description	Проверка LSP и Serena prerequisites для Python/Rust/Dart/Flutter/TS/JS/Go/C++/Qt/YAML/Docker/HTML/CSS/Shell. Используй для: проверь LSP, проверь язык-серверы, диагностики LSP, доступны ли LSP в проекте. EN triggers: check LSP, language server health, LSP diagnostics, verify LSP setup, are LSP installed, LSP project prerequisites, LSP doctor.

LSP Health Check

Purpose

Verify that language servers and project prerequisites are available before relying on diagnostics, semantic navigation, or Serena symbol tools.

Workflow

1. Check OpenCode LSP configuration: verify opencode.json has "lsp": true or appropriate per-server configuration for the project languages.
2. Detect project languages from manifests, build files, lockfiles, and source files.
3. Verify that relevant LSP servers auto-start for detected file extensions.
4. Report missing language support separately from project prerequisite warnings.
5. For C, C++, and Qt C++, treat missing compile_commands.json as a serious warning because diagnostics may be wrong.
6. For TypeScript and JavaScript, verify tsconfig.json or jsconfig.json.
7. For Python, verify pyproject.toml, pyrightconfig.json, or virtual environment expectations.
8. For Dart and Flutter, verify pubspec.yaml, analysis_options.yaml, and dependency resolution.
9. Do not start raw stdio LSP sessions as a test - they hang waiting for a real LSP client.

Default LSP Availability

OpenCode has 30+ built-in LSP servers that auto-start when file extensions are detected. These include:

• Pyright (Python), typescript-language-server (TS/JS), rust-analyzer (Rust), dart analysis server (Dart/Flutter), gopls (Go), clangd (C/C++), and many more.

If "lsp": true is set in opencode.json, these auto-start. If specific configuration is needed, use the lsp object in opencode.json for per-server overrides.

Output

In Russian, summarize:

• Available and missing LSP support.
• Project prerequisite warnings.
• What must be installed or configured next.
• Whether Serena semantic work is safe for the detected languages.
• OpenCode LSP configuration status.

Anti-patterns

• Running pyright-langserver --stdio without an LSP client (hangs).
• Ignoring project prerequisite warnings (compile_commands.json for C/C++ is critical).
• Claiming "LSPs work" without verification through OpenCode configuration or command -v.
• Reinstalling already working executables only for package manager standardization.
