Agentfdr debugs Claude Code with per-turn timelines

As AI coding agents become more autonomous, understanding why they fail or loop infinitely is increasingly challenging. Agentfdr solves this by turning existing logs into actionable insights without requiring heavy setup. It visualizes Claude Code's per-turn timelines and automatically flags infinite loops, token burns, and error streaks. The tool includes a live watch mode, plan-usage tracking, and cost estimation while operating entirely locally with zero instrumentation required.
