llm-echo 0.5 accounts for tool calls and reasoning tokens in simulated usage
The llm-echo debug plugin now includes tool calls, system prompts, and reasoning tokens in its simulated usage counts. That makes it more useful for testing LLM integrations without making real model calls.
- What
- llm-echo is a debugging plugin for LLM that provides a model which echoes prompts without calling an LLM.
- How
- Version 0.5 updates simulated token usage to account for tool calls, system prompts, and reasoning tokens.
- Why it matters
- Engineers can test LLM integrations and usage reporting without invoking a real model.
