Implementation plan execution validates prerequisites, coordinates phase-by-phase tasks, and enforces dependency rules across your repository. It reads tasks.md and plan.md to guide the execution flow and verify completion.

Checklist completion enforcement scans your feature directory's checklists to compute PASS/FAIL status, optionally blocks execution when incomplete, and prompts the user to continue, ensuring validation steps are met before proceeding.

A .specify directory is required containing tasks.md and plan.md as execution sources. Optional context files like data-model.md, contracts/, research.md, and quickstart.md can be loaded to provide additional implementation context.

Extension hooks run pre-implement and after-implement configurations from .specify/extensions.yml, respecting optional versus mandatory behavior and silently skipping invalid hook configurations to maintain smooth execution flow.

Project setup verification detects characteristics like git, Docker, JS/TS/ESLint/Prettier, Terraform, and Helm, ensuring ignore files exist and contain essential patterns before task execution begins in your repository.

Task execution follows dependency and parallel rules defined in your plan. If prerequisites are unmet or checklist gates block execution, tasks run sequentially or pause until validation requirements are satisfied.
