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

With no annotations provided, the description carries the transparency burden; it discloses that confirmation is required, but does not mention side effects, prerequisites, or failure modes.

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?

One short sentence of 8 words; all content is meaningful and no redundancy.

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?

The description plus schema/output schema is functional, but lacks alternative guidance and behavioral details; adequate but not comprehensive given the 5 parameters and mutation nature.

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?

Schema has 100% coverage; description adds the ownership constraint ('caller-owned orders') for order_ids, while 'Requires confirmation' mirrors the schema's confirm description.

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?

Description clearly states 'Apply for an invoice covering caller-owned orders' – a specific action (apply) on a resource (invoice) with scope (caller-owned orders), distinguishing it from sibling invoice tools like preview/list/cancel.

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?

Description implies usage context through 'caller-owned orders' and 'Requires confirmation' but does not explicitly name alternatives such as preview_invoice or cancel_invoice, nor when not to use it.

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