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

Annotations already cover the safety profile (readOnlyHint, idempotentHint, closed world), so the description's job is to add return-shape context, which it does: output is markdown with navigation and footer removed. It does not address behavior on a nonexistent path (404/error handling), which is the main remaining gap for a fetch tool.

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 tight sentences: the first front-loads what is returned and in what format, the second tells the agent exactly what to supply. No filler or restated field definitions.

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?

With one required parameter, no output schema, and full annotation coverage, the description supplies the missing return-format detail itself. Only the absence of error/not-found behavior keeps it from being fully complete.

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%, so baseline would be 3; the description earns above that by giving concrete example values ('/'), '/about', '/about', '/knowledge', '/events/intercept') that convey the real URL structure and path format beyond the schema's generic 'path starting with /' hint.

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 ('Returns one page of pontis.company as markdown') plus the transformation applied (navigation and footer stripped). It does not, however, distinguish itself from the sibling get_overview, which is never mentioned.

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 instruction to 'Pass its path' with example routes, so an agent can infer this is the fetch-by-URL-path tool. There is no explicit when-to-use versus get_overview guidance or any stated condition/precondition for choosing this tool over the sibling.

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