Core approach

Encodes the AI-Driven Development Life Cycle as one harness-neutral core/ rendered into native distributions for several coding agents. A conductor selects or composes an appropriate scope, coordinates 14 specialist and review agents across 5 phases and up to 32 stages, persists every intent's artifacts and audit trail under aidlc/spaces/, and pauses at approval and phase-verification gates before downstream work proceeds.

Workflow

  1. Initialization — scaffold an intent record, detect greenfield or brownfield context, and initialize deterministic state and audit records
  2. Ideation — capture intent, assess feasibility, define scope, form the team, explore mockups, and approve the initiative
  3. Inception — reverse-engineer existing code when needed, discover team practices, analyze requirements, design the application, generate units, and plan delivery
  4. Construction — implement reviewable Bolt slices through functional, non-functional, and infrastructure design, code generation, build and test, and CI
  5. Operation — prepare and execute deployment, provision environments, establish observability and incident response, validate performance, and feed findings into the next intent
  6. Verification and control — run traceability checks between phases, approve material decisions, and resume, redo, or jump between persisted stages with /aidlc ($aidlc in Codex)

Supported tools

Strengths

  • Unusually complete lifecycle coverage, from initial intent through deployment, observability, incident response, and feedback
  • Nine stock scopes and three independent artifact-depth and test-strategy levels scale the 32-stage lifecycle from a bug fix or proof of concept to an enterprise initiative
  • Approval gates, phase-boundary traceability checks, persistent state, and a structured audit trail make decisions and resumptions explicit
  • One generated core/ keeps the methodology aligned across four supported products instead of maintaining separate prompt sets
  • Walking-skeleton and Bolt-based construction limits review size, with an explicit choice between gated and autonomous execution after the first slice

Limitations

  • Version 2 is developed on the protected v2 branch while the default main branch and GitHub Releases still foreground version 1; users must deliberately install and pin the intended version
  • The implementation is moving quickly despite its GA label, with substantial changes landing between tagged versions
  • All harness distributions require Bun; the bundled Claude Code and Codex configurations require Amazon Bedrock setup, while the recommended Kiro model requires a paid plan
  • Even with adaptive scopes, the full feature path has 32 stages and many approval gates, which is excessive for teams seeking a lightweight spec-to-code loop
  • The public evidence currently demonstrates a detailed implementation and early usage, not meaningful adoption or stable outcomes across multiple release cycles

Notes

AWS AI-DLC Workflows 2.0 is the executable implementation of AWS’s broader AI-Driven Development Life Cycle, not a new name for AI Unified Process. Its distinctive boundary is the whole delivery system: the version 2 documentation defines requirements and design artifacts, but also a deterministic state machine, specialist reviewers, construction slices, deployment stages, operational feedback, and durable team knowledge. The methodology is unusually explicit about its ceremony: a feature or enterprise scope includes all 32 stages, while smaller stock scopes and the adaptive composer remove stages only after showing the proposed plan for approval. That breadth and its fast-moving v2 implementation support an experimental rating rather than treating the project’s GA label as evidence of broad adoption or a settled methodology. This assessment observes the v2 branch at 6b26408.
