get_daily_sales

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

The description claims a read-only retrieval operation, but annotations indicate destructiveHint=true, implying potential modification. This is a clear contradiction. No further behavioral details are provided to resolve this inconsistency.

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?

Single sentence, front-loaded with the core action, no redundant information. Perfectly concise for a simple tool.

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?

The tool is simple, but the description fails to explain what the 'daily sales summary' includes, the return format, or error handling. The annotation contradiction is a major gap that remains unaddressed.

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% (one parameter 'date' described as 'date (date)'). The description adds context about 'daily sales summary' but does not add new meaning beyond the schema. Baseline 3 is appropriate.

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 retrieves a daily sales summary for a specific date, with a clear verb ('retrieves') and resource ('daily sales summary'). It distinguishes from sibling tools like get_pending_orders or get_top_customers.

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 guidance on when to use this tool versus alternatives, no exclusion criteria, and no context about prerequisites or best use cases. The description simply states what it does without usage direction.

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