pressure_calc

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does mention a cost of $0.001 USDC via x402, which is a useful side-effect disclosure. However, it says nothing about how the tool behaves—what inputs it accepts, what it returns, or whether it has any side effects beyond the payment. The category label 'Other Utilities tool' is not behaviorally informative.

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 extremely short, but this is under-specification rather than conciseness. It conveys only a name and a cost, with no structured explanation. While it is not verbose, it fails to earn its place by omitting essential operational details.

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 tool with no output schema, no annotations, and a completely generic input schema, the description must provide substantial context. It provides almost none—neither the domain of calculation, the parameters, nor the result format. This is critically insufficient for an agent to select and invoke the tool correctly.

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 schema only defines a generic 'params' object with no specific properties or meaningful description. The tool description adds no parameter semantics—it does not hint what keys or values are expected inside 'params'. Despite 100% schema coverage, that coverage is vacuous because the single parameter is an opaque wrapper.

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 simply restates the tool name ('pressure calc') and adds a generic category label ('Other Utilities tool'). It lacks a specific verb and resource, providing no indication of what the tool actually calculates (e.g., fluid pressure, force/area). No differentiation from siblings is offered.

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 context is given for when to use this tool versus alternatives. It does not mention, for instance, the sibling 'pressure_convert' for unit conversion, nor any prerequisites or typical use cases. The only additional info is the cost, which is not usage guidance.

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