The input to this skill is a spec bundle that the spec skill produced.

Before starting implementation, move to a new branch and worktree.

Implementation of the spec is carried out using the quest skill, which repeatedly invokes implementation agents until all work is complete. When prompting the agent, provide the full spec but only request that a single phase of the spec be implemented. This ensures that tasks given to agents are bounded in their effort.

Also request that the implementation agent marks tasks complete as they go.

If a phase comprises tasks that can be run in parallel, you may use multiple agents to build that phase.

When all phases have been implemented and all tasks have been marked as complete, up to [max-rounds] of adversarial review are carried out via a reviewer subagent.
