raindrop-strands 0.0.4

Raindrop integration for Strands Agents

raindrop-strands

Raindrop integration for Strands Agents (Python). Automatically captures agent invocations, model calls, tool usage, and token metrics via the Strands hook system.

Installation

pip install raindrop-strands strands-agents

strands-agents is a required dependency.

Quick Start

import os
from strands import Agent
from raindrop_strands import RaindropStrands

raindrop = RaindropStrands(
    api_key=os.environ.get("RAINDROP_API_KEY"),
    user_id="user_123",
    convo_id="session_456",
)

agent = Agent(
    model="us.amazon.nova-lite-v1:0",
    system_prompt="You are a helpful assistant.",
)

raindrop.handler.register_hooks(agent)

result = agent("What is the capital of France?")
print(result)

raindrop.flush()

Omitting api_key disables telemetry shipping (a warning is emitted) but does not crash your application.

Debug Mode

Enable verbose logging to troubleshoot telemetry issues:

raindrop = RaindropStrands(
    api_key=os.environ.get("RAINDROP_API_KEY"),
    debug=True,
)

Configuration

raindrop = RaindropStrands(
    api_key="rk_...",              # Optional: Raindrop API key
    user_id="user_123",            # Optional: associate events with a user
    convo_id="session_456",        # Optional: conversation/session ID
    tracing_enabled=True,          # Optional: enable OTEL-based tracing (default: True)
    bypass_otel_for_tools=True,    # Optional: bypass OTEL for tool spans (default: True)
    debug=False,                   # Optional: enable debug logging (default: False)
)

Factory Function

A create_raindrop_strands() factory function is also available for convenience:

from raindrop_strands import create_raindrop_strands

raindrop = create_raindrop_strands(api_key="rk_...")
agent = Agent(model="us.amazon.nova-lite-v1:0")
raindrop.handler.register_hooks(agent)
result = agent("Hello!")
raindrop.flush()

Identifying Users

raindrop.identify(
    user_id="user_123",
    traits={"plan": "pro", "email": "[e-mail]"},
)

Tracking Signals

Track user feedback or other signals on AI responses:

raindrop.track_signal(
    event_id="evt_...",
    name="thumbs_up",
    signal_type="feedback",
    sentiment="POSITIVE",
)

Flush & Shutdown

Always flush before your process exits to ensure all data is sent:

raindrop.flush()       # flush pending data
raindrop.shutdown()    # flush + release resources

What Gets Captured

• Agent invocations: input prompt, output text, model name
• Token usage: prompt tokens, completion tokens, and cached tokens (from Bedrock/Anthropic cacheReadInputTokens / cacheCreationInputTokens)
• Tool call spans: individual tool spans tracked via interaction.track_tool() with name, input, output, duration, and error
• Finish reason: stop_reason or finish_reason from model responses (e.g., end_turn, tool_use)
• Errors: error type and message captured in event properties
• Async support: preserved via Strands' hook system

API

RaindropStrands(api_key, user_id, convo_id, tracing_enabled, bypass_otel_for_tools, disable_auto_instrument, debug)

Option	Type	Default	Description
api_key	str | None	None	Raindrop API key (rk_...). Omit to disable telemetry
user_id	str | None	None	Associate all events with a user
convo_id	str | None	None	Group events into a conversation
tracing_enabled	bool	True	Enable OTEL-based tracing
bypass_otel_for_tools	bool	True	Bypass OTEL for tool spans
disable_auto_instrument	bool	True	Library auto-instrumentation is opt-in (see below)
debug	bool	False	Enable debug logging

Library auto-instrumentation is opt-in

As of 0.0.3, disable_auto_instrument defaults to True: the integration no longer lets Traceloop monkey-patch every LLM client library it recognizes in your process (including the botocore machinery Strands' default Bedrock provider drives). The hook handler captures input/output, token usage, model name, and tool calls directly from Strands hook events, so no library patching is needed for full dashboards.

If you specifically want LLM-call-level spans from library instrumentation and have verified compatibility in your environment, opt back in with disable_auto_instrument=False.

Properties:

• handler — RaindropEventHandler instance to register on agents

Methods:

• flush() — flush pending telemetry
• shutdown() — flush and release resources
• identify(user_id, traits) — identify a user with optional traits
• track_signal(event_id, name, ...) — track a signal event

Testing

cd packages/strands-python
pip install -e '.[dev]'
python -m pytest tests/ -v
