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

The annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds one genuinely useful behavioral fact beyond them — the response payload is Markdown rather than structured data — but says nothing about how a nonexistent path is handled or whether full page content or metadata is included.

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, front-loaded with the essential fact (Markdown by path), and the examples each earn their place by illustrating a distinct path shape. It reads as a fragment rather than a complete sentence, which slightly undercuts clarity but wastes no words.

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 single-parameter read tool with no output schema, the essentials are present: what it returns, how to address it, and what the path looks like. Missing are only edge-case behaviors (invalid path, empty page, pagination/truncation of long pages), which are minor at this complexity.

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%, so the description must carry the parameter semantics, and it does: it names the parameter's meaning (page path) and supplies four concrete path shapes including the leading slash and the '/' home convention. It stops short of stating whether the path requires the leading slash or whether a trailing slash matters.

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 the resource (a page), the access key (path), and the return format (Markdown) in a single front-loaded phrase, which already separates it from list_pages. It never spells out the verb ('return/fetch'), relying on the tool name, so it falls short of the crisp verb+resource clarity of a 5.

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 when-to-use guidance and never mentions its siblings: it doesn't say to call list_pages first to discover valid paths, or to prefer search when the path is unknown. Usage is only inferable from the name and the examples.

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