This server has 6 tools with mixed quality. Core async management tools (list_pending_tasks, get_task_result, cancel_task) have minimal schemas and descriptions under 50 chars, falling well below the 194-char baseline. The example tools (add, multiply, slow_operation) are better documented but still lack parameter descriptions and comprehensive output schemas. No tool has a documented return type or output schema structure. Parameter naming is reasonable but descriptions are sparse. Error handling is not visible in the provided code. The server is STDIO-only, which caps protocol readiness at 50 and severely limits production utility.

• Expand tool descriptions to 100-200 chars. For list_pending_tasks, add: 'Returns the IDs and execution status of all tasks currently running on the async bridge. Call this to check if a long-running task is still in progress before calling get_task_result.'
• Document all return types as JSON schemas. Example for get_task_result: { type: 'object', properties: { status: { type: 'string', enum: ['completed', 'failed', 'timeout'] }, result: { type: 'any' }, error: { type: 'string' } }, required: ['status'] }
• Add descriptions to nested parameter fields. For the 'arguments' param in add/multiply: { a: { type: 'number', description: 'First operand' }, b: { type: 'number', description: 'Second operand' } }
• Enhance 'sync' parameter description: 'Set to true to force synchronous execution (blocking). Default false (async). Use sync=true when you need the result immediately; async is faster for non-blocking workflows.'
• Add error recovery guidance in tool descriptions. E.g. for cancel_task: 'Cancels a pending task by ID. If the task has already completed or timed out, returns an error with code TASK_NOT_FOUND, verify the task exists with list_pending_tasks first.'
• Validate task IDs early and return actionable errors: 'Task ID "invalid-uuid" not found. Call list_pending_tasks to see available task IDs.' instead of generic exceptions.
• Add per-tool error codes and their meanings to documentation (e.g., INVALID_DURATION, TASK_TIMEOUT, INVALID_ARGUMENTS) so LLMs can anticipate failures.
• Include chaining IDs in responses. When get_task_result returns a result, include task_id in the response so the agent can reference it in cancel_task or logs without a separate lookup.

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