From their changelog:

2.1.277

September 18, 2026

Added AGENTS.md support: in a project with no CLAUDE.md, Claude Code reads AGENTS.md instead; change it under “Project instructions” in /config (not yet on Bedrock, Vertex or Foundry)

Note that this *does not include .agents/skills*. Argh.

That would have been great. Coulda gotten rid of an entire symlink folder structure.
