Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Critical code requirements checklist derived from actual build failures. Use before committing code or when troubleshooting compilation errors.Key capabilities
- →Check exception handling
- →Validate encoding
- →Verify brace matching
- →Compile code
How it works
It provides a checklist of common build pitfalls and coding standards to prevent compilation errors.
Inputs & outputs
When to use code-checklist
- →Pre-commit code validation
- →Troubleshooting compilation errors
- →Fixing common Java build issues

Exceptions and Constructors
- NEVER throw checked exceptions from constructors calling
super()— use factory methods or composition - ALWAYS wrap
parseInt/parseLong/new BigDecimal()in try-catch with defaults
Comments and Encoding
- NEVER use Unicode box-drawing characters (┌ ─ │) in Javadoc — use ASCII (+, -, |)
- NEVER nest
/* */comments inside Javadoc — use-instead
File Editing
- ALWAYS include complete method context when doing string replacements
- ALWAYS compile immediately after edits (
mvn clean compile) - Count
{and}— they must match after every edit
Common Error Solutions
| Error | Cause | Fix |
|---|---|---|
illegal start of expression | Missing closing } | Count braces, add missing ones |
unreported exception IOException | Checked exception in super() | Use factory method pattern |
String index out of range | Wrong substring indices | Use substring(start, start+length) |
NumberFormatException | Invalid numeric string | Wrap in try-catch with default |
class, interface, enum expected | Unicode in comments or corrupted file | Use ASCII only in comments |
Pre-Commit Sequence
mvn clean compile # Must succeed, zero errors
mvn package # Must create JAR
# If DataGenerator exists:
java -cp target/classes com.ibm.pl1ref.util.DataGenerator
java -cp target/psam-translation-0.1.0.jar com.ibm.pl1ref.Main
When not to use it
- →Using Unicode box-drawing characters in Javadoc
Prerequisites
Limitations
- →Requires ASCII only in comments
How it compares
It focuses on preventing specific, recurring build failures rather than general linting.
