The tools have overlapping purposes that could cause confusion. getDiagnosticsForFile and getDiagnosticsForPath both retrieve diagnostics for a single file, with the latter described as more flexible and recommended, creating ambiguity about when to use each. However, getDiagnostics and getDiagnosticsSummary serve clearly distinct purposes (all files vs. summary statistics), which helps mitigate some confusion.

All tool names follow a consistent camelCase pattern with a clear verb_noun structure (getDiagnostics, getDiagnosticsForFile, getDiagnosticsForPath, getDiagnosticsSummary). The naming is predictable and readable throughout the set, with no deviations in style or convention.

With 4 tools, the count is well-scoped for a diagnostics server. Each tool appears to serve a specific and necessary function (e.g., retrieving all diagnostics, per-file diagnostics, and summaries), making the set focused and manageable without being overly sparse or bloated.

The tool surface covers core diagnostics retrieval operations comprehensively, including all files, per-file, and summary views. A minor gap exists in the lack of tools for managing or clearing diagnostics (e.g., reset or update functions), but agents can likely work with the provided read-only operations for most use cases.
