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

With no annotations provided, the description carries the full burden. It discloses the behavioral promise (search, compare all experiences, return insights/recommendations) and the partial-match name lookup behavior. But it does not state whether the operation is read-only, what the response structure contains, or constraints like data freshness or rate limits — notable gaps since no annotations backstop the safety profile.

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?

Two tight sentences with zero filler. The core function is front-loaded first, and the key access requirement ('No activity ID needed') follows immediately. Every word earns its place.

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 3-param tool with no output schema and no annotations, the description conveys the core function and the single required input adequately. However, it does not position itself against the five sibling report tools (getABPerformanceReport, getXTPerformanceReport, getAPTPerformanceReport, etc.) or indicate which report types it spans, and the absence of any return-shape hints leaves an agent without an output schema to guess what 'insights and recommendations' look like.

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 100%, so the baseline is 3. The description adds mild value by framing activityName as a search key supporting partial matches ('Search for an activity by name') and by clarifying that no ID parameter is needed. It adds nothing beyond the schema for reportInterval or qaUrl, which are already well documented in the schema.

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 ('Search for an activity by name') plus a concrete output ('performance comparison of all experiences with insights and recommendations'). The phrase 'No activity ID needed - just provide the activity name' partially distinguishes it from ID-keyed report siblings like getABPerformanceReport, but it never explicitly names or contrasts a sibling tool.

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?

'No activity ID needed - just provide the activity name' implies the tool is for name-based lookup, which indirectly signals that alternative ID-required report tools exist among the siblings. However, it never explicitly states when not to use this tool or names the alternatives (e.g., getABPerformanceReport, getXTPerformanceReport), leaving that inference to the agent.

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