get_student_activity

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

With no annotations provided, the description carries the full burden. The verb 'Get' implies a read-only operation with no side effects, which is helpful, but it does not disclose other behavioral traits such as authentication requirements, rate limits, output format, or any constraints on date range. The description is adequate but lacks depth.

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, concise sentence that immediately states the action, resource, and scope. There is no redundant language or clutter, making it highly efficient for an agent to parse.

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 simple read-only tool with two well-described parameters and no output schema, the description gives a clear enough purpose. It mentions the 'hourly page view breakdown' which hints at the return shape, though it does not specify the exact format. Given the simplicity, this is nearly complete.

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%, with both course_id and student_id having clear descriptions. The description adds no additional meaning beyond restating what the schema already provides ('for a specific student in a course'). This meets the baseline but does not exceed it.

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 ('Get'), the resource ('hourly page view breakdown'), and the scope ('for a specific student in a course'). It effectively distinguishes itself from siblings like get_course_activity (course-level) and get_student_assignment_data (assignment data) by specifying the exact granularity.

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. It does not mention any prerequisites, limitations, or exclusions. Without such context, an agent might be unsure whether to call this or get_course_activity or get_student_summaries.

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