Code Health Remediation Framework
When This Activates
This skill activates when:
-
Health scan shows issues to fix
-
User wants to clean up codebase
-
Removing dead code or duplicates
-
Addressing tech debt
Health Score Interpretation
Score Rating Action
90-100 Excellent Maintain current practices
75-89 Good Address minor issues opportunistically
60-74 Fair Schedule cleanup sprint
40-59 Poor Prioritize remediation
0-39 Critical Immediate attention required
Issue Categories
- Dead Code
Types:
-
unused_export
-
Exported but never imported elsewhere
-
orphan_file
-
File not imported by any other file
-
unused_function
-
Function defined but never called
Confidence Levels:
-
High - Static analysis confirms no references
-
Medium - May have dynamic references
-
Low - Could be used via string import or reflection
- Duplicates
Types:
-
Exact duplicates (identical code blocks)
-
Near duplicates (similar logic, different variables)
-
Pattern duplicates (same structure, different implementations)
- Security Issues
Types:
-
Hardcoded secrets
-
Unsafe eval/exec usage
-
SQL injection vulnerabilities
-
XSS vulnerabilities
- Performance Issues
Types:
-
N+1 queries
-
Missing indexes
-
Unbounded loops
-
Memory leaks
Safe Remediation Workflow
Before Removing Dead Code
Verify with search
Check for string references
grep -r "functionName" .
Check for dynamic imports
grep -r "import(" .
Check test coverage
-
Is the code tested directly?
-
Is it a test helper?
Check for side effects
-
Does it register listeners?
-
Does it modify global state?
Review git history
-
Why was it added?
-
Was it recently used?
Removal Strategy
High confidence dead code:
- Remove the code
- Run tests
- If tests pass, commit
Medium confidence:
- Add deprecation comment
- Log usage if called
- Remove after verification period
Low confidence:
- Don't remove automatically
- Flag for manual review
- Ask original author if available
Duplicate Consolidation
Steps
-
Identify the canonical location
-
Create shared utility if needed
-
Update all callers to use shared version
-
Remove duplicates
-
Run tests
Example
// Before: duplicated in 3 files const formatDate = (d) => d.toISOString().split('T')[0];
// After: single location // utils/dates.ts export const formatDate = (d: Date) => d.toISOString().split('T')[0];
Health Config (Ignore Rules)
Projects can configure ignore rules in health_config.json :
{ "ignore": { "dead_code": [ {"file": "types.ts", "reason": "Type exports used via declaration merging"}, {"pattern": ".stories.tsx", "reason": "Storybook files"} ], "duplicates": [ {"pattern": ".test.ts", "reason": "Test setup can be duplicated"} ] }, "exclude_dirs": ["mocks", "fixtures"] }
MCP Tools for Health
Get current health status
memory_health action=status project=gyst
Trigger a new scan
memory_health action=scan project=gyst
Search for specific issues
memory_query "unused exports in auth"
Prioritization Matrix
Issue Type Impact Effort Priority
Security (hardcoded secrets) Critical Low P0
Large orphan files Medium Low P1
Duplicate logic Medium Medium P2
Unused exports Low Low P3
Minor duplicates Low Low P4
