4OVER4 Custom Printing

Contact 4OVER4 support

talk_to_human

Read-onlyIdempotent

Gives the ways to reach 4OVER4's print support team (live chat, ticket, phone); use it when someone asks for a person or a custom print quote. For answers 4OVER4's help already holds use search_knowledge. The topic is optional and files nothing. Returns the support contact page link, where the customer starts a ticket or a live chat. Customer phrases: "can I talk to someone", "I need a custom quote for die-cut folders", "how do I contact support".

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and non-open-world, so the safety profile is covered. The description still adds real context beyond them: the topic 'files nothing' and the tool returns a contact page link where the customer must start the ticket or chat themselves—disclosing that the tool does not actually connect anyone.

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 compact sentences ordered purpose → alternative → caveat, with the trigger phrases last as a matching aid. Slightly list-like with the customer quotes, but every element earns its place.

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?

For a single-optional-param routing tool with full annotation coverage and an output schema, the description covers purpose, the competing option, side-effect behavior, and the shape of the result. Nothing an agent needs to call it correctly is missing.

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% and the single optional topic parameter is fully documented in the schema, so the description only needs to explain optionality—which it does ('The topic is optional and files nothing'). No additional syntax or format guidance is offered, so baseline 3 applies.

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 opens with a specific verb and resource—'Gives the ways to reach 4OVER4's print support team (live chat, ticket, phone)'—and immediately contrasts with the sibling search_knowledge, so an agent can route between them without opening either schema.

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 states exactly when to use it ('when someone asks for a person or a custom print quote'), when not to ('For answers 4OVER4's help already holds use search_knowledge'), and reinforces the trigger with real customer phrasings such as 'can I talk to someone'.

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