apply_leave

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

No annotations provided, so the description carries full burden. 'Apply for leave' implies a write/mutation operation, but no behavioral traits are disclosed (e.g., does it update a database, send notifications, require manager approval?). The description does not describe side effects or system impacts.

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 very short (one sentence plus docstring-like param/return). No wasted words, but could be more informative without becoming verbose. Front-loading is fine.

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 tool's simplicity (2 required params) and existence of sibling tools, the description is incomplete. It lacks details on what happens upon success/failure, required permissions, and how leave_dates should be formatted. The output schema exists but is not shown; the description's return note is vague.

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 coverage is 0%, so description must add meaning. It lists param names ('emp_id', 'leave_dates') but adds no format, constraints, or examples. The leave_dates array lacks item type or date format, leaving ambiguity. The return value is vaguely described as 'Leave application status message'.

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 'Apply for leave for an employee' is nearly a tautology of the tool name 'apply_leave'. It adds minimal new information (specific verb+resource) but does not help distinguish from siblings like 'get_leave_history' or 'get_employee_leave_balance', beyond the obvious action difference.

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?

No guidance on when to use this tool versus alternatives (e.g., when to apply leave vs. check balance or history). No mention of prerequisites, restrictions, or scenarios where this tool is appropriate or inappropriate.

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