What Sim CLI does

Sim CLI defines cross-solver rules for sim-cli workflows, including tool selection, input classification, acceptance checks, and escalation. Use it when coordinating solver runs and deciding whether to use sim or native commands.

Sim CLI is cataloged under AI Engineering on DirSkills. Sim CLI comes from a repository tagged abaqus, advanced-packaging, agent-skills, ai-agents and ansys.

Documentation

README

Excerpt

sim-cli

You are working in a sim-cli-enabled solver workflow. Use the sim runtime where it adds control and observability, and compose solver-native tools directly where they are the right primitive. This skill carries the cross-solver discipline — the rules that hold across sim-cli workflows, regardless of which solver you drive.

The solver's plugin skill is self-contained for solver-specific work: solver hard constraints, dependency chains, snippets, workflows, SDK/solver notes. It does not depend on loading this skill — but it should stay consistent with the discipline below. If a rule applies to more than one solver, it belongs here, not in a plugin skill.
