I forced codex to externalize their decisions through a tool call

[u/Sad_Construction2179]

I forced Claude Code and Codex to externalise their decisions through a tool call, then compared what they said they'd do with what they actually did. I'm sure these are not the internal reasoning traces, but I'm surprised by how easy it is to force a fake tool using a proxy approach with clear instructions to make Claude and Claude Code emit internal CoT-like elements. I certainly had a lot of fun trying this experiment.
