Scored 2026-11-06 15:05 across 8 tools

Disambiguation3/5

The product/order read tools (search_catalog, get_product, get_buying_options, get_order_status) are clearly distinct, and the checkout lifecycle is described in detail. However, create_checkout and start_checkout are hard to tell apart at a glance — both 'start' an order, but one runs in-chat and creates a pending order while the other is a read-only hosted checkout_url that creates nothing. update_checkout vs complete_checkout are better separated, but the four checkout-related tools still invite misselection without close reading.

Naming Consistency5/5

Every tool follows a clean verb_noun snake_case pattern: search_catalog, get_product, get_buying_options, get_order_status, create_checkout, start_checkout, update_checkout, complete_checkout. No camelCase mixing or stray verbs. The only weakness is semantic (create vs start), not stylistic, and it belongs under disambiguation rather than naming.

Tool Count5/5

Eight tools is well-scoped for a shop-local ordering flow: two discovery tools, one pricing tool, three checkout-stage tools, a completion tool and an order-status reader. Each earns its place and no tool looks redundant enough to cut outright.

Completeness4/5

The purchase lifecycle is well covered: search → product detail → buying options → create/hosted checkout → update → complete → order status. Gaps are on the post-purchase side: no cancel-order, refund/return, or order history/list-orders tool, which agents will hit when a shopper changes their mind. These are workaroundable for the core buy flow but leave dead ends.

complete_checkoutPlace the orderA

DestructiveIdempotent

Inspect

Place the order. Only after the shopper has approved the total from update_checkout. With the shopper's Stripe shared payment token (spt_...), issued for at least the order total, JENNi charges it and places the order now. Never send card numbers. Delivered by JENNi. payment_token is optional. Without an spt_, call with only checkout_id: the result carries continue_url, the shopper's pay link, and the order is placed when they pay there. With a Link Agent Wallet, make a spend request (credential_type shared_payment_token, the network_id and amount_cents from this checkout's payment block) and pass the spt_ here.

Name	Required	Description
`checkout_id`	Yes
`payment_token`	No	Optional. Stripe shared payment token, starting spt_. Leave it out to get the shopper's pay link (continue_url).
`idempotency_key`	No	Optional. Reuse the same value to retry safely; the retry returns the first result instead of acting twice.

A4.9/5.0

Behavior5/5

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

Annotations declare destructiveHint=true and idempotentHint=true, but the description adds what actually happens beyond the flag: JENNi charges the spt_ and places the order now, the spt_ must be issued for at least the order total, and without it the order only finalizes when the shopper pays at continue_url. That is meaningful consequence and precondition context a bare destructive flag cannot convey, with no contradiction.

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 critical information is front-loaded in the first two sentences, with the fallback and wallet flows trailing. It is dense but nearly every sentence earns its place; the Link Agent Wallet clause is detailed enough to slightly slow scanning, but it is operationally necessary.

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

Completeness5/5

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

For a destructive, payment-charging tool, the description covers prerequisites, both execution paths, security constraints, and even the continue_url return field, while the output schema handles the rest. Nothing an agent needs in order to call it correctly or safely is missing.

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

Parameters5/5

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

Schema coverage is 67%, and the description goes well beyond it: it explains why payment_token is optional, the exact consequence of omitting it (continue_url fallback), and the spt_ issuance requirement plus the network_id/amount_cents source for the wallet spend request. Only idempotency_key is left to the schema, which already documents it well.

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?

The very first sentence states a specific verb and resource ('Place the order'), and the sequencing clause ('Only after the shopper has approved the total from update_checkout') positions it against the sibling update_checkout. An agent immediately understands this is the terminal step of the checkout flow that finalizes and charges.

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?

It gives explicit when-to-use (after shopper approval of the total), when-not/constraint ('Never send card numbers'), and two concrete alternatives with their conditions: call with only checkout_id to get a continue_url pay link, or, with a Link Agent Wallet, make a spend request and pass the spt_. This is the full when/when-not/alternatives pattern.

