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.
