get_attendance_analytics

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

With no annotations provided, the description carries the full burden. It discloses the comprehensive scope ('all sessions with all check-ins') but does not elaborate on side effects, permissions, or potential performance implications. The read-only nature is implied by 'get' but not explicitly affirmed.

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 compact: two sentences plus an Args block. The first sentence front-loads the core purpose and scope, the second gives a use case, and the Args block provides actionable parameter guidance. Every sentence adds value without redundancy.

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 tool is simple (one parameter) and has an output schema, so the description need not spell out return structure. It fully captures the purpose, the scope of data included, and how to obtain the required parameter. It is complete for correct selection and invocation.

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 itself only says course_id is an integer with no description. The tool description adds meaningful guidance: it clarifies what the parameter represents and directs the user to list_courses to find it. For a single parameter, this compensates well for the 0% schema coverage.

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') and the resource ('a combined attendance report for a course — all sessions with all check-ins'). It distinguishes this tool from siblings like list_attendance_sessions and list_check_ins by emphasizing the combined nature, and mentions its utility for summaries.

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 phrase 'Useful for generating attendance summaries' provides a clear context for when to use this tool. However, it does not explicitly state when not to use it or name alternative tools, so it falls short of full explicit guidance.

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