get_assignment_learner_activity

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

There are no annotations, so the description carries the full burden. It does disclose that the operation is a GET and which parameters go into the path vs. query, implying a read operation, but it does not mention body semantics, required fields, auth expectations, or anything about the response.

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 short, front-loads the intent, and then gives useful forest/placement guidance in one follow-up sentence. A minor clarity issue with 'include values' is acceptable given overall brevity.

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?

The output schema covers return shape and the core path/query split is stated, but the role of body is unexplained and there is no explicit distinction from similar assignment/learner tools. It is enough to start with but requires the client or schema inspection to confirm full call shape.

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 0%, so the description must compensate. It meaningfully maps 'route IDs' to path_params and filtering/pagination/sorting/include values to query, which adds real info. However, it never explains what 'body' is for, and 'include values' is vague, leaving a gap in the 3-parameter contract.

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 states a specific verb and resource ('Get learner activity for an assignment') and gives the exact GET endpoint. It does not explicitly differentiate from siblings like list_assignment_learners or get_assignment, but the resource framing is clear.

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?

There is no guidance on when to use this tool versus sibling tools such as get_assignment or list_assignment_learners. The only direction is where to place path and query values, which is parameter placement rather than use-case guidance.

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