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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is fully covered. The description contributes one useful behavioral fact — that only public pages are readable — but says nothing about error behavior, pagination, or content truncation for long pages.

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?

Two short sentences, zero filler, with the purpose and output format front-loaded before the input example. Every clause earns its place.

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 full annotation coverage and no output schema, the description covers purpose, format, scope and input shape adequately. The only meaningful gap is what happens when a path is not a public page.

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 only says 'Site path starting with /', so the description's two real path examples (/guides/chevrolet-tahoe-review-texas/, /cars/toyota-tacoma/) add genuine meaning about depth and structure that the pattern alone does not convey.

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 and resource (return a page) plus the output format (Markdown), and scopes it to public pages. It does not name its sibling search_docs, so the distinction between fetching a known path and searching is left implicit.

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?

Two concrete example paths communicate the expected input shape, which implies 'use this when you already have a path'. There is no explicit guidance on when to prefer search_docs over this tool, nor any note about what happens for non-public or missing paths.

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