## Choose when

### Choose agent-prism if…

- agent-prism is primarily TypeScript; caveman is JavaScript.
- Tags unique to agent-prism: ai-agents, ai-monitoring, component-library, developer-tools.
- Also covers AI Agents.

### Choose caveman if…

- caveman is primarily JavaScript; agent-prism is TypeScript.
- Tags unique to caveman: ai, anthropic, caveman, claude code.
- 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 agent-prism

- 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.
