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

Annotations already state readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is partly covered. The description adds no context beyond that: it doesn't say whether removal is reversible, what gets updated, or whether existing links to the page are broken or just prevented. For a mutation tool this is thin.

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 short sentence with no wasted words, which is structurally clean. However, it is under-specified rather than genuinely concise — brevity comes at the cost of the information the agent needs, so it earns only a middling score.

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 mutation tool with three required parameters at 0% schema coverage, no output schema, and no usage guidance, a one-line description is inadequate. An agent cannot tell from this alone what scope it must supply or what side effects to expect.

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% for all three required parameters (projectId, siteId, url), and the description mentions none of them. There is no indication of what url refers to (the target page), how it relates to projectId/siteId, or the expected format. The description completely fails to compensate for the coverage gap.

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?

The description conveys the intended outcome — articles will stop linking to a page — which is reasonably interpretable alongside the name. However, it never names the actual resource being manipulated (the internal link target) nor distinguishes this from add_internal_link_target or list_internal_link_targets. It states an effect rather than a clear verb+resource action.

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?

There is no guidance on when to use this tool versus the obvious siblings add_internal_link_target or list_internal_link_targets. It also omits any prerequisites or context about what scope (project/site) is required. No when-to-use or when-not-to-use information at all.

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