Starting with 2.1.277, Claude Code claims support for AGENTS.md — "in a project with no CLAUDE.md, Claude Code reads AGENTS.md instead." But the feature is implemented as a built-in plugin that is off by default and gated behind a remote Anthropic feature flag (Statsig gate tengu_agents_md_mod). If you disable telemetry traffic (CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1), or use Claude Code through a third-party gateway / Bedrock / Vertex, that gate can never evaluate to true — and so reading a local markdown file, an act that requires no network whatsoever, is silently locked away by a server-side switch. No error. No warning. It just doesn't load.
