<p><strong>AJ Agent Crawl Optimizer</strong> is a thin compatibility layer that teaches your site to speak the languages AI agents already use to discover and consume web content. It publishes machine-readable manifests at well-known URLs, serves clean Markdown when an AI requests it, and declares your AI-usage preferences — all without changing anything for human visitors.</p>
<p>Each capability is a separate toggle under <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> AJ Agent Crawl Optimizer</strong> and ships <strong>opt-in</strong> (everything starts off). On first activation, a one-time <strong>Quick Setup wizard</strong> suggests sensible defaults based on your environment (for example, it skips JSON-LD when an SEO plugin is detected so you don’t get duplicate structured data).</p>
<h4>Discovery — help agents find what your site offers</h4>
<ul>
<li><strong>API Catalog</strong> (RFC 9727) — <code>/.well-known/api-catalog</code> linkset advertising your REST API, plus a <code>Link: rel="api-catalog"</code> header on every response so agents discover it from any URL.</li>
<li><strong>MCP Server Card</strong> (SEP-1649 draft) — <code>/.well-known/mcp/server-card.json</code> describing the site to MCP-aware agents.</li>
<li><strong>Agent Skills Index</strong> (RFC v0.2.0) — <code>/.well-known/agent-skills/index.json</code> listing six skills (search, posts, pages, media, categories, tags) plus per-skill <code>SKILL.md</code> artifacts with verifiable sha256 digests.</li>
<li><strong>llms.txt</strong> (per llmstxt.org) — <code>/llms.txt</code> curated, LLM-readable index of your top pages and recent posts, with a Discovery section auto-linking every other plugin endpoint.</li>
<li><strong>IndexNow</strong> — non-blocking ping to Bing and Yandex on every post publish so search engines re-crawl within minutes.</li>
</ul>
<h4>Presentation — format content for agents</h4>
<ul>
<li><strong>Markdown Negotiation</strong> — when a request includes <code>Accept: text/markdown</code>, the page is served as clean Markdown with <code>X-Markdown-Tokens</code> for context budgeting. Browsers (which send <code>text/html</code>) are completely unaffected.</li>
<li><strong>JSON-LD Schema</strong> — Schema.org structured data: WebSite, Organization, Article, BreadcrumbList, and auto-detected FAQPage. Logo resolved from your theme’s custom logo or site icon.</li>
<li><strong>OpenAPI 3.0.3</strong> — <code>/?format=openapi</code> returns a complete spec generated dynamically from <code>rest_get_server()</code>, including plugin-registered REST routes.</li>
<li><strong>WebMCP Tools</strong> — registers four tools (search, posts, pages, site info) via <code>navigator.modelContext.provideContext()</code> for browsers that support the W3C WebMCP draft.</li>
</ul>
<h4>Declarations</h4>
<ul>
<li><strong>Content-Signals</strong> — appends a <code>Content-Signal: ai-train=no, search=yes, ai-input=no</code> directive to robots.txt declaring your AI-usage preferences (per contentsignals.org). Composes with Yoast/Rank Math/AIOSEO — their additions are preserved, our line lands at the very end.</li>
</ul>
<h4>Why use it</h4>
<ul>
<li><strong>No conflicts with your SEO plugin.</strong> JSON-LD auto-suppresses when Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework, Slim SEO, Squirrly SEO, Schema Pro, or SASWP is active.</li>
<li><strong>Multisite-aware.</strong> Every endpoint also resolves at <code>/{subsite}/...</code> paths automatically.</li>
<li><strong>Cached.</strong> OpenAPI is cached for a day, llms.txt for an hour, with proper invalidation on plugin activation, theme switch, post changes, and setting toggles.</li>
<li><strong>Performance-conscious.</strong> Markdown handler runs at <code>PHP_INT_MAX</code> priority so it doesn’t break object-cache flushes or Query Monitor. IndexNow pings are non-blocking.</li>
<li><strong>Extensible.</strong> Nine filter hooks let you customize skills, schemas, capabilities, and content. See “For Developers” below.</li>
<li><strong>Accessible.</strong> Score-card SVG has dynamic <code>aria-label</code>, copy buttons announce success via <code>aria-live</code>, decorative arrows hidden from screen readers via CSS pseudo-elements.</li>
</ul>
<h4>For developers</h4>
<p>The plugin exposes nine filter hooks for extension. Examples:</p>
<pre><code>add_filter( 'ajaco_required_capability', function () { return 'edit_posts'; } );
