get_usage_insights

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

No annotations provided. Description only lists output contents, no disclosure of authentication, side effects (e.g., rate limits, data freshness), or return format.

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-loads purpose and lists specific insights, no filler. Every word earns its place.

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?

Despite simple schema (1 optional param), no output schema exists. Description omits return structure or how insights are formatted, leaving the agent uncertain about response shape.

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 already documents the single parameter 'days' with description; tool description adds no further detail. High schema coverage (100%) sets baseline at 3.

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?

Description clearly states verb 'Get' and resource 'unique usage insights', listing specific metrics (cost per project, cache savings, etc.). It distinguishes from '/usage' endpoint, indicating unique value.

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?

Implied usage when wanting insights not in /usage, but no explicit when-not-to-use or alternatives relative to sibling tools like get_quota_status.

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