Determinism over Vibes

What is ASDLC?

Agentic Software Development Life Cycle (ASDLC) is a structured approach to building software in collaboration with Large Language Models (LLMs), autonomous agents, and AI-powered development tools.

This knowledge base documents the concepts, patterns, and practices that enable deterministic, repeatable outcomes when working with non-deterministic AI systems.

The Manifesto

In the era of AI-assisted development, we reject "vibe coding" — the practice of accepting whatever output an LLM produces without validation, types, or tests.

Instead, we advocate for:

• Schema-First Development: Define your data contracts before generating content.
• Type Safety: No any, no guessing, no hallucinated imports.
• Strict Linting: Enforce code quality at commit-time, not PR-time.
• Conventional Commits: Machine-readable history for automated workflows.
• Agent Directives: Explicit protocols that govern AI behavior in your codebase.

When AI contributors follow explicit rules defined in AGENTS.md, when schemas validate data at build-time, and when tests prevent regressions — that's when determinism emerges from the vibes.

How to Use This Knowledge Base

This site is organized into two primary collections:

• Concepts: Definitions, taxonomies, and theoretical foundations for ASDLC practices. Each concept includes maturity level, tags, and relationships to other concepts.
• Patterns: Proven solutions to recurring problems in agent-driven development. Each pattern includes complexity ratings, implementation guidance, and optional diagrams.

All content is versioned, validated against Zod schemas, and maintained with the same rigor as production code.
