* Scoping discussion - do research and figure out approach (auto mode)
* Planning - take the scoping and convert it to a concrete plan for review (plan mode)
* Implementation - put the plan into action (auto mode)
I find this works really well for my workflow, and it is really easy to trigger each phase because the model has clean boundaries. (This workflow is articulated in my user CLAUDE.md) Plan mode is still useful to me as it forces the model to double-check its plans (I find even with Opus 5.5 it still discovers gaps), and it gives me an opportunity to clear context at a really good spot.
So I would still consider plan mode to be useful. It would make me sad to see it go.
PS- I have a Claude Marketplace directory submission for an MCP server that has been sitting in review hell for six(!) months. I've never received any outcome other than "In Review". I hope I'm not asking too much but would it be possible to put me in touch with someone who might be able to help here. Nobody has ever replied to messages sent to mcp-review@anthropic or the "Anthony at Platform Operations" inquiring about status, and we are getting frustrated
