## Components

### Content Discoverability

- **Score:** 45/100 · **Status:** fail
- **Summary:** 2 failed, 1 warning, and 2 skipped 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 contains parseable links but doesn't fully follow the proposed structure: https://vercel.com/llms.txt: No H1 heading found; https://vercel.com/docs/llms.txt: No H1 heading found Your llms.txt contains parseable links but doesn't follow the standard structure. Add an H1 title as the first line and a blockquote summary (lines starting with >) to improve agent parsing.
- ❌ **LLMS TXT Size** — llms.txt is 167,660 characters (exceeds 100,000 threshold; will be truncated by most agents) Your llms.txt is 167,660 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** — llms.txt contains 1428 links, but none are under /dics
- ⏭️ **LLMS TXT Links Markdown** — llms.txt contains 1428 links, but none are under /dics
- ❌ **LLMS TXT Directive** — No llms.txt directive found in any of 1 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:** 0/100 · **Status:** fail
- **Summary:** 2 failed 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** — No pages support .md URLs (0/1 tested) Your pages don't return markdown when .md is appended to the URL. Configure your docs platform to serve .md variants for all documentation pages.
- ❌ **Content Negotiation** — Server ignores Accept: text/markdown header (0/1 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:** 67/100 · **Status:** fail
- **Summary:** 1 failed and 1 skipped 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 1 pages contain server-rendered content
- ⏭️ **Page Size Markdown** — Skipped: dependency check did not pass
- ❌ **Page Size Html** — 1 of 1 pages convert to over 100K chars (max 170K, 8% boilerplate) 1 of 1 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 1 pages (median 8%)

### 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 1 pages
- ✅ **Section Header Quality** — No tabbed content found; header quality check not applicable
- ✅ **Markdown Code Fence Validity** — All 0 code fences properly closed across 2 pages

### URL Stability and Redirects

- **Score:** 36/100 · **Status:** fail
- **Summary:** 1 failed 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** — 1 of 1 pages return 200 for non-existent URLs (soft 404) Your site returns 200 for non-existent pages (soft 404). Agents try to extract information from the error page content instead of recognizing the page is missing. Configure your server to return 404 for pages that don't exist.
- ✅ **Redirect Behavior** — All 1 redirect(s) across 1 pages are same-host HTTP redirects

### Observability and Content Health

- **Score:** 100/100 · **Status:** partial
- **Summary:** 2 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 7016 URLs but none are under the docs path prefix (/dics)
- ⏭️ **Markdown Content Parity** — Skipped: dependency check did not pass
- ✅ **Cache Header Hygiene** — All 3 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 1 pages are publicly accessible
- ⏭️ **Auth Alternative Access** — All docs pages are publicly accessible; no alternative access paths needed

### Full Content Discoverability

- **Score:** 50/100 · **Status:** fail
- **Summary:** llms-full.txt has 2 failing checks.
- **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 is missing the expected markdown structure.
- ✅ **LLMS Full Links Resolve** — llms-full.txt links 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.
