This MCP server has 11 tools with schemas and descriptions present, but quality is inconsistent. Most tool descriptions are adequate (50-150 chars), but several parameters lack descriptions or have vague ones. Schema completeness varies: some tools like `applyEdit` have detailed input schemas with multiple parameter options, while others like `npm` have minimal documentation. No output schemas are documented. Error handling is not evident in the tool definitions. The server targets a specialized domain (code validation, file editing, git operations) but lacks the polish expected for production use. Naming is generally clear (verb-noun pattern), but parameter naming has inconsistencies (e.g., `applyEdit` accepts `oldString`, `search`, `oldText` as alternatives, confusing for LLMs).

• Consolidate applyEdit parameters: use a single 'oldString' and 'newString' parameter. Remove 'search', 'replace', 'oldText', 'newText' aliases. Document the exact string-matching behavior (literal match? regex? case-sensitive?).
• Document output schemas for all tools. For example: gitStatus should return {branch: string, isDirty: boolean, stagedChanges: string[]}. This enables LLMs to chain tools correctly.
• Add error handling guidance to each tool description. Example for applyEdit: 'If oldString is not found, returns error with context: "String not found in file. Showing first 200 chars: [excerpt]". Agent should verify the string exists before calling.'
• Expand npm description to clarify: 'Installs npm packages into the current project. Modifies package.json and node_modules. Returns success/failure and list of installed versions. Retryable on network errors.'
• Add parameter constraints to lsp: clarify that line and character are 0-indexed, specify valid ranges, and document what each operation returns (e.g., diagnostics returns array of {line, character, message, severity}).
