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

With no annotations, the description carries the full burden, and it does usefully disclose that listings are informational only and do not execute or pay for anything. However, it omits who can see public listings, whether results are paginated or ranked, and what the response shape looks like, so significant behavioral gaps remain.

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 no filler; the scope of results is front-loaded and the non-executing caveat follows immediately. Every clause earns its place.

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 one-parameter search tool the description is nearly sufficient on scope but silent on both the query parameter and the return format, and there is no output schema to compensate. It is viable but leaves the calling mechanics undocumented.

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 0% for the single 'query' parameter, and the description never mentions searching, matching, or the 80-character limit. Nothing in the prose helps an agent understand what to pass or how the query string is interpreted.

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 ('Find') and enumerates the distinct resource classes it searches: public creator offers, browser tools, and separately labeled external paid APIs. It is clear what comes back, though it does not explicitly contrast itself with the sibling shopscout_source_status.

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?

There is no statement of when to reach for this tool versus the sibling, nor any preconditions or exclusions for using it. The second sentence reads as a behavioral disclaimer rather than usage guidance, so an agent is left to infer the triggering context.

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