## Components

### Content Discoverability

- **Score:** 56/100 · **Status:** fail
- **Summary:** 2 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 2 location(s)
- ✅ **LLMS TXT Valid** — llms.txt follows the proposed structure (H1, blockquote, heading-delimited link sections)
- ❌ **LLMS TXT Size** — llms.txt is 4,561,591 characters (exceeds 100,000 threshold; will be truncated by most agents) Your llms.txt is 4,561,591 characters and will be truncated by all major agent platforms. Split into a root index linking to section-level llms.txt files, each under 50,000 characters.
- ✅ **LLMS TXT Links Resolve** — All 15 same-origin sampled links resolve (21329 total links)
- ⚠️ **LLMS TXT Links Markdown** — Same-origin links point to HTML, but 14 have .md variants available (1 external link excluded) 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:** 55/100 · **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** — 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** — 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:** 58/100 · **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 13 pages between 50K–100K chars (max 63K) 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 555K, 32% 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** — 15 of 15 sampled pages have content starting at 10–50% (worst 44%) 15 of 15 pages have documentation content starting 10-50% into the converted output. Inline CSS or boilerplate consumes part of the agent's truncation budget before content begins.

### Content Structure

- **Score:** 74/100 · **Status:** fail
- **Summary:** 3 failed 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** — 7 tab group(s) found; worst page serializes to 221K chars (over 100K) Tabbed content on 1 pages serializes to over 100K characters. Agents see only the first few tab variants; content in later tabs is truncated. Break variants into separate pages.
- ❌ **Section Header Quality** — 2 of 2 page(s) with tab headers don't distinguish between variants Over 50% of headers are generic across tab variants. When serialized, agents cannot tell which section belongs to which variant.
- ❌ **Markdown Code Fence Validity** — 1 unclosed code fences found across 15 pages 1 pages have unclosed code fences. Everything after an unclosed fence is interpreted as code, causing agents to misread documentation as literal content. Ensure every opening ``` or ~~~ has a matching closing delimiter.

### 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 1 redirect(s) across 15 sampled pages are same-host HTTP redirects

### Observability and Content Health

- **Score:** 100/100 · **Status:** partial
- **Summary:** 1 warning and 1 skipped 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** — Sitemap has 4875 URLs but none are under the docs path prefix (/docs)
- ⚠️ **Markdown Content Parity** — 8 of 13 pages have minor content differences between markdown and HTML 8 pages have minor content differences between their markdown and HTML versions. Review for formatting variations.
- ✅ **Cache Header Hygiene** — All 17 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:** 0/100 · **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** — No llms-full.txt file was discovered.
- ⏭️ **LLMS Full Size** — Skipped because llms-full.txt was not found.
- ⏭️ **LLMS Full Valid** — Skipped because llms-full.txt was not found.
- ⏭️ **LLMS Full Links Resolve** — Skipped because llms-full.txt was not found.

### 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.
