EvanFlow
TDD-first workflow framework that turns Claude Code into a disciplined dev team
The Panel's Take
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.

“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.”
“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 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.”
“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.”
