List invoice templates

list_templates

Discover available invoice templates for various industries. Returns each template's slug, name, description, and URL to help you choose and build a custom invoice.

Instructions

List the industry-specific invoice templates available on Blank Invoice Maker (https://blankinvoicemaker.com). Returns each template's slug, name, description, and page URL. Use this to discover templates; build a custom invoice with create_invoice.

TDQS

A4.7/5.0
Behavior4/5

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

No annotations are provided, so the description fully carries the burden. It discloses that the tool lists templates (read-only) and returns specific fields, but does not mention any additional behavioral aspects like rate limits or data freshness. Still sufficient for a simple list operation.

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?

The description is two concise sentences, front-loading the purpose and linking to the sibling tool. No extraneous information.

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 tool's simplicity (zero parameters, no output schema), the description fully covers what it does, what it returns, and how it relates to the sibling tool. No gaps.

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?

The tool has no parameters, and the schema covers 100% of the input. The description does not need to add parameter info; it correctly omits any.

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 clearly states the tool lists invoice templates, specifies the returned fields (slug, name, description, page URL), and distinguishes it from the sibling tool create_invoice by indicating its discovery purpose.

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?

It explicitly says to use this tool for discovering templates and to use create_invoice for building a custom invoice, providing clear context and an alternative.

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