SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Projects and features often suffer from vague requirements, scope creep, and disconnected implementation steps; this skill provides a structured, traceable workflow that turns goals into testable specifications and atomic tasks, reducing ambiguity and rework.

Core Features & Use Cases

  • Four-phase workflow: Specify, Design, Tasks, Implement+Validate to move from idea to verifiable implementation.
  • Persistent project memory: Creates and maintains .specs artifacts (PROJECT.md, ROADMAP.md, STATE.md) for session continuity, decisions, and blockers.
  • Brownfield and greenfield support: Map existing codebases into STACK/ARCHITECTURE/CONVENTIONS/STRUCTURE/TESTING/INTEGRATIONS artifacts, then plan and execute feature work with clear dependencies and acceptance criteria.
  • Context and model guidance: Manages context loading limits, suggests appropriate model classes for tasks, and enforces WHEN/THEN acceptance criteria for verification.

Quick Start

Say Initialize project to create PROJECT.md and set up the .specs directory so the agent can begin spec-driven planning.

Frequently Asked Questions about tlc-spec-driven

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

FAQPage Schema
How do I break down a software project into testable specifications and atomic tasks?▼

To break down a software project into testable specifications, use a spec-driven workflow that moves through Specify, Design, Tasks, and Implement+Validate phases, generating artifacts like spec.md and tasks.md to reduce ambiguity and rework.

What is the best way to map an existing brownfield codebase before planning new features?▼

Mapping an existing brownfield codebase involves generating persistent .specs artifacts that document STACK, ARCHITECTURE, CONVENTIONS, STRUCTURE, TESTING, and INTEGRATIONS to provide traceable context for new feature planning.

How do I maintain session continuity for project planning across multiple agent interactions?▼

Maintain session continuity by creating and maintaining persistent project memory artifacts like PROJECT.md, ROADMAP.md, and STATE.md within a .specs directory to track decisions, state, and blockers across interactions.

How do you enforce acceptance criteria for feature implementation and validation?▼

To enforce acceptance criteria for feature implementation, define strict WHEN/THEN conditions within your specification artifacts, ensuring that implementation and validation phases verify against these testable requirements.

Can spec-driven planning manage context loading limits for large codebases?▼

Spec-driven planning manages context loading limits for large codebases by respecting context boundaries and suggesting appropriate model classes for specific tasks, ensuring the agent operates efficiently within its processing constraints.
