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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds value beyond that by clarifying the library is 'built-in' (consistent with the closed-world annotation) and by disclosing the shape of results: matching workflows with steps and a starter prompt.

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 sentences, front-loaded with the verb and resource, followed by the return shape. Every clause carries information; nothing is padded or repeated.

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, the description does the work of explaining what comes back (workflows with steps and a starter prompt), which is the key gap an agent would otherwise face. It does not elaborate on matching/ranking behavior or how narrowing via line_of_business interacts with query, but the essentials for correct invocation are 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 description coverage is 100%, so all three parameters (query, line_of_business, limit) are already documented, including the enum-like values for line_of_business and the 1-5 range for limit. The description's example search terms duplicate what the query parameter description already says, adding no new semantic detail. Baseline 3 applies.

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 ('built-in library of benefits and P&C workflows') and enumerates concrete workflow types (renewal comparison, census cleanup, SBC comparison, loss-run summary, quote comparison, COI review). An agent immediately knows what the tool does and what domain it covers; the unrelated siblings (governance/readiness tools) require no further differentiation.

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?

Usage is implied by the description — reach for this when you need a workflow from the built-in library — but there is no explicit when/when-not guidance and no named alternative to route against. Since the sibling tools are unrelated in function, the omission is less damaging, but it remains unstated.

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