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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the mutation/idempotency profile is covered elsewhere. The description adds nothing about what changes on the page, whether existing monitors are preserved, or what happens on repeated calls. "Show" also mildly suggests a read, which sits awkwardly with readOnlyHint=false, though it is defensible as "display on the page."

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?

A single short sentence is front-loaded and free of padding, which is good, but it is under-specified rather than concise — the brevity comes at the cost of any differentiating or behavioral content.

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 no output schema, the agent still needs to know the effect on the status page and how this differs from the four sibling status-page-monitor tools; neither is provided. For a mutation tool in a dense sibling cluster, the description is too thin to be complete.

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%, so all three parameters (id, monitorId, monitorIds) are documented in the schema; baseline 3 applies. The description's "one or more monitors" hints at the single-vs-array split but does not clarify whether monitorId and monitorIds are mutually exclusive or combinable, leaving the only real semantic gap unaddressed.

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 verb "Show" is a loose match for the actual operation implied by the name and title (adding monitors to a status page's configuration), so the phrasing is somewhat vague. The resource (monitors on a status page) is identifiable, but nothing separates this from siblings such as vs_status_page_monitors_update, vs_status_page_monitors_display, or vs_status_page_monitors_remove.

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 versus the closely related status-page monitor tools (display, update, reorder, remove). The reader must infer usage purely from the tool name and title, with no stated prerequisites or exclusions.

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