delete_reservation

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

No annotations are provided, so the description carries the full burden. It does disclose a genuine behavioral gate that the schema does not convey — that confirm=true is mandatory (the schema shows only a boolean with default false) — which is valuable for a destructive operation. However, it says nothing about irreversibility, required permissions, or what happens on failure, leaving significant gaps for a delete tool.

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?

Two short sentences, each carrying load: the first names the action and resource, the second states the hard invocation requirement. Nothing is padded or redundant.

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 destructive mutation with no annotations, no output schema, and 0% parameter coverage, the description is too thin. It omits consequences of deletion, error/edge behavior (e.g., unknown macaddr), and any auth requirements an agent would need before invoking it.

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%, so the description must compensate. It explains the semantics of confirm (must be true, not merely defaulted), which is a real addition over the bare boolean schema, but it says nothing about macaddr formatting or behavior, leaving one of two parameters unexplained.

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 gives a specific verb (削除/delete) and resource (DHCP予約/reservation), which cleanly separates it from add_reservation and list_reservations in the sibling set. It is terse but unambiguous about what the tool does.

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?

There is no indication of when to use this tool versus the siblings (add_reservation, list_reservations) and no prerequisites or prerequisites/conditions described. The only guidance offered is the confirm=true requirement, which is an invocation constraint rather than usage context.

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