time_convert

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

The only behavioral disclosure is the cost '$0.001 USDC via x402.' No other details about output, conversion scope, or side effects are provided. The description carries the full burden since no annotations exist, and it underdelivers.

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 concise but the first part ('time convert — Converters tool') is redundant with the name and wastes a sentence. The cost sentence is useful but cannot compensate for the overall lack of substantive 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?

With no annotations, no output schema, and an opaque parameter structure, the description is grossly insufficient. The cost info is nice but does not enable an agent to correctly use the tool or understand its behavior.

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?

The input schema has a generic 'params' JSON object with no meaningful description, and the description adds zero information about required fields or structure. The agent is left completely in the dark about how to invoke the tool.

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 merely restates the tool name ('time convert') and labels it 'Converters tool' with no specification of what time conversions it performs. It fails to distinguish itself from the many other converter tools in the sibling list.

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?

There is no guidance on when to use this tool versus alternatives. With numerous converter siblings, more context is needed but entirely absent.

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