cancel_leave

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

The description discloses the side effect of restoring balance, which is important behavioral insight. However, it does not mention any prerequisites (e.g., leave status) or potential failure modes.

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 concise at 9 words, front-loading the essential action and effect. No unnecessary verbosity.

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 2-parameter cancel operation, the description covers purpose and side effect but omits return value information despite an output schema existing.

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?

With 0% schema description coverage, the description adds no meaning beyond parameter names. It does not explain what emp_name or leave_id represent or their acceptable formats.

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 (cancel) and resource (leave) with a specific outcome (restore balance). It distinguishes from siblings like apply_leave and get_leave_balance.

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 usage for previously applied leaves but does not provide explicit when-to-use or when-not-to-use criteria, nor references to alternatives.

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