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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, so the safety and determinism profile is fully covered. The description's only added behavior is the content taxonomy of what guides exist, with nothing about count, pagination, or what a returned entry looks like.

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 sentence that front-loads the defining characteristic ('the pages that aren't about one component') before the topic enumeration. The long list of topics is information-dense but borders on padding for a listing tool.

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?

No output schema, zero parameters, and annotations covering the safety profile, so the description's job is mainly to define scope, which it does well by enumerating the guide categories. It could note that it returns a flat list of pages, but nothing essential for correct invocation is 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?

The tool takes no parameters (parameter count 0, 100% schema coverage), so the description carries no parameter burden. Baseline for a zero-parameter tool is 4.

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 identifies the resource precisely as the non-component doc pages (guides), and the enumerated topics make the scope unmistakable. It doesn't name a verb like 'list' nor explicitly contrast with siblings such as get_page or search_docs, so it falls short of 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?

Usage is implied by the contrast 'the pages that aren't about one component' and the 0-param, no-argument shape, which signals a browse-everything-index tool. However, there is no explicit when-to-use statement or routing rule pointing to search_docs or get_page for other needs.

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