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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false. The description adds meaningful context by clarifying that the destructive act rewrites the monitor's baseline to the last observed answers, which explains why it's destructive and irreversible. No mention of auth requirements or what happens to prior baseline history.

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, then the guardrail. No filler or redundancy.

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 mutation tool with annotations covering safety and idempotency, the description is nearly complete. The remaining gap is what the id identifies (monitor vs. change record) and what happens to the previous baseline, but the essentials to call it safely are present.

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?

Only one parameter, id, fully documented in the schema as the resource UUID (100% coverage). The description doesn't clarify whether the id refers to a monitor or a DNS-change record, which leaves a small ambiguity, but the schema does the heavy lifting.

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 (accept) and resource (DNS changes / monitor baseline), and goes beyond the name by explaining what 'accept' actually means: promoting the last observed DNS answers to the new baseline. It doesn't explicitly differentiate from sibling pause_monitor/inspect_monitor, but the DNS-baseline framing is distinct enough.

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 precondition: use only after reviewing that the change is expected. This is real when-to-use guidance. It falls short of naming alternatives (e.g., inspect_monitor to review before accepting), so not a 5.

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