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

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Delete' implies a destructive operation, the description doesn't mention whether this deletion is permanent, reversible, requires specific permissions, affects dependent resources, or has rate limits. The return value description is minimal ('Status message confirming deletion'), which adds some context but insufficient for a mutation tool.

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 appropriately concise with three clear sections (purpose, args, returns). Each sentence earns its place, though the parameter explanations could be more informative. The structure is front-loaded with the main purpose first.

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 mutation tool with 2 parameters, 0% schema coverage, no annotations, and no output schema, the description is inadequate. It covers the basic purpose and lists parameters but lacks critical information about behavioral traits, usage context, parameter relationships, and detailed return values. The description doesn't compensate for the missing structured information.

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%, so the description must compensate. It lists the two parameters with brief explanations ('database_id: The database ID or label' and 'db_name: The logical database name to delete'), which adds some semantic meaning beyond the bare schema. However, it doesn't clarify the relationship between these two parameters (are both required? which takes precedence?) or provide format examples, leaving significant gaps.

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 states 'Delete a logical database' which provides a clear verb+resource combination, but it doesn't differentiate from sibling tools like 'delete_database' or 'delete_record' (though none exist in the sibling list). The purpose is clear but lacks specificity about what distinguishes this deletion from other deletion operations in the system.

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 provides no guidance on when to use this tool versus alternatives. There's no mention of prerequisites, consequences, or when other deletion tools might be more appropriate. The sibling list includes many other 'delete_' tools, but no differentiation is provided.

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