A developer testing Claude Code 2.1.277's new AGENTS.md support found the file only loads when a remote feature flag called tengu_agents_md_mod returns true, which depends on telemetry or nonessential traffic being enabled. Setting CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC or DISABLE_TELEMETRY to 1 silently disables the AGENTS.md loader, with no warning to the user, a behavior tracked in GitHub issue #95690.
Anthropic's Claude Code tool will now read an AGENTS.md file when a project lacks a CLAUDE.md file. This lets developers who already use the AGENTS.md convention for agent instructions get compatible behavior from Claude Code without creating a duplicate configuration file.
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.
