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

With no annotations provided, the description carries the full burden of behavioral disclosure. It warns about potential value loss, requires a zero balance, and mentions a confirmation step. These are important behavioral traits. However, it does not detail the exact mechanics of the opt-out or whether the operation is reversible, so it is not fully transparent.

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 reasonably structured with @param lines, but it contains clear redundancy: the first sentence is repeated verbatim, and the `account_fk` phrasing is duplicated. The @return line ('a json object') adds little value. Tightening the repeated content would make it more concise while preserving the useful parameter details.

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 moderately complex tool with no annotations, the description covers purpose, parameters, safety warnings, and confirmation. It lacks explicit differentiation from sibling tools or details about the exact return structure, but the output schema exists, so the description is complete enough for an agent to select and invoke the tool 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?

Despite 0% schema description coverage, the description thoroughly documents all four parameters. It clarifies that `account_fk` is a database integer, not an account address, and cannot be 0. It also specifies the source for `token` and how to find `asset_id`. This goes well beyond the bare schema and gives an agent the necessary details to correctly supply parameters.

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 clearly states the tool's action: 'Opts the blockchain wallet out of holding a digital asset.' This specifies a concrete verb and resource, and the action is distinguishable from the sibling tool `netfluid__crypto_optin`, which performs the opposite operation.

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 explicit usage context: a confirmation step ('Confirm (yes/no) before executing') and a critical precondition ('Ensure that the blockchain wallet has a zero balance... before performing this action as value may be lost'). While it does not mention alternatives or exclusions, the preconditions and confirmation flow give clear guidance on when and how to use the tool.

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