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

With no annotations, the description carries the full burden of behavioral disclosure, and it discloses nothing beyond a self-referential phrase. An agent cannot infer what operation is performed, what output to expect, or whether the tool has side effects.

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 only a few words, but it is under-specified rather than concise. Repeating the tool name adds no information, so every sentence (indeed every word) fails to earn 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?

Despite having no parameters and no output schema, the tool still requires a meaningful description to convey its purpose and return behavior. This definition provides none of that, leaving an agent completely unable to decide when or how to invoke it.

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 is empty with 0 parameters, so there is no parameter semantic gap for the description to fill. The baseline for 0 parameters is 4, and the description neither adds nor needs parameter detail.

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 is 'Connected Components: Connected Components', which merely restates the tool name without any verb or resource. It does not say whether this tool finds, counts, or visualizes connected components, and it is indistinguishable from graph-related siblings like x402-bfs or x402-adjacency-matrix.

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 given about when to use this tool or when to prefer a sibling. The name hints at graph connectivity, but there is no explicit or implicit context about prerequisites, input source, or comparison with alternatives.

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