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

Annotations already declare destructiveHint=true, readOnlyHint=false, and non-idempotency, so the safety profile is carried structurally. The description adds only the id-sourcing prerequisite and the true/false toggle semantics; it does not explain what pausing actually does to in-flight runs or that the state change persists.

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, front-loaded with the user intent and followed by the prerequisite. No filler, no repetition 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?

The tool is simple (2 required params, both documented, output schema present), so return value explanation is unnecessary and the description covers intent plus the id prerequisite. It could be slightly stronger about the destructive effect of pausing, though annotations already flag that.

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%, and the schema already documents both parameters (including that id comes from list_automations or create_automation). The description reinforces the id source, adding marginal value over the schema but no new syntax or constraint detail.

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 states a specific action (pause or resume an automation) on a named resource, using the user-facing intent ('wants to pause... or turn... back on') rather than restating the tool name. It is clearly distinguishable from siblings like create_automation or list_automations.

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 gives an explicit trigger ('when the user wants to pause... or turn a paused one back on') and names the prerequisite source for the id (list_automations). It does not address edge cases such as already-paused automations or concurrently running executions, but the core when-to-use is clear.

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