Spec-Driven Development

npx skills add addyosmani/agent-skills --skill spec-driven-development

A four-phase workflow — specify, plan, tasks, implement — where each phase waits for a human review before the next one opens. A scope check runs first and splits the request into a capability map when it bundles several independently testable features. The plan lands in tasks/plan.md and the task list in tasks/todo.md, so the reviewer reads a file instead of guessing at the agent's intent.
