timezone_set

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

No annotations are provided, so the description carries the full burden. It discloses only the basic action and mentions a 'confirm' argument, but does not explain effects, reversibility, side effects, or what confirming actually does. This is thin for a state-changing operation.

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 appropriately short and front-loaded with the core purpose. The args section is compact, though 'confirm: Required' is too terse to be fully clear. Overall it wastes no words.

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 state-changing tool with no annotations and only 0% schema coverage, the description is incomplete. It lacks usage context, behavioral disclosure, and clear confirmation semantics. The presence of an output schema helps with return values, but not with the key ambiguity around the confirm parameter.

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 does define 'timezone' usefully as an IANA name with an example, but 'confirm: Required' is ambiguous and contradicts the input schema, which lists only 'timezone' as required and gives 'confirm' a default of false. The description does not explain what value confirm should take.

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 states a clear verb and resource: 'Set server timezone.' This distinguishes it from sibling read-only tools like timezone_current and timezone_list, though it does not explicitly reference them.

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 is given about when to use this tool versus alternatives, no exclusions or prerequisites are mentioned, and the sibling timezone tools are not referenced. The intended use is implied by the verb 'Set' but not explicitly explained.

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