Transactions Download Transaction Attachment

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

Annotations declare readOnlyHint true, but the description adds no behavioral details beyond that. It doesn't mention that the tool returns a file or any side effects, leaving the agent guessing about the exact behavior.

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 but under-specified. It consists of only three words, which is too brief to be helpful. Conciseness should not come at the cost of necessary detail.

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?

Given the complexity of 5 parameters, no output schema, and multiple sibling tools, the description fails to provide complete context. It does not explain the return shape, the meaning of parameters, or how the tool differs from related ones.

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 adds no information about parameters. With only 40% schema description coverage, the description should compensate for missing parameter documentation, but it does not.

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 verb 'download' and resource 'transaction attachment.' However, it does not clarify what 'download' entails (e.g., file content vs. URL), and it fails to distinguish from the sibling tool 'transactions_get_transaction_attachment.'

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?

No usage guidelines are provided. The description gives no context on when to use this tool over alternatives like 'get_transaction_attachment' or 'upload_transaction_attachment.'

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