A team evaluates Copilot cloud agent over 30 issue-assignment runs. The agent usually creates a draft pull request, but review feedback shows repeated violations in generated API changes. Which change should you make first? Select one answer.

The repeated violations in API changes, specifically modifying generated OpenAPI client files directly, skipping pnpm test:contracts, and changing src/api/routes/ without updating tests/contracts/, strongly indicate a lack of understanding or adherence to contract testing and API design principles by the Copilot agent. Adding explicit contract instructions to .github/copilot-instructions.md and integrating contract test checks into the validation workflow will directly address these recurring issues by guiding the agent and enforcing proper behavior. Increasing the model context size might not solve the problem if the agent isn't explicitly instructed on contract best practices. Converting draft pull requests to ready is premature and risky given the quality issues. Adding a schedule for nightly validation is a reactive measure and won't prevent the agent from making the same mistakes in the first place.
