Tableau Refresh Failure Agent with Codex
The way this agent goes wrong is by helping too much: turning an ODBC string into a claim that the warehouse password expired, and sending a data engineer to the wrong place before breakfast. Codex is at its best when the instruction is to move a value rather than interpret it, and every error string in this template has to arrive unedited.
Watch it work before it's live
Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.

Why Codex for this agent
Driver codes survive the trip
A number like 39001 buried in the message is what a vendor search matches on. Carrying a string through untouched is mechanical work, and mechanical is precisely what you want.
Cause is not in the payload
The job record says what failed and never why. Writing only what the error itself says is the line the entire usefulness of the note depends on.
Before you fork
Does querying the whole site on every failure hammer Tableau?
It runs on failed jobs rather than on a schedule, and the extra work is one datasource listing per failure. A night when eight extracts drop together is eight runs each doing that listing, which is small next to the refreshes themselves. On a site with thousands of datasources, scope the escalation rules to the projects you actually watch.
