python-performance SKILL.md skillA
python-performance from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add athola/claude-night-market/python-performance@git:20260902.4a35d69Pins git:20260902.4a35d69 in mdr.lock. Pin the fingerprint instead.

Profiles Python code for performance bottlenecks and memory issues. Use when Python code is slow or when profiling for optimization before a release.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Performance Optimization
Profiling and optimization patterns for Python code.
## Quick Start
```python
# Basic timing
import timeit
time = timeit.timeit("sum(range(1000000))", number=100)
print(f"Average: {time / 100:.6f}s")
```
**Verification:** Run the command with `--help` flag to verify availability.
## When To Use
- Identifying performance bottlenecks
- Reducing application latency
- Optimizing CPU-intensive operations
- Reducing memory consumption
- Profiling production applications
- Improving database query performance
## When NOT To Use
- Async concurrency - use python-async
instead
- CPU/GPU system monitoring - use conservation:cpu-gpu-performance
- Async concurrency - use python-async
instead
- CPU/GPU system monitoring - use conservation:cpu-gpu-performance
## Modules
This skill is organized into focused modules for progressive loading:
### [profiling-tools](modules/profiling-tools.md)
CPU profiling with cProfile, line profiling, memory profiling, and production profiling with py-spy. Essential for identifying where your code spends time and memory.
### [optimization-patterns](modules/optimization-patterns.md)

How to install
mdr add athola/claude-night-market/python-performance@sha256:cb9f11aa07e75c86The line at the top of this page pins the label git:20260902.4a35d69, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
