The AI-era grade
AI familiarity: low
The project or its current major version postdates common model training cutoffs — expect agents to generate outdated or invented APIs. Verify everything.
This grade is the maintainer’s dated judgment about mainstream model training data — not a benchmark result. Re-graded on major releases. The grading rules live in the repository’s curation policy.
