get_city_guide

Read-onlyIdempotent

Use this when the user wants an orientation overview of a city for trip planning. Returns a ranked list of the city's most popular bookable experiences (search rows); derive the dominant categories and price levels from those rows rather than expecting a structured guide payload.

  3. First observed

TDQS

A4.3/5.0
Behavior5/5

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

Annotations already establish this as a safe, read-only, idempotent operation. The description adds valuable behavioral context beyond that: the response is actually a ranked list of search rows, and the agent must derive categories and price levels from those rows rather than expecting a structured guide. This prevents a major misinterpretation of the return payload.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences: the first states the trigger use case, the second states the return shape and the key interpretive instruction. Every sentence earns its place with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple, the schema fully documents its parameters, annotations cover safety, and an output schema exists. The description fills the one important gap by explaining how to interpret the returned rows. Nothing essential is missing for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already describes all three parameters in full, so the schema carries the semantic weight. The description adds no additional parameter-level detail, which is acceptable given the 100% schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns an orientation overview of a city for trip planning: a ranked list of popular bookable experiences. It also clarifies that no structured guide payload should be expected. While it doesn't explicitly name sibling alternatives, the use case and output format are specific enough to set it apart from search and tip tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description opens with an explicit when-to-use condition: 'when the user wants an orientation overview of a city for trip planning.' It doesn't enumerate alternatives or exclusions, so it stops short of full routing guidance, but the context is clear and actionable.

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