farol-sdk 0.1.5

Agent observability for builders

farol-sdk

Agent observability for builders. Wrap a function with @trace, pass token counts on the run dict, and Farol syncs runs to your dashboard—cost anomalies, alerts, the lot.

usefarol.dev

Install

pip install farol-sdk

Sync to Supabase and email alerts need extras (zero required deps otherwise):

pip install 'farol-sdk[supabase,resend]'

Set environment variables: SUPABASE_URL, SUPABASE_KEY, optionally SUPABASE_SERVICE_KEY for writes + API key resolution; RESEND_API_KEY and ALERT_EMAIL for anomaly emails.

---

Usage

from farol import trace

@trace("research-agent", farol_key="frl_your_key_here", model="claude-3-5-haiku-latest")
def my_agent(task: str, *, run):
    run["input_tokens"] = 100
    run["output_tokens"] = 50
    return "done"

The wrapped function receives run with steps, token fields, and timing; Farol computes cost from cost_per_1k_tokens (default suits many providers—override as needed).
