AI-assisted development at enterprise scale requires more than good prompts. It requires a methodology — a repeatable system that produces consistent quality regardless of which engineer is working on which module. This is ours.
Spec-as-evidence, not spec-as-handcuff
Specifications and code mature together rather than one waiting on the other. Generation is fast and exploratory — we iterate with you in the room, throw work away, regenerate, and let the right answer emerge from working evidence. When a piece is ready, the spec captures what it does and why, gets signed off, and rides into production alongside the code as audit evidence. The point is not to write the spec before any code exists; the point is that nothing reaches production without one.
The DECON Quality Gate
A 28-stage Argus runs by default on every change. Eight stages anchor every gate run: Spec → Critique Review (a different model from the generator) → Architect Review (cryptographically signed sign-off bound to the commit) → SAST → SCA → DAST → Tests → Docs. Twenty additional stages compose around them based on what the engagement is building — accessibility, performance, AI-output quality, license, API contract, data quality, observability, and others. Stages skip only when they don't apply, when client-side infrastructure they need is absent (with a warning rather than a silent pass), or when their compute cost is high enough to run on a scheduled cadence rather than per-merge. The gate is automated in CI/CD, not a checklist a developer runs manually.
Architecture Conformance Checking
We sketch bounded contexts and domain boundaries early in the engagement and refine them as the build clarifies. Automated conformance checks on every merge verify that code stays within those boundaries as the system grows. This prevents the slow drift where a well-designed system becomes a ball of mud over eighteen months. The architecture you signed off on in the first weeks is the architecture that ships.
The Prompt Library and Review System
We maintain a versioned, tested library of prompt templates that accumulates across engagements. Templates are reviewed, benchmarked against held-out evals, and approved before they enter the library. Engineers do not prompt from scratch; they start from validated foundations and the library grows with every engagement.
Migration Toolkit
Reusable patterns for replacing SaaS or on-prem systems without downtime: incremental cutover, Anti-Corruption Layer with explicit retirement dates, Change Data Capture in both directions, phased-rollout playbooks, one-command rollback at every step. The patterns are typed and the cutover-ready check is a CLI gate, not a checklist. Adapted and extended for every client's specific data model.
