List Submission Comments Needing Attention

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

Annotations already indicate read-only and open-world behavior, and the description adds meaningful details: the most-recent-comment rule, unaddressed-by-grading-or-reply criteria, and oldest-unaddressed-first ordering. It does not contradict the annotations.

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?

Three compact sentences front-load the core rule, then the ordering and permission requirements. There is no repetition of the tool name or title and no filler.

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 description explains the semantics, output nature, ordering, and required permissions, which is strong for a read-only triage tool with no output schema. Slightly more detail about pagination or response shape could be added, but the current definition is sufficient for correct 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 description coverage is 100%, so all parameters are already documented. The description does not add parameter-level meaning beyond the schema, which matches the baseline for fully covered schemas.

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 action and resource: list submissions where the most recent comment is from the student and unaddressed. This precisely distinguishes it from sibling tools like list_submissions_awaiting_grading or list_students_needing_attention.

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 description gives clear context for when this tool is relevant — surfacing comments the instructor has likely not seen — and notes the instructor/TA permission requirement. It does not explicitly name alternatives or exclusions, but the intended use case is unambiguous.

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