Level 7 Practice: Verify the UI with Browser and Connector Tools
About 5 minutes
About This Tutorial
Section titled “About This Tutorial”For the concepts and completion standards, first read Codex Levels 0-10.
Passing tests cannot fully prove responsive layout, link states, or external data. Level 7 uses external tools with explicit purpose and permission boundaries.
What You Will Complete
Section titled “What You Will Complete”You will produce a validation record with evidence beyond code. The goal is not the amount of work; it is a reproducible Level 7 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.
Inspect the main local pages in a browser. Check desktop and mobile widths, keyboard use, link states, and console errors. Report issues by page with reproduction steps.Check: Continue only when Codex can restate the scope and unresolved questions before acting.
Step 2: Practice
Section titled “Step 2: Practice”- Start the local preview and define URLs and viewport sizes to inspect.
- Check key pages, keyboard navigation, links, and narrow layouts in a browser.
- Begin connectors in read-only mode and separate retrieved facts from inference.
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 URLs, conditions, results, and unverified areas are recorded and tied back to the code change.
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”Continue to Level 8 to expand the delegation boundary by one step.
