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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description's only additional context is the TraderSpy smart-money scope, which is modest added value rather than behavioral disclosure about auth, limits, or freshness.

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?

One sentence, front-loaded with the usage trigger, with no redundant restatement of the tool name or title. Every clause earns 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?

With an output schema present, the description need not describe return values, and the rich annotations cover safety. For a zero-param read tool the trigger-plus-scope statement is nearly sufficient, though it could note what the exchange list is used for downstream.

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 there is nothing for the description to clarify; the baseline for a parameterless tool applies. The description correctly makes no claims about arguments it does not have.

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 the resource precisely ('which exchanges are currently available in TraderSpy smart-money tracking'), so an agent knows this returns the set of tracked exchanges. It does not explicitly contrast with the similar-sounding sibling get_tracked_symbols, but the domain qualifier 'smart-money tracking' is enough to distinguish scope.

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?

Provides a clear user-intent trigger ('when the user asks which exchanges are currently available'), which is a usable routing rule. It stops short of naming alternatives or when-not-to-use conditions, so it falls below the explicit-alternatives bar.

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