get_class_day

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

There are no annotations provided, so the description carries the full burden of behavioral disclosure. It only states 'Get a class day schedule' with no information about side effects, read-only nature, authentication requirements, error conditions, or return format. This provides no transparency beyond the bare action.

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 directly states the tool's purpose without any fluff or repetition. It is appropriately sized for a simple get operation and front-loads the key action, making it easy to scan.

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?

Given the complexity of 4 required parameters and no output schema, the description is severely incomplete. It fails to explain what constitutes a valid date format, how the schedule is structured, what the return value looks like, or any edge cases. There is no distinction between school days and holidays, and no indication of whether multiple classes share schedules. This is far below the minimum viable for reliable 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?

Schema coverage is 0%, meaning neither the schema nor the description explains the parameters. The description does not add any meaning to 'date', 'grade', 'class_no', or 'school_code' beyond their names. Without descriptions or examples, an agent cannot know expected value formats, date patterns, or how to construct valid requests.

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 'Get a class day schedule' uses a specific verb (get) and resource (class day schedule), clearly distinguishing it from sibling tools like get_class_week (week vs day) and get_teacher_day (teacher vs class). The scope is explicit: it returns a schedule for a specific class on a specific day.

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 explicit guidance is provided on when to use this tool versus alternatives like get_class_week or get_teacher_day. However, the tool name and sibling names imply that this is for day-level class schedules, making usage context inferable but not stated. There is no mention of exclusions or alternative selection criteria.

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