Single tool with clear naming and adequate schema. Tool name 'dump_codebase_context' is action-verb-based and descriptive. Input schema is fully specified with types, descriptions, and constraints (minimum values, defaults). However, output schema is entirely undocumented, the handler returns a ToolHandlerReturnType but no output structure is described to the LLM. Parameter descriptions are present but somewhat terse. Error handling is basic (generic McpError for unknown tool and invalid params, but no actionable recovery guidance or error categorization). No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite this being a READ_ONLY operation. The tool is well-defined for input but fails to guide LLM reasoning about output structure and error recovery.

• Document the output schema in code comments or a schema object. Example: '{ "type": "object", "properties": { "content": { "type": "string", "description": "Concatenated file contents with headers/footers" }, "files_processed": { "type": "integer" }, "files_skipped": { "type": "integer" } } }'
• Add readOnlyHint annotation to the tool definition to signal that the tool is safe to retry and has no side effects.
• Enhance error handling: (1) when base_path does not exist, return 'Path not found: /path/to/dir. Verify the path is absolute and accessible.' instead of generic InvalidParams. (2) When a file read fails, return per-file errors in a 'files_with_errors' array instead of failing the entire operation.
• Expand parameter descriptions: 'num_chunks: Divide the output into this many chunks to handle large codebases. If num_chunks=3, output is split into 3 roughly equal parts. Useful for LLMs with context windows smaller than the full dump. Requires chunk_index to also be set.'
• Add constraints to the tool description: 'Returns up to 100 MB of text content. Larger codebases require chunking (num_chunks > 1). Typical latency: 1-10s for codebases <10k files. Respects .gitignore rules and skips binary files.'
• Consider adding a max_depth parameter to limit recursion depth, and document it: 'Maximum nesting depth to scan (default: unlimited). Useful to exclude deeply nested node_modules or vendor directories without .gitignore entries.'
