login_keys_get

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

No annotations are provided, so the description carries the full behavioral burden. It only says 'Get one login key,' which implies a read operation, but it does not disclose what is returned, whether the key secret is exposed, error behavior, or any authentication or permission requirements. For a security-related tool, this is thin.

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 front-loaded, with no filler words. The Args block is redundant with the schema but not bloated. It is concise to the point of being sparse, but for a simple one-parameter getter this is acceptable.

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?

The tool is a simple get operation with one required parameter and an output schema, so the description does not need to explain return values. However, it lacks sibling differentiation and enough parameter context to be fully self-sufficient for an agent navigating a large toolset.

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's 'key_id: Key id' essentially repeats the schema property title without adding format, source, or example information. The agent cannot learn how to find or format the key ID beyond the raw property name.

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 states a specific verb and resource: 'Get one login key.' The word 'one' signals this is a fetch-by-ID operation, distinguishing it from login_keys_list, which presumably returns multiple keys. It is clear, though it does not explicitly name sibling alternatives.

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 siblings such as login_keys_list, login_keys_history, or login_keys_commands. The description only says what it does, not when it should be selected or what prerequisite information (like where to obtain key_id) is needed.

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