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 tool deletes something, implying a destructive mutation, but doesn't disclose critical behavioral traits like whether deletion is permanent, requires specific permissions, has side effects, or returns confirmation. For a destructive tool with zero annotation coverage, this is a significant gap.

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 a single, efficient sentence with no wasted words. It front-loads the key action ('Delete') and resource, making it immediately clear. Every part of the sentence earns its place by specifying the target.

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 deletion tool with no annotations and no output schema, the description is incomplete. It doesn't cover behavioral aspects (permanence, permissions), usage context, or what to expect after invocation. Given the complexity and risk of deletion operations, more information is needed to guide safe and correct use.

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 tool has 0 parameters with 100% schema description coverage, so the schema fully documents the lack of inputs. The description adds value by specifying that deletion is based on 'AuthN Mapping UUID', implying the UUID might be handled elsewhere (e.g., in the URL or context), which provides useful semantic context beyond the empty schema.

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 action ('Delete') and resource ('an AuthN Mapping specified by AuthN Mapping UUID'), making the purpose specific and understandable. However, it doesn't explicitly differentiate from sibling delete tools (like delete_api_key, delete_user, etc.), which would require mentioning what makes AuthN Mapping deletion distinct.

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., needing the UUID), when not to use it, or what happens after deletion. With many sibling delete tools, context on usage is missing entirely.

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