FAQPage Schema
How do I create and optimize Codex skills efficiently?

To create and optimize Codex skills, you follow a structured process of defining skill behavior, running evaluations, and iterating based on feedback. This involves analyzing test results and revising the skill to improve performance.

What is the best way to measure AI skill performance?

Measuring AI skill performance involves benchmarking the skill using quantitative metrics and qualitative feedback. You run evaluations and tests to assess improvements, ensuring the skill meets the desired functionality and handles edge cases effectively.

How do I iterate on an existing AI development skill?

Iterating on an AI development skill requires analyzing user feedback and performance benchmarks, revising the skill's logic, and running subsequent tests. This cycle of evaluation and improvement refines the skill's behavior over time.

What do I need to define when building a new skill from scratch?

When building a new skill, you need to provide user input for defining the skill's functionality, specifying its core behavior, and handling potential edge cases. This initial definition guides the entire development and evaluation process.

Can I improve an existing Codex skill without starting over?

Yes, you can improve existing Codex skills by refining them based on current performance metrics and user feedback. This involves targeted revisions and running tests to assess specific improvements rather than rebuilding from scratch.

Why should I run evaluations during skill development?

Running evaluations during skill development is necessary to measure performance quantitatively and qualitatively. It highlights areas needing improvement, validates that edge cases are handled, and ensures the skill behaves as intended before deployment.
