getAnalyticsOverview

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does disclose the HTTP method (GET), read-only nature, and rate limit – useful safety information. However, it doesn't specify what data the overview includes, error behavior, or pagination, leaving significant gaps for an agent to infer.

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 a single, compact sentence that front-loads the purpose and includes key constraints (rate limit, read-only). It is free of fluff and easy to parse, though it omits param details that could have been added concisely.

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 two optional parameters, no output schema, and no annotations, the description is incomplete. It fails to explain the parameter semantics or what the overview return value contains. An agent cannot confidently call this tool without guessing at parameter meaning, so the definition is under-specified.

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?

The input schema has two optional parameters (to, from) with zero description coverage. The tool description gives no explanation of their meaning, format, or default behavior. An agent has no idea these likely represent a date range, nor how to format them. This is a critical gap since the schema offers no help.

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 fetches a 'delivery overview' – a specific resource with a clear action. It doesn't explicitly contrast with sibling tools like getAnalyticsTimeseries, but the word 'overview' implies aggregate data versus time-series, so the purpose is reasonably distinct.

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 mentions a rate limit and the read-only nature, which are usage constraints, but it does not explicitly state when to prefer this tool over alternatives (e.g., when you need a summary vs. detailed timeseries). It provides some context but no explicit when-to-use or when-not-to-use guidance.

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