wtf is open-engineer?

Open Engineer is an open source engineering workbench built on top of a project called OpenCode. It packages engineering and science-focused skills and workflows on top of upstream OpenCode, and its first release targets 64-bit Windows. The README is careful to say that it does not add a private login system, a model proxy, a shared API key, or any bundled default AI model. Instead, models are configured through OpenCode's own provider settings, which can point to services like OpenCode Zen, Anthropic, OpenAI, OpenRouter, Gemini, Ollama, and others. The Windows preview installer is unsigned in this first version, so the README recommends checking the provided SHA256 file before installing anything downloaded from GitHub Releases. At build time, Open Engineer bundles a set of skills for scientific and engineering work. These include tools for searching scholarly papers and resolving identifiers, working with PDF, Word, and Excel files, reproducing simulation papers from evidence, scoping simulation requirements, and previewing geometry before sending it to a CAD tool or solver. It also bundles one skill per supported engineering tool, covering software such as COMSOL Multiphysics, Abaqus, Ansys Fluent, Ansys Workbench, Ansys Mechanical, Simcenter Flotherm, Simcenter STAR-CCM+, Ansys HFSS, Altair HyperMesh, MATLAB, Stata, Autodesk Fusion, and Rhino, plus guidance for Cadence Virtuoso and Spectre. Each of these routes an agent's work against the real software, whether that means working with saved files, running batch jobs, or connecting to a live session, and the README notes that the Cadence-related skills do not bundle any of Cadence's own licensed tools, credentials, or servers. External skills used by the project are locked to a specific source repository, commit, file path, and file checksum, and the generated skills folder itself is not meant to be hand-edited. The bundled paper-search skill defaults to public sources such as Crossref, arXiv, Europe PMC, DataCite, and OpenAlex, with optional contact-email settings for some of these services. Open Engineer tracks its own desktop release version separately from the upstream OpenCode version it is built on, and it keeps the same MIT license as that upstream project.
