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

No annotations provided; description implies read-only behavior via aggregation, but does not explicitly state it does not modify data. It is adequate but could be more transparent.

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 well-structured with a summary line, bullet points of outputs, and an Args section. Every sentence is informative and 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?

Despite no output schema, the description explains key return fields (deltas, top lists, verdict, trend). It is nearly complete but could mention exact output structure.

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?

With 0% schema coverage, the description provides full explanations for all 7 parameters, including defaults and meaning, adding significant value beyond 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 clearly states it reports on sales performance versus the previous period, listing specific metrics like revenue/order deltas, top customers, products, and a verdict. It distinguishes itself from sibling tools like 'confirm_sale_order' or 'create_lead' which are transactional.

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 use for a comprehensive sales overview, but does not explicitly state when not to use it or alternatives. Given no similar sibling report tool, it is clear in its purpose.

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