blazemeter_user

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

With no annotations, the description carries the full burden. It explicitly states the 'read' action reads current user information, indicating a non-mutating operation. It also hints at the default context scope. This provides adequate transparency for a simple read-only tool, though it does not disclose details like authentication or response format (the output schema likely covers that).

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 concise and structured with sections for actions and hints. It contains no fluff, and each line contributes useful information. The opening 'Operations on user information' is slightly redundant with the tool name but 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?

Given the tool's simplicity (2 parameters, output schema present, read-only action), the description is fairly complete. It explains the action and provides a usage hint. It doesn't elaborate on args, but the schema defines it as a dictionary, and the only action 'read' likely doesn't require complex arguments. The output schema covers return values.

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%, so parameters are already described. The description adds value by specifying the valid action value 'read', which the schema does not provide via enums. It also gives a hint about using it with default account/workspace/project, adding context to the 'args' parameter, though it doesn't detail specific args.

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 operates on user information, with a specific 'read' action that reads current user information from BlazeMeter. This is a specific verb+resource, but it does not explicitly distinguish from sibling tools like blazemeter_account or blazemeter_workspaces, so it misses the top score.

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?

The description provides a hint to use the 'read' action for default account, workspace, and project, which gives some usage context. However, it does not explicitly say when to use this tool instead of alternatives, nor does it mention exclusive conditions or alternative tools.

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