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 covered. The description adds the sign-in requirement and identifies the source collection for the id, but says nothing about whether the deletion can be undone or what happens on a missing/already-deleted id.

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?

Two short sentences, zero filler, with the core action front-loaded and the precondition trailing. Nothing could be removed without losing information.

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 delete with rich annotations and no output schema, the description covers action, target collection, identifier source, and auth. Only the post-deletion / error behavior is left unstated.

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 0% and the single id parameter has no schema description, so the description must carry it. It does add meaning by stating the id identifies an entry from my_saved_searches, telling the agent where to obtain the value, though it omits type/format expectations.

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 (saved search) and scopes it to the caller's saved searches via my_saved_searches, which separates it from the my_saved_searches listing tool and save_search. It stops short of explicitly naming those siblings, but an agent can still tell it apart from the rest of the toolset.

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?

'Needs sign-in' supplies a precondition, and the delete semantics imply when it applies. However, it never says when to prefer this over alternatives (e.g. remove_saved_listing vs delete_saved_search) or that the operation is irreversible in user-facing terms.

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