Two tools with clear verb-noun naming (search_images, get_image_details) and reasonable descriptions (95-110 chars). Input schemas present with types and descriptions for all parameters. However, output schemas are not documented in the source code provided, and parameter descriptions lack detail on constraints, formats, and error recovery guidance. No tool annotations (readOnlyHint, destructiveHint) despite both being read-only operations. Error handling not visible in provided code.

• Document output schemas for both tools. Specify fields returned by search_images (e.g., results array with id, title, url, photographer, width, height, source) and get_image_details (e.g., detailed metadata including license, photographer_url, description). Include total_count and pagination info for search_images.
• Add min/max constraints to numeric parameters: per_page (1-100, default 20), page (1+, default 1). Add format/length constraints to string parameters: query (1-500 chars), image_id (format: 'provider_id', e.g., 'pexels_123456').
• Apply readOnlyHint=true to both tools via tool annotations to signal to agents that these are safe, non-destructive operations.
• Add error recovery guidance to descriptions. E.g., 'If a provider is unavailable, results from other providers are returned. If all providers fail, returns empty results with error details.'
• Enhance provider parameter description: 'Image provider to search. Use "all" to search all available providers (Pexels, Unsplash, Pixabay) and aggregate results. Use a specific provider name to limit results to that source.'

Inferred effective spec: 2026-07-28+.

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