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

A3.8/5.0

Behavior4/5

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

Annotations already establish that this is not read-only, is idempotent, and is not destructive. The description adds useful behavioral context: no charge occurs until complete_checkout, and the result includes delivery options and order total. It does not discuss authorization, rate limits, or retry behavior beyond the annotation and schema hints.

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 description is short and front-loads the purpose, then adds return and billing context. The final sentence, 'Delivered by JENNi,' repeats the opening phrase and could be removed, but overall it remains efficient.

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 and annotations already covering return shape and safety/idempotency traits, the description is largely complete for initiation. It explains the next step and the billing timing. The main remaining gap is that it does not disambiguate this tool from start_checkout.

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

Parameters4/5

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

Schema description coverage is only 40%, so the description needs to compensate. It identifies the three required top-level inputs (product_id, delivery_address, buyer/contact details), while quantity and idempotency_key are documented in the schema itself. Nested field details are left to the schema, but the description meaningfully frames the required parameters.

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

Purpose4/5

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

The description states a clear verb and resource: start/create an order/checkout. It does not distinguish this from the sibling start_checkout, so an agent cannot tell from the description alone which of those two initiation tools to use.

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?

It implies the workflow by saying nothing is charged until complete_checkout, which suggests this tool precedes that one. However, it gives no explicit when-to-use or when-not-to-use guidance, and it does not address the very similar start_checkout sibling.

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

TDQS

A3.6/5.0

Behavior3/5

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

Annotations already declare readOnly=true, idempotent=true, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely useful behavioral detail that the schema cannot express: the total is pre-tax, the result is per single product, and the mode is effectively fixed to local_delivery. It says nothing about freshness/real-time pricing or failure behavior, so it adds moderate rather than rich context.

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?

Two short sentences, front-loaded with the returned values and followed by the call condition — no filler. The opening is a noun-phrase fragment rather than a verb phrase, which is slightly less scannable, and the parenthetical '(local_delivery)' is redundant with the schema enum.

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 return-shape detail is unnecessary, and all four required parameters are at least acknowledged. For a read-only pricing call this is close to complete; missing only guidance on pricing freshness and what to do when no delivery option is available for the ZIP.

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 0%, so the description carries the burden — and it does name all four parameters (product_id, ZIP, quantity, mode) and clarify the unit of the call is one product. However it omits format constraints the schema encodes (5-digit ZIP pattern, quantity 1–10,000 bounds) and doesn't explain the enum's practical meaning beyond echoing local_delivery.

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

Purpose4/5

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

States a concrete return set (price, delivery promise, total before tax) scoped to a single product_id/ZIP/quantity/mode, which is specific enough for an agent to know what it gets back. It doesn't explicitly differentiate itself from get_product or search_catalog, but the pricing/quoting focus is unmistakable.

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

Usage Guidelines4/5

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

"Call it when the shopper picks a product, before quoting a total" gives a clear trigger condition and a sequencing constraint relative to quoting. It stops short of naming alternatives (e.g. get_product for catalog data) or stating when not to call it.

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

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description adds genuinely new context: the token is private and comes from the shopper's page, the ETA is returned only 'when known' (i.e. may be absent), and no personal details are exposed — useful for deciding whether the output is safe to surface.

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?

Two sentences, no filler. The capability statement comes first, the required input and privacy caveat second, which is the right order for an agent scanning definitions.

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

Completeness5/5

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

An output schema exists, so return values need not be spelled out, and annotations cover the safety profile; the description supplies the remaining pieces an agent needs — what the call reads, what credential it requires, and that no PII is exposed. Nothing material is missing for a one-parameter read tool.

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 100% and the single parameter is fully documented in the schema, including the jos1_ prefix, so the description is not required to carry this. It restates the token's origin and adds the 'private' qualifier (a mild hint about handling), but adds no format or validation detail beyond the schema — baseline 3.

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 ('Read where a JENNi order stands') and then enumerates exactly what is returned: status, delivery ETA, courier tracking, and charge state. The read-only, per-order framing makes it unmistakable against the checkout-creation siblings (create_checkout, complete_checkout, start_checkout), which all mutate a cart rather than inspect an existing order.

