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

Annotations already provide readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so the description does not need to restate those. However, it discloses little beyond the basic 'update settings' intent: it does not mention slug-change side effects, whether accessMode='password' changes require a password, how idempotencyKey behaves, or any consequential behavior such as URL changes. The description adds minimal behavioral context beyond the annotations.

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?

The description is one short sentence with no filler or repetition. It is structured well for readability, though the phrase 'an exact' is slightly awkward and the brevity sacrifices useful detail.

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 6-parameter update tool with 0% schema descriptions, the description is too sparse to be complete. Annotations and output schema cover some safety and result aspects, but the agent still lacks enough context about which settings can be updated together, what values are valid, and what happens when updating an exact public page. This is below the minimum viable level for a mutation tool with this parameter count.

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 0%, and the description does not compensate. 'Access and visibility settings' loosely maps to accessMode, isIndexed, and isListedOnProfile, but the description gives no meaning for slug, pageId, or idempotencyKey. An agent cannot determine parameter-specific semantics or constraints from the description alone.

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 states a specific verb ('Update'), a specific resource ('NotePom public page'), and the relevant aspect ('access and visibility settings'). It distinguishes the tool from siblings like publish_page and unpublish_page by focusing on updating settings rather than changing publication state, though it does not name those alternatives explicitly.

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 gives no explicit guidance on when to use this tool versus alternatives such as publish_page, unpublish_page, or disable_listing. Saying 'for an exact NotePom public page' implies the target is an existing page, but there is no clear statement of prerequisites, exclusions, or when another sibling should be preferred.

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