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 mentions constant pressure but does not disclose the underlying assumption of ideal vapor/liquid behavior (which is in the tool name but not described), nor any limitations, required conditions, or error scenarios. For a thermodynamic calculation, this is a significant gap.

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 only two sentences, which is concise, but the second sentence largely repeats the first ('first drop of liquid condenses' vs 'vapor will begin to condense'). It is front-loaded with the core purpose but wastes a sentence on redundancy. It could be tightened while preserving clarity.

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 complex thermodynamic calculation with no annotations, the description is incomplete. It does not mention the ideal gas/liquid assumption, which is central to the tool's applicability, nor does it specify constraints like requiring multiple components or the role of pressure. The output schema exists, so return values are covered, but the description leaves critical context (e.g., that it only applies to ideal systems) missing.

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%, so the baseline is 3. The description adds minimal value beyond the schema: it implicitly references pressure and components but does not explain how they should be used together (e.g., that components must be a vapor mixture, or what solver_method does beyond its enum). The description does not compensate for any ambiguity, but the schema already documents each field.

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 determines the dew temperature (first drop of liquid condenses) at a given pressure, using specific language ('determines', 'find the temperature'). The resource is explicit (dew temperature) and the action is distinct from siblings like bubble temperature or pressure calculations, so an agent can distinguish it without opening other definitions.

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 gives clear context: 'used to find the temperature for a given pressure at which the vapor will begin to condense.' However, it does not mention alternatives or explicitly state when not to use it (e.g., for bubble point or non-ideal systems). It implies the scenario (constant pressure, vapor condensing) but does not contrast with sibling tools.

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