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

Annotations already declare readOnly=false and destructive=false; the description adds that reports are generated and delivered automatically, which is useful context about side effects. However, it does not disclose other behavioral traits such as validation behavior, prerequisites, or failure scenarios.

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 well-structured sentence that immediately states the purpose. Every word contributes meaning, 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?

Given the tool's 6 parameters, 3 enums, and no output schema, the description is minimally adequate. It does not explain what the tool returns (e.g., an ID for the created schedule) or what happens after creation, but the schema covers parameter semantics sufficiently.

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 descriptions provide 100% coverage of all six parameters, so the description does not need to add parameter-level detail. It provides only general context about recurrence and delivery, which goes beyond the schema but does not materially enhance parameter understanding.

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 tool creates a recurring analytics report with automatic delivery, using a specific verb (create) and resource (scheduled report). It emphasizes 'recurring' and 'delivered automatically', which distinguishes it from one-time report tools like run_analytics_report.

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 when to use this tool (when a recurring, automated report is needed) but does not explicitly contrast with alternatives or state exclusions. It lacks guidance on choosing between this and run_analytics_report or scheduling workflows.

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