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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description adds genuinely new behavior: after removal it "checks the remaining pages against the rules," an undisclosed side effect not visible in annotations. It omits irreversibility and what happens if the path does not exist.

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 sentences, zero filler, with the action and scope front-loaded ahead of the spec link. The OpenAPI URL is a compact way to point at deeper contract detail.

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 destructive three-parameter mutation with no output schema, the description covers purpose and one post-deletion side effect but leaves return values, failure modes, and editKey semantics unexplained. Adequate but with clear gaps.

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 0% — all three required parameters (websiteId, editKey, path) carry only regex patterns and no prose. The description only implicitly maps "one saved file" to path and "a website" to websiteId, and says nothing at all about editKey, which is presumably an authorization credential an agent must understand before calling.

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 ("Removes one saved file") and scopes it to a site created by start_website, which separates it from the sibling delete_website. It does not explicitly say how it differs from delete_website, so it stops just short of full sibling differentiation.

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?

"from a website started with start_website" gives a clear prerequisite and usage context. There are no explicit when-not conditions or named alternatives (e.g., when to use delete_website vs this tool), so it earns a 4 rather than a 5.

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