+-------------------+----------------------------------+----------------------------------+----------------------------------+
Claude AGENTS.md workaround: Claude Code does not read AGENTS.md natively
(see https://code.claude.com/docs/en/memory). ynh exports a CLAUDE.md containing
just @AGENTS.md which uses Claude's @-import syntax to pull in the cross-vendor
instructions file. This avoids duplicating content while ensuring Claude reads the
instructions. The plugin's CLAUDE.md lives inside the plugin directory, so it does
not conflict with the project's own CLAUDE.md.
