Day Shift with Codex or Claude Code: what belongs in the repository

Use coding assistants for implementation; keep the durable implementation contract and evidence in versioned repository files.

Direct answer

Codex or Claude Code can explore, implement, and explain changes. The repository should retain the durable agreement: specification, task scope, target paths, validation, implementation summary, and reconciliation. That makes the workflow portable across agents and reviewers.

Practical guidance

Make the next review decision easier.

Keep prompts temporary

Prompts and tool-specific context help an agent work in the moment, but they are not a reliable repository record. Preserve the decisions and evidence that another contributor must be able to audit.

Keep contracts versioned

Task definitions make the allowed change boundary and validation visible in code review. They can be read by any coding agent without requiring the original tool, model, or conversation.

Keep judgment explicit

A human still resolves ambiguous product intent, risk, and conflicting evidence. The workflow makes that judgment traceable instead of treating model output as approval.

Verified demo evidence

A public CLI result, not a completion claim.

This command and result are from the website’s checked-in synthetic repository demo. Substitute your own repository paths and validation command when you apply the workflow.
