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

Annotations (readOnlyHint=false, destructiveHint=false) already signal that this is a non-destructive mutation, so the bar for added context is present but unmet. The description adds no behavioral detail: it does not disclose that the automation can be resumed, what happens to triggers or history, or whether configuration is preserved. No contradiction with annotations exists, but the description contributes nothing beyond them.

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?

The description is four words with zero wasted text, which is maximally concise. However, it is so minimal that it almost restates the tool name and title, adding little informational value; a brief behavioral clause would make the size appropriate rather than under-specified.

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 a full output schema, documented required parameters, and annotations present, the structured data covers return values, safety profile, and parameter semantics. The remaining gap is behavioral context — what pausing actually does and how it is reversed — which matters for a mutating tool with sibling alternatives like archive_automation and unpause_automation. Minimally adequate but incomplete.

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%, with both parameters documented including provenance ('from list_automations', 'from list_reports or list_clients'), so the schema carries the heavy lifting. The description adds no parameter-level meaning, which is acceptable given full coverage; the baseline of 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?

The description states a specific verb and resource ('Pause an automation'), making the core action unambiguous. It is implicitly distinguished from siblings like unpause_automation and archive_automation by the choice of 'pause', but it does not explicitly explain how pausing differs from archiving or suspending, so it stops short of full sibling differentiation.

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 guidance on when to use this tool versus alternatives such as archive_automation, unpause_automation, or update_automation. No context indicates whether pausing is temporary, how it relates to scheduled runs, or when a user should choose pause over archive. The agent must infer usage purely from the tool name.

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