search_m2mcent_catalog

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

No annotations are provided, so the description bears the full burden of behavioral disclosure. It only says 'Search', which implies a read-only operation, but it does not state whether results are limited to the 1,004+ services, whether pagination exists, or what the response contains. Minimal behavioral context is added beyond the tool's name.

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 that is front-loaded with the action and resource, with no redundant words or filler. Every part of the sentence earns its place.

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 one-parameter search tool, the description covers the invocation sufficiently: the agent knows what to search and where. However, there is no output schema and no mention of what the search returns, which creates a gap for an agent that needs to interpret results or select matching services to execute.

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%, and the query parameter already includes an explanatory description with examples ('pdf', 'crypto', 'vision'). The tool description itself adds no parameter detail beyond the schema, so the baseline score of 3 applies.

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 states a specific verb ('Search') and a specific resource ('M2MCent Universal Catalog of 1,004+ Agentic Services'), making the tool's function immediately clear. It does not explicitly name the sibling execute_m2mcent_tool, but the search-vs-execute contrast is evident from the sibling's name.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no direct comparison to execute_m2mcent_tool. The only usage signal is the phrase 'Search the... Catalog', which implies this tool is for discovery before execution, but that remains an inference rather than stated guidance.

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