wattpad_languages

Read-only

List the story languages Wattpad search can filter by and return each language's id and native name. Use this to find the language id for the language filter of wattpad_search; the list is fixed and takes no input.

A4.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds the useful traits that the list is fixed and takes no input, which tells the agent results are cacheable and non-variable. It doesn't mention size of the list or output ordering, which keeps it from a 5.

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 front-loaded sentences: purpose and payload first, then the downstream use case. No filler or restatement of the tool name.

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?

An output schema exists, so return values needn't be spelled out, yet the description still names the two key fields. Purpose, usage, arglessness and result stability are all covered for a simple static-lookup tool.

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

Parameters4/5

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

Zero parameters, so the baseline is 4. The description reinforces this with 'takes no input', preventing an agent from inventing or expecting arguments.

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?

States a specific verb and resource ('List the story languages Wattpad search can filter by') plus the exact fields returned ('id and native name'). This immediately distinguishes it from the sibling wattpad_search, which consumes its output.

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

Usage Guidelines5/5

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

Explicitly says when to use it: 'Use this to find the language id for the language filter of wattpad_search'. Also notes 'the list is fixed and takes no input', so an agent knows not to parameterize or retry for different results.

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