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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Delete a customer' implies a destructive, irreversible mutation, but the description fails to disclose critical behavioral traits: whether deletion is permanent or soft, what permissions are required, whether related data is cascaded, what happens on success/failure, or any rate limits. This is dangerously inadequate for a destructive operation.

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 maximally concise at three words with zero wasted language. It's front-loaded with the core action and resource. While severely under-specified, what's present earns its place efficiently without redundancy or fluff.

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 mutation tool with no annotations and no output schema, the description is completely inadequate. It fails to address critical context: what 'delete' means operationally, what permissions are needed, what the response contains, error conditions, or relationships to sibling tools. The agent cannot safely or effectively use this tool based on this description alone.

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 100% (the 'id' parameter is fully documented in the schema as 'Customer ID'), so the baseline score is 3. The description adds no parameter information beyond what's already in the schema—it doesn't explain format constraints, validation rules, or provide examples. It meets the minimum viable threshold but adds zero value.

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 'Delete a customer' is a tautology that merely restates the tool name. While it identifies the verb ('Delete') and resource ('customer'), it provides no additional specificity about scope, permanence, or what constitutes a 'customer' in this context. It doesn't differentiate from sibling delete tools like delete_contact or delete_project beyond the resource name.

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 absolutely no guidance about when to use this tool versus alternatives. There's no mention of prerequisites (e.g., customer must exist), consequences, or when to choose this over other customer-related tools like update_customer or get_customer_by_id. The agent receives zero contextual direction.

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