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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds real behavioral context beyond that: results follow the site's sidebar reading order, are grouped into sections, include titles and paths, and are scoped to one version. It omits pagination or result-size limits, which keeps it from a 5.

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 action and ordering, then routes to alternatives and the follow-up tool. Dense but each clause carries information; the long first sentence is slightly run-on but not wasteful.

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 read-only listing tool with no output schema, the description covers the result shape (grouped sections with titles and paths), scoping (version, section), alternatives, and the next step. Nothing needed to call it correctly 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?

Schema description coverage is 100%, so both parameters are already documented, and the enum for section is structured. The description reinforces version scoping ('The pages are those of `version`') but adds no syntax or semantics the schema lacks; baseline 3 applies.

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 a specific verb (lists) and resource (the FrontMCP docs pages) plus the organizing principle (site sidebar order, reading order) and the content of the result (groups with titles and paths). It is clearly distinguishable from siblings like search_docs, lookup_api, and get_page without opening any schema.

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?

Explicitly gives the use case (browse, or find a page by topic when you don't know its name) and names the faster alternatives (search_docs, lookup_api) for specific lookups, plus the natural follow-up tool (get_page). Both when-to-use and when-to-use-something-else are stated.

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