Your AI fixed the bug.Now there are three more.

Syncause shows your AI agent what's actually happening at runtime — stack trace, variables, logs, errors — so it fixes the real problem, not just the surface.

Debug Skill for AI Agents

Plug Syncause into the workflow you already have. Let your agent understand what happened before it patches.

Describe the bug

Tell the agent what failed, what behavior looks wrong, or where the system breaks.

Gather runtime facts

Syncause gives the agent access to execution-time evidence before it starts patching.

Fix from evidence

The agent works from what actually happened, making root-cause repair more likely.

function processWebhook(payload) {

const user = db.find(payload.userId);

const settings = user.getSettings();

if (settings.notify) {

sendEmail(user.email);

}

TypeError: Cannot read properties of null

AI Symptom Patch

Seeing only static code, AI guesses settings is null and masks the crash:

- if (settings.notify)
+ if (settings && settings.notify)

Variablepayload

{ userId: "usr_9x" }

Database Resultuser

{ id: "us_9x",
status: "deleted" }

AI Root Cause Fix

Syncause reveals the user is deleted. The correct fix is to handle deleted users, not just null check settings.

+ if (user.status === 'deleted') return;

Better root-cause fixing, not just better patching

On the industry-standard SWE-bench Verified benchmark, adding Runtime Facts helped fix 30 additional hard cases beyond the baseline — raising the theoretical combined resolve rate from 77.4% to 83.4%.

Root Cause

Fix the root cause, not just the symptom

When AI only sees the surface error, it often patches the wrong layer. Syncause helps it work from the actual execution path behind the failure.

Side Effects

Stop one fix from breaking something else

A shallow patch can silence one error while introducing another. Runtime facts make it easier to see side effects before and after the fix.

Debug Loop

Get out of the debug loop

Fix, test, fail, retry. When the root cause is unclear, AI and developers waste cycles chasing symptoms. Syncause shortens that loop with real runtime evidence.

How It Works

You describe the bug.Syncause does the rest.

Most agents jump straight to patching. Syncause slows them down first - making sure they're debugging the right failure, tracing the real execution path, and verifying the fix actually worked. You get fewer patches, and more fixes that stick.

Validate the failure

You describe the bug. Syncause confirms the agent is looking at the right problem, not a false positive or unrelated error.

Trace the root cause

Runtime facts — stack traces, variable states, execution paths — narrow the search from your whole codebase to the exact failure point.

Verify the fix

Before trusting the patch, Syncause compares runtime behavior before and after. Regressions and side effects get caught here, not in production.

Also available

Need a more hands-on workflow?

The IDE Extension is available for developers who want to inspect runtime facts directly in the editor, validate the agent's reasoning, or work through debugging manually.
