databases_create_url_attribute

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Create a URL attribute' implies a write/mutation operation but reveals nothing about permissions required, whether this is reversible, what happens on failure, rate limits, or what the tool returns. For a mutation tool with zero annotation coverage, this description provides almost no behavioral context beyond the basic action implied by the name.

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 maximally concise at just three words. While this represents under-specification rather than ideal conciseness, within the scoring framework for this dimension, it earns full points for having zero wasted words and being front-loaded with the core action. Every word ('Create', 'URL', 'attribute') contributes directly to the minimal purpose statement.

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 this is a mutation tool with 6 parameters, no annotations, and no output schema, the description is severely incomplete. It doesn't explain what a URL attribute is, when to use it, what permissions are needed, what happens on success/failure, or how it relates to other database operations. The agent would struggle to use this tool correctly without significant external knowledge about URL attributes in database systems.

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?

The description adds no parameter information beyond what's already in the schema. However, with 100% schema description coverage where all 6 parameters have clear descriptions, the baseline score is 3. The schema adequately documents database_id, collection_id, key, required, default, and array parameters, so the description doesn't need to compensate for schema gaps but also adds no extra value.

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 'Create a URL attribute' is essentially a tautology that restates the tool name 'databases_create_url_attribute'. While it indicates the verb 'create' and resource 'URL attribute', it doesn't specify what a URL attribute is or how it differs from other attribute types like string or email attributes. Compared to siblings like 'databases_create_boolean_attribute' or 'databases_create_email_attribute', this description provides no meaningful differentiation.

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 absolutely no guidance on when to use this tool versus alternatives. It doesn't mention when URL attributes are appropriate versus other attribute types, what prerequisites exist (like needing a database and collection first), or how this relates to sibling tools like 'databases_create_string_attribute' or 'databases_update_url_attribute'. The agent receives no contextual usage information.

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