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

With no annotations, the description carries full burden but discloses nothing beyond the mutation type. It doesn't specify if updates are partial (PATCH-like) or full replacement, idempotency, side effects (notifications), or error handling for non-existent bookings.

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?

Extremely concise at four words with zero redundancy. Every word earns its place, though the brevity borders on under-specification given the tool's complexity with nested objects and six parameters.

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?

Inadequate for a tool with nested objects, multiple optional update fields, and no output schema or annotations. The description omits critical context like update semantics (partial vs full), return values, and which booking aspects are mutable.

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?

The schema has 100% description coverage, so the baseline is 3. The description adds no parameter-specific context (e.g., that bookingId likely comes from get_booking, or that only provided fields are updated), but the schema adequately documents individual parameters.

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 states the basic action ('Update') and resource ('existing booking'), distinguishing it from create_booking. However, it fails to differentiate from cancel_booking or clarify what specific aspects can be modified, leaving the scope ambiguous.

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 provided on when to use this versus cancel_booking for cancellations, or prerequisites like obtaining the bookingId. The description lacks any 'when-to-use' or 'when-not-to-use' context.

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