List CaaS services

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered structurally. The description adds essentially nothing beyond that: it does not say whether results are paginated, whether they are namespace-scoped only, whether the response is eventually consistent, or what the zone parameter implies about reachability.

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?

It is a single short line with no filler, and the read marker is front-loaded. However, its brevity comes from under-specification rather than disciplined editing — there is simply nothing substantive to trim or organize.

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?

There is no output schema and the description never explains what the listed services represent or what fields come back. For a namespaced Kubernetes-style listing tool with two required parameters, the definition leaves the agent without enough context to predict the call's behavior or result.

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 both 'zone' (with example values) and 'namespace' are already fully documented in the schema. The description adds no syntax, format, or constraint detail beyond that, so the baseline 3 for high-coverage schemas 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?

The description is little more than a restatement of the tool name plus the underlying HTTP route: '[READ] OpenAPI: GET /api/v1/namespaces/{namespace}/services'. It gives no independent statement of what a CaaS service is or what scope is listed, and it does nothing to distinguish this tool from siblings like list_caas_pods, list_caas_deployments, or invoke_caas_api.

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?

There is no when-to-use guidance at all — no context for choosing this over invoke_caas_api (generic passthrough) or the other list_caas_* tools. The '[READ]' tag is the only hint about usage, and it merely echoes the readOnlyHint annotation rather than explaining a scenario.

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