About
AgentLens is an open-source CLI wrapper for the Codex coding-agent CLI that records a run's commands, file diffs, and token usage into a local timeline, then lets a developer replay it or compare two runs side by side to see where they diverged. It can export a redacted, single-file HTML artifact of a session for sharing in a pull request or with a teammate without exposing secrets.
At a glance
AgentLens records a Codex run and lets you replay commands, patches and likely file reads or compare two runs. It is worth trying when a repeat prompt produces a different result and the terminal log makes the divergence hard to find.
Good fit
Developers investigating coding-agent regressions or preparing evidence for a teammate.
Consider something else when
Use an authoritative trace when you need proof of exactly which files a run read.
Start here
Run a harmless prompt twice in a scratch Git repository. Compare the earliest captured difference, then inspect the exported report before sharing it.
Cost and requirements
MIT-licensed. The documented setup needs Node.js 20 or later, Git and an authenticated Codex CLI.
Limits to know
Some reads are inferred. Local session artifacts keep original data, while exports redact by pattern. Review an export for secrets before publishing it.

Why it made the leaderboard
Records and replays Codex agent sessions, letting developers diff two runs to see exactly where they diverged and export a redacted, shareable HTML report for code review.