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

Usage Guidelines4/5

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

Gives the precondition for calling it — the private order_token from the shopper's JENNi order page — which is the main practical gate on usage. It does not explicitly say when not to use it or name an alternative, but no sibling offers order-status lookup, so the risk of misrouting is low.

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

B3.4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description usefully adds that price and delivery are resolved locally at the ZIP, which is real behavioral context beyond the annotations. It stops short of stating the fallback when no ZIP is supplied or what happens for an invalid/unknown product_id.

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?

A single tightly packed sentence with the resource and its identifier front-loaded, and no filler. The telegraphic phrasing ('at the ZIP') is slightly compressed at the cost of a little readability, but nothing is wasted.

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

Completeness3/5

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

An output schema exists, so return-value explanation is not required, and the annotations carry the safety semantics. What is missing is guidance on the two optional locator parameters and on failure modes for a bad product_id or ZIP, which matters for a three-parameter lookup tool.

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 67%: zip and market are documented in the schema, while product_id has no description there. The description compensates partially by framing product_id as selecting exactly one product and by tying zip to localized price and delivery, but it never mentions the market parameter or the zip-versus-market precedence.

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

Purpose4/5

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

States a specific verb-and-resource: details for one product_id, and enumerates the returned content (description, images, sizes, colours, price, delivery). This implicitly separates it from search_catalog, which returns many products, but the distinction is never made explicit.

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: an agent must infer this is the lookup to call once it already holds a product_id. There is no explicit when-to-use versus search_catalog or get_buying_options, and no note about what to do when the id is unknown or the zip is absent.

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

search_catalogSearch productsA

Read-onlyIdempotent

Inspect

Search in-stock products JENNi can deliver to a 5-digit US ZIP: local delivery. Every product returned can be ordered; price is per unit, before the delivery fee. A product with variants and no price is a size or colour family: buy one of its variants. Sized goods are often listed one size per product: put the size in the query and match it against size or title. Put a price limit in max_price, not the query; keep the query to brand, product type and size. If it returns product_not_found, search once more with fewer words before telling the shopper nothing matched. Pass fulfillment_mode to search one mode. More results: call again with page+1 while page < paging.total_pages.

Name	Required	Description
`zip`	No	5-digit US ZIP code the shopper is in, e.g. 78205.
`page`	No	1-based results page; call again with page+1 while page < paging.total_pages.
`limit`	No	Products to return (default 10).
`query`	Yes	What the shopper wants, e.g. "running shoes".
`market`	No	Market key, e.g. san-antonio-tx. Used when no zip is given.
`max_price`	No	Highest price the shopper will pay, in US dollars, e.g. 120. Put a price limit here, not in the query.
`fulfillment_mode`	No	Search one mode only. Lists local delivery offers.

A4.8/5.0

Behavior5/5

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

Annotations already declare readOnlyHint, idempotentHint and a closed-world scope, so the safety profile is covered; the description goes well beyond it by disclosing pricing semantics (per unit, before delivery fee), the orderability guarantee, the variant/family rule ('a product with variants and no price is a size or colour family'), and the sized-goods listing quirk. The error-recovery rule for product_not_found is exactly the kind of behavior an agent cannot infer from structured fields.

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?

The scope constraint is front-loaded, then rules follow in priority order (pricing, variants, sizing, error retry, pagination). Every sentence states a distinct operational rule with no restated boilerplate.

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, return values need not be explained, and the description still references paging.total_pages for the loop. The only minor gap is that the zip-versus-market precedence is left to the schema rather than stated in prose, though nothing essential for a correct call is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3; the description earns an increment by adding routing meaning the schema does not carry, notably the max_price-versus-query split and the instruction to match size tokens against size or title. It adds little on zip, market or limit beyond what the schema already says.

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?

The opening names a specific verb and resource ('Search in-stock products JENNi can deliver to a 5-digit US ZIP'), constrains the result set to orderable products, and implicitly separates it from get_product and get_buying_options by emphasizing catalog search. An agent knows exactly what this returns 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 Guidelines5/5

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

Explicit rules cover when to use each parameter and what not to do: 'Put a price limit in max_price, not the query', 'keep the query to brand, product type and size', 'Pass fulfillment_mode to search one mode', and a defined retry ladder ('If it returns product_not_found, search once more with fewer words'). Pagination guidance is likewise conditional and actionable.

