I built DidWork because I kept running into the same problem while using agents inside Pulltrader: the tool call succeeded, the agent said the work was done, and the actual outcome was still wrong. That happened enough times that I stopped treating it like an edge case and started researching it. I ended up documenting 38 failure claims across 8 providers, with the same pattern showing up over and over: agents are usually very good at knowing whether an action ran, but much worse at knowing whether the intended result actually happened. DidWork started as an internal tool to solve that. The idea is simple: give an agent an independent verification step before it moves on. Check the outcome, return a clear pass or fail, and give the agent a chance to repair the work when verification fails. I initially built it for myself, then realized this problem is going to become more important as we give agents more autonomy. Would love to hear how other people are handling this today, especially if you’ve had an agent confidently tell you something was finished when it definitely wasn’t.
