Multi Phase Plan Execution With Chat Tell Build Apply Lifecycle

via “cross-model development workflow with plan mode and phase-gated execution”

from vibe coding to agentic engineering - practice makes claude perfect

Unique: Implements a two-stage workflow (planning with Plan agent, execution with specialized agents) with phase-gated progression that validates each phase before proceeding. This separates planning concerns from execution concerns and enables model selection optimization (cheaper models for execution, more capable models for planning).

vs others: More structured than single-model execution because it enforces planning before execution; more cost-effective than using a single powerful model for all tasks because it uses cheaper models for execution after expensive planning.
