plan_trip_route_local_tool

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

With no annotations, the description carries the full transparency burden. It adds useful behavioral details ('deterministic' and 'offline') and mentions the daily food recommendation feature. However, it does not explain what 'offline' means in practice, data sources, limitations, or any side effects, leaving important behavioral aspects undisclosed.

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, front-loaded sentence with no filler or redundant content. It is efficient and to the point, though it could be expanded with more useful context without becoming verbose.

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?

Despite having an output schema, the tool has 7 parameters and no parameter descriptions. The description does not explain required inputs, how 'deterministic offline' affects behavior, or how this tool differs in usage from sibling tools. This is insufficient for an agent to reliably configure and invoke the tool correctly.

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%, yet the description provides no parameter-level guidance. None of the 7 parameters (origin, destination, days, budget_level, pace, interests, travelers) are explained, and the description does not compensate for the missing schema descriptions. The phrase 'daily food recommendations' only loosely hints at 'days' without clarifying its semantics.

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 'Plan a deterministic offline route with daily food recommendations' clearly states the action (Plan), the resource (route), and the distinguishing feature (offline, deterministic, daily food recommendations). It differentiates from sibling tools like plan_trip_route_tool by emphasizing 'offline' and from recommend_food_experiences_tool by integrating food into the route.

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 implies use cases (offline and deterministic planning), but it does not explicitly state when to use this tool versus alternatives such as plan_trip_route_tool. No exclusions or explicit alternative guidance is provided, leaving the agent to infer usage context.

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