subagent-driven-development
Use when executing implementation plans with independent tasks in the current session or facing 3+ independent issues that can be investigated without shared state or dependencies - dispatches fresh subagent for each task with code review between tasks, enabling fast iteration with quality gates
technical-review
Validate completed implementation against plan tasks and acceptance criteria. Sixth phase of research-discussion-specification-plan-implement-review workflow. Use when: (1) Implementation phase is complete, (2) User wants validation before merging/shipping, (3) Quality gate check needed after implementation. Reviews ALL plan tasks for implementation correctness, test adequacy, and code quality. Produces structured feedback (approve, request changes, or comments) - does NOT fix code.
technical-implementation
Execute implementation plans using strict TDD workflow with quality gates. Fifth phase of research-discussion-specification-plan-implement-review workflow. Use when: (1) Implementing a plan from docs/workflow/planning/{topic}.md, (2) User says 'implement', 'build', or 'code this' after planning, (3) Ad hoc coding that should follow TDD and quality standards, (4) Bug fixes or features benefiting from structured implementation. Writes tests first, implements to pass, commits frequently, stops for user approval between phases.
