get_product_specs

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

Annotations already declare readOnlyHint=true, so the safety profile is clear. The description adds only 'Detailed specs/highlights', which is minimal additional behavioral context. With annotations covering the core trait, the description does not provide new insights such as response format or performance characteristics.

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 a single, well-structured sentence that conveys the essential purpose. It is appropriately sized with no unnecessary words. Could potentially include more detail without becoming verbose, but as is it is efficient.

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 tool has one parameter and no output schema, the description is minimal but functional. However, considering the number of sibling tools (11), more context about what kind of specs are returned would help an agent select correctly. Not a 4 because it lacks completeness for decision-making.

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%, listing acceptable values for the 'id' parameter. The description mentions 'by id' but adds no new meaning beyond what the schema already provides. Baseline score of 3 is appropriate as the schema does the heavy lifting.

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 retrieves 'detailed specs/highlights for one product line by id'. The verb 'get' and resource 'specs/highlights' are specific, and the scope is clear. However, it does not differentiate from the sibling tool 'get_drill_pipe_specs', which might be a subset, so not a 5.

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 on when to use this tool versus alternatives like 'get_drill_pipe_specs' or 'list_products'. The description lacks any context about prerequisites or preferred use cases, making it hard for an agent to decide among siblings.

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