pyagent-trace 0.2.0

Pattern-aware OpenTelemetry tracing for multi-agent LLM systems

pyagent-trace

Pattern-aware OpenTelemetry tracing for multi-agent LLM systems. Track costs, record interactions, debug with replay.

Install

pip install pyagent-trace              # Core (CostTracker, Recorder work without OTel)
pip install pyagent-trace[otel]        # With OpenTelemetry spans

Components

• CostTracker — Accumulate costs by pattern, agent, and model (no OTel required)
• Recorder — Record all messages + LLM responses to JSONL for replay/debug
• PatternSpanEmitter — Create OTel spans for pattern executions (requires OTel)
• traced_pattern / traced_agent — Decorators for automatic tracing (requires OTel)
• PyAgentAttributes — Custom pyagent.* attribute constants

Quick Example (no OTel required)

from pyagent_trace import CostTracker, Recorder

tracker = CostTracker()
tracker.record("debate", "bull_agent", "gpt-4o", 500, 200, 0.003)
print(f"Total: ${tracker.total_cost:.4f}")
print(f"By model: {tracker.by_model()}")

recorder = Recorder()
recorder.start("debate")
recorder.record_llm_call("bull", messages, "Bull case: ...")
recorder.end("Final decision")
recorder.save("traces/debug.jsonl")
