Spec Implement

Pick up tasks. Execute them. Track progress. Report. Stop when blocked.

This skill does not make design decisions or modify the plan. If the plan is wrong, go back to spec:plan. If the design is wrong, go back to spec:research.

Prerequisites

Before starting, verify these exist:

1. Approved spec — docs/specs/YYYY-MM-DD-<feature>/spec.md
2. Approved plan — docs/specs/YYYY-MM-DD-<feature>/plan.json
3. Tasks created — In beads or plan.json task list

If anything is missing, do not proceed. Tell the human what's needed.
