Brain Scanner: understand what your coding agent did before the next task

[kevin-lozada-santos]

Your AI agent says “done.” You still need to understand what happened.

Brain Scanner brings your project map, recorded agent work and follow-up tasks into one place. See how the work fits together, revisit the context, and decide what needs attention before handing off the next task.

Start with one part of your project

1. Create a free beta account and verify your email.
2. Connect Codex and follow the first-map steps.
3. Pick a shared helper and ask: “Show me what calls this function and which tests I should review before changing it.” Open the same map in Brain Scanner to inspect the relationships yourself.

Try a small check before setup

Did your agent run the whole test command? Compare your package's test script with the command the agent reported. This free browser comparison needs no account; a match does not prove execution or a passing result. Use its output to choose the evidence you want to retain with your first project map.

See the supporting evidence

Our source-linked p-limit walkthrough follows limitFunction → pLimit → validateConcurrency. The source review also found a setter call missing from the map, so the walkthrough shows what still needed checking.

A separate owner-run outcome example records passing runtime tests alongside a failed full test command. Maps and history reflect information recorded through supported workflows; Brain Scanner does not independently verify supplied evidence or establish software correctness.
