Singapore Live Taxi Density

gov.sg.taxi_availability
Read-onlyIdempotent

Retrieve live taxi availability across Singapore aggregated to a 5km grid. Returns the top 30 zones by taxi count and the snapshot timestamp to identify areas with taxis.

Instructions

Live taxi positions across Singapore aggregated to a 5km grid — returns the top 30 zones by taxi count and the timestamp of the snapshot. LTA, SG Open Data Licence v1.0

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
refreshNoSet to true to bypass cache and re-fetch the latest snapshot.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
resultNoTool response payload. Shape varies per tool — consult the tool description and inputSchema. May be an object, array, string, or number depending on the upstream provider response.
errorNoPresent only when the call failed. Includes error code, message, request_id, and any provider-specific extras.
Behavior4/5

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

Annotations already indicate read-only, idempotent behavior. The description adds value by specifying the aggregation grid size, limit of 30 zones, and inclusion of a timestamp, providing context 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.

Conciseness5/5

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

Description is extremely concise with two sentences that convey the core purpose, data granularity, limits, and data source. No wasted words.

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?

Given the simple parameter list, good annotations, and presence of an output schema, the description is fully complete. It tells what the tool does and what it returns, leaving no gaps.

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?

Input schema has one optional boolean parameter 'refresh' with a clear description. Schema coverage is 100%, so the description does not need to add more. Baseline score of 3 is appropriate.

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

Purpose5/5

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

The description explicitly states the tool returns live taxi positions aggregated to a 5km grid, providing the top 30 zones by taxi count and snapshot timestamp. This clearly distinguishes it from other gov.sg tools like air quality or weather.

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

Usage Guidelines3/5

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

No explicit when-to-use or when-not-to-use guidance is given, but since there are no sibling tools with overlapping functionality, the need is reduced. The description is sufficient for an agent to understand the tool's domain.

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