get_data_key

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Get details' without confirming this is a read-only operation, what fields are returned, or whether special permissions or error cases apply. This adds minimal context beyond the tool name.

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 a single, front-loaded sentence with no redundant words or filler. It clearly conveys the action and resource in the most efficient way possible, earning full marks for conciseness.

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 simple getter with one parameter and no output schema, the description is adequate but not complete. It omits details about the return value, error handling, and the fact that this is a read-only counterpart to create/update/delete data key tools. A more complete description would mention these aspects.

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 input schema already describes the single 'id' parameter with a description ('Data key ID'), achieving 100% schema coverage. The description adds no additional meaning beyond implying that a specific data key is identified by its ID, which is already in the schema. Baseline 3 applies.

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 'Get' and the resource 'data key', with 'specific' indicating a single entity rather than a list. This distinguishes it from list_data_keys, though it does not explicitly name sibling tools like get_data_key_target; however, the resource is clearly different.

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 list_data_keys, create_data_key, or get_data_key_target. The description only states what it does, with no mention of alternatives, prerequisites, or scenarios where this tool is preferred.

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