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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered by structured data. The description adds only the return content (labels + profile); it does not clarify whether 'Track' means a one-shot snapshot or a persistent subscription (the name and verb otherwise suggest ongoing monitoring), nor does it mention rate limits or auth. Useful but thin beyond the annotations.

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?

A single front-loaded sentence with no filler, and the resource and return payload come first. It is arguably too terse for a tool with four close siblings, but there is no wasted verbiage.

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 an output schema present, the description need not explain return values, and the input schema fully documents both params. The remaining gap is routing context: nothing explains how this differs from monitor.whale.alerts / monitor.watch.address, which is the main thing an agent needs to pick correctly.

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 description coverage is 100% for both parameters, including the chain default of 'base', so the schema already carries the parameter burden and baseline 3 applies. The description adds no format hints (e.g., address casing/checksum, supported chains) beyond what the schema states.

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 (Track) plus resource (a specific whale address) and names the payload (Address Intelligence labels and wallet profile), so the agent knows what it gets back. It does not, however, distinguish itself from near-identical siblings such as monitor.whale.alerts, monitor.watch.address, or wallet.profile, which a reader would have to disambiguate from the name alone.

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?

There is no statement of when to use this tool versus monitor.whale.alerts, monitor.watch.address, or wallet.profile, and no exclusions or prerequisites. The only implied usage is the word 'specific', which is too weak to route an agent among the several overlapping whale/wallet tools.

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