Two tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. upload_to_oss has a WRITE risk but no confirmation/dry-run pattern. Descriptions are present but generic (10-50 chars baseline; rubric expects 50-200 for LLM optimization). Parameters lack type constraints (enums, ranges). No output schema documented. Error handling returns raw error strings without recovery guidance. list_oss_configs has empty input schema (correct) but minimal description. Overall: functional but below production baseline.

• Document output schema for both tools. Specify: upload_to_oss returns {success: bool, url: string, ossConfigName: string, error?: string}; list_oss_configs returns {configs: [{id: string, region: string, bucket: string}]}.
• Add enum constraint to configName parameter. Populate from ossService.getConfigs() at registration time, or document that LLM must call list_oss_configs first to discover valid names.
• Expand tool descriptions to 50-200 characters. E.g., 'upload_to_oss: Upload a local file to Aliyun OSS. Specify target directory and optional filename. Returns public URL. Requires valid OSS config.' and 'list_oss_configs: Discover available Aliyun OSS configurations (region, bucket, auth). Call this first if you don't know which config to use.'
• Implement confirmation pattern for upload_to_oss: add optional 'dry_run' parameter (bool, default false). When true, validate file and config but do not upload. Return what would be uploaded.
• Enhance error responses with recovery guidance. E.g., 'File not found: /path/to/file. Check the path and try again.' or 'Config 'prod' not found. Call list_oss_configs to see available configs: default, staging, prod-backup.'

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