travel_set_agent_budget

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 only states a write operation (set) without disclosing behavioral traits like overwrite behavior, authorization needs, rate limits, or side effects. Significant gaps remain.

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 single sentence is concise, but the extreme brevity omits critical information. It is not a model of effectiveness; it sacrifices completeness for shortness.

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?

Given no annotations, no output schema, and only two parameters with zero coverage, the description is severely incomplete. It fails to address return values, prerequisites, error conditions, or confirmation of the set action.

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 and no parameter explanation in the description, the agent receives no semantic context for 'agentId' or 'limitUsd'. The description does not compensate for the missing schema details.

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 tool's function: setting a USDC spend cap for an agent before autonomous booking. The verb 'set' and resource 'agent budget' are specific, and the context distinguishes it from sibling tools (authorize, cancel, confirm bookings, etc.).

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 'before it books autonomously' implies a usage timing, but no explicit guidance on when not to use or alternatives is provided. Given no sibling tools for budget management, the guidance is minimal but not misleading.

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