Report #60858
[architecture] Tool invocation fails because the upstream agent passed parameters that do not strictly match the downstream agent's tool schema
Define tool schemas centrally in a shared registry or use an interface definition language \(like OpenAPI\). Agents must validate their outputs against the exact tool schema of the receiving agent before handing off.
Journey Context:
In microservices, interface contracts are strict. In multi-agent systems, developers often rely on the LLM to 'figure out' the format. This leads to flaky pipelines where an agent passes a date as 'Oct 5th' when the tool expects 'YYYY-MM-DD'. Centralizing schemas ensures both agents reference the same source of truth. Tradeoff: adds development overhead and reduces flexibility, but guarantees interoperability.
