SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill turns a spec-kit implementation workspace into a guided, step-by-step execution flow that validates prerequisites, enforces checklist completion, and then runs the tasks defined by the project plan.

Core Features & Use Cases

  • Preflight readiness checks: Verifies prerequisites using repo scripts and derives FEATURE_DIR and AVAILABLE_DOCS from project structure.
  • Checklist pass/fail gating: Scans checklists to compute an overall PASS/FAIL and prompts the user if anything is incomplete.
  • Plan-driven orchestration: Loads tasks.md and plan.md (plus optional context files) to execute phases in order while respecting dependencies and parallel [P] markers.
  • Extension hook support: Runs optional/mandatory before_implement hooks (and after_implement hooks post-validation) based on .specify/extensions.yml.
  • Project hygiene verification: Ensures ignore/config files exist and are consistent with detected tooling in the plan.

Quick Start

Run speckit-implement from the repo root of your spec-kit project to execute the implementation tasks defined in tasks.md after passing prerequisite and checklist validations.

Frequently Asked Questions about speckit-implement

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

FAQPage Schema
How do I execute tasks from a spec-kit tasks.md file safely?▼

To execute tasks from a spec-kit tasks.md file safely, you need an orchestration workflow that validates prerequisites, enforces checklist completion, and respects sequential dependencies before running phased development or parallel task markers.

How does checklist validation gate the TDD workflow implementation process?▼

Checklist validation gates the TDD workflow by scanning checklists to compute an overall PASS or FAIL status, prompting the user to resolve incomplete items before allowing any task execution from the plan to proceed.

Can I run parallel tasks marked with [P] during spec-kit implementation?▼

Yes, you can run parallel tasks marked with [P] during spec-kit implementation, provided the orchestration workflow has verified sequential dependencies and passed prerequisite checks for those specific phased development items.

Does implementation orchestration support custom extension hooks in .specify/extensions.yml?▼

Implementation orchestration supports custom extension hooks in .specify/extensions.yml by running optional or mandatory before_implement hooks prior to task execution and after_implement hooks post-validation to integrate external tooling.

What prerequisites are required before executing a plan.md implementation workflow?▼

Before executing a plan.md implementation workflow, prerequisites include verifying project hygiene, deriving FEATURE_DIR and AVAILABLE_DOCS from the project structure, and ensuring ignore and config files are consistent with detected tooling.
