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

No annotations are supplied, so the description carries the full burden. It does disclose useful behavior beyond the schema: results are ranked, compact, and include prices and links. It says nothing about how ranking works, what 'verified' means operationally, whether calls need auth or are rate-limited, or how paging/limit behaves.

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 tight sentences with zero filler; the primary action and scope come first, the return shape second. Nothing needs trimming and nothing is buried.

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?

With no annotations, no output schema, and two of three parameters undocumented, the description should do more for a search entry-point tool. It omits defaults, category vocabulary, result count behavior, and how the shortlist is ranked, leaving real gaps an agent must guess around.

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 33%: only 'query' is documented (with examples), while 'limit' and 'category' have no description at all. The description adds no parameter meaning — no default for limit, no hint at valid category values (0 enums) or whether query and category combine or override each other.

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 (the Home Generator HQ verified catalog of generators), and adds the result shape (ranked shortlist with prices and links). It is distinguishable from compare_generators and get_generator, though it never explicitly names those siblings.

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 only implied: an agent can infer this is the discovery/entry point when looking for generators by keyword or category. There is no explicit when-to-use, when-not-to-use, or pointer to siblings like get_generator for details or compare_generators for head-to-head comparison.

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