Testing Conversations in Orchestrate via Agentic Skill

Summary

The new `watsonx-orchestrate` skill for IBM Bob enables developers to directly access and test IBM watsonx Orchestrate systems, streamlining agent development workflows. This open-source skill automates the setup of the Orchestrate ADK's command line interface (CLI) and facilitates running tests. It supports Test-Driven Development (TDD) for agentic workflows by generating agents and tools, importing them into Orchestrate environments, and executing live tests. The skill handles both single-turn and multi-turn conversation scenarios, reading starter prompts from agent YAML definitions to construct test cases and aggregate results into reports. To optimize token usage and overcome the interactive nature of the `orchestrate chat ask` CLI command, a wrapper script, `wxo-chat.sh`, was created. This script replicates the programmatic behavior of the Orchestrate REST API without requiring the MCP server, executing locally to manage agent conversations and provide structured JSON output including `thread_id`, `final_message`, and `reasoning_trace`.

Key takeaway

For AI Engineers developing conversational agents on IBM watsonx Orchestrate, integrating the `watsonx-orchestrate` skill into your workflow is essential. It automates agent testing directly within live environments, ensuring functional reliability for both single-turn and complex multi-turn interactions. You should adopt this skill to implement robust Test-Driven Development practices, reducing manual verification efforts and accelerating agent deployment with confidence. Prioritize read-only tests by default to maintain safety.

Key insights

The `watsonx-orchestrate` skill automates agent testing in live Orchestrate environments, supporting TDD for conversational AI.

Principles

• TDD is crucial for agentic workflows.
• Test multi-turn conversations, not just happy paths.
• Verify deployed agents before handover.

Method

The skill generates agents/tools, imports them into Orchestrate, then runs single-turn and multi-turn smoke tests using `wxo-chat.sh` or the MCP server, evaluating results into a report.

In practice

• Use `wxo-chat.sh` for programmatic agent testing.
• Derive test cases from agent `starter_prompts`.
• Prioritize read-only tests for safety.
