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

The description states the tool 'gets' information, implying a read-only operation, but the annotations declare destructiveHint=true and readOnlyHint=false. This is a direct contradiction, so the description fails to provide trustworthy behavioral context. Annotation contradiction flag set to true.

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 front-loads the purpose and lists the specific return values. Every word contributes to understanding the tool, with no unnecessary filler.

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 simple tool with no parameters and no output schema, the description adequately lists the return fields. However, it does not address the behavioral implications of the contradictory annotations (destructiveHint, readOnlyHint=false), leaving the agent uncertain about side effects. This gap prevents a higher score.

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 zero parameters, so the baseline is 4. The description adds context about what the tool returns, which is useful given no output schema, but there are no parameter semantics to explain.

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 uses a specific verb 'Get' and clearly identifies the resource as 'current MCP server connection info', listing the exact fields returned (network name, node address, latest block). This clearly distinguishes it from sibling tools like get_block or get_account.

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 intended use is implied by the description—use when you need connection info—but there is no explicit guidance on when to use this tool versus alternatives (e.g., get_block for block details). No exclusions or alternatives are mentioned.

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