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. It states the action ('Enroll') which implies a write/mutation operation, but doesn't disclose any behavioral traits such as permissions required, whether it's idempotent, what happens on duplicate enrollment, error conditions, or response format. For a mutation tool with zero annotation coverage, this is a significant gap in 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, efficient sentence that states the core purpose without any wasted words. It's appropriately sized and front-loaded with the essential information. Every word earns its place.

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 incomplete. It doesn't explain what happens after enrollment (e.g., success response, error handling), behavioral implications, or system effects. Given the complexity of user-bundle relationships and the lack of structured metadata, the description should provide more contextual information about the operation.

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 100%, so the schema already documents all four parameters with their types and basic descriptions. The description adds no additional parameter semantics beyond what's in the schema (no format examples, constraints, or relational context). This meets the baseline of 3 when the schema does the heavy lifting.

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') and target ('a user in a bundle'), providing a specific verb+resource combination. It distinguishes from siblings like 'create_enrollment' (which might be more general) and 'update_bundle_enrollment' (which modifies existing enrollments). However, it doesn't explicitly differentiate from 'gql_bundle' or other bundle-related tools, keeping it at a 4 rather than a 5.

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 (e.g., user and bundle must exist), when not to use it (e.g., for existing enrollments), or explicit alternatives like 'update_bundle_enrollment' for modifications. The agent must infer usage from context alone.

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