get_card_transactions

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

No annotations are provided, and the description offers no behavioral details. It does not mention pagination, date filtering, read-only assurance, rate limits, or any other operational characteristics, leaving the agent without essential safety and behavior context.

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 and concise, but it is under-specified. It lacks substance and does not earn its place by conveying necessary context beyond what the name already implies.

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 five-parameter schema and no output schema, the description is severely incomplete. It fails to mention pagination, date range, required card_id, or differences from sibling tools, leaving crucial context missing for an agent to use 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?

All five parameters are described in the schema with 100% coverage, so the baseline is 3. The description adds no additional nuance to the parameters, but the schema already provides adequate descriptions for each field.

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 fetches credit card transactions, with a specific verb and resource. However, it does not distinguish this from the sibling tool 'get_transactions', so it lacks sibling differentiation.

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 guidance is provided on when to use this tool versus 'get_transactions' or other alternatives. The description lacks any contextual cues for selecting this tool over others.

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