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

With no annotations, the description carries the full burden and does so well: it discloses the asynchronous human-in-the-loop fulfillment, the ~1 business day turnaround, the return value (quote number), and a hard rate limit of 5/hour. It also flags the precondition that real name and email must be confirmed with the customer, which is exactly the kind of non-obvious behavioral constraint an agent needs.

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?

Five tight sentences, front-loaded with what the tool does, followed by when to use it, the precondition, the return value, and the rate limit. No filler or repetition of the tool name.

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?

For a 6-parameter, no-annotation mutation tool, it covers purpose, trigger, prerequisites, output and rate limits, and there is no output schema demanding explanation. It could be more complete by routing agents elsewhere for immediate pricing or by noting what happens on a duplicate request, but nothing essential is missing.

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 coverage is 100%, so the baseline is 3, but the description adds real meaning beyond the schema by explaining that the quote is priced by volume plus freight and that name/email must be genuine and customer-confirmed. It says nothing about how items are interpreted or what message should carry (destination ZIP, timeline), leaving those to the schema.

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?

States a specific verb and resource ('Create a real quote request') plus the system it lands in (MaterialHandling.com sales system), which clearly separates it from read-only siblings like search_products, get_product and get_freight_estimate. An agent can tell instantly that this is the submission/intake path, not a lookup.

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?

'Use when the customer wants formal/volume pricing' gives a clear trigger condition, and the described workflow (human specialist prices it, quote emailed in ~1 business day) implies the boundary against instant self-serve estimate tools. It never names an alternative sibling or states an explicit when-not-to-use case, so it falls short of a 5.

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

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

No annotations are provided, so the description carries the burden, and it does disclose that counts are 'live' (i.e., current, not cached) and that category paths map to website URLs. However, it does not state read-only behavior, response shape/size, or whether the tree is paginated or bounded.

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?

Two tight sentences, front-loaded with what is returned and followed by a useful path-to-URL mapping hint. Every sentence earns its place; nothing is padded.

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, annotations, or parameters, the description should characterize the returned data. It says the result is a category tree with counts and hints at path structure, but does not describe the tree shape, node fields, or depth/breadth, leaving an agent guessing about the response format.

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 and the schema is fully documented, so the baseline is 4. There are no parameter semantics for the description to clarify.

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?

States a specific resource and scope: 'the product category tree with live product counts.' This distinguishes it from search_products and get_product, which deal with individual products rather than the category hierarchy. The verb is implied by the name rather than stated, but the noun phrase is precise enough for selection.

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 implied (call this to obtain the category hierarchy, then browse a path). The URL hint suggests follow-up navigation, but there is no explicit when-to-use guidance, no statement of when to prefer this over search_products, and no prerequisites or exclusions.

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

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

With no annotations, the description carries the full burden and does well: it discloses the hard rate limit (10 calls/hour), names the return fields (carrier, service, transit days, price), and describes fallback flagging for parcel/custom-quote items. Gaps remain around auth/prerequisites and error behavior for invalid or non-US ZIPs, keeping it below a 5.

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?

Three tight sentences, front-loaded with the core capability before the return fields and the rate-limit caveat. Every sentence conveys distinct information (what, output, constraints/edge cases) with 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?

With no output schema, the description compensates by enumerating return fields and surfacing the rate limit and flagging behavior, and params are fully covered by the schema. Only minor gaps remain: it doesn't clarify auth requirements or what form the 'flagged' signal takes in the response.

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% (zip, items, sku, qty, liftgate, residential all documented inline), so the schema already carries parameter meaning. The description adds only that items are 'to ship' and implies the multi-product shape, which is baseline value rather than new semantics.

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?

States a specific verb+resource (fetch live LTL freight rates) with scope (US ZIP, one or more products) and explicitly says it uses real carrier pricing, the same engine as checkout. This clearly distinguishes it from siblings like search_products, get_product and create_quote_request, which deal with catalog data or quote creation rather than live rate lookups.

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 implied: get live rate estimates for a shipping destination. The note that parcel-eligible and custom-quote items are 'flagged' hints at alternate paths (UPS parcel, custom quote) but never explicitly names create_quote_request or states when to prefer it. No explicit when-not guidance, so it lands at implied usage rather than actionable routing.

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

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

With no annotations, the description carries the disclosure burden and does so well by enumerating the returned data (pricing incl. volume tiers, stock, lead time in business days, specs, images, URL). It stops short of stating the not-found/error behavior or explicitly confirming this is a non-mutating read.

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 tightly packed sentence, front-loaded with purpose and then the returned fields. No filler and nothing that fails to earn its place.

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 usefully enumerates the return payload, which is the main thing an agent needs. Minor gaps remain around error/empty-result handling and identifier precedence when a value could match multiple forms.

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 coverage is 100% and the single parameter already documents 'SKU, MPN or product slug'. The description repeats the same identifier set, adding no syntax, format, or normalization details beyond the schema, so 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?

States a specific verb (retrieval) and resource (one product) plus the accepted identifier forms (SKU, MPN, slug), so the agent knows exactly what it retrieves. It distinguishes itself implicitly from search_products by scoping to 'one product', but never names that sibling to sharpen the contrast.

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: retrieving full detail for a known identifier. There is no explicit when-to-use/when-not guidance and no pointer to search_products for discovery scenarios, leaving the agent to infer the routing itself.

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

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the return shape (name, SKU, price, availability, lead time in business days, URL), which is useful, but says nothing about pagination behavior, rate limits, auth requirements, or what happens when no match is found.

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?

Front-loaded with the core action, followed by return fields and the sibling routing hint. The long parenthetical brand/category list is somewhat padding, but overall it is compact and each sentence contributes.

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 usefully enumerates return fields, and it points to get_product for depth. For a two-parameter search tool this is largely complete, though error/empty-result behavior and result count handling are unaddressed.

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%, so both parameters (query, limit) are already documented in the schema, including the 1-25 range and default. The description adds no syntax or format guidance beyond what the schema provides, so the baseline of 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?

States a specific verb (Search) and resource (MaterialHandling.com catalog), quantifies scope (15,000+ industrial products) and enumerates representative categories and brands. It is clearly distinguishable from get_product, which it explicitly names as the follow-up tool.

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?

Explicitly routes the agent: use this for catalog search, and 'Use get_product for full specs' defines the alternative and the condition that selects it. It stops short of stating when NOT to use search (e.g., exact-SKU lookup) but the boundary with get_product is clear.

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