neatlogs 1.3.9

A Python package for extracting and managing LLM logs to build a collaborative workspace

neatlogs

LLM observability for AI agents.
Instrument once. Inspect everything.

Agent failures don't throw exceptions — they produce wrong outputs, miss tool calls, or hallucinate.
Neatlogs captures every trace so you can see exactly what the model was given, what it decided, and what each step returned.

Installation

pip install neatlogs

Optional extras install the underlying LLM / framework libraries:

pip install "neatlogs[openai]"
pip install "neatlogs[crewai]"
pip install "neatlogs[langchain,langgraph]"
pip install "neatlogs[google-genai]"

Requires Python >= 3.10, < 3.14.

Quickstart

import neatlogs
from neatlogs import span

neatlogs.init(
    api_key="your-api-key",       # or NEATLOGS_API_KEY env var
    workflow_name="my-agent",
    instrumentations=["openai"],
)

# Import instrumented libraries AFTER init()
from openai import OpenAI


@span(kind="WORKFLOW", name="quickstart")
def main():
    client = OpenAI()
    return client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": "What is AI?"}],
    )


main()
neatlogs.flush()
neatlogs.shutdown()

Auto-instrumentation captures LLM calls, tools, and retrievals as child spans. Use @span(kind="WORKFLOW") on your main function or request handler so each run shows up as a top-level trace in the dashboard.

Call neatlogs.init() before importing any instrumented library.

For long-running servers (FastAPI, Celery workers), call init() once at startup and decorate each request handler with @span(kind="WORKFLOW"). Do not call flush() / shutdown() per request.

Integrate into your codebase (recommended)

The fastest way to add NeatLogs to an existing project is the official Agent Skill — it encodes import order, @span kinds, CrewAI prompt binding, and troubleshooting so your coding agent gets it right.

Repo: github.com/neatlogs/skills

npx skills add neatlogs/skills --skill "neatlogs-py"

For Cursor:

npx skills add neatlogs/skills --skill "neatlogs-py" --agent "cursor"

No Node.js? Ask in chat: "Install the NeatLogs AI skill from github.com/neatlogs/skills"

Example prompts once installed:

• "Add neatlogs tracing to my OpenAI calls"
• "Instrument my CrewAI agents with neatlogs"
• "Wrap my FastAPI handler so each request is a top-level trace"

Full install options: skills README

API reference: docs.neatlogs.com

Platform features

• Traces: Full span trees — LLM calls, tools, retrievals, reranking, guardrails — with inputs, outputs, tokens, cost, and latency.

• Timeline view: See which steps ran in parallel, where latency concentrated, and where the process was idle.

• AI assistant: Ask questions grounded in the actual span data for a trace.

• AI Search: Query traces in plain English without writing SQL.

• Detections: Rules that flag matching spans — regex, numeric conditions, PII, or model classifiers.

• Prompt management: Version prompts, promote labels, test in the Playground.

• Evals: Human review campaigns — select traces or spans (or auto-collect future ones via filters), send custom rating forms to assigned reviewers, and track batch progress and scores.

• Comments & voting: Pin notes to spans, @mention teammates, and thumbs-up/down vote outputs while debugging a trace.

Best practices

1. init() before LLM imports — auto-instrumentation patches libraries at import time.
2. Wrap script/server entry points in @span(kind="WORKFLOW") — each run gets a clear top-level trace in the dashboard.
3. Use auto-instrumentation first — only add more @span decorators for custom orchestration.
4. trace() for prompts and sessions — not as a wrapper around @span(kind="WORKFLOW").
5. workflow_name = feature name — put env/version/tech stack in tags=.
6. Scripts: flush() then shutdown() at exit. Servers: init() once, no per-request shutdown.
