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

Annotations correctly indicate this is a non-destructive write operation (readOnlyHint=false, destructiveHint=false). The description adds valuable behavioral context that it 'Updates memberships if already member of a class,' clarifying conflict handling. However, it lacks details on authentication requirements, rate limits, or what fields get updated when memberships already exist.

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?

Two sentences with zero waste: first states the primary action, second clarifies the upsert-like behavior with existing members. Information is front-loaded and appropriately scoped for a focused utility tool.

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?

Adequate for a 4-parameter mutation tool with good schema coverage. Missing information on return values (success confirmation, affected records), error handling (invalid class/user IDs), and whether the operation is atomic (all-or-nothing) or partial.

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 100% description coverage, documenting comma-separated formats, date formats, and default values. The description adds no parameter-specific semantics beyond what's in the schema, meeting the baseline for high-coverage schemas.

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 tool assigns users to classes with specific verbs ('Assign', 'Updates'). However, it does not distinguish from the sibling tool 'edubase_post_class_members' (singular), which likely handles single-class assignments versus this tool's comma-separated batch capability.

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 'edubase_post_user_classes' (which likely assigns classes to users from the user perspective) or 'edubase_post_class_members' (singular). The description mentions handling of existing memberships but doesn't frame it as a selection criterion.

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