Code Insights (code-insights)

Agents that identify code quality issues in Kotlin codebases, analysis is file-based.

Accidental complexity Analyser Agent

Accidental complexity is complexity introduced by the tools, frameworks, design or implementation choices rather than by the inherent problem being solved.

Usage: navigate to your project and run claude and type:

use accidental-complexity-analyser subagent to analyse all kotlin prod files in this project, please skip test files and configuration.

Output:

File	Description
accidental-complexity-findings.jsonl	Line-by-line findings with pattern IDs
accidental-complexity-report-[YYYY-MM-DD].md	Summary with top patterns and statistics

Security Vulnerabilities (security-vulnerabilities)

Fixes Dependabot security alerts in GitHub repositories.

export GITHUB_DEPENDABOT_PAT="your-token"  # needs dependabot-* scopes

Command	Description
/security-vulnerabilities:list-dependabot-alerts	List all open alerts
/security-vulnerabilities:fix-dependabot-alert 123	Fix a specific alert
/security-vulnerabilities:fix-all-dependabot-alerts	Fix all open alerts
