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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered structurally. The description adds a useful operational note that no human approval is required and lists the state fields surfaced, but says nothing about scoping behavior when service is omitted or any limits on the container list.

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 compact, but the first sentence is a dense comma-list fragment that requires re-reading, and the trailing 'This call asks no human' is sentence-fragmented. Front-loading is acceptable but clarity suffers for the size.

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, the field enumeration is valuable, but two of three parameters remain undocumented and there is no guidance on the all-Services case or output shape per server. For a 3-parameter status tool it is roughly the minimum viable description.

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 coverage is only 33%: only 'service' carries a description ('Omit for every Service here'). The description adds no meaning for 'project' or 'environment' and does not explain that omitting 'service' broadens the query to all Services in scope.

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 indicates a read of a Service's state and its containers per server, and enumerates the returned fields (health, restarts, image, Deployment, latest restart, start/stop). However, the phrasing 'as the canvas shows it' is vague and it never distinguishes itself from close siblings like service_inspect, service_metrics, or server_show.

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 explicit statement of when to use this versus service_inspect or deployment_show. The only usage-adjacent signal is 'This call asks no human', which tells the agent nothing about selecting this tool over its siblings.

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