What it can do

Has the agent plan the blocks, compounds and property package first, and ask for any missing feed, pump, exchanger or column specification instead of inventing one.
Gives the tool order and port numbers for the `dwsim_*` tools of DWSIM 10's MCP server, including workarounds such as setting feed flow in a separate call after the composition.
Runs the flowsheet check and degrees-of-freedom check before solving, then confirms mass balance and plausible temperatures and reports a stream table and key unit results.
Saves the case as a `.dwxmz` file with a PNG of the diagram, and covers what-if comparisons through scenario snapshots.

Limitations

Needs the DWSIM 10 MCP server (`dwsim-mcp`), which the repository's dev container includes; outside it you install the server's Linux .deb from the DWSIM 10 releases.
Save paths assume the dev container's `/workspace` folder.
Sits in a repository of DWSIM automation exercises, not a standalone skill package.

Open the repository in its dev container (or install the dwsim-mcp .deb from the DWSIM 10 releases), start Claude Code in the repository and approve the project's dwsim server; the skill in .claude/skills/build-flowsheet/SKILL.md is picked up from the project.
