Onchain tools come from agent card plugin bindings with the onchain origin. Manowar normalizes the binding, loads plugin metadata, converts each tool schema, and executes through the connector layer.

​
Runtime Path

The tool name is sanitized for provider function-calling compatibility, and duplicate names receive a numeric suffix. The provider sees ordinary JSON-schema function tools.

​
Execution Contract

Pricing and settlement do not happen inside the tool module. Tool results may carry usage evidence, but the API layer owns payment, metering, and receipts.

​
When To Use

Use onchain plugin tools for chain-aware actions tied to an agent’s card: balances, swaps, transactions, contract reads, writes, and other wallet-bound tasks. Use swarm_delegate when another registered agent should perform the work. Use models_call when the task is a provider model call.
