SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Turn a written specification and acceptance criteria into an executable implementation plan and validated code, removing ambiguity and ad-hoc implementation decisions.

Core Features & Use Cases

  • Structured parsing: Extract goal, acceptance criteria, constraints, out-of-scope items, and ambiguities from a spec into a clear Parsed Spec section.
  • Mission planning: Produce a numbered mission list with file-level change maps, tests to write, dependency graphs, and parallelization opportunities.
  • Controlled execution & validation: Implement missions in dependency order, run targeted tests with a three-attempt Fix Mode, apply a circuit breaker for systemic failures, and run a final verification and guardrail checklist.
  • Use case: Ideal for engineering teams turning product specs into incremental, test-driven work that can be executed by one or multiple agents.

Quick Start

Run the spec-to-code skill on the spec file located at docs/plans/new-feature.md to parse acceptance criteria, produce missions, and propose a gated plan for execution.

FAQPage Schema
How do I turn a written specification into executable code?▼

To turn a written specification into executable code, parse the document's acceptance criteria into discrete missions, generate a dependency-ordered execution plan, and drive implementation through gated phases with iterative test validation.

What is spec-driven development and how does it handle mission planning?▼

Spec-driven development converts a feature spec into a structured mission list with file-level change maps, dependency graphs, and parallelization opportunities. This removes ad-hoc implementation decisions by enforcing a controlled, phased execution plan.

How do I automate test-driven development from a feature spec document?▼

Automating test-driven development from a spec involves running targeted tests during the execution phase, applying a three-attempt Fix Mode for failures, and triggering a circuit breaker for systemic issues to ensure code validation meets the original acceptance criteria.

Can I execute parallel coding missions generated from a single specification?▼

Yes, the parsed specification produces a numbered mission list that identifies parallelization opportunities and dependency graphs, allowing one or multiple agents to execute the generated coding missions in parallel where dependencies permit.

Does spec-to-code enforce guardrails like authorization and pagination during implementation?▼

Yes, during the final verification phase, the implementation undergoes a guardrail checklist that validates specific constraints including authorization, soft-delete, pagination, and UUID-only responses to ensure the code meets systemic requirements.

What are the limitations of automated spec parsing for complex codebases?▼

Automated spec parsing may struggle with unresolved ambiguities in the source document, and while a three-attempt Fix Mode handles test failures, a circuit breaker will halt execution if systemic failures indicate deeper architectural issues beyond the spec's scope.
