Get Activity Center

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

The annotations already declare readOnlyHint and idempotentHint, conveying a safe read operation. The description adds that it returns a 'summary', implying aggregated data, but does not disclose any additional behavioral details such as time windows, pagination, or data granularity. No contradiction with annotations.

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 that states the resource, scope, and nature ('summary'). Every word contributes value, with no redundancy or filler.

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 zero-parameter read tool, the description is adequate: it names the resource and clarifies the content ('recent assessment activity across modules'). However, without an output schema, a bit more detail about the shape of the summary (e.g., metrics included) would make it fully complete.

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 tool has zero parameters, and the schema coverage is trivially 100%. With no parameters, a baseline of 4 is appropriate; the description doesn't need to add parameter-specific details.

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 identifies the resource: 'Activity Center summary', with a specific scope: 'recent assessment activity across modules'. The verb 'Get' is specific, and the mention of 'summary' distinguishes it from other info tools like cymulate_info_users_list or cymulate_platform_activity_logs.

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 implies usage for viewing a high-level overview of recent assessment activity, but it does not explicitly state when to prefer this tool over alternatives such as cymulate_platform_activity_logs or cymulate_info_integrations_status. No exclusion criteria are provided.

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