list_pending_requests

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a read-only operation (listing requests), which is consistent with a read operation, but doesn't explicitly state that no changes are made. It also doesn't disclose what happens for edge cases like managers with no direct reports (empty list?) or whether the manager_id must be unique. The read-only nature is implied but not stated.

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 concise sentence that conveys the core purpose efficiently with no wasted words. It's appropriately short for a tool with only one parameter. However, it's slightly under-specified given the complete lack of parameter documentation, so it could arguably contain a bit more useful detail without becoming verbose.

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 simple read-only tool with one parameter and no output schema, the description captures the core purpose adequately. The key gap is the parameter semantics — with 0% schema coverage and only one param, the description should clarify what manager_id refers to and its expected format. However, given the tool is inherently simple (list of requests), it doesn't need extensive elaboration.

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 0%, meaning the description must compensate. The single parameter 'manager_id' is described only as 'Manager Id' in the schema. The description says requests are for 'employees reporting to a manager,' which partially clarifies that manager_id identifies the manager, but it doesn't specify the format (name? email? UUID?), whether it refers to the current user's ID, or any validation requirements.

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), resource (pending leave requests), and scope (employees reporting to a manager). It's distinguishable from sibling tools like apply_for_leave, approve_leave, reject_leave since those are action-oriented, while this is a read/list operation. However, it doesn't explicitly differentiate it from check_leave_balance which is also a read operation, though the resource differs (balance vs requests).

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 for managers to see pending requests from their direct reports, which provides some context for when to use it. However, there's no explicit when-not-to-use guidance or mention of alternatives among the siblings (e.g., no mention of how this differs from check_leave_balance for viewing leave status). The scope is implied to be 'pending' only, not approved or rejected requests.

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