Get Gc Registered Electors

get_gc_registered_electors

Retrieve the number of registered electors in Hong Kong's geographical constituencies by specifying a start and end year. Use it to compare elector counts across a chosen year range.

Instructions

Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. It does not state that this is a read-only lookup, whether results are cached or current, how the year range is treated (inclusive?), or what happens when no data exists for a year.

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

Conciseness4/5

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

A single front-loaded sentence that states verb, resource, and dimension of aggregation with no filler. It is appropriately sized, though minimal.

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

Completeness3/5

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

An output schema exists so return values need not be explained, and the two required parameters are fully documented in the schema. However, with no annotations and no behavioral notes, the definition is only minimally adequate for invoking the tool correctly.

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?

Schema description coverage is 100%, with both start_year and end_year documented in the schema, so the baseline is 3. The description's 'by year range' confirms the two parameters form a range but adds no syntax, inclusive/exclusive, or valid-range detail beyond the schema.

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?

States a specific verb (Get) and resource (number of registered electors) with clear scope (Hong Kong geographical constituencies, by year range). There are no sibling tools to differentiate from, so the only missing point is that no distinction from any related metric is needed or given.

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

Usage Guidelines2/5

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

The phrase 'by year range' implies the two required year parameters must be supplied, but there is no explicit when-to-use guidance, no conditions or prerequisites, and no note on what the data covers or excludes.

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