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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is structured. The description contributes the non-obvious side effect (email suppression) but says nothing about permanence, whether the record is recoverable, or behavior when the ID doesn't exist.

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?

One sentence, front-loaded with verb+resource, with the side effect appended rather than buried. Nothing wasted.

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-parameter destructive tool the essentials are present, and annotations plus the uuid pattern carry much of the rest. Still missing for a delete: whether it is permanent, and whether a non-existent ID errors or silently succeeds (relevant given idempotentHint=true).

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 0% for the single parameter; only structural hints (uuid format, strict pattern) convey its nature. The description adds no meaning about saved_search_id — e.g., where to obtain it or whether it must reference a search the caller owns.

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 a specific verb (delete) and resource (one of your saved searches), plus the consequential side effect that its email stops. An agent can distinguish this from get_saved_searches, save_search, and set_search_email without opening any schema.

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 when-to-use or when-not guidance. The sibling set_search_email exists precisely so an agent can stop email without deleting, yet the description never names that alternative or the condition that selects it.

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