Automated daily validation of Go and TypeScript/JavaScript language server functionality via Serena MCP server (ghcr.io/github/serena-mcp-server:latest). Creates tracked issues on failure.

Implementation

  • .github/agentics/language-support-tester.md: Agent prompt testing activate_project, symbol resolution, and language server responses for both languages
  • .github/workflows/language-support-tester.md: Workflow config with daily fuzzy schedule, safe-outputs for issue creation, 7d issue expiration
  • .github/workflows/language-support-tester.lock.yml: Compiled GitHub Actions workflow

Technical details

  • Uses serena: ["go", "typescript"] (TypeScript identifier covers JavaScript files)
  • Tests Go against /workspace/internal/ and TypeScript against /workspace/test/serena-mcp-tests/samples/js_project/
  • Strict mode compliant: read-only permissions with safe-outputs for write operations
  • Runtime-import pattern enables prompt iteration without recompilation
  • Issues tagged language-support, serena-mcp, automation with [language-support] prefix

Example workflow structure

tools:
  serena: ["go", "typescript"]
  github:
    toolsets: [default]
safe-outputs:
  create-issue:
    title-prefix: "[language-support] "
    labels: [language-support, serena-mcp, automation]
    expires: 7d

The safe-outputs configuration specifies that the create-issue tool will automatically add labels [language-support serena-mcp automation], but line 44 in the agent prompt instructs the agent to manually tag issues with labels language-support and serena-mcp. This is redundant since these labels are automatically added by the safe-outputs configuration. The instruction should be updated to clarify that these labels will be added automatically, or the agent should only be instructed to add any additional labels beyond those three if needed.

Suggested change
- Tag with label: `language-support` and `serena-mcp`
- Note: the `create-issue` safe output will automatically add the `language-support`, `serena-mcp`, and `automation` labels; add any additional labels only if needed
