Build Cython Extensions
This skill provides guidance for building Cython extensions and resolving compatibility issues, with particular focus on numpy version compatibility problems.
When to Use This Skill
- Building or compiling Cython extensions (
.pyxfiles) - Fixing numpy compatibility issues in Cython code
- Migrating Cython projects to work with numpy 2.0+
- Resolving deprecated numpy type errors (
np.int,np.float,np.bool, etc.) - Troubleshooting Cython compilation failures
Key File Types to Examine
When working with Cython projects, always examine ALL relevant file types:
| Extension | Description | Must Check |
|---|---|---|
.pyx |
Cython implementation files | Critical - Often contain numpy calls |

127portfolio-optimization
Guidance for implementing high-performance portfolio optimization using Python C extensions. This skill applies when tasks require optimizing financial computations (matrix operations, covariance calculations, portfolio risk metrics) by implementing C extensions for Python. Use when performance speedup requirements exist (e.g., 1.2x or greater) and the task involves numerical computations on large datasets (thousands of assets).
