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

With destructiveHint=true and readOnlyHint=false already declared, the description still adds substantial context: exactly what is destroyed (the site and any changes made in WordPress admin), the side effect (address is freed), what is preserved (the UiChemy project), and that the action is irreversible and requires user confirmation. This is the kind of detail annotations cannot carry.

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?

Three tightly packed sentences: what happens, what survives, and the safety constraint. The destructive scope is front-loaded and no sentence is filler.

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, no-output-schema mutation, the description covers the destructive scope, irreversibility, the preserved resource, and the confirmation requirement — everything an agent needs before calling it.

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?

The schema has a single required projectId with 0% description coverage, so the description is the only source of meaning — and it only implies projectId selects the project whose site is removed ('a project's site', 'naming the address'). It adds no format, ID-source, or lookup guidance beyond that implication.

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 pair (take offline / delete) on a specific resource (the published WordPress site at the uichemysites.com address), and explicitly scopes out the UiChemy project itself. An agent can distinguish this from uichemy_delete_project and uichemy_publish_site without opening any schema.

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?

Gives a clear precondition for invocation — confirm with the user first, naming the address — and clarifies the condition under which the operation is appropriate by noting the project survives and can be republished (i.e., use this when you want to remove the live site, not the project). It does not explicitly name a sibling alternative such as delete_project, which keeps it below a 5.

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