## Choose when

### Choose spine-animation-ai if…

- spine-animation-ai is primarily Python; AirSim is C++.
- Tags unique to spine-animation-ai: 2d-animation, animation, animation-tool, character-rigging.
- Leaner open-issue backlog (0).

### Choose AirSim if…

- AirSim is primarily C++; spine-animation-ai is Python.
- Tags unique to AirSim: airsim, artificial-intelligence, autonomous-quadcoptor, autonomous-vehicles.
- Also covers AI Agents.

## When NOT to use AirSim

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
