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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description adds one genuinely useful piece of context beyond that — 'It stops being checked' tells the agent the monitoring consequence — but says nothing about whether historical captures are lost or whether the action can be undone.

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 action; the second sentence about monitoring cessation earns its place. No filler or repetition.

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 two-parameter destructive delete with no output schema, the description plus annotations give an agent enough to act: what is removed, and the effect on checking. Only the recoverability/history question is unresolved, which is a minor gap against rich annotations.

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 required params ('Monitor id' and 'Extra page id') documented in the schema itself. The description adds no further clarification about id format, scoping, or what happens if the id pair mismatches, so the baseline 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 (delete) and resource (an extra page of a visual monitor), which distinguishes it clearly from vs_subpages_add/list/update/capture_now. It uses 'extra page' rather than the schema's 'subPageId' vocabulary, but the title and params make the mapping obvious.

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 delete a subpage versus updating it, no prerequisite or permission notes, and no mention of siblings such as vs_subpages_list for confirming the id first. Usage is only implied by the verb.

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