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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and closed-world scope, so the safety profile is fully covered. The description adds that the response is Markdown and which paths are valid, but says nothing about missing-path behavior, auth requirements, or response size limits.

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 action and return format, then spends the rest of its length on the path list, which is the one piece of information the schema does not supply. Nothing is wasted.

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 no output schema, the description covers the action, the content type, and the valid inputs, and 'as Markdown' characterizes the return. Only absence of error/pagination behavior keeps it from a 5.

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% for the single path parameter, so the baseline is 3. The description genuinely adds meaning beyond the schema by enumerating the valid path families and slug/id patterns, effectively supplying the value set that the schema omits (no enum is defined).

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 ('Read any CutLuma content page as Markdown') and then enumerates the exact route families it serves, which makes the scope concrete. It falls short of a 5 because it never distinguishes itself from siblings that cover adjacent content, such as get_pricing, find_templates, video_size_guide, or list_free_tools.

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?

The route enumeration implicitly tells an agent when this tool applies (fetching marketing/site content by path), but there is no explicit when-to-use, when-not-to-use, or named alternative. With content-specific siblings like get_pricing and find_templates in the list, an explicit routing note would have been valuable.

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