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

With no annotations, the description carries the full burden and does reasonably well: "Fetch" plus the settings-inspection framing makes the read-only nature clear, and "You can only read your own pages" is a genuine authorization constraint not otherwise encoded. It does not state what happens for a nonexistent, deleted, or restored page (relevant given delete_page/restore_page siblings).

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?

Front-loaded with the core action, then purpose, then parameter guidance; every sentence has a function. The returned-field enumeration is a long comma-separated run that borders on a list dump but is justified because no output schema exists.

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?

Since there is no output schema, spelling out the returned fields is exactly the right compensation, and the ownership restriction plus param identification cover what is needed to call it. Missing only edge-case behavior (page not found, unpublished/trashed pages) for full completeness.

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% and the schema itself explains "the part after the last '/'", so the description's restatement of the `page` parameter (viewer URL or slug) adds no meaning beyond structured data. Baseline 3 applies since the schema does the heavy lifting for the single required param.

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?

Opens with a specific verb+resource ("Fetch the details of a single published page") and then enumerates exactly which attributes come back, so the agent knows precisely what this returns. It is clearly distinguishable from list_pages (many) and update_page (mutation) among the siblings.

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?

Gives concrete usage triggers ("how many views does my page have?" and checking settings "before changing them"), which implicitly routes to update_page for the mutation case. It stops short of explicitly naming update_page or list_pages as alternatives/exclusions, so the routing is inferential rather than declared.

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