DevRadar

A dev-tools company's documentation is now read by AI coding agents as well as by developers. When the docs block an agent's user agent, render only with JavaScript, or have no llms.txt or OpenAPI spec an agent can find, the agent works from guesses. The team that owns the docs rarely sees it happen.

DevRadar takes one input, a docs URL, and scans the public surface the way an agent, a competitor and a developer would. The free scan runs stages 1 and 2 today:

• Docs. Reachability, redirects, sitemap coverage, how much of each page needs JavaScript to read, and whether a quickstart and code samples can be found.
• Agent readiness. robots.txt policy for agent crawlers, whether the docs answer an agent's user agent differently from a browser's, llms.txt, OpenAPI discoverability, and whether an advertised MCP server answers.

Stage 2 is the earlier AgentReady scanner, folded in. agentready.rexstjohn.com now redirects here. The remaining stages, competitors, events, personas, targeting and the assembled report, are rolling out.

Paid plans add a weekly re-scan:

• Watch, $149 a month. Weekly agent and docs scan with change alerts, and a weekly sample-code test run.
• Radar, $599 a month. Adds a weekly buzz scan, events and CFPs for your regions, and three tracked competitors.
• Program, $2,500 a month. Unlimited competitors, a monthly working session and a maintained 3, 6, 9 and 12 month roadmap.

Plans are arranged by email for now. There is no checkout yet.

Every finding carries the raw artifact it came from, the actual status line, headers or snippet, or it is dropped. A check that cannot run is reported as unknown, never as a failure, because a false positive in a report forwarded to an engineering lead cannot be taken back.

The first finding is never paywalled. If the scan sees a 403 to ClaudeBot, the free report shows the 403. Paid plans buy breadth and recurrence, not the first fact.

There is no score, grade or leaderboard, and reports are unlisted. A score starts an argument about methodology and moves the conversation off the finding that mattered. The cost is a report that is harder to summarize in one line.

The scanner is polite by design. It makes at most 60 requests per domain per day across the whole platform, competitor domains included, and it does nothing that looks like a security test.
