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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is carried by structured data; the description correctly implies idempotent boolean setting. What it omits is the destructive consequence: what happens to display flags not passed in, and whether existing per-monitor customizations are overwritten when monitorIds is omitted. For a destructive bulk write that is a meaningful gap.

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?

One sentence, zero filler, with the settable displays and the scope choice front-loaded. Nothing is repeated and nothing is padding.

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 5-parameter bulk mutation with no output schema, the description covers what is toggled and the two scope modes, and annotations cover the destructive/idempotent profile. The remaining omission, partial-update semantics when only some flags are provided, is modest rather than crippling.

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%, so all five parameters are already documented. The description's enumeration of graph/response time/certificate roughly mirrors showGraph/showResponseTime/showSSL without adding format or default semantics, and 'only the listed ones' simply restates monitorIds' own schema text. 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?

The description names a specific verb ('turn ... on or off') and a specific resource (graph, response time, or certificate display for monitors on a status page). It is clear what changes and at what scope. It does not, however, name the sibling that handles per-monitor display edits (vs_status_page_monitors_update) versus this bulk variant.

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?

The phrase 'for every monitor on a status page, or only the listed ones' implicitly tells the agent this is the bulk operation and how to narrow scope. There is no explicit statement of when to prefer it over vs_status_page_monitors_update, vs_status_page_monitors_add, or vs_monitors_update_visual, and no prerequisites are given.

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