get_top_clients_by_usage

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

Discloses constraints like max 1-month range for start_at and limit range (1-100). However, no annotations exist, so description should also note idempotency, performance, or side effects; it only covers parameter behavior.

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?

Structure is clean with an Args list. Each parameter is explained briefly. No unnecessary words, though the first line could be more concise.

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 no annotations, the description covers all 5 parameters with constraints. Output exists but not described, though not required. Sufficient for a ranking tool with moderate complexity.

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 has 0% description coverage, but the description provides clear explanations for each parameter (filtering, time format, default limit). Adds value beyond schema structure.

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?

Clearly states the tool gets top clients ranked by bandwidth usage. Distinguishes from siblings like list_clients (general listing) and get_clients_trend (trend analysis).

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 explicit guidance on when to use this tool vs alternatives like list_clients or get_clients_trend. The description only explains parameters but lacks when/not usage context.

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