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 it correctly indicates this is a mutation operation ('Update'), it doesn't disclose important behavioral traits like permission requirements, whether changes are reversible, what happens to unspecified fields, error handling, or side effects. The description is minimal and lacks crucial operational context.

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 extremely concise - a single sentence with parenthetical examples. Every word earns its place, and the information is front-loaded with the core purpose immediately clear. There's zero wasted verbiage or redundant information.

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 mutation tool with no annotations and no output schema, the description is inadequate. It doesn't explain what the tool returns, what happens on success versus failure, or important behavioral constraints. The combination of a mutation operation with zero annotation coverage demands more comprehensive description than what's provided.

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 schema description coverage is 100%, so the schema already documents all 5 parameters thoroughly. The description mentions three specific use cases ('change expiry date, mark completed, set free trial') that map to three of the parameters, but this adds minimal value beyond what the schema already provides. The baseline of 3 is appropriate given the comprehensive schema documentation.

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 verb ('Update') and resource ('an enrollment'), and provides specific examples of what can be updated ('change expiry date, mark completed, set free trial'). However, it doesn't explicitly differentiate this tool from its sibling 'update_bundle_enrollment', which appears to serve a similar purpose for bundle enrollments specifically.

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 like 'update_bundle_enrollment' or 'create_enrollment'. It doesn't mention prerequisites, error conditions, or any context about when this update operation is appropriate versus creating a new enrollment.

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