Four read-only tools with complete input schemas and descriptions. Naming follows verb_noun convention (list_, read_, search_, get_). Descriptions are adequate (100-150 chars) but lack LLM-optimized guidance on when to use each tool vs. alternatives. Parameters are typed and described, but lack constraints (enums, ranges, patterns). Output schemas are not documented in the source code provided. Error handling and recovery guidance are absent. No tool annotations (readOnlyHint, etc.) despite all being read-only operations.

• Document output schemas for all four tools. Example for list_files: {type: 'object', properties: {files: {type: 'array', items: {type: 'object', properties: {path: string, type: 'file'|'directory', size: number}}}, total_count: number}}
• Add readOnlyHint: true to all tool definitions to signal to agents that these operations are safe and idempotent.
• Add numeric constraints to parameters: max_depth (1-100), max_bytes (1-10485760), max_results (1-1000), context_lines (0-50). Include these in parameter descriptions.
• Enhance descriptions with decision guidance: 'Use list_files to discover structure; use search_files to find content matching a pattern. Call get_repo_overview first to understand the codebase layout.'
• Add error handling examples in descriptions: 'If file exceeds max_bytes, the tool returns a truncation notice. For encoding errors, try base64 encoding. For invalid patterns, the tool returns a validation error with the offending pattern.'

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
