5 open checks (3 failing) can be handed to an AI agent: D2, C1, C3, B2, E4. Pick one route — each returns the full, check-by-check instructions.

Option A — Agent Skill (any runtime)

npx add-skill https://aiscan.site/aiscan-skill.json

Then ask your agent: “Fix the failing AI readiness checks for https://prowaterproofsg.com/”.

Option B — Claude Code (CLAUDE.md)

curl -o CLAUDE.md https://aiscan.site/CLAUDE.md

Drop it in your project root, then ask Claude Code to fix the failing AIScan checks.

Option C — MCP client

https://aiscan.site/api/mcp

Tools: scan_website, get_fixes, get_grade. Call get_fixes { "url": "https://prowaterproofsg.com/" }.

Option D — REST API

curl -s 'https://aiscan.site/api/public/scan?url=https%3A%2F%2Fprowaterproofsg.com%2F'

Returns every check with its complete fix guide.

Verify: Re-scan at https://aiscan.site after applying fixes, or run npx aiscan-cli https://prowaterproofsg.com/. Individual checks that need a specific probe list it in their own guide.

# WordPress agent-readiness fixes

Site: https://prowaterproofsg.com/
Platform: wordpress (99% confidence)
AIScan score: 59/100 — Level 3 (Governed)
Rubric: v2026.08.2

Apply these in WordPress admin or via a small mu-plugin. Prefer the plugin route so changes survive theme updates.

## Failing checks
- **[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 publish /index.md.
- **[B2] Explicit AI bot rules** — FAIL
  - Evidence: 0 known AI agent(s) addressed in robots.txt
  - Fix: Add explicit allow/deny rules for GPTBot, ClaudeBot, PerplexityBot, Google-Extended, etc.
- **[D2] XML sitemap** — FAIL
  - Evidence: no /sitemap.xml or /sitemap_index.xml resolved
  - Fix: Publish /sitemap.xml and reference it in robots.txt.
- **[C3] Structured HTML (title, meta, JSON-LD, single H1)** — PARTIAL
  - Evidence: h1: 0, title: true, meta description: false, JSON-LD: false
  - Fix: Ensure a single <h1>, <title>, meta description, and schema.org JSON-LD.
- **[E4] HTTPS & canonical host** — PARTIAL
  - Evidence: final origin https://prowaterproofsg.com · http:// upgrades to https · www.prowaterproofsg.com serves its own copy (duplicate origin) · no HSTS header
  - Fix: Serve the site over HTTPS, 301-redirect http:// to https://, and redirect the www/apex variant to a single canonical host so agents don't index two copies of every URL.

## How to apply on WordPress
- **robots.txt / llms.txt**: drop static files at the web root (FTP / file manager), or use a small plugin that filters `robots_txt` and registers a rewrite rule for `/llms.txt`.
- **Markdown negotiation**: a mu-plugin hooking `template_redirect` can return `get_the_content()` as Markdown when `Accept: text/markdown` is present.
- **AI bot rules**: extend the robots.txt block above with user-agents (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended, Bytespider, CCBot…).
- **MCP / Agent Skills cards**: place JSON files under `/.well-known/` via the same mu-plugin.

Avoid bloated SEO plugins — a single ~60-line mu-plugin covers all of this.

How this score is calculated

Every check earns points against a weight. We divide the points you earned by the points that actually apply to a WordPress — so checks that don't apply never drag you down.
