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

Annotations cover the safety profile (non-destructive, not read-only, not idempotent). The description adds real behavioral context beyond them: scheduled entries remain in the plan, and nothing is written or published while paused. It does not address what happens to in-flight jobs or whether repeated calls error.

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, front-loaded with the action and its effect, then the usage condition. 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?

For a single-parameter state-mutation tool with no output schema and annotations covering the safety profile, the description conveys the essential state semantics and usage trigger. Minor gaps around idempotency and in-flight work are not fatal.

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?

There is one parameter with 100% schema coverage; the schema already documents the site field including the allowed value. The description adds no parameter-level detail, so 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?

States a specific verb ('Pause') and resource ('automatic writing and publishing') scoped to 'this site'. It explicitly names the counterpart tool (resume_autopilot), so an agent can distinguish this from the resume sibling without opening either 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?

Gives a clear situational trigger: 'Use when the customer wants to review before anything else ships.' The reference to resume_autopilot implies the inverse condition, but there is no explicit when-not or prerequisite guidance.

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