create_business_activity

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

Annotations indicate this is a mutating, non-idempotent operation, but the description adds no behavioral details beyond that. It does not mention side effects, required fields, permissions, failure modes, or return values. Since the description contributes nothing beyond the structured fields, it fails to disclose any additional behavioral traits.

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 short, but this is under-specification rather than effective conciseness. The single sentence 'Create business activity' merely repeats the tool name and does not earn its place by adding any useful information. It lacks the substance required to be considered well-structured.

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 a create operation with four parameters, no output schema, and minimal annotations, the description is severely incomplete. It offers no context about what data is needed, how the operation behaves, or what the result will be. The agent is left without sufficient information to use the tool correctly, especially with low schema coverage.

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 only 25% (only account_id has a description). The tool description does not mention any parameters, so it does not compensate for the missing schema documentation. With three out of four parameters entirely unexplained, the agent cannot infer their semantics from the description.

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 'Create business activity' is a direct restatement of the tool name. It provides no additional details about what a 'business activity' is or any distinguishing scope beyond the name itself. The verb and resource are present but tautological, offering no new information to differentiate from other create_* tools.

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 zero guidance on when to use this tool versus alternatives. Sibling tools like list_business_activities and search_business_activities exist, but no comparison or selection criteria are provided. The description does not mislead, but it also gives no situational context or prerequisites.

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