## Choose when

### Choose Instrukt if…

- Instrukt is primarily Python; caveman is JavaScript.
- License: Instrukt is AGPL-3.0, caveman is MIT.
- Tags unique to Instrukt: agent-executor, agents, containers, developer-tools.
- Also covers AI Agents.

### Choose caveman if…

- caveman is primarily JavaScript; Instrukt is Python.
- License: caveman is MIT, Instrukt is AGPL-3.0.
- Tags unique to caveman: anthropic, caveman, claude-code, prompt-engineering.
- When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content.

## When NOT to use Instrukt

- Last GitHub push was 424 days ago (dormant maintenance, May 14, 2025). Validate activity before betting a new project on Instrukt.
- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use caveman

- When requiring complex and detailed prompts that necessitate more nuanced expression beyond simple, 'caveman'-style sentences.
- For situations where adherence to formal or specific linguistic structures is mandatory for the task's success.
