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

The annotations already declare this is a non-destructive, idempotent, open-world mutation, so the safety profile is covered. The description adds no behavioural context beyond purpose, though it does implicitly communicate that the change is a settings mutation affecting a live page. No auth or partial-update semantics are disclosed.

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 front-loaded sentence with a colon-delimited list; no filler or redundancy. The list is slightly long but each item maps to a real configuration area.

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 11 optional parameters, no required fields, and an output schema present, the description omits the one fact an agent most needs for correct invocation: whether unspecified settings are preserved or reset. Otherwise the enumeration plus full schema coverage is adequate, but the partial-update semantics gap is material for a tool like this.

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% and the individual property descriptions are rich (the streamAlertOn enum carries its own cautionary guidance). The description only gestures at the same fields at a summary level, adding no new semantics, 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 and resource ('Change what the page does') and then enumerates the exact behavioural settings it governs: auto-publishing, anonymity, public display, suggested amounts, and the post-payment note. This enumerations lets an agent separate it from siblings like update_page_appearance, update_seo, and update_profile without opening any 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?

The description says nothing about when to call this versus the other page-mutation tools, nor about prerequisites or the fact that all 11 parameters are optional. An agent must infer from the field list alone that this is the tool for behavioural configuration.

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