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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the agent knows this is a mutating and potentially destructive operation. The description adds minimal behavioral context by specifying the action is 'with the wallet service', but it does not clarify side effects, whether registration overwrites existing data, or what happens on success. It does not contradict 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?

The description is a single sentence of eight words, front-loaded with the key verb and resource. There is zero redundancy or filler, making it highly concise and easy to parse.

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?

Despite having a rich schema and annotations, the description leaves significant gaps: it doesn't explain what 'agentic wallet addresses' are, when this tool should be used (e.g., during onboarding), or what the effect of 'registering' is given the destructiveHint. With no output schema and a complex nested parameter structure, the description alone is insufficient for an agent to fully understand the tool's purpose and side effects.

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 (wallets and mcp_token), so the schema already documents their meanings and requirements. The description adds no additional parameter-level semantics, so the baseline score of 3 applies.

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 uses a specific verb ('Register') and a specific resource ('agentic wallet addresses with the wallet service'), which clearly states the tool's function. However, it does not explicitly distinguish itself from sibling wallet-binding tools like dex_wallet_bind_exchange_uid or dex_wallet_replace_binding, and the term 'agentic wallet addresses' is somewhat ambiguous without additional context.

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 no guidance on when to use this tool versus alternatives, nor does it mention prerequisites such as needing to log in first or requiring a token. While the schema field description for mcp_token mentions the login requirement, the tool description itself offers no contextual usage hints.

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