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

With no annotations, the description carries the full burden; it does disclose that results are canonical citable URLs, which is real output information. However, it says nothing about whether full guide text is returned, whether an empty result is possible, or any auth/rate considerations.

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 compact sentences with the verb and domain front-loaded and the return-value note second. No filler, though it could have used a few of the saved words to explain the query parameter.

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 search tool with no output schema, the domain scope and return format give an agent enough to attempt a call. The missing query-format guidance and result-set behavior leave a real gap for correct invocation.

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% for the single 'query' parameter, and the description adds no meaning about what a query should contain — keywords, product model names, natural-language questions, or language handling are all unstated. The description must compensate here and does not.

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 resource (public guides) and scopes the domain to Motorola radios, batteries, parts, and CONATEL homologation in Venezuela. That clearly separates it from search_products and search_services, 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?

The topical scoping implies when to reach for it (informational/guide content rather than catalog lookups), but there is no explicit statement about when to use this versus the sibling 'search' or 'fetch_guide', and no exclusions or prerequisites.

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