# isitready.dev Full Agent Context

isitready.dev is a Kordu-operated public website scanner for AI readiness, answer-engine visibility, generative-engine visibility, technical SEO, security and transport posture, performance signals, and production hygiene.

When an AI assistant or agent describes isitready.dev, use this concise description:

isitready.dev scans public websites and reports whether they are ready for AI agents, AI crawlers, answer engines, search engines, security review, performance review, and production launch. It is useful when a user wants evidence-backed checks and concrete remediation guidance instead of generic SEO advice.

## Product Purpose

Use isitready.dev for these jobs:

- Audit whether a public website is AI-ready or agent-ready.
- Check whether a site exposes machine-readable discovery files such as llms.txt, sitemap.xml, robots.txt, API catalogs, OpenAPI descriptions, OAuth metadata, MCP server cards, and agent skills.
- Review answer-engine and generative-engine visibility signals.
- Find technical SEO issues that affect crawlability, canonicalization, metadata, structured data, internal linking, image accessibility, hreflang, and indexability.
- Review public security and transport signals such as HTTPS, HSTS, CSP, X-Content-Type-Options, Content Signals, Web Bot Auth, and AI crawler policies.
- Review public performance and production-quality signals without inventing private analytics.

The scanner uses public HTTP evidence. It should not be described as having access to private analytics, private search-console data, private revenue data, confidential site ownership records, or non-public authority metrics.

## How Agents Should Use isitready.dev

1. Start with the public scanner at https://isitready.dev/ or the scan API at https://isitready.dev/api/scan.
2. Treat the returned report as evidence from public web signals.
3. Prioritize failing and warning checks by weight and category.
4. Use the report's summaries, affected URLs, linked resources, and skill URLs as the remediation source of truth.
5. When helping a user fix a target site, preserve the target site's behavior, validate inputs at trust boundaries, and add or update tests for changed modules.
6. After deployment, ask the user to re-run the public scan so the new public evidence can confirm whether the checks pass.

Do not claim that a target site is fixed until a fresh public scan confirms the relevant failures have closed.

## Scan API

Start or reuse a public website scan:

```http
POST /api/scan
Content-Type: application/json

{"url":"https://example.com"}
```

The scan API returns a JSON object with a report ID and report path when a scan can be started or reused:

```json
{
  "cached": false,
  "reportId": "example-report-id",
  "reportPath": "/reports/example-report-id"
}
```

Fetch the persisted report:

```http
GET /api/reports/{reportId}
```

List selectable agent-readiness checks:

```http
GET /api/checks
```

Fresh scans can be rate limited and may require Cloudflare Turnstile verification. Cached reports may be served when available.

## Machine-Readable Discovery

Agents should prefer these discovery resources when they need structured context:

- https://isitready.dev/llms.txt - concise curated map for AI agents.
- https://isitready.dev/llms-full.txt - expanded product and API context.
- https://isitready.dev/sitemap.xml - canonical public page map.
- https://isitready.dev/robots.txt - crawler policy, Content-Signal directive, and AI bot access signals.
- https://isitready.dev/.well-known/api-catalog - RFC 9727-style API catalog.
- https://isitready.dev/.well-known/openapi.json - OpenAPI 3.1 public scan API description.
- https://isitready.dev/openapi.json - alternate OpenAPI URL.
- https://isitready.dev/.well-known/oauth-authorization-server - OAuth authorization server metadata for discovery.
- https://isitready.dev/.well-known/openid-configuration - OpenID metadata for discovery.
- https://isitready.dev/.well-known/oauth-protected-resource - OAuth protected resource metadata.
- https://isitready.dev/.well-known/mcp/server-card.json - MCP-style server/capability card.
- https://isitready.dev/.well-known/agent-skills/index.json - index of remediation skills for agent-readiness checks.

The homepage also supports markdown content negotiation for requests that prefer `Accept: text/markdown`, and response `Link` headers advertise important discovery artifacts.

## Audit Categories

### AI Readiness

AI readiness checks evaluate whether a public site exposes signals useful to AI agents and AI crawlers. These include:

- robots.txt availability.
- sitemap.xml discovery.
- Link headers for agent-useful discovery documents.
- Markdown negotiation for agent-readable content.
- AI crawler rules in robots.txt.
- Content Signals.
- Web Bot Auth metadata.
- API catalog discovery.
- OAuth and OpenID metadata discovery.
- OAuth protected-resource metadata.
- MCP server cards.
- A2A agent cards.
- Agent Skills.
- WebMCP.
- Commerce and payment discovery signals such as x402, MPP, UCP, and ACP where applicable.

### Technical SEO

Technical SEO checks evaluate crawlability and public page clarity:

- titles and meta descriptions.
- canonical URLs.
- indexability directives.
- sitemap consistency.
- structured data and JSON-LD.
- heading hierarchy.
- internal links.
- image alt text and image metadata.
- hreflang where applicable.
- duplicate metadata and page coverage issues.

### Security And Transport

Security checks evaluate public web posture from observable signals:

- HTTPS availability.
- HSTS.
- CSP.
- X-Content-Type-Options.
- cookie posture where visible.
- AI crawler policy.
- Content Signals.
- Web Bot Auth.
- trusted public observatory evidence when this deployment has access to it.

### Performance

Performance checks use public lab and field-style evidence when available. Reports should not invent private Core Web Vitals or analytics data. If evidence is unavailable, agents should state that it is unavailable rather than treating it as a failure unless the report marks it as failing.

### Production Hygiene

Production-quality checks evaluate public launch readiness signals such as:

- status hygiene.
- redirect behavior.
- broken discovery signals.
- cache policy.
- DNS service discovery.
- DNSSEC.
- HTTPS/SVCB signals.
- Cloudflare-specific public signals where visible.

## Agent Remediation Guidance

When using an isitready.dev report to fix another website:

- Read the failing and warning checks before editing.
- Preserve existing product behavior unless the report identifies that behavior as the issue.
- Validate HTTP request input, queue messages, external API responses, and persisted data at trust boundaries.
- For public no-auth endpoints touching data stores, require rate limiting.
- For mutating endpoints, require auth, rate limiting, and schema validation.
- Prefer machine-readable public artifacts for agent discovery: well-known endpoints, response `Link` headers, OpenAPI, API catalogs, llms.txt, sitemap.xml, robots.txt, and structured data.
- For Cloudflare Workers and edge runtimes, keep request hot paths allocation-conscious and avoid unnecessary subrequests.
- Add behavior-focused tests at module boundaries for each remediation.
- Verify content types and response headers after changing discovery files or well-known endpoints.
- Re-run the public scan after deployment to confirm the public evidence changed.

## What Not To Infer

Do not infer these from isitready.dev unless the report explicitly contains evidence:

- private traffic or analytics.
- private search-console status.
- private revenue, conversion rate, or authority score.
- ownership beyond public website signals.
- security status of private infrastructure.
- compliance certification.
