search_by_parameters

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

No annotations are present, so the description must carry the full burden. It only says 'Search parts' but does not disclose whether it is read-only, any side effects, authentication needs, pagination behavior, or results format. The output schema exists but is not referenced. Minimal transparency.

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 sentence, which is concise but lacks any structure or front-loaded key points. It is not verbose, but it is also not sufficiently informative. A score of 3 reflects minimal adequacy.

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 complexity of the 'parameters' object (nested with free-form keys) and the presence of many sibling search tools, the description is not complete. It does not explain how to construct the parameters, provide examples, or mention the output schema. The agent would need significant implicit knowledge to use 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 input schema has 100% description coverage for all three parameters. The description adds no extra meaning beyond what the schema provides, such as clarifying how to structure the 'parameters' object or the purpose of 'category'. Baseline score of 3 is appropriate.

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 verb 'Search' and the resource 'parts', and indicates the search is 'by specific parameters'. However, it does not distinguish this tool from the sibling tool 'search_parts', which likely serves a similar purpose. The lack of differentiation reduces clarity.

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 is provided on when to use this tool versus alternatives like 'search_parts' or 'find_alternatives'. There is no mention of prerequisites, when not to use it, or how it differs from other search-related tools.

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