focus_create_client

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It fails to mention side effects (e.g., permanent creation), required permissions, or potential errors. The word 'immediately' hints at synchronous behavior but is too vague to be informative.

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 extremely concise and front-loaded, with the core action in the first phrase. The 'Toggl Focus/2.0' prefix provides product context. However, it is so brief that it borders on under-specification, but for a simple tool it is acceptably short.

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 has 4 parameters, no output schema, and no annotations, the description should explain return values, error cases, or behavioral nuances. It does none of this. For a create operation, an agent would not know what to expect after invocation.

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 75%, leaving the 'name' parameter without a description, but the description adds nothing beyond the schema. It repeats the requirement of 'name' (already in the schema) and does not explain currency, workspace_id, or organization_id behavior or defaults.

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 ('create a client') and the resource ('client'), which is a specific verb+resource combination. It does not explicitly differentiate from sibling tools like create_project or create_task, but the resource type itself provides clear distinction.

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 offers no guidance on when to use this tool versus alternatives. It only states 'Requires name,' which is a prerequisite, not a usage scenario. There is no mention of when to choose create_client over list_clients or other create tools.

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