get_order_statistics

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

With no annotations, the description carries full burden. It mentions the auth requirement (API key) but omits other behavioral traits like data staleness, read-only nature, or rate limits. The coverage is minimal.

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 sentences, each adding value. Could be more concise but no wasted words. Structure is front-loaded with purpose.

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?

No output schema exists, so description must explain returns. It lists the key outputs (total orders, fulfillment rate, average value, trends). Though format details are missing, it covers the main semantics. For a parameterless tool, this is fairly 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?

No parameters exist, so schema coverage is irrelevant. The description adds no parameter info but none is needed. Baseline 4 applies as no value is lost.

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 retrieves order statistics and KPIs, listing specific metrics. It is unambiguous but does not explicitly differentiate from siblings like get_kpi_dashboard. Score 4 for clear purpose with minor lack of distinction.

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 only usage guidance is 'Requires API key'. There is no advice on when to use this tool versus alternatives (e.g., get_kpi_dashboard, get_financial_metrics). The agent receives no context for selection decisions.

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