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

start_checkoutStart checkoutA

Read-onlyIdempotent

Inspect

Returns a hosted checkout_url for an exact product and selected fulfillment mode using the delivery ZIP or address. For several products, pass items instead of product_id: one checkout_url puts them all in one basket. JENNi selects the source internally. The buyer reviews delivery, tax and the total, enters payment details, and places the order on the hosted page. This read-only tool creates no order, reservation or charge. The final checkout page verifies current price and availability.

A3.8/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, and the description reinforces this with the high-value clarification that no order, reservation or charge is created. It also discloses that the hosted page re-verifies price and availability at purchase time, which is genuine behavioral context not present in the annotations. It stops short of auth requirements, rate limits, or expiry of the generated link.

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?

It is front-loaded with the return value and the multi-item rule, which are the two things an agent most needs. The last two sentences describing the buyer's review-and-pay flow are somewhat expansive relative to the tool's single job, costing a little tightness.

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 and full schema coverage, the description does not need to explain return shape, and it covers the important safety story (no order/charge) plus linkage to `get_buying_options` via delivery_promise. The one material gap is sibling differentiation against `create_checkout`/`complete_checkout`, which matters given how close those names are.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3, but the description adds meaning the schema does not: the ZIP-or-address alternative for delivery location, and that passing `items` instead of `product_id` yields one basket in a single `checkout_url`. Those are semantic clarifications about mutual exclusivity and outcome, not restatements of field docs.

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

Purpose4/5

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

The description opens with a concrete verb and output ('Returns a hosted checkout_url') scoped to a product and fulfillment mode, and it explains the multi-item variant via `items`. It never distinguishes itself from the sibling `create_checkout`, `update_checkout` or `complete_checkout`, so an agent cannot tell from the text alone which of these similarly named tools to pick.

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?

'For several products, pass items instead of product_id' gives real selection guidance between two parameter paths. However, there is no guidance on when to use this versus `create_checkout` or `complete_checkout`, nor any stated prerequisites (e.g. must a buying-options read happen first). Usage is implied by the buyer-flow narrative rather than stated.

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

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnly=false, idempotent=true, destructive=false, openWorld=false, so the safety profile is covered. The description adds genuinely non-obvious behavior beyond them: the same endpoint doubles as a read when passed only checkout_id, and the returned total depends on a delivery option having been selected. It does not mention preconditions such as order state or that the address is US-only.

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?

Three tight sentences, front-loaded with the primary action and with the cheap re-read path stated early. The opening clause 'Choose local_delivery' is slightly jarring out of context since it omits the parameter name, and 'change ... contact details' is looser than the schema's buyer object.

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?

Return values need not be explained because an output schema exists, yet the description still usefully notes the total. For a 6-parameter tool with nested objects and only one required field, the main remaining gap is the absence of any prerequisite or state guidance (e.g. what an order must contain before a delivery option can be chosen).

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

Parameters4/5

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

Schema description coverage is only 17%, so the description must carry meaning, and it does map the mutable surfaces: quantity, delivery_address, buyer contact details, and the fulfillment_mode value 'local_delivery'. It does not cover the nested address constraints (2-letter state, US-only country, ZIP pattern) or the idempotency_key, though the schema documents the latter itself.

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 specific mutations (choose a delivery option, change quantity, address, or contact details) on a named resource and anchors it to the sibling that creates it: 'an order started with create_checkout'. An agent can distinguish this from create_checkout, complete_checkout, and get_order_status without opening any schema.

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

Usage Guidelines4/5

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

Gives explicit invocation modes: call with only checkout_id to re-read, and supply fields to mutate. It also implies the sequencing rule that the total appears only 'once a delivery option is chosen'. It does not state exclusions relative to get_order_status (read a completed order) or complete_checkout, which keeps it out of the top band.

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