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 effectively communicates the irreversible nature of the action ('This action cannot be undone'), which is critical for a destructive operation. However, it lacks details on permissions, error conditions, or what happens to associated resources, leaving some behavioral aspects unclear.

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 extremely concise and front-loaded, consisting of just two sentences that directly state the action and its critical consequence. Every word serves a purpose, with no redundant or vague phrasing, making it efficient for quick comprehension.

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?

For a destructive tool with no annotations and no output schema, the description is minimally adequate. It covers the irreversible nature but misses important context like required permissions, success/error responses, or system state changes. Given the tool's potential impact, more completeness would be beneficial despite the concise structure.

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 100% description coverage, with the 'id' parameter fully documented in the schema itself. The description adds no additional parameter semantics beyond implying deletion targets a usage limit by ID, which is already covered by the schema. This meets the baseline for high schema 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 specific action ('Delete') and resource ('a usage limit by ID'), making the purpose unambiguous. It distinguishes itself from sibling tools like 'get_usage_limit' or 'update_usage_limit' by focusing on deletion rather than retrieval or modification.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., whether the usage limit must exist or be inactive), compare it to similar tools like 'delete_rate_limit', or specify conditions for successful deletion. The absence of usage context leaves the agent without decision-making criteria.

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