Coding agents moved my bottleneck. Writing the code got fast. Understanding what the agent actually did became the slow part.
The evidence already exists. Claude Code, Codex CLI, and Hermes Agent all keep full session records on disk (~/.claude/projects, ~/.codex/sessions, and ~/.hermes): every tool call, every error, every retry, every subagent and delegation. Almost nobody reads them, because a single session runs to thousands of lines of JSONL.
So I built rungraph. Free, MIT licensed, no paid tier.
