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

No annotations are provided, so the description carries the full burden. It states the action ('Delete') and mentions 'smart identifier resolution' for inputs, but fails to disclose critical behavioral traits such as whether deletion is irreversible, requires confirmation, has dependencies, or affects billing. This is a significant gap 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 front-loaded with the core purpose, followed by specific details in a structured format (Args, Returns). Every sentence adds value without redundancy, making it efficient and easy to parse.

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 incomplete. It lacks information on consequences, error conditions, permissions needed, or what the 'Success message' entails. Given the complexity and risk of deletion, more behavioral context is required.

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?

With 0% schema description coverage and only one parameter, the description compensates well by explaining that 'server_identifier' accepts 'server label, hostname, or UUID', adding meaningful context beyond the basic string type in the schema. However, it doesn't detail format constraints or examples.

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 verb ('Delete') and resource ('a bare metal server'), making the purpose unambiguous. It distinguishes from siblings like 'delete' (generic) and 'delete_bare_metal_server' (specific), though it doesn't explicitly contrast with other deletion tools like 'delete_kubernetes_cluster'.

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 guidance is provided on when to use this tool versus alternatives. While sibling tools include other deletion tools (e.g., 'delete_kubernetes_cluster'), the description doesn't specify prerequisites, conditions, or exclusions for use, leaving the agent to infer context.

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