get_cache_information

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

No annotations are present, so the description carries the full burden. It gives some behavioral context by listing the types of information returned, but it does not explicitly state that the operation is read-only, or mention any side effects, permissions, or response format. The verb 'get' implies safety, but this is not explicitly disclosed.

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, well-structured sentence that front-loads the main purpose ('Get comprehensive information about the cache status') and concisely lists the key areas of information. There is no unnecessary verbosity.

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?

The tool has no output schema, so the description must convey what the tool returns. It mentions three specific categories (cached specifications, expiration times, performance metrics), which gives a reasonable understanding. However, it does not specify the return format or whether all cache entries are included, leaving some ambiguity. Overall, it is fairly complete for a zero-parameter getter.

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?

The tool has zero parameters, so the description is not required to provide parameter semantics. The baseline for 0 params is 4; the schema coverage is 100% trivially, and the description does not need to compensate for missing parameter documentation.

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 tool's function: 'Get comprehensive information about the cache status' with explicit details on what it includes (cached specifications, expiration times, performance metrics). It is distinct from sibling tools (list_services, get_service_information, get_all_service_information) which all concern services, not cache.

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 description implies the tool is for retrieving cache-related information, but it does not explicitly state when to use it versus alternatives. Sibling tools are service-focused, so the distinction is implicit, but no direct guidance or exclusions are provided.

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