SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converts a defined FIS into a working implementation by executing or implementing the spec with disciplined verification, ensuring traceability to the FIS tasks and outcomes.

Core Features & Use Cases

Execute a fully specified FIS end-to-end, driving implementation with Step-based gates and per-task verification.
Coordinate advisory sub-agents and skills for documentation, architecture, and testing while maintaining FIS as the single source of truth.
Update the FIS with progress, observations, and discovered requirements as you complete tasks.

Quick Start

Provide the path to a FIS file and let the executor run the entire spec from start to finish.

FAQPage Schema

How do I execute a feature implementation specification end-to-end?▼

To execute a feature implementation specification end-to-end, provide the path to your spec file and the executor will run the entire specification from start to finish, driving implementation with step-based gates and per-task verification.

What is a Feature Implementation Specification (FIS) used for?▼

A Feature Implementation Specification (FIS) serves as the authoritative contract and single source of truth for implementation, ensuring disciplined verification and traceability from defined tasks to working software outcomes.

How do I automate test scaffolding when implementing a specification?▼

You can automate test scaffolding during implementation by having the executor read specification provenance and automatically scaffold required tests when needed to enforce governance gates.

Can I coordinate advisory sub-agents while executing a specification?▼

Yes, you can coordinate advisory sub-agents and skills for documentation, architecture, and testing during execution while maintaining the specification as the single source of truth.

What is the best way to maintain traceability when implementing a spec?▼

The best way to maintain traceability is to use the specification as an authoritative contract, updating it directly with progress, observations, and discovered requirements as you complete tasks.
