seeing while working with LLM systems:<\/p>\n<p>The assistant <em>sounds<\/em> correct\u2026<br \/> but nothing actually happens.<\/p>\n<p>Example:<\/p>\n<blockquote>\n<p>\u201cYour issue has been escalated and your ticket has been created.\u201d<\/p>\n<\/blockquote>\n<p>But in reality:<\/p>\n<ul>\n<li>No ticket was created<\/li>\n<li>No tool was triggered<\/li>\n<li>No structured action happened<\/li>\n<li>The user walks away thinking it\u2019s done<\/li>\n<\/ul>\n<p>This feels like a core gap in how most datasets are designed.<\/p>\n<p>Most training data focuses on: \u2192 response quality<br \/> \u2192 tone<br \/> \u2192 conversational ability<\/p>\n<p>But in real systems, what matters is: \u2192 deciding what to do<br \/> \u2192 routing correctly<br \/> \u2192 triggering tools<br \/> \u2192 executing workflows reliably<\/p>\n<p>We\u2019ve been exploring this through a dataset approach focused on <strong>action-oriented behavior<\/strong>:<\/p>\n<ul>\n<li>retrieval vs answer decisions<\/li>\n<li>tool usage + structured outputs<\/li>\n<li>multi-step workflows<\/li>\n<li>real-world execution patterns<\/li>\n<\/ul>\n<p>The goal isn\u2019t to make models sound better, but to make them <strong>actually do the right thing inside a system<\/strong>.<\/p>\n<p>Curious how others here are handling this:<\/p>\n<ul>\n<li>Are you training explicitly for action \/ tool behavior?<\/li>\n<li>Or relying on prompting + system design?<\/li>\n<li>Where do most failures show up for you?<\/li>\n<\/ul>\n<p>Would love to hear how people are approaching this in
