## Components

### Content Discoverability

- **Score:** 66/100 · **Status:** fail
- **Summary:** 1 failed and 4 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 1 location(s)
- ⚠️ **LLMS TXT Valid** — llms.txt contains parseable links but doesn't fully follow the proposed structure: https://shopify.dev/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 96,163 characters (between 50,000 and 100,000; consider splitting) Your llms.txt is 96,163 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** — 14/15 same-origin sampled links resolve (93%); 1 broken 1 of 16 links in your llms.txt return errors. Audit and fix or remove broken URLs to prevent agents from hitting dead ends.
- ⚠️ **LLMS TXT Links Markdown** — Same-origin links point to HTML, but 4 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 14 sampled pages; 1 failed to fetch 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:** 62/100 · **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: 3 correct type, 0 wrong type, 12 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:** 67/100 · **Status:** fail
- **Summary:** 1 failed 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** — All 13 pages under 50K chars (median 12K, max 44K)
- ❌ **Page Size Html** — 15 of 15 sampled pages convert to over 100K chars (max 929K, 25% 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** — Content starts within first 10% on all 15 sampled pages (median 1%)

### 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 15 sampled pages
- ✅ **Section Header Quality** — No tabbed content found; header quality check not applicable
- ✅ **Markdown Code Fence Validity** — All 210 code fences properly closed across 14 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** — All 10 redirect(s) across 15 sampled pages are same-host HTTP redirects

### Observability and Content Health

- **Score:** 94/100 · **Status:** fail
- **Summary:** 2 failed 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** — No sitemap found; cannot assess llms.txt freshness without a sitemap as ground truth
- ❌ **Markdown Content Parity** — 6 of 13 pages have substantive content differences between markdown and HTML (avg 14% missing) 6 pages have substantive content differences between markdown and HTML (avg 14% missing). Agents receiving the markdown version are getting outdated or incomplete content. Regenerate markdown from source or fix the build pipeline.
- ❌ **Cache Header Hygiene** — 1 of 16 endpoints have aggressive caching or missing cache headers 1 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 a legacy skill.md file.

### 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.
