GoKawiilAnthropic Publishes Six-Stage Playbook for Coding-Agent Software Development
Anthropic released a framework restructuring the software development lifecycle around AI coding agents, arguing that since agents made writing code fast, the bottleneck has shifted to planning, review, and verification. The playbook defines six stages—planning, design, build, deploy, and self-checking—each producing a document like intent.md, spec.md, or plan.md that feeds the next stage, with hooks preventing agents from gaming tests and CI evals treating agent configuration itself as software.
GoKawiil's interpretation of the reporting above, not reported fact.
The framework is notably detailed for an industry still improvising how to manage AI coding agents at scale, especially its idea of testing the agent's own instructions and hooks as rigorously as code. However, it assumes teams already have fast local tests and builds, leaving unresolved how agents should verify work against complex real-world systems with databases, queues, and external APIs—arguably the harder problem for most production software.
- Anthropic's playbook restructures the SDLC into six stages, each producing a machine-readable artifact for the next.
- Stage 4 focuses on self-verification, using hooks to stop agents from editing tests instead of fixing code.
- The framework treats agent configuration files as software requiring their own CI evals, but doesn't address verification against complex external dependencies.
Anthropic Claude Code (via Claude Pro subscription) — If you're rethinking your SDLC around coding agents, Martin Kleppmann's Designing Data-Intensive Applications is the reference that keeps your infrastructure thinking sharp — exactly the layer the article says the playbook glosses over. It's a durable, deeply practical guide to the systems your agents' code actually runs against, and a staple on engineering shelves.
