Create operation handoff

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

The description discloses that the MCP never signs or submits transactions and that the user executes locally with a browser wallet. Given no annotations are provided, this adds essential behavioral context. However, it does not mention side effects or persistence details, which would elevate transparency further.

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 primary purpose. It uses multiple sentences without redundancy. However, it could be slightly more structured (e.g., separating the exclusions into a list) to improve 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 has 9 parameters, no output schema, and nested objects, the description is insufficient. It only mentions returning a browser URL without explaining the URL format or the nature of the 'offchain human-in-the-loop operation'. The extensive negative guidance is helpful but does not compensate for the lack of positive usage details.

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 0%, meaning no parameter descriptions are provided in the input schema. The description does not explain any of the 9 parameters (type, network, chainId, etc.) or their roles, leaving the agent to infer meaning solely from names.

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 creates an offchain human-in-the-loop operation and returns a browser URL. It specifies that the MCP never signs or submits transactions, distinguishing it from related tools. The verb 'create' and resource 'operation handoff' are directly stated, making purpose unambiguous.

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 guidance on when not to use this tool (e.g., for XDaLa sessions, xgr_validateDataTransfer) and directly names the alternative tool 'create_xdala_session_start_handoff'. It also instructs the agent to report unavailability rather than fallback, demonstrating clear usage boundaries.

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