Get modifier

loyverse_get_modifier

Retrieve a single modifier by its ID from the Loyverse API. Use to access modifier details for inventory or menu management.

Instructions

Get a single modifier by id (GET /modifiers/{id}). Field names follow the Loyverse API v1.0 (developer.loyverse.com/docs). If a call fails with a 400, the error message from Loyverse is returned verbatim — adjust the fields and retry.

Input Schema

NameRequiredDescriptionDefault
idYesThe modifier id.
Behavior3/5

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

No annotations; description adds error handling detail (400 response with verbatim error) and references API docs, but omits response structure and security context.

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?

Three sentences, each adds value: purpose, API reference, error handling. Efficient but first two could be merged.

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?

Adequate for a simple 1-param GET tool; lacks response description and any prerequisite notes, but error handling and API ref compensate partially.

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 coverage is 100%; description only restates endpoint, adding no new parameter meaning beyond schema's 'The modifier id.'

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?

Explicitly states 'Get a single modifier by id' with HTTP method and API version. Clearly distinguishes from list tool and other CRUD siblings.

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?

Implies usage for retrieving one known modifier via id, but provides no explicit when-to-use vs listing or alternative tools.

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