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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is fully covered. The description usefully adds the return shape (titles, URLs, one-line summaries), but says nothing about result truncation, relevance ranking, or how the limit interacts with what is returned.

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, no padding, with the corpus scope front-loaded and the return format second. Every phrase carries information an agent needs.

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 simple two-parameter read-only search with no output schema, the description covers purpose, domain and return shape, and annotations cover the safety profile. The remaining gap is the undocumented limit parameter and result ordering, which is minor but not nothing.

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 50%: query is described in-schema as "Words to search for", while limit carries only type/default/min/max bounds. The description does not mention limit at all or explain result ordering, so it adds little beyond the schema; a 3 is the baseline for this coverage level.

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 ("Search") and a specific resource scope ("guides, service pages and research on airedteamingservices.com"), plus what comes back. It does not explicitly differentiate itself from the sibling get_page (the obvious follow-up call), which keeps it from 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?

Usage is implied rather than stated: an agent can infer this is the discovery step before get_page, but the description never says 'use this first, then fetch a result with get_page' or when not to use it. No prerequisites or exclusions are given.

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