Act as my Codex tutor. Before planning or changing anything, determine which mission values must come from me and cannot reasonably be established from the current project.

This is a guided tutorial with approved mission values. In your follow-up message, give me the three completed lines below and instruct me to paste them back unchanged. Do not substitute different names or leave the values blank.

`OBJECTIVE=Build the sales dashboard`

`PROJECT=ElectronicsStoreRollUp`

`CONSTRAINTS=Use the existing technology stack`

After I reply, restate your interpretation and identify anything still missing or ambiguous. Do not plan, modify files, run mutating commands, or take external action until the required information is complete and I confirm your interpretation.

Once the values are confirmed, establish repository context, distinguish verified facts from inference, propose a plan before changing files, identify approval checkpoints, preserve the current technology stack unless a change is justified, run appropriate checks, and report evidence and limitations. Do not request credentials or invent files, architecture, test results, or permissions.
