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

Annotations already cover safety (destructiveHint=false, idempotentHint=true, readOnlyHint=false), so the bar is lower. The description adds real behavioral context beyond them: what is suspended (planner fill, drafting, publishing), that no credits are consumed, and that manual actions remain available — a useful disclosure for a mutation tool. It doesn't mention permissions or whether already-scheduled items are affected.

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?

Four short sentences, zero filler, with the effect stated first and the escape hatch (resume_site) last. Every clause conveys distinct information.

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 an output schema present, return values need no explanation, and the description covers the operational impact thoroughly. Minor gap: it doesn't say whether pausing affects already-queued or in-flight jobs, which matters for a state-changing tool.

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 100% and the single optional site_id already documents the default-to-connection-site behavior. The description references 'the site' at a scope level matching the parameter but adds no format or selection detail, so the baseline 3 is appropriate.

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+resource ('Pause automatic articles for the site') that is unambiguously distinct from siblings like pause-related state changes. An agent immediately knows this halts automation rather than editing content.

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?

Names the counterpart tool explicitly ('Resume with resume_site') so the agent knows the reverse operation exists. Scope guidance is present ('While paused nothing runs on its own... Manual actions still work'), though it never states the trigger condition such as a user asking to stop automation or avoid credit spend.

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