cfd-code-mod (alias)

This skill is a thin alias for cfd-skills/cfd-code-modify/SKILL.md. The full ARIS/DS-style self-contained recipe — including the OPENFOAM 10 LITERATURE CHANGE AGENT v2 protocol embedded verbatim, the wmake compile-fix loop, and the smoke-test recipe — lives there.

Why an alias?

After the Nov 2026 ARIS/DS-style refactor, all recipe content moved to cfd-skills/. CLAUDE.md routing for "implement / modify / viscosity model / Bingham / power-law / Carreau / source term / fvOption" historically pointed here, so this file remains for backward compatibility.

Do this

1. Open cfd-skills/cfd-code-modify/SKILL.md.
2. Follow Steps 1–7 there: build payload → resolve OpenFOAM API grounding → run the LITERATURE CHANGE AGENT (LLM call with the full v2 protocol embedded) → compile → compile-fix loop → smoke-test → write build_result.json.

Hard rules (preserved from the original skills/cfd-code-mod)

• Never edit $WM_PROJECT_DIR, $FOAM_SRC, or any OpenFOAM installation/source directory.
• All custom code lives in <case_path>/customModels/<ClassName>/.
• Compile case-locally with wmake libso. Link via controlDict.libs and one activation dictionary (constant/momentumTransport, constant/fvModels, or fallback constant/turbulenceProperties).
• One coherent in-family modification per invocation. Out-of-scope requests (new transported variables, solver edits, BC framework changes, multi-region, multi-physics outside kinematic viscosity) → return UNSUPPORTED.

Cross-link

• Standard CFD research after a code mod → continue from Stage 2 of cfd-skills/cfd-pipeline/SKILL.md (general path), with the mesh gate then running against the modified physics group.
• For OED of custom turbulence models, the code-mod is invoked inside cfd-skills/cfd-open-discovery/SKILL.md's discovery loop, once per candidate.
