The server has solid naming conventions (all tools start with action verbs: check_, search_, get_, list_, trash_, restore_) and consistent descriptions. However, there are significant gaps in output schema documentation, parameter descriptions lack detail, and error handling is minimal. Most tools have good descriptions (150-200 chars) but no guidance on what fields to expect in responses. Parameters like 'query' in search_photos lack format/constraint details. Error responses return raw exceptions rather than actionable recovery guidance.

• Document output schema for all list-returning tools. Create a response model (e.g., PhotoMetadata with fields: id, name, date, size, type, location) and include in docstrings. This lets LLMs reliably extract and chain results.
• Add enum constraints to parameter descriptions. Instead of 'media_type: "PHOTOS" or "VIDEOS"', declare media_type as enum["PHOTOS", "VIDEOS"] in the schema and mirror in the description.
• Replace raw exception tracebacks with classified error responses. E.g., on cookie failure: {"error": "auth_failed", "reason": "Cookies expired or invalid", "action": "Set AMAZON_PHOTOS_COOKIES env var or update ~/.config/amazon-photos-mcp/cookies.json"}
• Add pagination support to search_photos, get_photos, get_videos, search_by_date, search_by_things. Introduce offset/limit or cursor-based pagination, and return total_count. Update max_results to represent the per-page limit.
• Implement a confirmation mechanism for destructive operations. Add a dry_run parameter to trash_items and restore_items, or create a separate confirm_trash operation that requires explicit affirmation before modifying state.
• Include response chaining identifiers. Ensure search_photos, get_photos, get_videos return node_id (or equivalent unique key) so results can be passed directly to trash_items or restore_items without extra lookups.
• Document idempotence. State in tool descriptions whether repeated calls with the same parameters return identical results and whether they are safe to retry. This is especially critical for trash_items and restore_items.
