Verified Spec-Driven Development (VSDD)

4 hours ago

Verified Spec-Driven Development (VSDD) combines Spec-Driven Development (SDD), Test-Driven Development (TDD), and Verification-Driven Development (VDD) into a unified AI-orchestrated pipeline.
VSDD follows a structured process: Spec Definition → Test Generation → Implementation → Adversarial Verification → Formal Verification → Convergence.
Key roles include the Architect (human developer), Builder (AI for specs, tests, and code), Tracker (Chainlink for issue decomposition), and Adversary (hyper-critical AI reviewer).
Specs define behavioral contracts, verification architecture, and non-functional requirements before any implementation begins.
Tests are generated from specs and must fail before implementation (Red → Green → Refactor).
Adversarial verification ensures fidelity to specs, test quality, and code robustness, with fresh context resets for unbiased reviews.
Formal verification tools (e.g., Kani, CBMC, Dafny) validate provable properties, leveraging purity boundaries for deterministic core logic.
Convergence is achieved when specs, tests, implementation, and proofs survive adversarial scrutiny without meaningful gaps.
VSDD emphasizes traceability, anti-slop bias, and AI model diversity (Builder vs. Adversary) for high-quality outputs.
Best suited for high-stakes domains (finance, healthcare, security) where correctness and maintainability are critical.
