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

Annotations already indicate destructiveHint=true and readOnlyHint=false, so the agent knows this is a destructive write operation. However, the description adds no additional behavioral context—it does not mention permanence, required permissions, side effects, or what happens on failure. It adds no value beyond the annotations.

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?

The description is a single, clear sentence with no extraneous words. It is appropriately sized for a simple delete operation and gets straight to the point.

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?

Given the low complexity, good schema coverage, and presence of annotations, the description is minimally viable. It tells the agent what the tool does, but it omits any extra context like irreversibility or team-scope behavior. It is functional but not rich enough for a higher score.

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 100%: both 'id' and 'team_id' have clear descriptions. The tool description adds no parameter-specific information, so it does not compensate beyond the schema. Per rubric, baseline is 3 for high schema coverage.

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 clearly states the action ('Delete') and the specific resource ('content library item'), which distinguishes it from sibling tools like delete_post or delete_workflow. It is not a tautology; it expands the tool name into a meaningful full sentence.

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 gives no guidance on when to use this tool versus alternatives, such as delete_post or update_library_item. It does not mention contexts like team scope, prerequisites, or exclusions, leaving the agent without directional cues.

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