agentobs-validate

Reference validation CLI and Python SDK for the AgentOBS event standard.

---

Overview

agentobs-validate validates JSON or JSONL event streams against the AgentOBS schema. It can be used as a CLI tool for CI pipelines or as a Python library for programmatic validation.

If an event stream passes validation, it is considered AgentOBS compliant.

---

Installation

pip install agentobs-validate

For development:

git clone https://github.com/veerarag1973/AgentOBSValidate.git
cd AgentOBSValidate
pip install -e ".[dev]"

---

Quick Start — CLI

# Validate a JSONL stream
agentobs-validate events.jsonl

# Validate a JSON array
agentobs-validate events.json

# JSON output for CI / downstream scripts
agentobs-validate events.jsonl --json

# Read from STDIN
cat events.jsonl | agentobs-validate

# OpenTelemetry compatibility: accept camelCase field names
agentobs-validate events.jsonl --otel

# Pin to a specific schema version
agentobs-validate events.jsonl --schema-version 0.1

# Cryptographic HMAC-SHA256 signature verification
agentobs-validate events.jsonl --key-file signing.key

# Export the AgentOBS event JSON Schema (Draft 2020-12)
agentobs-validate --export-schema > agentobs-schema.json

Quick Start — Python SDK

from agentobs_validate.validator.engine import validate_event, validate_stream

# Validate a single dict
result = validate_event(1, {

    "span_id": "00f067aa0ba902b7",
})
print(result.status)  # "pass"

# Validate a JSONL file
result = validate_stream(iter_events("events.jsonl"))
print(f"{result.valid}/{result.events_checked} valid")

# OTel mode + HMAC key
ctx = ValidationContext(otel_mode=True, key_bytes=open("signing.key", "rb").read().rstrip())
result = validate_stream(iter_events("events.jsonl"), ctx)
