Use dynamic import instead of require.resolve() to detect @ast-grep/napi
installation. This fixes false negatives when running via bunx where the
module exists in ~/.config/opencode/node_modules but isn't resolvable
from the temporary execution directory.
Also adds fallback path checks for common installation locations.
Fixes#898
Implements a comprehensive 'doctor' command that diagnoses oh-my-opencode
installation health with a beautiful TUI output.
Checks performed:
- OpenCode installation (version, path, binary)
- Plugin registration in opencode.json
- Configuration file validity (oh-my-opencode.json)
- Auth providers (Anthropic, OpenAI, Google)
- Dependencies (ast-grep CLI/NAPI, comment-checker)
- LSP servers availability
- MCP servers (builtin and user)
- Version status and updates
Features:
- Beautiful TUI with symbols and colors
- --verbose flag for detailed output
- --json flag for machine-readable output
- --category flag for running specific checks
- Exit code 1 on failures for CI integration
Closes#333
