rewind-agent 0.5.0

Chrome DevTools for AI agents — record, inspect, fork, replay, diff.

rewind-agent

Python SDK for Rewind — the time-travel debugger for AI agents.

Record every LLM call. See the exact context window. Fork, fix, replay — without re-running.

Install

pip install rewind-agent

Requires the Rewind CLI for recording. Install with:

curl -fsSL https://raw.githubusercontent.com/agentoptics/rewind/main/install.sh | sh

Quick Start

import rewind_agent

# Auto-patches OpenAI/Anthropic clients to route through the Rewind proxy
rewind_agent.init()

# Your existing agent code runs unchanged — all LLM calls are recorded
client = openai.OpenAI()
client.chat.completions.create(model="gpt-4o", messages=[...])

Agent Hooks

Enrich recordings with semantic labels:

@rewind_agent.step("search")
def search(query: str) -> str:
    return client.chat.completions.create(...)

@rewind_agent.tool("calculator")
def calculate(a: float, b: float) -> float:
    return a + b

with rewind_agent.trace("analysis"):
    rewind_agent.annotate("confidence", 0.92)
    result = search("Tokyo population")

Framework Adapters

# LangGraph
graph = rewind_agent.wrap_langgraph(compiled_graph)

# CrewAI
crew = rewind_agent.wrap_crew(crew)
