Overview

Fix Compile Errors analyzes the current codebase to identify compilation failures and prescribes concrete fixes. It covers type mismatches, missing imports, syntax errors, undefined variables or functions, and configuration issues, delivering corrected code along with explanations to get the project compiling again.

How This Skill Works

The skill parses build logs, maps errors to root causes, and generates targeted fixes with updated code blocks. It also explains why each fix resolves the issue and validates by re-running the build.

When to Use It

• When you see type mismatches or casting errors in a statically typed language (TypeScript, Java, etc.).
• When the compiler reports missing imports or unresolved dependencies.
• When there are syntax errors or malformed code that block compilation.
• When the codebase has undefined variables or functions flagged by the compiler.
• When build configurations (e.g., webpack, Maven, Gradle, tsconfig) cause compilation failures.

Quick Start

1. Step 1: Run the project build to collect current compilation errors.
2. Step 2: Use the skill to map errors to root causes and generate fixes with corrected code.
3. Step 3: Apply the fixes and re-run the build until it completes without errors.

Best Practices

• Reproduce the exact build locally using the same commands and environment.
• Tackle errors in top-down order, starting from the first failure.
• Provide precise, minimal fixes with annotated code snippets.
• Explain each change and why it resolves the issue.
• Rebuild and run tests to verify all errors are resolved.

Example Use Cases

• Fix a TypeScript type mismatch by narrowing or adjusting types.
• Add a missing import to restore a symbol used by the compiler.
• Update a renamed function reference causing undefined symbol.
• Correct a syntax error such as a stray semicolon or misbalanced braces.
• Resolve a build config issue (webpack alias, tsconfig paths, or Maven/Gradle settings) that leads to module not found.
