Level 2 Practice: Make a Bounded ProjectCard Edit
About 5 minutes
About This Tutorial
Section titled “About This Tutorial”For the concepts and completion standards, first read Codex Levels 0-10.
A small first edit makes it practical to review Codex output and detect unintended changes. This level limits work to the existing ProjectCard responsibility.
What You Will Complete
Section titled “What You Will Complete”You will produce a small reviewable diff. The goal is not the amount of work; it is a reproducible Level 2 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.
Add technology tags to ProjectCard using existing patterns. Limit changes to the component and directly related tests. Preserve routing, whole-card link behavior, and shared styles.Check: Continue only when Codex can restate the scope and unresolved questions before acting.
Step 2: Practice
Section titled “Step 2: Practice”- Limit the scope to
ProjectCardand directly related tests. - Add technology tags while preserving existing props, spacing, and link states.
- Review the diff for unrelated formatting or dependency changes.
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 git diff --stat matches the requested scope and existing card interactions remain intact.
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 3 to expand the delegation boundary by one step.
