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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds that the catalog includes read/write annotations for each operation, which is useful context, but it does not disclose other behavioral traits like output format or rate limits.

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?

The description is a single, well-structured sentence that is front-loaded with the core purpose and contains no redundant or filler content.

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 simple read-only catalog tool with annotations covering safety and a schema listing category enums, the description is nearly complete. It could mention that omitting categories returns all operations, but this is a minor gap given the tool's simplicity and lack of an output schema.

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 description coverage is 0%, so the description must compensate. It only says 'by category,' which vaguely maps to the 'categories' parameter but does not explain that it is an optional array with a max of 8 values, nor does it clarify the meaning of the enum categories.

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 clearly states the tool's function: browsing MagicInterview operations by category and returning names, descriptions, and read/write annotations. It uses a specific verb (Browse) and resource (operations), but does not explicitly differentiate itself from sibling tools like learn_tools or read_tool.

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 description implies usage by saying 'Browse available MagicInterview operations by category,' but it gives no explicit when-to-use guidance, no prerequisites, and no comparison to alternatives such as learn_tools or read_tool.

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