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

With empty annotations, the description carries full burden for behavioral disclosure. It only labels the tool as an alias and gives a use case. It does not disclose side effects, local setup requirements, state changes, or return behavior. The agent cannot infer what actually happens when invoking this tool.

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 extremely concise: two sentences, each earning its place. It names the alias and gives the key usage condition. No filler or repetition.

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 tool with 43 parameters, no output schema, and empty annotations, this description is severely incomplete. It does not explain the setup process, required inputs, expected outcomes, or how to use the alias effectively. The agent would need to rely on the sibling tool's documentation, which is not mentioned beyond its name.

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 only 33%, and the description provides zero parameter information. The tool has 43 parameters, but the description does not map any of them or point to the canonical tool's parameter docs. The agent has no guidance on which parameters to supply for the alias.

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 states a specific verb+resource: 'Alias for setup_local_wallet_bridge.' It clearly differentiates by adding the use case: 'Use when the user wants their wallet to stay local while the agent uses Wisely x402 payment sessions.' This distinguishes it from other bridge setup tools and gives a concrete purpose.

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 description provides an explicit condition for use: 'Use when the user wants their wallet to stay local.' It also names the canonical sibling tool (setup_local_wallet_bridge), giving the agent a clear alternative to consult for canonical behavior. This is strong guidance.

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