remind_get_classes

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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds real value beyond that by disclosing the shape of the payload (join code/url, member/message/owner counts, history and messaging flags) and permission-scoped output ('what this account may edit').

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?

One dense sentence with the verb and resource front-loaded and the field list trailing. Every clause earns its place, though the field enumeration is long and could be trimmed.

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?

For a read-only, single-parameter getter with no output schema, the description's return-field enumeration compensates well for the missing output schema. Only the lack of explicit routing against remind_list_entities keeps it from being fully 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?

There is a single parameter with 100% schema description coverage, so the schema already documents the uuid array and its provenance. The description adds no format or sourcing detail beyond 'by uuid', which is the expected baseline when schema coverage is complete.

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?

States a specific verb and resource ('Get full detail for one or more classes by uuid') and enumerates the returned fields, so an agent knows exactly what it gets. It does not explicitly name the sibling remind_list_entities as the source of uuids (only the schema does), so it falls short of full sibling differentiation.

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?

The phrase 'by uuid' implies this is a follow-up lookup rather than a discovery call, and the schema notes uuids come 'from remind_list_entities', but the description itself gives no explicit when-to-use or when-not-to-use guidance versus remind_list_entities or remind_list_chats.

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