Single tool 'upgrade_apps' has critical definition gaps. Tool name lacks clarity (does not follow verb_noun pattern clearly, 'upgrade_apps' is acceptable but vague on scope). Description is minimal (47 chars, below 10-char baseline for A+ tools). No parameter descriptions, no output schema documentation, no error handling guidance. Tool performs destructive operation (shell command execution) with no confirmation, dry-run, or permission checks. No input validation or sanitization against command injection. This server would not pass code review.

• Add explicit input schema with typed parameters. Example: accept 'dry_run' (boolean, default false) and 'timeout_seconds' (integer, 1-3600, default 300) to enable safe exploration before execution.
• Expand description to 100-200 chars explaining WHAT the tool does, WHEN to use it, and that it modifies system state. Example: 'Executes the update-apps.sh script to upgrade all installed applications. This is a destructive operation that modifies system packages. Use dry_run=true to preview changes first.'
• Document output schema: return structured object with {success: boolean, stdout: string, stderr: string, exit_code: integer, duration_seconds: float}.
• Implement command injection protection: validate COMMAND_FOLDER_PATH against a whitelist of allowed directories, or use subprocess.run() with shell=False and explicit argument list instead of shell=True.
• Add confirmation pattern: require explicit 'confirm=true' parameter for non-dry-run execution, and return actionable error messages like 'Dry-run succeeded. Call again with confirm=true to apply changes.'
