speckit-implement

To execute a spec-kit implementation plan, run the tool at the repository root. It validates prerequisites, analyzes tasks.md and plan.md, and runs phase-by-phase work with dependency tracking and TDD-style checkpoints.

Task orchestration in spec-kit coordinates ordered execution using dependency and parallel markers in tasks.md. It tracks completion and stops automatically on non-parallel failures to maintain implementation correctness.

Spec-kit implementation supports custom extension hooks. It detects optional and mandatory before and after implementation hooks defined in .specify/extensions.yml and prepares them for execution at the correct phases.

To prevent skipping required work during TDD workflow implementation, the tool runs prerequisite scripts and verifies checklist completion status before executing any tasks, gating progress until all required validations pass.

You need .specify scripts, tasks.md, and plan.md in your repository for spec-kit implementation to work. Optionally, architecture-related docs can be loaded to provide additional context for phase-by-phase execution.

Spec-kit implementation stops on non-parallel task failures to maintain correctness. This deterministic coordination ensures that dependent tasks are not executed when prerequisite parallel tasks fail validation.
