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

The description claims 'Retrieves' (read operation), but annotations set destructiveHint=true, indicating a potential side effect. This is a contradiction, as the description misleads about the tool's safety. No additional behavioral context (e.g., what gets destroyed, auth needs, rate limits) is provided, and annotations are not leveraged to clarify the destructiveness.

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 very short (one sentence) and front-loaded with the core action. However, it omits critical details (e.g., destructiveness, what the summary contains), making it under-informative. It earns its place structurally but lacks substance.

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 only one parameter, high schema coverage, and no output schema, the description should provide richer context about the return format, the nature of the 'daily sales summary', and the destructive hint. It is incomplete for an agent to understand tool behavior fully.

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 coverage is 100%, and the schema already describes the 'date' parameter as 'date (date)'. The description adds no extra meaning or constraints beyond the schema, so it does not improve parameter understanding. Baseline score for high coverage.

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 action ('Retrieves'), the resource ('daily sales summary'), and the condition ('for a specific date'). It is specific and not a tautology. However, it does not differentiate from sibling tools like 'get_pending_orders' or 'get_top_customers', which limits clarity for an agent selecting among them.

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?

There is no guidance on when to use this tool versus alternatives, no mention of prerequisites (e.g., date format), and no exclusion criteria. The description only implies usage via the date parameter, which is insufficient for an agent deciding between multiple sales-related tools.

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