get_service_health

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

No annotations are present, so the description carries the transparency burden. The verb 'Get' implies a read operation, but the description does not explicitly state that it has no side effects, nor does it disclose output shape, aggregate size, potential slowness, or failure behavior across all services.

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, front-loaded sentence with no filler. Every part adds meaning, especially the list of covered service categories, making it easy to parse quickly.

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?

For a zero-parameter read-only status check, the description conveys enough for an agent to select the tool correctly. It does not define response formatting, but with no output schema and a simple goal, that is not a significant completeness 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?

The tool accepts zero parameters, so the schema already requires no clarification. The description still adds value by explaining the scope of the request, matching the baseline for a no-parameter tool.

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 names the specific action ('Get') and the resource ('health status of all backend services') and enumerates covered categories (databases, cache, storage, auth, external dependencies). This clearly separates it from single-service sibling tools like get_database_status or get_web_app_status.

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 'all backend services' implies this is the broad health-overview tool, but the description never names sibling alternatives or says when to prefer get_system_health, get_database_status, or get_ec2_health instead. The routing guidance is implied rather than explicit.

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