## Choose when

### Choose ThoughtSource if…

- ThoughtSource is primarily Jupyter Notebook; Agent-Reach is Python.
- Tags unique to ThoughtSource: dataset, jupyter notebook, machine-learning, natural-language-processing.
- Leaner open-issue backlog (15).

### Choose Agent-Reach if…

- Agent-Reach is primarily Python; ThoughtSource is Jupyter Notebook.
- Tags unique to Agent-Reach: agent-infrastructure, ai-agent, ai-search, automation.
- Also covers AI Agents, Developer Tools.

## When NOT to use ThoughtSource

- Last GitHub push was 572 days ago (dormant maintenance, Dec 16, 2024). Validate activity before betting a new project on ThoughtSource.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use Agent-Reach

- 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.
