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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the agent knows this is an irreversible-style mutation. The description adds a genuinely useful scope limitation (published page survives), but omits the things that matter most for a destructive call: whether deletion is permanent, whether related data (keywords, improvements, distribution posts) cascades, and what permissions are needed.

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 short sentences, front-loaded with the action and followed by the scope caveat; nothing is wasted. "from Ranklybee" is the only filler, since the product context is already implied.

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-required-parameter mutation with no output schema and no annotation explanation of side effects, the description should say more. It is silent on permanence, cascade effects, param meaning, and error conditions, so an agent cannot safely reason about the consequences of 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?

Schema description coverage is 0% for all three required parameters, so the description carries the full burden and gives nothing: projectId, siteId and assetId are never mentioned. In particular, assetId is not identified as the article identifier, leaving real ambiguity in a destructive operation.

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 verb and resource ("Delete an article from Ranklybee") and adds a scope clarification: it does not remove a page already published on the website. The resource is unambiguous against the other delete_* siblings (delete_product, delete_lead_keyword, delete_outreach_template), though no sibling is named explicitly.

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 second sentence sets a boundary — deletion here does not unpublish a live page — which hints at when this is and isn't the right operation. However, it never states prerequisites, when to prefer update_article or a publish/unpublish pathway, or whether the article must be in a particular state to be deleted.

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