Talk status

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

The readOnlyHint annotation already signals a safe read operation, and the description aligns with that. It adds value by enumerating the reported categories (version, region, console summary, service health). It does not disclose details like response format or whether health checks involve latency, but this is acceptable given the annotation coverage.

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 sentences contain all necessary information with no filler. The output scope is front-loaded and the usage hint is a compact second sentence. Every word earns its place.

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 parameterless read-only status tool, the description covers the key outputs and gives a clear first-call hint. Without an output schema, it could specify the exact response shape, but the listed categories are sufficient for a simple health/status tool.

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 input schema is empty and has 100% schema description coverage by default. With zero parameters, the description has no parameter semantics to add. The baseline for a no-parameter tool is 4, and nothing in the description detracts from that.

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 lists concrete outputs: version, region, console summary, and service health, making the resource clear. It distinguishes itself from the sibling list/get/invoke tools as a status overview rather than a data retrieval or action tool. It lacks an explicit verb like 'returns' or 'reports', but the intent is unambiguous.

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?

'A good first call' gives clear contextual guidance about when to use it: as an initial check before other operations. However, it does not explicitly state when not to use it or name alternatives among the siblings. The usage guidance is implied rather than fully specified.

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