   +1 to supporting ty/ruff as well. The worst part about my opencode experience has been pyright causing crashes.

   Normally yes, but today, it was 99% CPU and never returning (on node 24). Appreciate you are not here to debug pyright hogging resources generally.

   Here's my opencode.json for ruff and mypy (using uv, if you use pip just remove uv run).
   You need python-lsp-server and pylsp-mypy packages intalled for mypy (and probably [tool.pylsp-mypy] enabled = true live_mode = true in pyproject.toml)

   {
     "$schema": "https://opencode.ai/config.json",
     "lsp": {
       "mypy": {
         "command": [
           "uv",
           "run",
           "pylsp",
         ],
         "extensions": [
           ".py",
           ".pyi"
         ]
       },
       "ruff": {
         "command": [
           "uv",
           "run",
           "ruff",
           "server",
         ],
         "extensions": [
           ".py",
           ".pyi"
         ]
       }
     }
   }
