Verify the ContextMint Bridge connection end-to-end

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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint, so the safety profile is covered. The description adds genuinely useful context beyond them: no auth required, that it touches your signed-in browser tab, elapsed round-trip timing, and the four failure classes the hint discriminates between.

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 the core mechanism, then the returned diagnostics, then the usage trigger. Slightly dense in the first sentence's long list of diagnostic fields, but every clause carries information and nothing is wasted.

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?

There is no output schema, and the description fully enumerates the return shape (bridge role, port, version, link state, elapsed time, hint), so an agent knows exactly what it gets back. Combined with the trigger guidance and auth note, nothing needed to call it correctly is absent.

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, so per the rubric the baseline is 4; there is no parameter semantics to clarify and the description does not invent any. Nothing here is missing or misleading on the parameter axis.

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 and resource: it round-trips a small public URL (/robots.txt) through ContextMint Bridge and returns diagnostics. It also enumerates what the diagnostics contain, so an agent can distinguish it immediately from the tock_* data tools in the sibling list.

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 call it: 'Call this when a real tool fails and you want to know which hop broke.' That is a clear trigger condition, though it does not name a specific alternative diagnostic tool to prefer and leaves the 'when not to call' case implicit.

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