SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a written specification and task breakdown into working code is error-prone: tasks get skipped, dependencies are ignored, and checklists go unverified. This Skill automates the execution phase of a spec-driven workflow by reading tasks.md and plan.md, then implementing every task in the correct order with progress tracking. ## Core Features & Use Cases - Checklist gating: Scans all checklist files in the feature directory, reports completion status in a table, and asks for confirmation before proceeding when items are incomplete. - Phase-based execution: Parses task phases (Setup, Tests, Core, Integration, Polish), respects sequential vs parallel [P] dependencies, and follows a tests-before-code TDD approach. - Project setup verification: Detects the tech stack and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, etc.) with technology-appropriate patterns. - Use Case: After running /speckit.tasks to generate a task breakdown for a new feature, invoke this Skill to implement all tasks end-to-end, marking each completed task as [X] in tasks.md and validating the result against the original specification. ## Quick Start Run the speckit.implement skill to execute all tasks in tasks.md for the current feature and mark each completed task as done.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I execute a tasks.md implementation plan automatically?▼

Run this Skill after generating tasks.md with /speckit.tasks. It reads the task list, plan.md, and optional artifacts like data-model.md and contracts/, then implements each phase in dependency order while marking completed tasks as [X].

What happens if checklists are incomplete before implementation?▼

The Skill scans all checklist files, displays a status table with complete and incomplete counts, and stops to ask whether you want to proceed anyway. It only continues after explicit confirmation such as yes, proceed, or continue.

Does it support parallel task execution?▼

Yes. Tasks marked with [P] in tasks.md can run in parallel, while sequential tasks run in order. Tasks affecting the same files are coordinated to run sequentially, and failed parallel tasks are reported without halting successful ones.

Which ignore files does it create during project setup?▼

It detects the project setup and creates or verifies .gitignore, .dockerignore, .eslintignore, .prettierignore, .npmignore, .terraformignore, and .helmignore as applicable, using pattern sets matched to the tech stack found in plan.md.

What should I do if tasks.md is missing or incomplete?▼

The Skill assumes a complete task breakdown exists. If tasks are missing or incomplete, run /speckit.tasks first to regenerate the task list, then invoke the implementation step again.
