List Default Constraints

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

No annotations are provided, and the description does not disclose behavioral traits such as read-only status, side effects, or permissions. The verb 'list' implicitly suggests a safe read operation, but this is not stated explicitly, resulting in low transparency.

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 sentence that efficiently states the tool's purpose without redundancy. It is front-loaded with the key action and resource.

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 simple listing tool with fully described parameters, the description provides sufficient context. It mentions 'their definitions' hinting at output content. However, it could explicitly note that schema and tableName are optional filters, but this is not essential given the schema coverage.

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?

All three parameters are described in the input schema (100% coverage). The description adds no additional meaning beyond the schema's existing parameter descriptions, so the baseline score of 3 applies.

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 'List all default value constraints and their definitions' clearly specifies the verb 'List' and the resource 'default value constraints'. It is distinct from sibling tool 'list_constraints' which likely covers all constraint types, making this specific to defaults.

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 implies usage when needing to view default constraints but provides no explicit when-to-use or when-not-to-use guidance. No alternatives are mentioned, relying on context from sibling tools.

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