Our review

Repairs runtime failures in a sandboxed application by reading exact errors, checking env-dependent code, applying safe patterns that preserve fallback behavior, and verifying with build and secret scans.

Strengths

  • Focuses on root cause instead of masking errors.
  • Provides specific files and configs to inspect.
  • Emphasizes safe fallback patterns and no secret exposure.
  • Includes verification steps such as rebuild and secret scanning.

Limitations

  • Specific to the described Vibiz codebase structure and stack.
  • Assumes a Next.js, E2B sandbox, and deployment conventions.
  • Does not cover every possible runtime error.
When to use it

Use when the sandbox app fails to build, boot, render, authenticate, call AI routes, read offers, or deploy cleanly.

When not to use it

Do not use for feature development or when you need to add new capabilities.

Security analysis

Safe
Quality score90/100

The skill provides safe repair guidelines for a sandbox app, emphasizing preservation of security guards, avoidance of secret exposure, and using standard debugging tools. There are no instructions for destructive or exfiltrating actions.

Examples

Fix boot failure from missing Turso env vars
The app boots but the landing page shows a 500 and I see a Turso env var missing error in the console. Apply the runtime repair skill to fix it safely.
Make build tolerant of missing API key
The build fails because SAPIOM_API_KEY is absent during `npm run build`. Make it tolerate missing env keys without exposing secrets.
Repair auth routes after deploy
After deploying, auth routes fail. Follow the runtime repair skill to inspect auth.ts, middleware, and api-guard, and apply the safe pattern to preserve landing-page-only mode.

Vibiz Runtime Repair

Repair the real failure. Do not bypass platform contracts to make an error disappear.

Start here:

  • Read the exact error, terminal output, browser console, or failing route response.
  • Inspect the file named in the stack trace before changing adjacent code.
  • Check env-dependent code in src/lib/auth.ts, src/middleware.ts, src/lib/sapiom.ts, src/lib/api-guard.ts, and scripts/migrate.mjs.
  • Check sandbox boot behavior in e2b.toml and template build behavior in Dockerfile.

Safe repair patterns:

  • If auth is unavailable because Turso env vars are missing, preserve landing-page-only mode and existing guards.
  • If AI routes fail because SAPIOM_API_KEY is missing, keep server-only behavior and return a clear unavailable state.
  • If a user-supplied third-party integration truly requires a runtime key, put it in .env server-side and keep it out of browser-exposed NEXT_PUBLIC_* vars unless the key is designed to be public.
  • If offers are missing, preserve getSeededOffers() fallback behavior and do not fabricate seeded offers.
  • If Tailwind fails, fix class/config/CSS compatibility instead of removing whole sections.
  • If Next build fails from runtime-only env assumptions, make the code tolerate absent envs during build without exposing secrets or disabling production behavior.

Verification:

  • Run the failing command again after each targeted fix.
  • Run npm run build before considering runtime repairs complete.
  • Search for accidental secret exposure with rg -n "SECRET|TOKEN|API_KEY|STRIPE".
