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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds genuinely useful behavior beyond that: an authentication prerequisite ('needs their sign-in'), a scope restriction, and the full set of terminal/user states the order can be in.

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?

Compact and front-loaded: the status enumeration comes first, then the two constraints. Slightly terse phrasing ('the person who allowed you') costs a bit of clarity, but there is no filler.

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?

With no output schema, the description compensates by enumerating the possible return states and noting a link back to the manage flow, plus the auth requirement. That is close to complete for a two-parameter read tool, though it does not say what happens for an invalid or unrecognized order.

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 description coverage is 100%, and the two parameters (order, business) are documented in the schema with accepted formats, so the description needs to add little. It adds nothing about parameter usage (e.g., whether business and order must match), so the baseline 3 applies.

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 states a specific verb+resource (retrieve where a prepared order stands) and enumerates the three possible statuses with meanings, which is more than a restatement of the name. It does not explicitly contrast itself with siblings like prepare_booking or get_free_times, so it falls short of a 5.

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?

It gives clear applicability context: the tool covers only orders of the person who authorized the agent, and requires their sign-in. No sibling alternative is named for the reverse case, but the scoping condition is explicit and actionable.

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