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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. The description adds only the vague 'indexed by Scout' framing and says nothing about pagination, result limits, total counts, or what an unfiltered search returns.

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?

A single front-loaded sentence with zero waste. It is efficient, though arguably under-specified rather than concise given the tool's eight-parameter surface.

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 eight optional parameters, no output schema, and no required arguments, the description should explain what happens when no filters are supplied, how results are paged or ordered, and how this corpus relates to the sibling search endpoints. None of that is present.

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 75% with concrete examples and enumerated topic/source values for query, topic, source and company, so most semantics live in the schema. The description adds nothing for parameters, and limit/offset remain undocumented beyond min/max/default, but the baseline of 3 applies when the schema carries the weight.

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 and resource ('Search telecom industry news'), with the added scope that results come from a corpus 'indexed by Scout.' It does not differentiate from siblings like search_tdocs or search_combined, so an agent cannot tell from the description alone which search corpus to pick.

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 guidance on when to use this tool versus the many sibling search tools (search_tdocs, search_positions, search_combined), and no mention of prerequisites or exclusions. The agent is left to infer usage entirely.

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