Single tool 'close_session' with empty input schema {} and minimal description. No parameter documentation, no output schema, no error handling guidance. Tool name lacks clarity on what 'session' means (browser? LinkedIn? auth?). Destructive operation with no confirmation pattern. Does not meet baseline standards for production tools.

• Add explicit input schema with at least one parameter (e.g., 'force_close: boolean' with description 'If true, forcefully terminate session even if cleanup fails. Default false for safety.')
• Expand description to 100-150 chars: 'Closes the active LinkedIn browser session and cleans up resources. Returns success status and cleanup details. Use before ending conversation to free memory and browser processes.'
• Document output schema: {success: boolean, message: string, cleanup_details: {cookies_cleared: boolean, browser_closed: boolean, temp_files_removed: boolean}}
• Add confirmation pattern: 'This is a destructive operation. Closing the session will end the LinkedIn connection. Confirm before proceeding.'
• Clarify error cases: 'If session is already closed, returns success. If cleanup fails, returns partial success with details. Retryable on timeout errors.'

Inferred effective spec: <=2025-11-25.

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