15 sampled pages; all serialize under 50K chars
- ⏭️ **Section Header Quality** — 3 page(s) with tabs found, but no section headers inside tab panels to evaluate
- ✅ **Markdown Code Fence Validity** — All 59 code fences properly closed across 14 pages

### URL Stability and Redirects

- **Score:** 98/100 · **Status:** partial
- **Summary:** 1 warning across 2 AFDocs checks.
- **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** — 2 of 15 sampled pages use cross-host redirects 2 pages use cross-host HTTP redirects, which some agents don't follow. Where possible, use same-host redirects or update URLs to point directly to the final destination.

### Observability and Content Health

- **Score:** 35/100 · **Status:** fail
- **Summary:** 1 failed and 1 warning 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 45/1979 sitemap doc pages (2%); 1934 missing; 6 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. 1934 live pages are missing from the index. Regenerate llms.txt from your sitemap or build pipeline.
- ⚠️ **Markdown Content Parity** — 2 of 13 pages have minor content differences between markdown and HTML 2 pages have minor content differences between their markdown and HTML versions. Review for formatting variations.
- ✅ **Cache Header Hygiene** — All 16 endpoints have appropriate cache headers

### Authentication and Access

- **Score:** 100/100 · **Status:** partial
- **Summary:** 1 skipped 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** — All 15 sampled pages are publicly accessible
- ⏭️ **Auth Alternative Access** — All docs pages are publicly accessible; no alternative access paths needed

### 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 falls outside the expected range.
- ✅ **LLMS Full Valid** — llms-full.txt has a recognizable markdown structure.
- ✅ **LLMS Full Links Resolve** — llms-full.txt links resolve successfully.

### Agent Skills

- **Score:** 100/100 · **Status:** pass
- **Summary:** skill.md passes all checks.
- **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** — Found an agent skill definition.

### MCP Server

- **Score:** 100/100 · **Status:** pass
- **Summary:** MCP passes all checks.
- **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** — Found an MCP server.
- ✅ **MCP Tool Count** — The MCP server exposes tools.
