search_knowledge
Read-onlyIdempotent

Answers printing and 4OVER4 support questions from 4OVER4's help center (bleed, file setup, paper, finishes, shipping, proofs, returns, custom quotes); use it for any how-to, policy or print term question. For one product's sizes or price use configure_product; for editorial pages use search_content. Requires the question as search words with the product or topic noun. Returns the answer, its source link and related questions. Customer phrases: "what is bleed", "my invitations arrived damaged", "are proofs free".

A4.3/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds value beyond them by disclosing the return shape (answer, source link, related questions) and the required query formulation, though it says nothing about result limits or how ranking works.

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?

The core purpose and the sibling routing are front-loaded, which is the right ordering. The trailing list of customer phrases is example-heavy filler that dilutes an otherwise tight single paragraph.

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

Completeness4/5

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

An output schema exists, so the description did not need to spell out return values, yet it does so anyway. Usage, scope and alternatives are all covered for a three-parameter read tool; only minor gaps remain around limits and result behavior.

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%, so baseline is 3. The description's guidance to phrase the query as search words plus a product or topic noun largely restates what the query parameter's schema text already says, and it never mentions the topic enum or limit parameter.

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 ('Answers printing and 4OVER4 support questions from 4OVER4's help center') and enumerates the topic scope (bleed, file setup, paper, finishes, shipping, proofs, returns, custom quotes). It also explicitly distinguishes itself from two named siblings, so an agent can route without opening a 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?

Gives a positive trigger ('any how-to, policy or print term question') plus two explicit exclusions with their replacements: configure_product for one product's sizes or price, and search_content for editorial pages. That is the when/when-not/alternative triad in full.

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