## Components

### Content Discoverability

- **Score:** 67/100 · **Status:** fail
- **Summary:** 2 failed 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 2,482 characters (under 50,000 threshold)
- ✅ **LLMS TXT Links Resolve** — All 4 same-origin links resolve (11 total links)
- ❌ **LLMS TXT Links Markdown** — Same-origin links point to HTML and no markdown alternatives detected (7 external links excluded) Your llms.txt links point to HTML pages. Update them to .md URL variants so agents receive markdown instead of converted HTML.
- ❌ **LLMS TXT Directive** — No llms.txt directive found in any of 4 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 (0/4 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 (0/4 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:** 79/100 · **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 4 pages contain server-rendered content
- ⏭️ **Page Size Markdown** — Skipped: dependency check did not pass
- ❌ **Page Size Html** — 1 of 4 pages convert to over 100K chars (max 292K, 37% boilerplate) 1 of 4 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 4 pages (median 2%)

### 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 4 pages
- ✅ **Section Header Quality** — No tabbed content found; header quality check not applicable
- ✅ **Markdown Code Fence Validity** — All 0 code fences properly closed across 1 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 4 pages return proper error codes for bad URLs
- ✅ **Redirect Behavior** — No redirects detected across 4 pages

### 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 4939 URLs but none are under the docs path prefix (/docs)
- ⏭️ **Markdown Content Parity** — Skipped: dependency check did not pass
- ✅ **Cache Header Hygiene** — All 5 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 4 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.
