Kodo Analyzer Skill
Comprehensive codebase analysis methodology for existing projects.
Purpose
The Kodo Analyzer system provides systematic codebase analysis to:
- Infer and document existing features
- Identify gaps, bugs, and security issues
- Calculate health scores per category
- Generate actionable recommendations
- Track health trends over time
When to Use
- New project onboarding (existing codebase)
- Periodic health checks
- Pre-refactoring assessment
- Security audits
- Documentation generation
- Before major releases

Health Scoring
See references/health-scoring.md for detailed methodology.
| Category | Weight | Score Factors |
|---|---|---|
| Database | 15% | RLS, indexes, unused detection |
| API | 15% | Auth, errors, documentation |
| Frontend | 15% | A11y, states, performance |
| Dependencies | 10% | Freshness, security |
| Analytics | 10% | Coverage, consistency |
| Documentation | 10% | Coverage, accuracy |
| Security | 15% | Auth, validation, secrets |
| Performance | 10% | Queries, bundles, caching |
Issue Classification
See references/issue-categories.md for severity definitions.
- Critical: Security vulnerabilities, data loss risks
- High: Bugs, missing auth, accessibility failures
- Medium: Performance issues, code quality
- Low: Style inconsistencies, minor improvements
Workflow
Step 1: Initialize
kodo analyze # Standard analysis
kodo analyze --deep # Deep mode: extract full content + learnings from docs/
kodo analyze --deep --auto # Auto-accept all findings
Deep Mode (--deep): In addition to standard analysis, extracts learnings from documentation:
- Scans
docs/directory recursively - Extracts rules, decisions, tech-stack choices, workflows, domain terms, conventions
- Creates context entries in
.kodo/context-tree/ - Creates learnings in
.kodo/learnings/(grouped by category) - Assigns HIGH confidence to your design docs (
docs/plans/), MEDIUM to inherited docs
Step 2: Review Summary
Check overall health score and critical issues.
Step 3: Drill Down
Review individual category reports in ./docs/analysis/.
Step 4: Prioritize
Use the prioritization matrix:
- High Impact + Low Effort = Do First
- Critical issues = Immediate attention
Step 5: Track Progress
# Store in context for trend tracking
kodo curate --category analysis --title "Health Report $(date)"
Step 6: Re-analyze
Run periodic analyses to track improvement:
kodo analyze --quick # Weekly
kodo analyze # Monthly
Integration
Kodo Context Storage
Analysis results are stored in .kodo/context/analysis/:
# Query previous analyses
kodo query "health score"
kodo query "security issues"
kodo query "performance bottlenecks"
Feature Documentation
Analysis can infer features and populate ./docs/features/:
kodo analyze # Also generates feature docs
Configuration
Set analysis preferences in .kodo/config.json:
{
"analyzer": {
"analyzers": {
"database": { "enabled": true },
"api": { "enabled": true },
"frontend": { "enabled": true },
"dependencies": { "enabled": true },
"analytics": { "enabled": true },
"documentation": { "enabled": true },
"security": { "enabled": true },
"performance": { "enabled": true }
},
"output": {
"directory": "./docs/analysis",
"populateFeatureDocs": true
},
"thresholds": {
"critical": 50,
"warning": 70
}
}
}
Best Practices
- Run full analysis on new projects - Establish baseline
- Run quick analysis weekly - Catch regressions
- Fix critical issues immediately - Security first
- Review recommendations - Not all apply
- Track health trends - Compare over time
- Focus on high-impact fixes - Use prioritization matrix
