firestarter_confirm_order

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

Annotations indicate readOnlyHint=false and destructiveHint=false, but provide little else. The description adds meaningful behavioral context: that confirming notifies the buyer, and that it is the gate before shipping. It also warns about the order_id field misuse (not the exec_... execution id). A small shortfall is not describing the response or side effects (e.g., irreversible nature), accounting for the not-perfect score.

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?

The description is concise and front-loaded with the purpose, though it packs many details into two sentences. The sentences are information-dense but readable and without redundancy, earning a high score slightly below perfect because the long first sentence could be split for readability.

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?

Given the tool complexity (single parameter, clear flow context), the description is nearly complete. It covers when to use, prerequisites, and the parameter gotcha. The only omission is what the success response looks like or potential failure states, but given the tool's simplicity and schema coverage, this is minor.

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 single parameter (order_id) is clearly explained in the description with a specific caveat ('the seller_earnings id, not the exec_... execution id'). The description adds clarity beyond the schema by emphasizing the correct field source, which earns an above-baseline score.

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 the specific action (accepting a pending incoming order), identifies it as step 2 of a fulfillment flow, and names the relevant sibling tools. This distinguishes it from firestarter_ship_order and firestarter_seller_orders explicitly.

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?

The description provides explicit when-to-use guidance, names the prerequisite tool (firestarter_seller_orders), the following tool (firestarter_ship_order), and explicitly notes exclusions ('Only orders still in pending can be confirmed') and 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.
