execute_m2mcent_tool

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

With no annotations, the description carries the full burden. It adds genuine value by disclosing the financial cost ($0.01-$0.50 USDC), which is a meaningful behavioral trait not inferable from the name. However, it omits other behavioral traits for a dispatcher tool: no mention of side effects, failure behavior for unknown toolNames, response format, or external network calls.

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?

Two sentences with no filler: the first front-loads the primary purpose, the second adds the essential cost caveat. Every word 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?

This is a high-complexity tool dispatching to 1,004 heterogeneous microservices, with no output schema and no annotations to lean on. The description does not address how an agent should discover the correct toolName, what errors occur on invalid input, or what the response looks like — leaving a large surface area under-documented.

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 coverage is 100%, so baseline is 3. The description adds marginal context for toolName by noting that each microservice/node carries a varying fee, which helps agents weigh cost when selecting parameters. It adds nothing for payload beyond what the schema already states ('JSON stringified payload or text query').

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 ('Execute') and resource ('1,004 M2MCent microservices'), making the dispatch role clear. It implicitly differentiates from the sibling search_m2mcent_catalog by framing this as the execution counterpart to discovery, though it never names the sibling explicitly.

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 only usage guidance is the cost warning ('Fee varies per node'), which is a real consideration but not routing guidance. The description never tells the agent to use search_m2mcent_catalog first to identify a valid toolName, nor does it explain when to avoid execution or how to handle invalid tool names.

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