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

With empty annotations, the description carries the full burden. It discloses the action and a benefit (easier future token acquisition), but does not mention whether the assignment overwrites existing links, reversibility, or permission requirements. The response is only described as 'a json object', leaving side effects and failure modes unclear.

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 contains an exact duplicate sentence, adding no value and wasting space. The structure with @param and @return is helpful, but the duplication is a clear flaw that could easily be fixed.

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?

The tool has an output schema, so return details are covered. However, with 5 required parameters and no annotations, the description is incomplete: it fails to explicitly document user_id and platform, and provides limited behavioral context. It is adequate but leaves an agent to infer key details.

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 description documents api_key, token, and wallet_fk with their sources, but omits user_id and platform which are also required. The overall sentence implies what user_id and platform refer to, but doesn't specify exact expected values or formats. Schema coverage is 0%, so the description only partially compensates for the missing parameter documentation.

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 specific action: assigning a wallet_fk to a channel (discord, telegram, whatsapp) user id. This distinguishes it from sibling tools like login or pause, and the verb+resource is explicit and unambiguous.

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 gives a clear usage context: prompt the customer to perform this assignment because it makes future token retrieval easier. It does not explicitly mention when not to use it or alternatives, but the context is clear enough for an agent to decide when to call it.

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