AI BriefingAnthropic Releases AI-Native SDLC
Key point
Anthropic has formalized agent-based development workflows, signaling a shift in the code review paradigm.
Details
Anthropic has released an AI-native SDLC (Software Development Life Cycle) playbook. This approach consists of six stages: planning, design, build, test, deploy, and maintain, with deliverables for each stage fixed as committed Markdown files such as intent.md, spec.md, and plan.md.
Key Change: Shift in Review Method
In an environment where agents generate most code diffs, manual line-by-line reviews are inefficient. Instead, the structure shifts to agents generating and verifying, while humans approve at gates. Specific hooks can block tasks without the signature of designated individuals.
Bottleneck Shift Seen in Data
According to Faros AI telemetry (10,000 developers, 1,255 teams), teams with high AI adoption rates have 98% higher PR merge rates, 91% increased review times, and 154% larger average PR sizes. The DORA 2025 report also notes that while throughput has increased, stability has decreased. This indicates that the bottleneck has shifted from writing code to 'deciding what to write' and 'verifying results'.
Convergence of the Open Source Ecosystem
Open source tools such as GitHub's Spec Kit (MIT license) and AGENTS.md, which exists in over 60,000 repositories, are forming the same loop. The playbook is already being packaged and distributed as skills for Claude Code and Codex.
