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

The annotations already declare destructiveHint=true and readOnlyHint=false, so the destructive nature is covered by structured data. The description adds value by disclosing the authorization requirement, but omits other behaviorally significant details: whether the delete is recoverable, what happens if the id/path does not exist, and whether nested documents are removed. It also states that the 'comment' role can delete, which is unusual and may mislead if the backed behavior differs.

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 tight sentences with the action front-loaded and the prerequisite second. Nothing is wasted, though the terse phrasing of the role requirement ('owner, edit or comment role') is slightly ambiguous.

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 two-parameter mutation with no output schema and no documented parameters, the description leaves core questions unanswered: what exactly 'id' and 'path' identify, what the return looks like, and what happens on missing documents. The permission note is the only substantive addition beyond the annotations.

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 the two required parameters: 'id' and 'path' are bare strings with no explanation. The description does not clarify whether 'id' is the artifact id and whether 'path' is a document key or a hierarchical path, nor whether must the document already be present. With zero schema coverage, the description needed to compensate and does not.

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 uses a specific verb+resource: 'Delete one document of the artifact's shared database'. It is clearly distinguishable from siblings such as db_get, db_set, and db_query by virtue of the delete action, though it never names those siblings.

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 description adds the permission prerequisite ('needs the owner, edit or comment role'), which is genuine context for deciding when the call will succeed. It gives no explicit guidance on when to use this tool versus db_set (e.g. clearing a key) or when not to delete, so the usage guidance is implied rather than stated.

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