Root cause and the exact fix — in 30 seconds. Add 2 lines of code.
Drop the Vorlo handler into your agent. It captures every tool call, input, output, latency and the model's reasoning — fire-and-forget, never slows your agent.
When a step fails, Vorlo translates the raw error into plain English: what broke, the root cause across steps, and a specific fix you can act on.
Mark a fix as "it worked" — or let Vorlo notice the error stopped recurring. The diagnosis becomes verified for everyone who hits it next.
Vorlo blocks or flags risky actions beforethey run — using the failures it has already seen. The bug doesn't happen twice.
A chronological walk through every step your agent took, with inputs, outputs and a latency waterfall.
Failures grouped by root cause, not by session — so you fix the pattern, not the symptom.
Per-tool success rate, p50/p99 latency, and live "degraded tool" alerts in the last 30 minutes.
Copy a clean diagnosis straight into your editor, your team chat, or an issue tracker.
Most tools show you what happened and where. Vorlo tells you why it failed and what to change.
Every confirmed fix is remembered and shared. Accuracy climbs with use — a moat a late copycat can't replay.
Every answer is tagged verified · likely · best-guess. We never present a guess as a fact.
Async, bounded, fail-open. If Vorlo is ever down, your agent runs exactly as before.
No more ToolError: 403. Get the actual reason your step failed, written for a human.
Confirmed once, served to everyone. Vorlo gets more accurate every time someone fixes a bug.
Block or require approval for risky actions before they execute — based on what's failed before.
Every tool call, the data that flowed between steps, the reasoning behind each decision, and a latency waterfall — so you can see exactly where it went wrong.
When a failing tool recovers, Vorlo marks the fix verified automatically — no clicks required.
Other tools tell you what your agent did and where it happened. Vorlo tells you exactly why it failed — and fixes it.
No. Observability tools show you traces and leave the diagnosis to you. Vorlo reads the trace and tells you the root cause in plain English, gives a specific fix, learns which fixes actually work, and then prevents the same failure from happening again.
Effectively zero. The SDK is fire-and-forget with a bounded queue — it never blocks your agent, and if Vorlo is unreachable your agent runs exactly as before. The LLM diagnosis happens server-side, off your critical path.
Common errors are matched instantly by a curated registry (high accuracy, no AI guessing). The long tail is diagnosed by an LLM with full step context, then improved by feedback. Every answer carries a confidence label — verified, likely, or best-guess — so you always know how much to trust it.
Each distinct failure is fingerprinted. When a developer confirms a fix — or Vorlo sees the error stop recurring — that diagnosis is promoted to "verified" and its fix is served to everyone who hits the same failure next. Accuracy compounds with usage.
