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 does not state whether this operation is read-only, whether it returns data, whether it costs anything, or what 'signed' and 'print' mean operationally. 'Free' hints at pricing but is too ambiguous to be useful.

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 short, but this is under-specification rather than conciseness. The fragment 'The signed Dated SIU print' is not a complete or informative sentence, and 'Free — citation is the business' adds no operational clarity.

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 tool with no output schema, no annotations, and two undocumented parameters, the description is severely incomplete. An agent cannot correctly invoke this tool or interpret its purpose from the information given.

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 0% and the description provides no meaning for the 'date' and 'version' parameters. An agent has no way to know what formats are expected, what values are valid, or how these parameters affect the result.

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 'The signed Dated SIU print. Free — citation is the business.' is cryptic and does not state what the tool does. It does not mention retrieving an index, any clear action, or resource, and it fails to distinguish itself from siblings like get_quote or verify_receipt.

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?

There is no guidance on when to use this tool versus alternatives. No context, use cases, exclusions, or conditions are provided, leaving an agent unable to decide between get_index and its sibling tools.

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