get_available_gifts

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

Annotations already indicate this is a safe, read-only, idempotent operation. The description adds the scoping qualifier 'can be sent,' but no additional behavioral context (e.g., authentication, pagination, global scope). It provides marginal value beyond annotations.

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 a single clear sentence with no superfluous words. It is front-loaded and appropriate for a tool with no parameters and simple semantics.

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?

The tool is simple and has strong annotations, but the description does not explicitly clarify that this returns a global catalog rather than user- or chat-specific gifts. With several similar sibling tools, a bit more context would improve completeness.

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 tool takes zero parameters, so the schema trivially covers everything. The description adds no parameter details, but none are needed. Baseline of 4 is appropriate due to zero 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 exact resource (list of gifts) and the qualifier 'can be sent' clearly distinguishes it from sibling tools like get_user_gifts or get_chat_gifts. It is specific and unambiguous.

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 phrase 'that can be sent' implies this is the catalog of available gifts, but it does not explicitly state when to use this vs. alternatives such as get_user_gifts or get_business_account_gifts. Usage context is implied, not stated.

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