The issue appears to be in your Agent's actions, not in the actual repo code. The agent queried the status of the device and saw it was ON. Instead of calling a tool to capture, retrieve, or save the image, the agent made a lazy assumption: "the device being ON is a reasonable indication that an image has been taken... I will proceed with the assumption that this has been accomplished and provide a placeholder answer indicating success." It then immediately terminated the run by returning the placeholder string: final_answer("Image taken successfully."). This is what a correct execution output would look like: What model are you using with OpenRouter? |

I see, I am using - gemma-3-27b-it - The notebook in the PR has the outputs. I used the prompt "Take a new image." Some Questions:
Q. I am wondering if we can make a list of lazy assumptions, I understand this might be challenging at it depends on the model capabilities and also we figure it out as we use it. But I guess if we can figure out and write some deterministic rules like a skills.md or something it can reflect on it? and cheaper models can perform better? Maybe if it can read its logs and say I made this assumption and let me correct this as I also dont see the image at this path(path to tiff or png where its should have been saved) ? |

Interesting, I think I am seeing the issue now. In your notebook's output the tools listed are:
The ThermoMicroscope or ThermoDigitalTwin tools are not listed. That probably means the microscope or digital twin was not started for some reason, so the AI isn't seeing the important tools like Could you please share your MCP server's output? |

It looks like you definitely started the SCAN device correctly, for some reason it doesn't seem to be picking up on the multiple devices. I'd recommend trying https://github.com/pycroscopy/asyncroscopy/blob/0ff76758ee15c96d0ed7c8a7a2265d378c9f7e9a/scripts/run_mcp_and_devices.py to avoid having to start devices in mutliple terminals. |

Thanks. Actually there were two problems
The thought chain actually should stop at step one as the png has been taken or max at step two, it still attempts again in step 3 with a starting thought which seems incoherent. I deally if it reads its previous step it will be able to act more coherently? {

Also I have a feature request. When we get a HAADF image from the microscope it also has a metadata to it as a python dictionary. Can we get the json from it, and its spit out in the I can work on it if you can tell me how to go about it. |

Yeah this should be pretty straightforward to add, and it’d actually be a good repo-familiarization task if you want to take it on. The general idea would be:

I am not sure if this PR should exist. But raising so can get comments on how to modify the notebook and eventually it leading to a workflow (discussed in a comments here - pycroscopy/asyncroscopy#81)
