Critical gaps across all dimensions. Tool definitions lack proper schemas, most parameters are inferred from code rather than explicitly registered. Descriptions are present but generic (avg ~60 chars, well below 194-char baseline). No input validation, error handling guidance, or output schema documentation. Tools like 'shell' and 'Bash' are duplicates with identical risk profiles. Parameter descriptions are minimal or absent. No evidence of idempotency, permission gates, or secret injection patterns. This server exposes dangerous operations (shell execution, file writes) with minimal safeguards.

• Merge 'shell' and 'Bash' into a single 'execute_command' tool with clear description of shell type (bash, sh, zsh) as an optional parameter.
• Add confirmation/dry-run pattern to all write/delete/execute tools: require explicit 'confirm=true' parameter or return a 'confirmation_required' response with a summary of changes before executing.
• Document complete input schemas for all tools. For 'apply_patch', define 'type' as enum: ['unified', 'context', 'merge']. For 'MultiEdit', specify the structure of edits array with required fields.
• Add output schema documentation to every tool. E.g., 'read_file returns {content: string, line_count: number, truncated: boolean}'. Include pagination info for list tools.
• Implement error classification: return structured errors with 'code' (e.g., 'NOT_FOUND', 'PERMISSION_DENIED', 'INVALID_INPUT'), 'message', and 'recovery_hint' fields. E.g., 'File not found. Check path with describe_workspace or glob_files.'
