Source Maps
SkillDev toolsSource Maps is a skill for AI agents that helps with generating and consuming source maps for debugging compiled code. It lets the agent trace minified or transpiled output back to the original source files. This is useful when you need to find where a bug actually lives in code that has been built or bundled.

Details
Instructions available. Your AI can read the instructions. Execution depends on the setup they require.
Account requirements not reviewed. Check the skill instructions before use; Ahel provides instructions and does not run this skill.
No other account needed.
Have a project with compiled or bundled code that needs debugging.
What your AI can do with it
- Generate source maps for compiled or bundled code
- Consume existing source maps to map errors to original files
- Trace minified stack traces back to original source locations
- Verify performance bottlenecks in DevTools or Lighthouse before suggesting fixes
Getting started
- Have a project with compiled or bundled code that needs debugging.
- Add the skill to your agent's available skills or configuration.
- Point the agent at the build output and its source map files.
- Ask the agent to trace a specific error or slow load back to the original source.
What this skill tells your AI
The instructions your AI receives, as published by a5c-ai/babysitter in library/specializations/programming-languages/skills/source-maps/SKILL.md and read by Ahel’s review.
Source maps are essential for debugging production issues effectively without compromising the performance benefits of minification.
Quick Reference
- Generate source maps to map minified code back to original source
- Upload source maps to error tracking services (e.g., Sentry) instead of serving them publicly
- Ensure source maps are correctly linked in your build process
Check
Verify if the project's build process generates source maps and if they are being correctly handled for production debugging.
Fix
Update the build configuration to generate source maps and integrate with an error tracking service for secure production debugging.
Explain
Explain how source maps enable developers to debug original source code when only minified code is running in the browser.
Code Review
Review the routes, assets, and loading behavior that affect Provide source maps for production debugging. Flag exact files, requests, or rendering steps that add unnecessary network, CPU, or layout cost, and describe the measurement method used to confirm the issue.

Questions
- Does this skill help audit slow page loads?
- Yes. It helps verify bottlenecks in DevTools or Lighthouse before suggesting fixes, so the agent can confirm what is actually slow.
- What do I need before using this skill?
- You need compiled or bundled code and its source map files, plus the skill added to your agent's configuration.
- Does it work with minified JavaScript?
- Yes. It can trace minified stack traces back to original source locations when source maps are available.
