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

The only behavioral claim, 'Read-only,' merely restates the readOnlyHint=true annotation, so it earns no credit. With annotations present the bar is lower, but the description still omits result count behavior, pagination/limit handling, and what happens when no query is supplied.

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 short, front-loaded sentences with the search scope stated first. It is efficient, though the trailing 'Read-only' sentence duplicates the annotation rather than adding information.

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 output schema, three undocumented parameters, and only a safety annotation, the description is too thin. It should at least explain the type filter values, the limit default, and the shape of returned results.

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%, so the description must compensate. It hints that 'keyword' maps to query and its enumeration of 'templates, bundles and licenses' mirrors the type enum, but the limit parameter (1-20) and query length constraint are never explained.

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 (Agent Field Kit templates, bundles and licenses) plus the matching method (by keyword). It is distinguishable from siblings like get_product and search_advisories, though it never explicitly contrasts itself with them.

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?

No when-to-use, when-not-to-use, or alternative tooling is given. The agent must infer that this is for exploratory lookup versus get_product for fetching a known item; nothing in the description helps it choose.

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