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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses almost nothing: no auth requirements, no rate limits, no result ordering or pagination behavior, no indication of what is returned. The only behavioral signal is the multi-domain scope, which is thin for a search tool with zero annotation coverage.

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?

One short sentence with no filler, and the scope (the three servers) is front-loaded. It is arguably under-specified rather than over-long, but nothing is wasted.

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 tool with no output schema, no annotations, and an undocumented required parameter, the description is too sparse. An agent still lacks basic information about query semantics, result shape, and when to prefer this over the domain-specific siblings.

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% and the single parameter 'q' is undocumented in the schema (only minLength 2 is declared). The description's 'cross-search' hints that q is a query string but adds no syntax, format, or matching-behavior detail, so it does not compensate for the coverage gap.

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 description names a specific verb (cross-search) and enumerates the three resources it spans (news, catalog, RP servers). This implicitly distinguishes it from siblings like search_catalog and list_news, though it never names those alternatives explicitly. Clear enough that an agent can identify what the tool returns.

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 word 'cross-search' implies 'use this when you want everything at once,' and the sibling set (search_catalog, list_news, list_rp) makes the trade-off inferable. But there is no explicit when-to-use or when-not-to-use statement, no guidance on choosing this over the narrower sibling searchers.

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