Is your AI agent debugging legacy Java through logs?

It adds prints, reruns, reads the output, and guesses again — while the bug wins.

Give it a real debugger ↓

LegacyOrderService.java

// agent attempt #17

System.out.println(order);

System.out.println(discount);

System.out.println(context);

the printf loop

A loop that never converges.

Every rerun burns tokens. The value, caller or branch that actually broke stays hidden.

agent-debug.log

Adds print statements

Your code turns into telemetry.

Reruns the same path

Build, reproduce, copy, guess.

Burns context on guesses

Tokens rebuild what the IDE already knows.

Misses the real cause

The value, caller or branch stays hidden.

try explyt

An agent with native access to the IDEA debugger.

It drives the debugger, reads real runtime state, and reasons from facts — even in IDEA Community.

Variables

variables=live object state

callStack=full, walkable

breakpoints=set · step · resume

executionPath=traced, not guessed

temporary demo · Explyt vs. Cursor comparison coming soon

Same bug. Different access.

A text-first agent rebuilds runtime state from logs. Explyt asks IDEA directly.

text-first agent

print → rerun → parse → guess

explyt in idea

break → inspect → step → fix

resume ▸

Give Explyt one failing test.

Watch it break, inspect, and fix — then compare with the agent you use today.

What IDE-native debugging feels like.

What impressed me most is how well the agent understands the existing project. Its plans fit naturally into what is already built, even when I am working outside my usual tech stack.

LSP gives an agent coordinates; the full IDE gives it the project model. That native IDE context makes all the difference on real Java code.
