PyPI: zizkadb-crewai 0.1.5 · requires zizkadb-sdk>=0.5.0

Self-hosted, open-source observability and causal debugging for CrewAI.

A CrewAI run is normally a black box: when the output is wrong, it's hard to see which task or agent caused it. zizkadb-crewai logs every step of a crew run to ZizkaDB with a parent_id link, so a run becomes a causal tree — and one call, db.why(), walks that tree back to the root cause.

It doesn't only show what happened; it explains why it happened.

CrewAI run ──▶ ZizkaDBCrewLogger ──▶ ZizkaDB (causal store) ──▶ db.why() / dashboard

Install

Both packages are published on PyPI — no git URLs needed:

pip install zizkadb-sdk zizkadb-crewai crewai

Usage

ZizkaDBCrewLogger logs the crew lifecycle. Events auto-chain through the logger's last_event_id, so you can omit parent_id to link each event to the previous one.

from zizkadb import ZizkaDB
from zizkadb_crewai import ZizkaDBCrewLogger

# OSS-first: default to a local self-hosted instance; pass api_key only for remote/cloud.
async with ZizkaDB(host="http://localhost:8000") as db:
    logger = ZizkaDBCrewLogger(db=db, agent="research-crew")

    await logger.log_kickoff(goal="Research causal logging for AI agents")
    result = await crew.kickoff_async()
    for task_output in result.tasks_output:                    # one causal node per task
        await logger.log_task(
            description=task_output.description,
            output=str(task_output.raw)[:2000],
        )
    await logger.log_output(str(result))

    # The payoff — explain WHY the crew produced its output:
    (await db.why(logger.last_event_id)).print()

db.why() reconstructs the chain:

crew_kickoff → crew_task (Researcher) → crew_task (Writer) → crew_output

Runnable example

A complete two-agent crew (Researcher → Writer) with the why() proof lives at examples/crewai-agent/. It targets a self-hosted ZizkaDB (http://localhost:8000) — no cloud signup required.
