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

The destructiveHint annotation only flags that mutation occurs; the description adds substantive context: the operation is a resume, the supplied fields restore CI/CD and autoscaling state, and it names the underlying endpoint. It does not spell out permission requirements or side effects on dependent resources, so it stops short of a 5.

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 sentences, mutation flag front-loaded, endpoint last. No filler or redundant restatement of the title.

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 description is not obliged to explain return values, and it covers mutation semantics and optional restore behavior. Missing only the practical caveats (permissions, effect on running workloads) that would make it fully self-sufficient for an agent.

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 each of the six parameters is already documented. The description only summarizes that instance count and CI/CD/autoscaling state can be restored, adding framing but no per-parameter detail beyond the schema. Baseline 3 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?

States a specific verb and resource ('resume a paused service') and prefixes it with 'MUTATING' to flag the operation class. An agent can distinguish this from sibling northflank_pause_service without opening the schema.

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?

It implies usage by specifying that the service must be paused, but offers no explicit when-to-use guidance versus siblings like northflank_restart_service or northflank_scale_service, which also affect running state. Some inference is required to avoid routing errors.

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