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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed world, so safety is covered. The description adds the one thing annotations can't: the return payload is Markdown text. It says nothing about truncation of long pages, 404/error behavior, or whether the page is fetched live or cached.

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 with zero waste, identifying resource and format immediately. It is a sentence fragment rather than structured prose, which keeps it from being maximal for this dimension.

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 one-parameter read tool with full schema coverage, rich annotations and no output schema, the definition supplies what is missing (the Markdown return format). Only edge-case behavior (missing pages, size limits) is absent, which is a minor gap at this complexity.

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 path parameter already carries example paths plus the '/' home-page convention, so the schema carries the whole burden. The description adds no semantics beyond that, which is the expected baseline here.

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?

Names a specific resource (one page of 313automations.com) and the output format (Markdown), which lets an agent distinguish it from list_pages and search_site by cardinality. It never names those siblings explicitly, so differentiation is inferred rather than stated.

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: fetch a page when you have a path. There is no explicit guidance on when to prefer search_site or list_pages instead, nor any note about what happens with an unknown path.

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