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

With no annotations, the description carries the full behavioral burden. It does disclose the return format (markdown) and that the whole page is returned ('full text'), which implicitly addresses truncation, but it says nothing about auth requirements, error behavior for an unknown path, or whether boilerplate/navigation 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?

A single front-loaded sentence that leads with the return type and the input selector. It is efficient, with only mild overlap between the description's path example and the schema's identical example.

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 elaboration, and the description covers the one input's semantics. The remaining gap is routing context relative to the sibling page tools, which matters more here than for a leaf utility.

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% and only one parameter exists, so the schema already documents 'path' fully. The description's example value ('/how-we-work') reinforces the expected format but adds nothing the schema does not already state.

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 names a specific verb and resource ('The full text of one page of our site as markdown, by its path') and even shows the path format. It does not, however, distinguish this generic page reader from siblings like company, service_area, or case_studies, which likely return the same kind of page content.

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?

There is no when-to-use guidance and no mention of alternatives. An agent cannot tell from the description whether read_page is the general entry point or a fallback when the section-specific siblings (company, service_area, case_studies) do not apply.

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