calculate_pressure_convert

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

No annotations are provided, so the description must convey behavioral traits. It only states 'Returns: {original}' which is vague and does not clarify whether the conversion is read-only, idempotent, or has side effects. The tool likely performs a simple calculation, but the description is insufficient.

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 relatively concise with three sentences. It front-loads the conversion action and use cases. However, the return value is ambiguously described as '{original}', which could be clearer. The structure is otherwise reasonable.

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?

Given the large number of sibling tools (including 'convert_pressure'), the description does not clarify which tool to use for pressure conversion. The unit list inconsistency (description includes kPa, MPa, torr while schema only has 6 units) creates confusion. The mention of 'list_bundles' is helpful but not enough to fully contextualize the tool within the family.

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 full coverage (100%) and good descriptions for all three parameters. The description redundantly mentions 'value, from-unit, to-unit' but adds no new meaning. It lists extra units not in the enum, which could mislead. The schema already handles semantics adequately, so the description provides little additional value.

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 it converts pressure between multiple units and lists use cases like engineering, weather, medicine. However, it does not distinguish itself from the sibling tool 'convert_pressure', and the listed units (kPa, MPa, torr) do not all appear in the input schema, potentially causing confusion.

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 mentions use cases (engineering, weather, medicine) and points to list_bundles for related calculators, but it does not explicitly state when not to use this tool or name alternatives. The difference from 'convert_pressure' is not addressed.

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