AI root cause analysis for production issues
Debug the issue behind the stack trace.
StackSleuth finds the likely root cause behind stack traces using logs, repo structure, code snippets, and recent commits.

The debugging gap
Production incidents do not fail in tidy folders.
Logs are noisy
Stack traces rarely explain which repo path or commit matters first.
Context is scattered
Runtime errors, GitHub history, and code snippets live in separate tools.
Fixes need judgment
Teams need a clear first remediation step without false certainty.
How it works
From stack trace to focused remediation path.
Paste incident context
Add logs, repository URL, and what changed recently.
Rank likely files
StackSleuth scans repo structure and ranks the paths most worth opening.
Correlate evidence
Code snippets, commits, and stack frames become a single diagnosis.
Ship the fix prompt
Copy a concise remediation brief into Codex, Copilot, Jira, or Slack.
Mock report
Built for the first three minutes of an incident.
The report opens with the decision-ready answer, then keeps the evidence below for engineers who need to verify every assumption.
Likely Root Cause
The request payload is being destructured before schema validation.

Suggested Fix

- Ranked route handler first
- Recent commit touched validation
- Stack frame matches request boundary
