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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so the safety profile is covered. The description adds that entries are returned alongside each template, but says nothing about ordering, size, or how entries are formatted (and no output schema exists to compensate).

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 purpose and the when-to-use instruction are both front-loaded, and nothing is redundant. The long parenthetical enumerating every template family is a little heavy but does real work by telling the agent which wheels exist.

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 single optional-parameter read tool with full annotation coverage and no output schema, the description says what it returns at the level of content and when to reach for it. Only the shape/ordering of the returned entries is left unspecified.

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 100% and the category parameter's own description supplies example values. The description never mentions the filter, though the listed families loosely hint at valid categories; baseline 3 applies when the schema carries the load.

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?

Uses a specific verb (List) plus resource (ready-made wheel templates) and enumerates the template families, so an agent knows exactly what comes back. It is clearly distinct from spin_wheel (which spins) and create_wheel_link (which shares).

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?

States the triggering condition explicitly: call it before spin_wheel when the user names a common wheel but supplies no options. It also names the follow-up tool, so the sequence is unambiguous.

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