EvanFlow is an open-source framework that wraps Claude Code in a structured software development workflow. Built around a brainstorm → plan → execute → test → iterate loop, it adds human approval checkpoints between each stage so the AI never autonomously commits or deploys. Think of it as giving Claude Code a senior engineer's instincts: it stops before dangerous git operations, validates test assertions, detects context drift, and flags the five failure modes that routinely derail LLM-generated code. The project ships 16 integrated skills and two custom subagents for parallel development, plus a git guardrails hook that physically blocks risky operations like force-pushes or wholesale file deletions. Every iteration runs a Five Failure Modes checklist — hallucinated actions, scope creep, cascading errors, context loss, and tool misuse — before proposing the next step. Visual UI changes are verified via a headless browser before the developer signs off. EvanFlow fills a real gap: Claude Code is powerful but undisciplined by default. EvanFlow imposes structure without removing control. It's MIT-licensed, ships via npm CLI or Claude Code's plugin marketplace, and requires no backend — just Claude Code access and jq.

IsItAgentReady is a free web scanner that audits any URL for AI agent readiness across 36 checkpoints organized in five categories: robots.txt compliance (covering all 13 major AI crawler bots), structured data (17 Schema.org types), llms.txt implementation, MCP endpoint detection, and OAuth/agentic commerce readiness. Each category gets a letter grade with specific, actionable fix instructions. The tool was built by a two-person team responding to a growing pain point: as AI agents replace search engine crawlers as the primary way content is discovered and consumed, most websites are not configured to be agent-accessible. A site might have perfect SEO but actively block Claude, GPT, or Perplexity crawlers in its robots.txt — effectively invisible to the AI-driven web. IsItAgentReady surfaces these gaps in about 15 seconds. It also ships as an MCP server, making it usable directly from Claude Code, Cursor, Copilot, or any MCP-compatible environment: run a scan from the terminal and get structured results without leaving your editor. The project is positioned as "Google PageSpeed Insights for the agentic web" — a framing that resonated on Hacker News where it appeared as a Show HN with strong engagement.
Reviewer scorecard
“This is exactly what Claude Code needed. The git guardrails hook alone is worth installing — I've seen too many agents nuke a working branch with a confident `git reset --hard`. EvanFlow's 'conductor not autopilot' philosophy maps perfectly to how good engineers actually want to use AI: fast on the mechanical stuff, slow on the decisions that matter.”
“The MCP server integration is the killer feature — I ran it directly from Claude Code on three client sites and had actionable fixes within a minute. The robots.txt check alone is worth the trip: most sites are blocking AI crawlers without realizing it.”
“Sixteen skills and two subagents sounds like a lot of complexity layered on top of a tool that's already opinionated. The approval checkpoints are nice in theory, but developers under deadline will click through them reflexively — at which point you've just added friction without safety. Also requires Claude Code, which is not cheap.”
“The 36 checkpoints sound comprehensive but several are aspirational standards that haven't been widely adopted yet — like MCP endpoint detection and agentic commerce. You risk over-engineering your site for agent features that most users will never use in 2026.”
“The real signal here isn't EvanFlow itself — it's that the community is already building governance layers on top of AI coding agents. The 62% error rate in LLM-generated test assertions that EvanFlow cites is a sobering number. Projects like this show that safe AI-assisted development needs to be engineered, not assumed.”
“This is the 2026 equivalent of Google's mobile-friendly test from 2015. Sites that fail that test eventually lost traffic — sites that fail agent-readiness checks will lose AI-driven discovery. IsItAgentReady is the early warning system before that penalty is enforced.”
“If you're a solo builder or small team shipping fast, EvanFlow's vertical-slice TDD mode is a game-changer. It keeps the AI focused on one working slice at a time rather than hallucinating an entire architecture. The visual UI verification via headless browser is a thoughtful touch that saves embarrassing regressions.”
“The graded report with step-by-step fix workflows is genuinely well-designed — it's the kind of output you can hand directly to a developer or a client without translation. Clean, actionable, and free.”
