Choose ospec if…

  • Tags unique to ospec: ai-coding-assistant, agentic-ai, agentic-coding, ai-workflow.
  • Also covers AI Agents.
  • Leaner open-issue backlog (0).

When NOT to use ospec

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

Choose caveman if…

  • Tags unique to caveman: caveman, tokens, anthropic, prompt-engineering.
  • When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content.
  • More GitHub stars (88k vs 559) - visibility, not fit.

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.
