Claude Code can invoke the same local aet CLI and consume the same JSON
contracts. Install the matching Skill folder when the host supports portable
Agent Skills, or load its SKILL.md as project instructions.
The shared boundary is the CLI and evidence files, not a vendor API. Command
execution requires an explicit /aet-proof request. A Bundle remains readable
without installing AET.
Compatibility claims are limited to the documented file and CLI contracts; host-specific UI behavior must be smoke-tested against the actual host version.
