However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; ai-reliability-copilot is TypeScript. - Tags unique to caveman: caveman, ai, tokens, claude-code. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose ai-reliability-copilot if… - ai-reliability-copilot is primarily TypeScript; caveman is JavaScript. - Tags unique to ai-reliability-copilot: incident-response, ai-sdk, deepseek, llm. - Also covers Vector Databases. - ai-reliability-copilot ships an MCP server manifest. ## 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. ## When NOT to use ai-reliability-copilot - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## Common questions ### What is the difference between caveman and ai-reliability-copilot? caveman: Reduce token usage with concise 'caveman'-style prompts.. ai-reliability-copilot: Turn a production incident into a structured 9-section LLM response (severity, root cause, mitigation, postmortem).
