A4.5/5.0

Behavior5/5

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

Beyond the readOnlyHint annotation, the description adds a meaningful security guarantee: the full card number and CVV are never returned by this or any other tool. It also specifies that only the last four digits are exposed, which is critical behavioral context for an agent handling sensitive card data.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences front-load the core behavior (returns one card by id) and its key fields, then add the read-only safety and the never-returned data guarantee. Every sentence carries distinct value with zero redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has a single parameter, an output schema, and annotations covering safety. The description covers the essential scope, the data sensitivity limitation, and the read-only nature, leaving nothing an agent needs to invoke it correctly unexplained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with the cardId parameter already described as a UUID value wrapper. The description adds only 'by id,' which mildly reinforces the parameter's role but does not materially enhance the schema's explanation. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Returns one card by id' and enumerates the exact fields returned (label, type, state, limits, last four digits). This clearly distinguishes it from siblings like card_get_list_cards or card_get_card_spend, which cover different resources and scopes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly establishes when to use it: when you have a specific card id and need its details. It does not explicitly name alternatives or state exclusions, but the 'one card by id' framing makes the use case unambiguous without confusing it with list or spend tools.

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