search_sets

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, so the description adds value by specifying return fields and optional pagination. However, it doesn't disclose any other behavioral traits (e.g., rate limits, default pagination behavior, whether it returns all sets or requires filtering).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with action and outcome, no filler. Could be slightly more efficient by removing 'optionally paginated' if not critical, but overall concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Describes return fields, which compensates for lack of output schema. However, missing details like sorting, filtering capabilities, and whether it returns all sets or requires input criteria. For a simple list tool with 2 optional params, it's moderately complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 2 parameters (page, limit) with 0% description coverage. The description says 'optionally paginated' which hints at their purpose, but doesn't explain meaning or relationship beyond what the schema's numeric constraints imply.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states it lists MTG sets with specific return fields (code, name, release date, type, aggregate prices), using a clear verb+resource structure. It distinguishes from sibling tools like 'get_set' (single set) and 'search_cards' (cards).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives like 'get_set', 'search_cards', or other list tools. Only mentions optional pagination but doesn't provide context for selection among siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
