Level 10 Practice: Design an Operating Model for Multiple Agents
About 5 minutes
About This Tutorial
Section titled “About This Tutorial”For the concepts and completion standards, first read Codex Levels 0-10.
Before adding more agents, define role separation, quality standards, cost limits, and shutdown procedures. Level 10 is about human-governed infrastructure, not removing people.
What You Will Complete
Section titled “What You Will Complete”You will produce an agent platform design with evaluation, audit, and improvement. The goal is not the amount of work; it is a reproducible Level 10 delegation boundary and completion check.
Step 1: Set the Boundary
Section titled “Step 1: Set the Boundary”Before handing work to Codex, state the goal, scope, exclusions, and completion criteria. Adapt this prompt to your project.
Design a platform for operating multiple Codex workflows. Tabulate roles, least privilege, inputs and outputs, evaluation metrics, audit evidence, cost limits, stop conditions, and the improvement loop.Check: Continue only when Codex can restate the scope and unresolved questions before acting.
Step 2: Practice
Section titled “Step 2: Practice”- Separate responsibilities and permissions for planning, implementation, review, and security.
- Define measures for success, rework, review findings, elapsed time, and cost.
- Design a feedback loop that turns failures into rules, skills, and tests, plus a shutdown procedure.
Keep the scope stable and inspect the output or diff after each stage.
Step 3: Verify Completion
Section titled “Step 3: Verify Completion”You are done when responsibilities are explicit, quality or budget breaches stop execution, and results feed measurable improvements.
Record the actions performed, supporting evidence, and anything not verified. Also record why work stopped when a condition was not met.
Troubleshooting
Section titled “Troubleshooting”Codex exceeded the requested scope
Section titled “Codex exceeded the requested scope”Stop the task and inspect the diff. Add explicit owned files and exclusions to the prompt, then rerun only the approved scope.
Completion is difficult to judge
Section titled “Completion is difficult to judge”Replace vague criteria such as “implement it” with observable files, commands, pages, or review results.
Next Step
Section titled “Next Step”This completes Levels 0-10. Evaluate operational results and continuously improve only the levels your projects need.
