Jupiter Cancel D C A

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

The description adds key behavioral context beyond annotations by stating that the tool creates an 'unsigned transaction,' meaning it does not directly cancel the order but prepares a transaction for later signing. This is valuable given destructiveHint=true, as it clarifies the mutation is deferred.

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 extremely concise with two sentences. The first sentence delivers the core purpose, and the second provides ecosystem context. No unnecessary words or repetition.

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's moderate complexity and the presence of an output schema, the description adequately covers the essential outcome ('unsigned transaction'). However, it could briefly note that the order must be owned by the provided user wallet to improve completeness.

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 input schema already describes all parameters sufficiently. The description adds no additional semantic value for the parameters (e.g., explaining the enum values or the optional computeUnitPrice).

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 tool's purpose: 'Create an unsigned transaction to cancel a DCA recurring order.' It uses a specific verb ('cancel') and resource ('DCA recurring order'), effectively distinguishing it from sibling tools like jupiter_cancelLimitOrder which cancel limit orders.

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 does not provide specific guidance on when to use this tool versus alternatives. The SAP MCP context note is generic for all Jupiter tools and does not help differentiate from siblings like jupiter_cancelLimitOrder. No prerequisites or use-case scenarios are mentioned.

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