get_index_schedule

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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered structurally. The description adds no behavioral context beyond that — no mention of pagination, term-scoping behavior, or what happens when an index has no sessions.

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?

A single efficient sentence with the object of the operation front-loaded, no filler. Its brevity is appropriate to the sentence itself, though it leaves the tool under-specified rather than genuinely 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?

An output schema exists, so return values need not be described. However, for a tool with four required, undocumented parameters and no usage framing, the description is too thin to let an agent call it confidently versus its five schedule-related siblings.

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?

All four parameters (course_code, index, academic_year, semester) are required with 0% schema description coverage, so the description carries the full burden — yet it only obliquely references 'course index'. It adds no format, range, or interpretation guidance for semester, academic_year, or the index value.

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 every scheduled session') scoped to 'one course index', so an agent can tell it retrieves schedule data rather than course metadata or index lists. It does not distinguish itself from siblings like get_graduate_course_schedule or get_undergraduate_exam_schedule, which cover overlapping schedule territory.

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 explicit when-to-use, when-not-to-use, or alternative tool named. The phrase 'for one course index' only weakly implies you must already have an index (presumably from get_course_indexes); nothing tells the agent how this differs from the other schedule tools.

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