Loads a written implementation plan, reviews it critically, executes all tasks sequentially, and reports when complete — without improvising beyond the plan's scope.

Guides completion of development work by verifying tests first, then presenting structured options for merge, PR creation, or cleanup — never declaring done without a passing build.

Finds the root cause before attempting any fix — building a minimal reproduction, forming ranked hypotheses, and instrumenting to confirm before writing a single corrective line.

Explores user intent, requirements, and design before implementation. Turns ideas into fully formed designs and specs through natural collaborative dialogue.

Executes plans by dispatching a fresh subagent per task with a two-stage review (spec compliance then code quality), keeping the orchestrator context clean throughout.

Writes comprehensive implementation plans that break multi-step tasks into bite-sized, independently executable sub-tasks before any code is touched.

Requires running verification commands and confirming their output before claiming any work is complete, fixed, or passing — no claim without evidence.

Delegates independent tasks to specialized agents with isolated context to work concurrently, dramatically reducing wall-clock time on multi-part problems.

Processes code review feedback with technical rigor and verification before implementation — questioning unclear feedback and confirming fixes with tests rather than blindly applying suggestions.

Dispatches a code reviewer subagent with isolated context to catch issues before they cascade — producing a structured review report that guides targeted fixes.

A complete software development methodology for coding agents — brainstorming, planning, parallel execution, systematic debugging, code review loops, and branch discipline unified into a single agentic workflow.

Ensures every piece of feature work begins in an isolated workspace — creating a native git worktree when available, falling back to tool-provided isolation otherwise.
