get_grades

Retrieve your grades for a course, including each graded item's score, maximum, percentage, weight, and feedback.

Instructions

Show your grades in a course.

Use the id from list_courses. Returns each graded item with your grade, the max, the percentage, the weight and feedback (only YOUR grades).

NameRequiredDescriptionDefault
course_idYes
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It explains the return format (grade, max, percentage, weight, feedback) and emphasizes 'only YOUR grades,' but it does not explicitly state that the operation is read-only or discuss permissions, rate limits, or side effects. Adequate but not comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise, consisting of two sentences with no extraneous information. Every word serves a purpose, and the key information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one parameter, no output schema), the description adequately covers the return fields and scope. It could be more explicit about 'current user' and 'all graded items,' but it is largely complete for an AI agent's needs.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description adds meaningful guidance by specifying that course_id should come from list_courses. This clarifies the parameter's origin and usage beyond the schema's type definition.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool shows grades for a specific course, using 'your grades' to distinguish from siblings like get_submission_status or list_assignments. It specifies the resource and action effectively.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context by instructing to use the id from list_courses, but it does not explicitly mention when not to use this tool or provide alternatives. It sets expectations for usage without exclusions.

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