</code></pre>
<p>Delegate plugin access to a non-admin role.</p>
<pre><code>add_filter( 'ajaco_skill_definitions', function ( $skills ) { return $skills + [ 'products' => [ 'type' => 'information-retrieval', 'description' => 'WooCommerce products', 'endpoint' => rest_url( 'wc/v3/products' ) ] ]; } );
</code></pre>
<p>Register custom skills that ship in the Agent Skills Index and are served as SKILL.md artifacts with verifiable sha256 digests.</p>
<pre><code>add_filter( 'ajaco_content_signal', function () { return 'ai-train=yes, search=yes, ai-input=yes'; } );
</code></pre>
<p>Customize the Content-Signal directive (e.g. permit AI training).</p>
<p>Other hooks: <code>ajaco_api_catalog_linkset</code>, <code>ajaco_mcp_server_card</code>, <code>ajaco_json_ld_graph</code>, <code>ajaco_openapi_spec</code>, <code>ajaco_llms_txt_content</code>, <code>ajaco_active_seo_plugin</code>. The settings page’s Help tab <span aria-hidden="true" class="wp-exclude-emoji">→</span> For Developers lists all of them with descriptions.</p>
<h3>External services</h3>
<p>This plugin connects to one external service, and only when the corresponding feature is explicitly enabled by the site administrator.</p>
<h4>IndexNow (api.indexnow.org)</h4>
<p>What it is and what it’s used for: IndexNow is an open protocol (originally from Microsoft Bing and Yandex) that lets sites notify search engines the moment a URL is published or updated, so search engines can re-crawl within minutes instead of days.</p>
<p>When data is sent: only when the <strong>IndexNow</strong> feature toggle is turned on AND an IndexNow API Key is configured on the settings page. In that case, every time a post of a public post type transitions to the <code>publish</code> status, the plugin fires a single non-blocking HTTPS POST to <code>https://api.indexnow.org/indexnow</code>.</p>
<p>What data is sent: the request body is a JSON document containing exactly three fields — your site’s host (e.g. <code>example.com</code>), your IndexNow API key (which you generated yourself at Bing Webmaster Tools), and the permalink URL of the post that was just published. No visitor information, IP addresses, user-agents, or post content is sent.</p>
<p>If the IndexNow feature toggle is off (the default), the plugin makes no outbound network requests of any kind.</p>
<p>This service is provided by Microsoft (Bing) and the IndexNow project. Their terms and privacy policies apply:</p>
<ul>
<li>IndexNow protocol documentation: https://www.indexnow.org/documentation</li>
<li>IndexNow FAQ and terms: https://www.indexnow.org/faq</li>
<li>Microsoft Bing Webmaster Guidelines : https://www.bing.com/webmasters/help/webmaster-guidelines-30fba23a</li>
<li>Microsoft Privacy Statement: https://www.microsoft.com/en-us/privacy/privacystatement</li>
</ul>
<h3>Privacy</h3>
<p>AJ Agent Crawl Optimizer stores data <strong>only on your own server</strong> — there is no telemetry, no analytics, and no third-party logging. Specifically:</p>
<h4>Local data</h4>
<ul>
<li>Plugin <strong>option rows</strong> in the WordPress options table store toggle states and the IndexNow API Key (stored as plain text — keep your database secure).</li>
<li><strong>Transients</strong> cache the OpenAPI document and llms.txt body. These are deleted on plugin uninstall.</li>
<li>No request data, IP addresses, User-Agents, or visitor information is recorded by the plugin.</li>
</ul>
<h4>Outbound network calls</h4>
<p>The plugin makes exactly <strong>one</strong> outbound HTTP request, and only when explicitly enabled:</p>
<ul>
<li><strong>IndexNow</strong> — when the IndexNow toggle is on and a key is configured, the plugin sends a non-blocking POST to <code>https://api.indexnow.org/indexnow</code> on every post publish. The payload contains the site host, the IndexNow key, and the URL of the published post (no visitor data).</li>
</ul>
<p>If the IndexNow toggle is off (the default), the plugin makes zero outbound network requests. All other features (manifests, JSON-LD, robots.txt) only respond to incoming HTTP requests; they never call out.</p>
<h4>Cookies</h4>
<p>The plugin does not set any cookies.</p>
<h4>Uninstall</h4>
<p>When the plugin is <strong>deleted</strong> (not just deactivated), all plugin options, the IndexNow key, and all transients are removed from the database. Multisite networks have every site cleaned in turn.</p>
