Buyer checklist
What to verify before adopting
- Does the project expose enough code and release history to evaluate maintenance risk?
- Does it focus on orchestration, tool execution, memory, evaluation, or deployment?
- Is recent shipping activity substantive or mostly dependency and packaging churn?
