Neatlogs Python Setup — Strands Agents

This project uses Strands Agents (strands.Agent). Strands self-instruments via native OpenTelemetry, and neatlogs.strands_hooks(agent) enriches those native spans with input/output so they render fully.

Core mechanism — init() + strands_hooks(agent)

1. neatlogs.init() registers the global tracer provider, so Strands' own OTel spans (invoke_agent, execute_tool, model chat calls) flow into neatlogs and the attribute mapper classifies them as AGENT / TOOL / LLM (with token usage).
2. neatlogs.strands_hooks(agent) is REQUIRED to capture prompt/response content. Strands records I/O as OTel span events (gen_ai.user.message, gen_ai.choice, …), which neatlogs doesn't render from events. strands_hooks() installs a hook on Strands' telemetry that copies that content onto the span as input.value/output.value — so LLM/TOOL spans show their actual input/output, not just tokens. Without it you get spans + tokens but empty I/O.

import neatlogs
neatlogs.init(api_key=os.getenv("NEATLOGS_API_KEY"), workflow_name="my-app")

from strands import Agent
agent = neatlogs.strands_hooks(Agent(model=model, tools=[...]))   # enables I/O capture
agent("Hello")

strands_hooks() does NOT create its own spans (Strands' native tracing stays the source of truth) and is idempotent — the hook installs once globally. Combine with @neatlogs.span / neatlogs.trace / neatlogs.log for your own orchestration — the native Strands spans nest under your manual spans.

Steps

1. Install → references/1-install.md
2. Add init() → references/2-add-init.md
3. Set environment variables → references/3-set-env.md
4. Wrap the agent with strands_hooks() + run it → references/4-run-agent.md
5. Add @span / trace / log to orchestration → references/5-spans-trace-log.md
6. Lifecycle (flush/shutdown) → references/6-flush-shutdown.md

Rules (apply to ALL steps)

• neatlogs.init() MUST run BEFORE importing strands so the tracer provider is registered before Strands reads it. load_dotenv() runs before init().
• Do NOT add instrumentations=[...] for Strands — init() + Strands' native OTel is the capture path.
• Wrap EVERY agent with agent = neatlogs.strands_hooks(agent) — REQUIRED for input/output content (not just tokens). It installs the I/O hook once (idempotent) and returns the same agent; it does NOT create extra spans.
• Strands ships BedrockModel; ensure AWS creds + region are set.
• Never hardcode keys/credentials. import neatlogs at module top level.
