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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully captured. The description adds the 'published public' scoping constraint, which clarifies the data domain but does not disclose additional behavior such as pagination, result ordering, or locale effects.

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?

The description is a single short sentence, which is concise, but it sacrifices substance for brevity. It front-loads the main scope but fails to include any additional useful detail, making it more under-specified than efficiently structured.

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 and no parameter descriptions, the description must provide enough context for correct invocation, but it only gives a minimal scope statement. It does not explain what a 'case packet' contains, how results are returned, or how this tool differs from the 14 sibling tools, leaving a substantial information gap.

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%, meaning the input schema provides no descriptions for query, limit, or locale. The description does not compensate by explaining any of these parameters, their defaults, or the meaning of locale choices. This leaves the agent with no semantic guidance beyond parameter names.

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 clearly states the action (Search) and the resource scope ('published public case packets'), which is specific enough to distinguish from the broader search_knowledge tool. However, it does not explicitly name any sibling alternatives to reinforce differentiation, so it falls short of a 5.

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 phrase 'Search only published public case packets' implies a scope restriction but provides no explicit when-to-use or when-not-to-use guidance. It does not reference any sibling tools such as search_knowledge or get_case, leaving the agent to infer the tool's niche from its name and title alone.

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