## Components

### Content Discoverability

- **Score:** 89/100 · **Status:** partial
- **Summary:** 3 warnings 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://docs.stripe.com/llms.txt: No blockquote summary found; https://docs.stripe.com/docs/llms.txt: No blockquote summary 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 93,188 characters (between 50,000 and 100,000; consider splitting) Your llms.txt is 93,188 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 (491 total links)
- ✅ **LLMS TXT Links Markdown** — 15/15 same-origin sampled links point to markdown content (100%) (8 external links excluded)
- ⚠️ **LLMS TXT Directive** — llms.txt directive found in 15 of 15 sampled pages, but buried deep in the page (past 50%) An llms.txt directive was found on some pages but is missing from others, or is buried deep in the page. Ensure the directive appears near the top of every documentation page.

### Markdown Availability

- **Score:** 91/100 · **Status:** partial
- **Summary:** 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** — 15/15 sampled pages support .md URLs (100%)
- ⚠️ **Content Negotiation** — Content negotiation partially supported: 0 correct type, 15 wrong type, 0 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:** 62/100 · **Status:** fail
- **Summary:** 2 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 15 pages between 50K–100K chars (max 71K) 1 of 15 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** — 15 of 15 sampled pages convert to over 100K chars (max 1044K, 22% boilerplate) 15 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** — 1 of 15 sampled pages have content starting past 50% (worst 53%) 1 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** — 1 tab group(s) across 1 of 15 sampled pages; all serialize under 50K chars
- ✅ **Section Header Quality** — 1 page(s) with tab headers checked; headers include variant context
- ✅ **Markdown Code Fence Validity** — All 51 code fences properly closed across 17 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** — No redirects detected across 15 sampled pages

### Observability and Content Health

- **Score:** 30/100 · **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 467/3191 sitemap doc pages (15%); 2724 missing; 11 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. 2724 live pages are missing from the index. Regenerate llms.txt from your sitemap or build pipeline.
- ❌ **Markdown Content Parity** — 1 of 15 pages have substantive content differences between markdown and HTML (avg 6% missing) 1 pages have substantive content differences between markdown and HTML (avg 6% missing). Agents receiving the markdown version are getting outdated or incomplete content. Regenerate markdown from source or fix the build pipeline.
- ❌ **Cache Header Hygiene** — 17 of 17 endpoints have aggressive caching or missing cache headers 17 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:** 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:** 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:** 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.
