What it can do
- Takes a design brief through planning, a simplified RStoic/SEP skeleton, block-by-block rigorous modelling and a whole-plant re-run, recording sources and changes at each step.
- Separate skills cover distillation set-up from DSTWU to RadFrac, heat-pump distillation, pressure paths, flowsheet error repair, kinetics documentation and component templates.
- An equipment backend sizes 17 equipment types and feeds real limits, such as exchanger or compressor staging, back into the model.
- Further skills cover Aspen EDR rating, AEPA equipment cost extraction and SW6 field mapping.
- A local stdio MCP server offers the knowledge search and equipment calculations, and a vendored copy of the ddtlxc001 aspen-mcp server can be started separately.
Limitations
- Written in Chinese, and aimed at Codex.
- Aspen operations need a local, licensed Aspen Plus on Windows; EDR and SW6 skills need those products too.
- The offline runtime was checked on CPython 3.14 for Windows AMD64; third-party reference data in the knowledge base keeps its own licences rather than MIT.
