+## TODO

+- Communicate through the MCP server's up-front prompts which tool parameters
+  are _generally_ mutually exclusive with each other unless the user indicates
+  or hints otherwise.
+  - Maybe make it user-configurable?
+- _Optionally_ include a tool that calls a configurable LLM for task time
+  estimations so the main LLM doesn't have to guess.
