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

Annotations already declare destructiveHint=true and idempotentHint=false, but the description adds substantial context: the deletion happens without a confirmation step, it is recorded, the search is verifiably gone afterward, it requires the settings:write permission scope, and it triggers a sign-in flow if the member has not connected yet. Some sentences ('Private to your member and saved again in one step') are opaque, which keeps it from a 5.

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 purpose is front-loaded in sentence one, which is good. But the paragraph is bloated with fragmentary and hard-to-parse phrasing, and the trailing prompt-injection boilerplate about member-written text is generic rather than specific to this tool.

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 with no output schema, the definition covers the important ground: permission requirement, no-confirmation behavior, audit recording, sign-in prerequisite, and the post-condition. Only the absence of alternative-routing guidance leaves a small gap.

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 100% and the single 'id' parameter is already documented in the schema with a pointer to GET /me/saved-searches. The description adds nothing about the id argument, so it sits at the baseline where the schema does the work.

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 first sentence names a specific verb+resource pair (delete a saved search) that is unmistakable, and the title reinforces it. It does not explicitly name or distinguish the adjacent siblings (edit_saved_search, list_my_saved_searches, save_search, set_saved_search_alerts), so it stops short of a 5.

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 phrase 'The Saved Searches page's Delete on one search' anchors the tool to a concrete UI action, which implies when to reach for it. However, there is no explicit when-not guidance and no named alternative (e.g., use edit_saved_search to modify rather than remove, list_my_saved_searches to find the id).

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