Common Mistakes to Avoid

Common bot failures usually come from mismatching complexity to the tool’s maintainability model or underestimating the operational work required for multi-step, multi-channel logic.

  • Overbuilding dialog logic without a maintainable structure

    Conversation design can become harder to maintain with many overlapping topics in Microsoft Power Virtual Agents, especially when teams add new intents without a clear topic structure. Advanced branching logic can also become harder to manage in large flows in BotStar, so keeping flows modular matters for long-term updates.

  • Ignoring the operational overhead of multi-channel setup and governance

    Botpress Cloud adds channel setup and permissions overhead when new teams expand publishing surfaces. Cognigy and Dialogflow both require deliberate operational governance for large deployments, because multi-channel routing and stateful behavior depend on well-managed configurations.

  • Treating multi-turn orchestration as if it were single-turn prompting

    Dialogflow can become hard to maintain when multi-turn dialog management grows complex, because entity extraction tuning often needs repeated iteration for edge cases. OpenAI Assistants API also requires careful state handling and run management, because tool-call debugging becomes complex during iterative development.

  • Skipping knowledge grounding until after tool workflows are implemented

    Amazon Bedrock Agents relies on knowledge grounding through Knowledge Bases for Amazon Bedrock, so delaying grounding can leave responses ungrounded during retrieval.
