get_card_cvc2

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

The description adds 'encrypted endpoint' indicating security, but lacks details on side effects, authorization needs, or rate limits. Since no annotations exist, more behavioral context would be beneficial.

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?

Two concise sentences: first stating purpose, second adding encryption context. No unnecessary words.

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?

Adequate for a simple retrieval tool, but lacks description of return data. Without output schema, mentioning what details are returned (e.g., CVC2 value, expiration) would improve completeness.

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 coverage is 100% with concise parameter descriptions. The tool description does not add further meaning beyond what the schema already provides.

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 action ('Gets the details') and the resource ('a specific generated CVC2 code'), distinguishing it from sibling tools like create_card_cvc2 and list_card_cvc2.

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?

Usage is implied (retrieve details of a specific CVC2), but no explicit guidelines on when to use this over alternatives (e.g., list_card_cvc2) or when not to use it.

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