## Failing checks (sorted by weight)
- **[C1] Markdown content negotiation** — FAIL
  - Evidence: Accept: text/markdown → 200 (text/html; charset=UTF-8)
  - Fix: Serve text/markdown when the client sends Accept: text/markdown, or expose /path/index.md.
- **[P1] API Catalog (RFC 9727)** — FAIL
  - Evidence: 404 at /.well-known/api-catalog
  - Fix: Publish /.well-known/api-catalog linking to your OpenAPI descriptions.
- **[P4] OAuth discovery metadata** — FAIL
  - Evidence: auth-server: 403, protected-resource: 403
  - Fix: Publish RFC 8414 / RFC 9728 metadata at the /.well-known/oauth-* endpoints.
- **[D3] Link header for discovery** — FAIL
  - Evidence: no Link response header
  - Fix: Add a Link header with rel="api-catalog" or rel="describedby".

## General guidance
- Static-first: `robots.txt`, `llms.txt`, `/.well-known/*` JSON cards.
- Markdown negotiation: serve `text/markdown` when requested via `Accept` header or `?format=md`.
- Bot access: explicit allow/deny per AI user-agent (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended, Bytespider, Amazonbot, CCBot, meta-externalagent, cohere-ai, Diffbot).
- Capabilities: publish an MCP server card and (optionally) an Agent Skills manifest even if the runtime isn't live — discovery first.
- Re-scan at aiscan.site after deploying.

    What we found

    no Link response header

    How to fix it

    Add a Link header with rel="api-catalog" or rel="describedby".

    1.⚡ Fix automatically with AIScan

    The fastest way to apply this fix is using AIScan's own agent tooling — it gives any AI coding assistant machine-readable instructions for this exact check. **Option A — Claude Code skill** 1. Download `CLAUDE.md` from https://aiscan.site/CLAUDE.md and drop it into your project root. 2. Ask Claude Code: *"Fix the failing AIScan check for <your-url>"* — it will read the skill, call our API, and apply the fix. **Option B — MCP (any MCP-compatible agent: Claude Desktop, Cursor, etc.)** - Endpoint: `https://aiscan.site/api/mcp` - Tools: `scan_website`, `get_fixes`, `get_grade` - Call `get_fixes` with your URL for machine-readable fix instructions. **Option C — REST API (any tool / script)** ``` GET https://aiscan.site/api/public/scan?url=YOUR_URL ``` Returns the full report including failing checks and fix details. Then re-scan at https://aiscan.site to verify.

    2.Add a Link response header

    Set this header on your homepage and/or root document. Most CDNs (Cloudflare, Vercel, Netlify) support response-header rules.

    3.Example
    Link: </.well-known/api-catalog>; rel="api-catalog"
    4.Verify

    After deploying, re-scan at https://aiscan.site. You can also test with `curl -I` or `curl` directly.

    What we found

    Accept: text/markdown → 200 (text/html; charset=UTF-8)

    How to fix it

    Serve text/markdown when the client sends Accept: text/markdown, or expose /path/index.md.

    1.⚡ Fix automatically with AIScan

    The fastest way to apply this fix is using AIScan's own agent tooling — it gives any AI coding assistant machine-readable instructions for this exact check. **Option A — Claude Code skill** 1.

Then re-scan at https://aiscan.site to verify.

    2.Serve text/markdown on Accept negotiation

    When a client sends `Accept: text/markdown`, return a markdown rendering of the same content. The simplest path is to publish parallel `.md` files (e.g. `/about` → `/about.md`) and rewrite based on the Accept header.

    3.Test it
    curl -H "Accept: text/markdown" https://yoursite.com/
    4.Verify

    After deploying, re-scan at https://aiscan.site. You can also test with `curl -I` or `curl` directly.
