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

Annotations already carry destructiveHint=true, readOnlyHint=false, and idempotentHint=true, so the description does not need to restate those. It adds the authorization scope 'you own' and pricing context, but does not expand on what destruction entails or error behavior. No contradiction with annotations.

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 core action is expressed in a short, front-loaded phrase, and the pricing/ownership details are compact. The 'UNDERSTANDING —' prefix and 'B1 (single-entity synthesis)' jargon add minor noise, but the description remains fast 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 one-required-parameter destructive idempotent operation, the description plus annotations cover safety and ownership. Still, it omits how to retrieve the saved search id and what the result of a successful deletion looks like, so an agent must infer these from sibling tool names or error handling.

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 coverage is only 50%: the required 'id' parameter has no schema descriptionable text, and the tool description does not explain where the id comes from or what format it takes. Since the schema already documents the optional context parameter, the description adds no semantic value for parameters over the 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?

States the specific verb 'Delete', the resource 'saved search', and the ownership constraint 'you own'. This clearly distinguishes it from siblings like delete_list, save_search, and run_saved_search without requiring schema inspection.

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?

Provides a key precondition: only saved searches you own can be deleted. However, it does not explicitly guide the agent on when to choose this over alternatives or how to obtain the id, such as via list_saved_searches. Usage is implied from the tool name and ownership phrase rather than fully specified.

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