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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed world, so the safety profile is covered. The description adds genuine behavioral context beyond that by scoping the response to metadata and explicitly excluding page content, which is the key trait an agent needs to know before calling it.

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 purpose and its metadata-only scope are front-loaded in the first clause, which is exactly right. The trailing Args block is largely redundant with the schema and could be dropped, but it costs little and the total length is appropriate.

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?

An output schema exists, so return values need no prose, and the annotations fully cover the safety and idempotency profile. With only two required string params, the description's scope note plus parameter list is nearly sufficient; only ID format/source details are missing.

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% for two required parameters, so the description must carry the load. Instead the Args block merely restates the parameter names ('The project ID.', 'The page ID.') with no format, source, or constraint information, adding essentially nothing over the schema's own titles.

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?

Clear specific verb+resource (get a single page by ID) with a useful scope qualifier: 'metadata only; no content'. This distinguishes it from a content-fetching or listing tool, but it never names the relevant siblings (list_pages, update_page, get_asset) so differentiation is left to inference.

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 'metadata only; no content' note implies when this tool is appropriate (single-entity metadata lookup rather than listing or content retrieval), but there is no explicit when-to-use, when-not-to-use, or named alternative. Usage is inferable rather than stated.

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