can you get my first codex message to codex cli and check when it was made, so I can estimate total time it took to implement
I’ll inspect the local Codex CLI history/config to identify the earliest message associated with this project, then report its timestamp and any ambiguity. I’m using the OpenAI docs skill because this involves Codex CLI’s local session storage, plus the always-required writing cleanup skill.
The skill’s official-docs lookup requirement does not help identify a private local timestamp, so I’m moving to the authoritative source here: your local Codex session logs. I’ll avoid printing message bodies beyond what’s needed to match this repository.
I found the start of the assignment thread. The session began from the parent assignments directory, which is why an exact working-directory search initially missed it. I’m checking the repository’s first and latest commit times too, so the estimate can distinguish conversation time from actual implementation span.
Your first Codex CLI message about this assignment was sent on September 18, 2026 at 12:14:28 PM Chile time:
“Ok, let's do this assignment. It says 2-6 hours…”
Useful duration estimates:
I’d report about 3 hours 10 minutes total, since that includes the implementation, verification, benchmarking, and final hardening work without counting this administrative check.
