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

Discloses that it is read-only analytics and mentions grouping by day (categorize_by=TIME). This goes beyond the readOnly annotation by explaining the grouping behavior, but still lacks details on potential failures or edge cases.

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 two short, focused paragraphs with no filler. Every sentence conveys essential information about the tool's function and constraints.

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?

Covers the purpose and a key constraint (window length) but lacks explanation of parameter semantics and output structure. Since no output schema is provided, the description could be more complete about what the trend data looks 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?

Only the 'query' parameter has a description (from the schema). The description does not explain how to specify the time window using start_time, end_time, start_days_ago, or end_days_ago, leaving most parameters completely undocumented.

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?

Clearly states the tool retrieves daily cyber-security incident trends over time, and distinguishes from siblings by specifying 'daily' and 'over time'. The read-only analytics note reinforces its purpose.

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?

Provides a specific usage constraint: the window must be 7- or 14-day historical interval. This implies when to use (for spotting spikes) but does not explicitly contrast with alternatives like by-location or by-threat variants.

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