direct_attendance_record

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 communicates that this is an insert/mutation operation, but it does not mention possible side effects, duplicate handling, permissions, default behavior beyond what the schema already covers, or what happens after a successful insert.

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 one short sentence that immediately states the action and target. There is no filler, and the core purpose is front-loaded. For a simple insert tool, this is appropriately concise.

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 has five parameters, no annotations, and no output schema, so the description needs to supply more operational context. It omits return behavior, duplicate-record behavior, status-category semantics, and when to prefer sibling tools, leaving the agent without enough information to confidently invoke it in context.

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 60%, with status, minutes_late, and minutes_early already described in the schema. The description adds only broad context about a student and a lesson, which is marginal beyond the parameter names. It does not meaningfully explain the undocumented student_id and lesson_id semantics, so it fails to fully compensate for the coverage gap.

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 uses a specific verb ('Insert') and names the resource ('attendance record') with the target context ('for a student in a lesson'). It is clear about what the tool does, though it does not explicitly call out how it differs from sibling tools like attendance_insert_passage or direct_attendance_future_excuse.

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 alternatives such as direct_attendance_future_excuse, direct_attendance_current_excuse, or attendance_insert_passage. The description states the action but provides no context for selection, no exclusions, and no conditions of use.

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