SellerWallet_getTransaction

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

With no annotations, the description carries the full burden of behavioral disclosure. It adds the important caveat that the tool runs in the user's Kuudo deployment rather than in this environment, and 'Find' implies a read-only operation. However, it does not mention auth requirements, error behavior, or what the response contains.

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 very short with no fluff, and both the deployment warning and function statement are useful. The main downside is that the function statement is placed last, and 'Catalog entry' adds little on its own. Overall, it is concise and readable.

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?

This is a simple get-by-identifier tool, but there is no output schema and no annotation, so the description is the only source of context. It omits the parameter name, the identifier format, and any return-value information. The deployment caveat is helpful, but the description is incomplete for a tool that is meant to be invoked.

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 schema has zero properties but allows additionalProperties, while the description mentions looking up by 'the Amazon transaction identifier' without naming the exact parameter key. This leaves the agent unable to construct the call reliably. The description adds semantic context but fails to bridge the gap between the abstract identifier and a concrete parameter name.

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 clear verb and resource: 'Find a transaction by the Amazon transaction identifier.' This communicates the core operation unambiguously. However, it does not explicitly distinguish the tool from siblings like SellerWallet_listAccountTransactions or SellerWallet_getAccount beyond the resource name.

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 such as SellerWallet_listAccountTransactions or SellerWallet_getTransaction. The deployment caveat 'Runs in your Kuudo deployment, not here' is environment context, not usage guidance. No exclusions, prerequisites, or alternative routing are given.

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