SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converts validated design specs into concrete, phased implementation plans that teams can execute with clear tasks and checkpoints.

Core Features & Use Cases

  • Automated task mapping: transforms design sections into a phased task breakdown with ownership and milestones.
  • Review gates: prints security and quality checkpoints aligned with the design spec risks.
  • Output artifact: generates planspec/implementations/[topic].md ready for execution and auditing.

Quick Start

Run planspec:impl-spec planspec/designs/[topic].md to generate planspec/implementations/[topic].md

FAQPage Schema
How do I convert a validated design spec into a phased implementation plan?

To convert a validated design spec into a phased implementation plan, run the tool against your design markdown file to automatically map design components into actionable tasks, checkpoints, and security gates.

What is the best way to generate actionable tasks from a design spec?

The best way to generate actionable tasks from a design spec is using an automated task mapper that enforces must-have design sections, details dependencies, and outputs a structured markdown file with phased task breakdowns and milestones.

How does mapping design components to phased tasks with checkpoints work?

Mapping design components to phased tasks works by analyzing the validated design spec, extracting required sections, detailing prerequisites, and structuring the output with aligned security and quality review gates for team execution.

Can I enforce security review checkpoints when creating an implementation plan?

Yes, you can enforce security review checkpoints when creating an implementation plan. The process automatically prints security and quality checkpoints aligned with the specific risks identified in the original design spec.

Do I need a completed design spec to generate a phased task breakdown?

Yes, you need a completed design spec to generate a phased task breakdown. The process applies after brainstorming is complete, enforcing must-have sections from the spec to map design components to actionable implementation tasks.

What limitations exist when generating implementation plans from design specs?

A key limitation when generating implementation plans is that the design spec must be fully validated and written beforehand. The tool maps existing design components to tasks rather than generating the initial design itself.
