Skill Detail

Quick brief
Use pytest-split when an agent needs to break a growing pytest suite into balanced groups based on historical run times. It fits CI tuning work where the problem is not test correctness but slow, uneven, or unpredictable lane completion.
How it works
What this skill actually does
Invoke this instead of running pytest normally when the agent must produce balanced shards and reduce end-to-end CI time without hand-curating test buckets. This is skill-shaped because the boundary is specific: timing-aware pytest sharding for CI. It is not a generic pytest plugin catalog entry or broad Python testing framework listing.
