list_peer_reviews

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

With readOnlyHint=true, the annotation already covers the safety profile. The description adds that it lists 'all' peer review assignments, implying a comprehensive result set, but does not disclose pagination, ordering, or response structure. This adds minimal context beyond the annotation, meriting a mid-range score.

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 clear sentence with no redundant information. Every word contributes to the meaning, making it exceptionally concise and well-structured.

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 absence of an output schema, the description could have elaborated on the return format or clarified the distinction from similar sibling tools. The description is functionally adequate but leaves some ambiguity in a rich context of peer-review tools, so it falls short of being fully complete.

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?

The input schema provides 100% coverage with descriptions for both parameters ('Canvas assignment ID' and 'Course code or Canvas ID'). The description does not add additional meaning beyond what the schema already states, so the baseline score of 3 is appropriate.

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 clearly states the action ('List') and the resource ('peer review assignments') with a scope ('for a specific assignment'). It effectively conveys what the tool does, though it does not explicitly distinguish it from similar sibling tools like 'get_peer_review_assignments' or 'get_my_peer_reviews_todo'.

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 provides no guidance on when to use this tool versus the many peer-review-related siblings. There is no mention of alternatives, prerequisites, or scenarios where this tool is preferred. The intended usage is only implied by the action itself.

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