Codex Implement

Delegate code implementation to OpenAI Codex (gpt-5.4) via parallel subagents.

What It Does

Takes an approved plan and breaks it into independent implementation steps, each delegated to a Codex subagent running in parallel. Verifies changes, runs builds, and reports results.

Usage

/codex-implement

Reads the current plan from conversation context and delegates implementation. If no plan is in context, asks what to implement.

When to Use

• Multi-file implementation after plan approval
• Parallelizing independent code changes across files
• Delegating mechanical coding to Codex while Claude orchestrates

When NOT to Use

• Single-file changes (just implement directly)
• Exploratory work (Codex needs clear intent)
• Test-only changes (write tests where you can verify inline)
