Executing implementation plans
Executes a written plan in order, stopping at checkpoints to reconcile assumptions—useful for spec-driven builds and multi-step refactors.
Test-driven development
Uses red–green–refactor loops so behavior is pinned by tests first—ideal for new features, regressions, and refactors where you need a safety net.
OpenAI documentation lookup
Prioritizes official OpenAI docs, model cards, and API references when you need accurate integration guidance rather than stale blog summaries.
