enroll_user

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

Annotations indicate destructive and open-world behavior, but the description adds no further behavioral context (e.g., side effects, permission requirements, or idempotency). The description does not exceed what annotations already convey.

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?

Single sentence with clear verb and object. No unnecessary words. Well-structured for quick comprehension.

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?

Despite complete schema and annotations, the description omits what the tool returns (if anything) and does not cover error conditions or duplication behavior. For a destructive mutation, more contextual detail would improve completeness.

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?

Input schema has complete descriptions (100% coverage) for all parameters. The description adds minimal value by mentioning 'specified role', but the schema already defines 'type' enumeration. Baseline score is appropriate.

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 ('Enroll a user in a course') and mentions 'specified role', which aligns with the 'type' parameter. It differentiates from sibling tools like 'remove_enrollment' and 'list_enrollments' by focusing on creation.

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?

No guidance on when to use this tool versus alternatives like 'create_course' (which enrolls creator) or 'update_course' (which modifies settings). No prerequisites or exclusion criteria provided.

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