Claude Code's AGENTS.md support requires telemetry to be enabled
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.
