Verify the ContextMint Bridge connection end-to-end

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

Annotations already cover readOnlyHint, openWorldHint, and idempotentHint, but the description adds substantial value: it discloses the exact return fields (bridge role, port, version, extension link states, elapsed time) and the plain-English hint categories that distinguish failure modes. It also states 'Read-only, no auth required,' reinforcing the safety profile with concrete behavioral detail.

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?

Front-loaded with what the tool does, followed by return details and usage guidance, so the agent hits the important content first. It is dense and slightly long, but every clause carries diagnostic information rather than 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?

With no output schema, the description fully carries the burden of explaining return values and failure-mode interpretation, which it does in detail. An agent has everything needed to call this correctly and interpret the diagnostics.

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 tool takes zero parameters, which is the baseline for a 4; there are no arguments whose semantics need explaining. The description correctly signals the parameterless nature by describing an implicit fixed target URL (/robots.txt).

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?

States a specific verb (round-trips a small public URL) and resource (ContextMint Bridge connection) and enumerates the diagnostics returned. This is clearly distinguishable from all sibling tools, which fetch account/pro/review/trade data rather than verifying connectivity.

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?

Explicitly says when to use it: 'Call this when a real tool fails and you want to know which hop broke.' This routes the agent correctly relative to the data-fetching siblings. It doesn't name a specific alternative tool or an explicit when-not-to-use, so it falls just short of a 5.

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