analytics_range_daily

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

Annotations declare readOnlyHint and openWorldHint, which the description does not contradict. The description adds that it returns daily totals but does not elaborate on behavior like pagination or constraints. It provides some context beyond annotations.

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 concise at two sentences plus trigger words, with the primary purpose front-loaded. Every sentence adds useful information, though trigger words could be considered slightly redundant.

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 four parameters and no output schema, the description should explain the optional parameters and return format. It only covers the core purpose; missing details on paymentMethod, account, and the structure of daily totals make it incomplete.

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 0%, and the description does not mention any parameter names, types, or formats. It only references 'date range' without explaining required startDate/endDate or optional paymentMethod/account. The description adds minimal 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 states 'Get daily totals for a date range' which clearly identifies the verb and resource. It is distinct from siblings like analytics_range_categories but does not explicitly differentiate; however, the trigger words help identify usage.

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?

Contains a 'When to use' section and trigger words, providing clear context for when the tool is appropriate. However, it does not mention when not to use or list alternative tools from the sibling group.

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