name	autofix-skill
description	Comprehensive build error repair tool for C++, Rust, and Java projects using Soong, GN, Make, or CMake. Automatically fixes 30+ types of errors including headers, linking, APIs, and config.

AutoFix-Skill

This skill integrates the AutoFix engine to intelligently repair build failures in AOSP, OpenHarmony, and Linux Kernel environments.

capabilities

The skill operates by parsing build logs (or error strings), identifying the specific error type via regex/heuristics, and applying targeted fixes to the source code or build configuration files.

1. Symbol & Header Issues

• Missing Header: Adds #include <...> for standard and project headers.
• Undeclared Identifier: Import/include missing symbols.
• Namespace Errors: Fixes missing std:: or namespace scopes.
• Forward Declaration: Inserts forward decls to resolve circular deps.

2. Linkage & Dependencies

• Undefined Reference: Adds libraries to shared_libs/deps in Android.bp/BUILD.gn.
• Rust Crates: Adds missing rustlibs implies.
• Visibility: Resolves visibility restrictions between modules.
• Multiple Definitions: Removes duplicate sources or link dependencies.
• Vtable Issues: Identifies missing virtual function implementations.

3. API & Type Safety

• Signature Mismatch: Fixes function call arguments (too few/many).
• Type Conversion: Suggests static_cast, c_str(), etc.
• Const Correctness: Fixes const qualifier mismatches.
• Deprecated API: Updates legacy API calls to modern equivalents.
• Missing Override: Adds override keyword to virtual destructors/methods.

4. Build Configuration

• Syntax Errors: Fixes typos in Android.bp/BUILD.gn.
• Compiler Flags: Removes unsupported/illegal flags.
• Permissions: Fixes chmod +x for build scripts.
• Ninja Cache: Cleans dirty ninja build states.

Usage

Fix from Log File (Recommended)

cd /absolute/path/to/autofix_skill
PYTHONPATH=. python3 -m src.cli fix --log /path/to/build.log --root /path/to/project_root

Fix Single Error

cd /absolute/path/to/autofix_skill
PYTHONPATH=. python3 -m src.cli fix --error "fatal error: 'vector' file not found"

Scan for Patterns

cd /absolute/path/to/autofix_skill
PYTHONPATH=. python3 -m src.cli scan

Build Systems

• Android: Android.bp (Soong)
• OpenHarmony: BUILD.gn (GN)
• Linux Kernel: Kbuild/Makefile
• General C++: CMakeLists.txt
