hold_fulfillment_order

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

With no annotations provided, the description bears full responsibility for disclosing behavioral traits. It only says 'pause fulfillment,' omitting important details like reversibility, side effects, prerequisites, or impact on downstream processes. The existence of a separate release_fulfillment_hold sibling suggests holds are reversible, but this is not mentioned.

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 two sentences with no filler. It front-loads the core action and then adds practical usage context. Every sentence contributes value.

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?

The description covers the basic purpose and use cases, but for a mutation tool with 4 parameters and no output schema, it does not explain the full lifecycle impact (e.g., that holds can be released later, or how the hold affects order status). It is adequate but has clear gaps.

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 schema covers 100% of parameter descriptions, so the baseline is 3. The description's mention of reasons ('inventory issues, customer requests') aligns with the enum but adds no meaning beyond the schema's own descriptions. No extra parameter context is provided.

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 clearly states the action ('Apply a fulfillment hold') and the target resource ('on a fulfillment order'). It also signals the intended effect ('pause fulfillment'), which distinguishes it from related tools like release_fulfillment_hold.

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 explicitly lists use cases ('inventory issues, customer requests, or other reasons'), providing clear context for when to apply a hold. However, it does not mention alternatives or explicitly state when not to use this tool, so it falls just short of full guidance.

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