Critical gaps across all dimensions. Tool definitions lack proper schemas, descriptions are minimal (10-20 chars), and parameter documentation is absent. The 'bash' tool is particularly dangerous, no input validation, no error guidance, no permission framework visible in the tool definition itself. 'read_file' and 'write_file' lack path traversal protection documentation. 'echo' is trivial. No tool returns structured output schemas. Error handling is absent from tool definitions. Naming follows verb_noun convention (positive), but descriptions fail to explain WHEN to use each tool or what it returns.

• Add output schema documentation to all tools. E.g., bash should return {stdout: string, stderr: string, exit_code: number, duration_ms: number}. read_file should return {content: string, size_bytes: number, encoding: string}.
• Expand tool descriptions to 50-200 chars explaining WHAT, WHEN, and WHAT IT RETURNS. E.g., 'Execute shell commands in the current working directory. Returns stdout, stderr, and exit code. Use for system queries and file operations; prefer read_file/write_file for file I/O. Destructive commands require confirmation.'
• Add parameter constraints and validation rules to descriptions. E.g., 'path: Absolute or relative file path (no symlink traversal outside CWD). Max 4096 chars. Must be readable/writable by agent process.'
• Implement and document error classification. E.g., bash should return {isError: true, errorType: 'permission_denied|timeout|not_found|syntax_error', suggestion: 'Try with sudo' or 'Check file exists'}.
• Add permission framework documentation to tool definitions. Specify required scopes (e.g., bash requires 'exec:shell', read_file requires 'read:filesystem'). Document how the Policy.Decide() method gates access.
