Thanks for mentioning the openEHR-assistant MCP server - I went down probably to same trajectory as you did, It is the result of my own experiences and views combine d to formal specifications in informal guides available in the community. One thing that I stumble upon in your doc is the workflow image in page 2 is focusing too much on Templates, where as sometimes you need to model aspects that might not covered yet by the archetype sets. SO the process should also involve discovering, using or creating new archetypes .
