SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning a written task breakdown into working code requires careful sequencing, dependency tracking, and progress bookkeeping; this Skill automates that execution loop so tasks.md becomes a completed, validated implementation. ## Core Features & Use Cases - Phased Task Execution: Parses tasks.md into phases (Setup, Tests, Core, Integration, Polish), respects sequential dependencies, and runs parallel [P] tasks together. - Checklist Gating: Scans checklists in the feature directory, reports pass/fail status, and asks before proceeding when items are unchecked. - Project Setup Verification: Detects the tech stack from plan.md and creates or verifies ignore files (.gitignore, .dockerignore, .eslintignore, and more). - Extension Hooks: Runs optional and mandatory before/after implementation hooks declared in .specify/extensions.yml. - Use Case: After generating a task list with /speckit-tasks, invoke this Skill to implement the feature end to end, marking each completed task [X] and halting with clear errors if a non-parallel task fails. ## Quick Start Run the speckit-implement skill to execute all tasks in tasks.md for the current feature.

FAQPage Schema
How do I execute a tasks.md implementation plan with spec-kit?▼

Invoke the speckit-implement skill after generating tasks.md. It runs check-prerequisites.sh, loads plan.md and tasks.md, then executes tasks phase by phase, respecting dependencies and parallel [P] markers while marking completed tasks [X].

What happens if checklists have unchecked items before implementation?▼

The skill scans all files in the checklists/ directory, builds a status table of total, checked, and unchecked items, then stops and asks whether to proceed. Implementation only continues after explicit user confirmation.

Does speckit-implement require a specific project structure?▼

Yes, it requires a spec-kit project with a .specify/ directory containing scripts like check-prerequisites.sh, plus a feature directory holding tasks.md and plan.md. If tasks are missing, it suggests running /speckit-tasks first.

How are parallel and sequential tasks handled during implementation?▼

Tasks marked [P] can run in parallel, while tasks touching the same files run sequentially. If a non-parallel task fails, execution halts; for parallel tasks, successful ones continue and failures are reported.

What are extension hooks in spec-kit implementation?▼

Hooks are commands declared under hooks.before_implement or hooks.after_implement in .specify/extensions.yml. Mandatory hooks (optional: false) are executed automatically, while optional hooks are presented for the user to run manually.
