create_reservation

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 states the tool creates a reservation but doesn't mention whether it requires permissions, what happens on conflicts, if it sends notifications, or what the response looks like. For a mutation tool with zero annotation coverage, this leaves critical behavioral traits undocumented.

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 brief and front-loaded with the core purpose. The second sentence provides useful context about rooms and time intervals without redundancy. However, it could be more structured by separating room listing from time slot information for better readability.

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 mutation tool with no annotations and no output schema, the description is incomplete. It doesn't cover error conditions, response format, authentication needs, or interaction with sibling tools. Given the complexity of creating reservations and the lack of structured data, more contextual information is needed.

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 100%, so the schema fully documents all parameters. The description adds minimal value by listing room names (already in the enum) and noting time slots are in 30-minute intervals (implied by schema patterns but not explicitly stated). This meets the baseline for high schema coverage without significant enhancement.

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 ('Create a new room reservation') and specifies the resource ('room reservation'), distinguishing it from sibling tools like delete_reservation or update_reservation. It provides specific context about available rooms and time slot intervals, making the purpose explicit and actionable.

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 provides no guidance on when to use this tool versus alternatives like update_reservation or get_available_rooms. It lists available rooms but doesn't mention prerequisites (e.g., authentication), conflicts with other reservations, or when to choose this over other reservation-related tools.

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