Implement

This is a heavyweight orchestrator that spins up parallel subagents to build features across backend, frontend, testing, and security in one coordinated run. It handles full-stack implementations with worktree isolation, automatic tier classification from tier 1 (Interview Starter) to tier 6 (Open Source), and budget-aware phase scaling based on your effort setting. The thing that stands out is the resume capability: it writes state checkpoints so you can stop mid-implementation and pick up exactly where you left off. Designed for when you're building something substantial and want coordinated architecture, code generation, and test coverage without manually stitching together multiple agent sessions. Works best with the memory and context7 MCP servers loaded, though it will adapt if they're missing.
