pup_list_students

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

The readOnlyHint annotation already communicates that this is a safe read operation, lowering the burden on the description. The description adds useful outcome context (each student's plan and review state) but does not disclose ordering, pagination, or other runtime behavior. No contradiction with 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?

One compact sentence conveys scope and content with no filler. The key idea, 'every student on the account,' is front-loaded, and every phrase earns its place.

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?

For a zero-parameter, read-only list tool with no output schema, the description sufficiently describes the returned information: all students, their default dismissal plan, and review status. Nothing essential is missing for an agent to know when to call this tool and what it will get back.

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?

There are zero parameters, so there is nothing for the description to explain about inputs. The description does add meaning by summarizing what the account-wide result set contains, which is sufficient given the empty schema.

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 identifies the resource ('every student on the account') and what is included per student, so an agent can tell this is a list-all tool. It lacks an explicit imperative verb and does not explicitly contrast with siblings like pup_get_student, though the plural framing and account-wide scope make the purpose reasonably clear.

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 implies this is the account-wide student listing and that it surfaces dismissal-plan review status, which gives helpful context. However, it does not explicitly state when to prefer this over pup_get_student, pup_list_plans, or pup_get_default_plans, nor does it mention exclusions.

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