get_checkout

Read-only

Read checkout by checkout_id. Returns persisted order status, payment_status, payment_method, items, customer, total_zar and currency. Initial order status is started, not pending. This tool does not return a previously generated payment_url: retain the complete_checkout response in caller context.

  5. First observed

TDQS

A4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered; the description nonetheless adds genuinely non-obvious behavior. 'Initial order status is started, not pending' preempts a common misreading, and the warning that payment_url is not persisted here has real operational consequences (retain complete_checkout's response).

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

Conciseness5/5

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

Three short sentences, front-loaded with the primary action, followed by return contents and then two caveats. Every sentence carries distinct information; nothing is repeated from the schema or annotations.

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?

With an output schema present, the description needn't define return shape, and it still covers the key semantic gotchas (initial status, missing payment_url). It stops short of saying what happens when the checkout_id is unknown or whether cancelled/expired checkouts are still readable.

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 0% — the single property has no description at all. The description only reiterates 'by checkout_id' without adding format, source, or failure behavior for an unknown ID, so it barely compensates for the schema gap, but the lone parameter's meaning is clear from the name.

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+resource ('Read checkout by checkout_id') and immediately enumerates the persisted fields returned. It also carves out a scope boundary against complete_checkout by noting the generated payment_url is not included, so an agent can distinguish it from sibling tools without opening the schema.

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

Usage Guidelines3/5

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

Usage is only implied: the payment_url sentence implicitly routes the agent to complete_checkout for that value, and 'by checkout_id' suggests a post-create_checkout lookup. There is no explicit when-to-use vs get_cart/get_order guidance or stated preconditions.

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