Qodana Inspect

Qodana Code Inspector

This skill runs Qodana static analysis on the current project and returns parsed inspection results in an easy-to-read format. It supports all JetBrains Qodana linters for comprehensive multi-language code analysis.

When to Use

Use this skill when you need to:

• Find code quality issues (unused code, redundant constructs, etc.)
• Detect potential bugs and problematic code patterns
• Check for JetBrains IDE inspections (IntelliJ IDEA, PyCharm, WebStorm, etc.)
• Get a list of issues to fix in the codebase
• Analyze code changes after modifications
• Perform language-specific static analysis across your tech stack

How to Use

Basic Usage

Run full project inspection (specify the appropriate linter for your project):

# Java/Kotlin project
bash .claude/skills/qodana-inspect/scripts/run-qodana.sh --linter qodana-jvm-community

# Python project
bash .claude/skills/qodana-inspect/scripts/run-qodana.sh --linter qodana-python-community

# TypeScript/JavaScript project
bash .claude/skills/qodana-inspect/scripts/run-qodana.sh --linter qodana-js

Incremental Analysis

Analyze only changes since a specific commit:

bash .claude/skills/qodana-inspect/scripts/run-qodana.sh --linter <linter-name> --diff-start <commit-hash>

Help

View all available linters and options:

bash .claude/skills/qodana-inspect/scripts/run-qodana.sh --help

Platform Fixes (Automatic)

The skill includes automatic platform-specific fixes for known Qodana issues. These fixes are applied automatically before analysis based on the selected linter.

PyCharm/Python Platform Fix

Issue: Qodana native mode for Python may fail to create jdk.table.xml, causing it to not recognize installed libraries from virtual environments (bug QD-11375).

Automatic Fix: When using qodana-python or qodana-python-community linters, the skill:

1. Detects if jdk.table.xml is missing in Qodana's config directory
2. Extracts Python SDK configuration from .idea/misc.xml
3. Automatically generates jdk.table.xml with proper paths to:
   • Virtual environment site-packages
   • Python standard library
   • Python DLLs

Result: Eliminates false positives like:

• PyTypeHintsInspection errors on valid PEP 604 union types (dict | None)
• PyClassHasNoInitInspection errors on @dataclass classes
• Import resolution errors for installed packages

This fix is transparent and requires no user configuration. If the project has .idea/misc.xml with a configured Python SDK, the fix applies automatically.

Future Platform Fixes

The architecture supports adding fixes for other platforms:

• IntelliJ IDEA (JVM projects)
• WebStorm (JavaScript/TypeScript)
• Rider (.NET projects)

Output Format

The script returns results grouped by file:

=== FILE: src/main/kotlin/example/Example.kt ===

[HIGH] UnusedSymbol
Location: line 45, column 13
Message: Variable 'unusedVar' is never used
Code:
val unusedVar = "test"

---

[MODERATE] NamingConvention
Location: line 52, column 9
Message: Property name should follow naming convention
Code:
private val MyProperty = "value"

=== FILE: src/main/kotlin/example/Another.kt ===
...

Severity Levels

• HIGH: Important issues (unused code, potential bugs, API problems)
• MODERATE: Style and convention issues
• INFO: Informational notices

Technical Details

• Mode: Native (no Docker required, uses --within-docker=false)
• Output: Parsed SARIF JSON format
• Results location:
  • Windows: ~/AppData/Local/JetBrains/Qodana/*/results/
  • macOS: ~/Library/Caches/JetBrains/Qodana/*/results/
  • Linux: ~/.cache/JetBrains/Qodana/*/results/

Requirements

• Qodana CLI must be installed (qodana command available)
• jq must be installed for JSON parsing
• Appropriate linter must be specified for the project's programming language

Notes

• Full scan typically takes 30 seconds to several minutes depending on project size
• Incremental scan with --diff-start takes longer (analyzes two project states)
• Results include exact line/column numbers and code snippets for context
• Script filters out Qodana progress messages, showing only final results
• Cross-platform support: Windows, macOS, Linux

Limitations

• Quick-Fix auto-correction is not available in Community Edition linters
• You must manually fix identified issues using Edit tool
• Use code context and snippets provided in output to understand and fix problems
• Ultimate linters (qodana-jvm, qodana-js, qodana-python, etc.) require a license
