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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=false, so the agent knows this is a safe, repeatable, closed-domain read. The description adds the topic scope of the returned content, which is useful, but says nothing further about behavior (e.g., that it returns static documentation with no per-order data). No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence with the subject front-loaded and topics enumerated in a compact parenthetical. The topic list is dense but each item earns its place by telling the agent what questions this tool answers; nothing is padding.

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

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

An output schema exists, so return structure need not be described, and with no parameters the surface area is small. The description covers the informational scope well enough for an agent to decide whether to call it, with only the sibling routing left unstated.

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

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

The tool takes zero parameters, so the baseline is 4. The description correctly implies a no-argument, topic-browsing call and raises no parameter expectations an agent would have to reconcile.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a concrete resource (Inkable Label Co.'s ordering process) and enumerates the topics it covers: pricing flow, proofing, printing, turnaround, shipping, quote forms, and contact info. An agent can tell it is a static informational/FAQ tool. It does not explicitly distinguish itself from siblings inkable_price and inkable_options, which overlap on the pricing and product-option topics mentioned here.

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

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

Usage is only implied: read this when a question is about process, turnaround, shipping, or contact rather than a concrete price or option lookup. No sentence states when to prefer inkable_price or inkable_options instead, which matters because the description itself mentions 'website price' and product forms.

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