Restructure marketplace for isolated plugin architecture

- Organize 62 plugins into isolated directories under plugins/
- Consolidate tools and workflows into commands/ following Anthropic conventions
- Update marketplace.json with isolated source paths for each plugin
- Revise README to reflect plugin-based structure and token efficiency
- Remove shared resource directories (agents/, tools/, workflows/)

Each plugin now contains only its specific agents and commands, enabling
granular installation and minimal token usage. Installing a single plugin
loads only its resources rather than the entire marketplace.

Structure: plugins/{plugin-name}/{agents/,commands/}

- **44 Development Tools** - Optimized utilities including project scaffolding, security scanning, test automation, and infrastructure setup - **44 Development Tools** - Optimized utilities including project scaffolding, security scanning, test automation, and infrastructure setup
### Version 1.1.0 Highlights ### Key Features
- **Marketplace Refactored**: 36 plugins → 62 focused plugins (+72% granularity) - **Granular Plugin Architecture**: 62 focused plugins optimized for minimal token usage
- **Tools Expanded**: 6 additional tools (test generation, component scaffolding, XSS scanning, project scaffolding for Python/TypeScript/Rust) - **Comprehensive Tooling**: 44 development tools including test generation, scaffolding, and security scanning
- **100% Agent Coverage**: All plugins have at least one agent - **100% Agent Coverage**: All plugins include specialized agents
- **Better Discoverability**: 23 clear categories with 1-6 plugins each - **Clear Organization**: 23 categories with 1-6 plugins each for easy discovery
- **Optimized Architecture**: Average 3.4 components per plugin (follows Anthropic's 2-8 pattern) - **Efficient Design**: Average 3.4 components per plugin (follows Anthropic's 2-8 pattern)
### How It Works
Each plugin is completely isolated with its own agents and commands:
- **Install only what you need** - Each plugin loads only its specific agents and tools
- **Minimal token usage** - No unnecessary resources loaded into context
- **Mix and match** - Compose multiple plugins for complex workflows
- **Clear boundaries** - Each plugin has a single, focused purpose
**Example**: Installing `python-development` loads only 3 Python agents and 1 scaffolding tool (~300 tokens), not the entire marketplace.
## Installation ## Installation
### Step 1: Add the Marketplace
Add this marketplace to Claude Code: Add this marketplace to Claude Code:
```bash ```bash
/plugin marketplace add wshobson/agents /plugin marketplace add wshobson/agents
``` ```
Then browse and install plugins using: This makes all 62 plugins available for installation, but **does not load any agents or tools** into your context.
### Step 2: Install Specific Plugins
Browse available plugins:
```bash ```bash
/plugin /plugin
``` ```
Install only the plugins you need:
```bash
/plugin install python-development
/plugin install backend-development
```
Each installed plugin loads **only its specific agents and commands** into Claude's context.

def validate(self, data): pass
class UserRepository:
def save(self, user): pass
class EmailService:
def send_welcome_email(self, user): pass
class UserActivityLogger:
def log_creation(self, user): pass
class UserService:
def __init__(self, validator, repository, email_service, logger):
self.validator = validator
self.repository = repository
self.email_service = email_service
self.logger = logger
def create_user(self, data):
self.validator.validate(data)
user = self.repository.save(data)
self.email_service.send_welcome_email(user)
self.logger.log_creation(user)
return user
```
**Open/Closed Principle (OCP)**
```python
# BEFORE: Modification required for new discount types

# More logic
pass
# AFTER: Open for extension, closed for modification
from abc import ABC, abstractmethod
class DiscountStrategy(ABC):
@abstractmethod
def calculate(self, order): pass
class PercentageDiscount(DiscountStrategy):
def __init__(self, percentage):
self.percentage = percentage
def calculate(self, order):
return order.total * self.percentage
class FixedDiscount(DiscountStrategy):
def __init__(self, amount):
self.amount = amount
def calculate(self, order):

return order.total * 0.05
class DiscountCalculator:
def calculate(self, order, strategy: DiscountStrategy):

```
**Liskov Substitution Principle (LSP)**
```typescript
// BEFORE: Violates LSP - Square changes Rectangle behavior
class Rectangle {
constructor(protected width: number, protected height: number) {}
setWidth(width: number) { this.width = width; }
setHeight(height: number) { this.height = height; }
area(): number { return this.width * this.height; }
}
class Square extends Rectangle {
setWidth(width: number) {
this.width = width;
this.height = width; // Breaks LSP
}
setHeight(height: number) {
this.width = height;
this.height = height; // Breaks LSP
}
}
// AFTER: Proper abstraction respects LSP
interface Shape {
area(): number;
}
class Rectangle implements Shape {
constructor(private width: number, private height: number) {}
area(): number { return this.width * this.height; }
}
class Square implements Shape {
constructor(private side: number) {}
area(): number { return this.side * this.side; }
}
```
**Interface Segregation Principle (ISP)**
```java
// BEFORE: Fat interface forces unnecessary implementations
interface Worker {
void work();
void eat();
void sleep();
}
class Robot implements Worker {
public void work() { /* work */ }
public void eat() { /* robots don't eat! */ }
public void sleep() { /* robots don't sleep! */ }
}
// AFTER: Segregated interfaces
interface Workable {
void work();
}
interface Eatable {
void eat();
}
interface Sleepable {
void sleep();
}
class Human implements Workable, Eatable, Sleepable {
public void work() { /* work */ }
public void eat() { /* eat */ }
public void sleep() { /* sleep */ }
}
class Robot implements Workable {
public void work() { /* work */ }
}
```
**Dependency Inversion Principle (DIP)**
```go
// BEFORE: High-level module depends on low-level module
type MySQLDatabase struct{}
func (db *MySQLDatabase) Save(data string) {}
type UserService struct {
db *MySQLDatabase // Tight coupling
}
func (s *UserService) CreateUser(name string) {
s.db.Save(name)
}
// AFTER: Both depend on abstraction
type Database interface {
Save(data string)
}
type MySQLDatabase struct{}
func (db *MySQLDatabase) Save(data string) {}
type PostgresDatabase struct{}
func (db *PostgresDatabase) Save(data string) {}
type UserService struct {
db Database // Depends on abstraction
}
func NewUserService(db Database) *UserService {
return &UserService{db: db}
}
func (s *UserService) CreateUser(name string) {
s.db.Save(name)
}
```

### 5. Decision Frameworks
**Code Quality Metrics Interpretation Matrix**
| Metric | Good | Warning | Critical | Action |
|--------|------|---------|----------|--------|
| Cyclomatic Complexity | <10 | 10-15 | >15 | Split into smaller methods |
| Method Lines | <20 | 20-50 | >50 | Extract methods, apply SRP |
| Class Lines | <200 | 200-500 | >500 | Decompose into multiple classes |
| Test Coverage | >80% | 60-80% | <60% | Add unit tests immediately |
| Code Duplication | <3% | 3-5% | >5% | Extract common code |
| Comment Ratio | 10-30% | <10% or >50% | N/A | Improve naming or reduce noise |
| Dependency Count | <5 | 5-10 | >10 | Apply DIP, use facades |
**Refactoring ROI Analysis**
```
Priority = (Business Value × Technical Debt) / (Effort × Risk)
Business Value (1-10):
- Critical path code: 10

- Full tests, loose coupling: 2
```
**Technical Debt Prioritization Decision Tree**
```
Is it causing production bugs?
├─ YES → Priority: CRITICAL (Fix immediately)
└─ NO → Is it blocking new features?
├─ YES → Priority: HIGH (Schedule this sprint)
└─ NO → Is it frequently modified?

```
### 6. Modern Code Quality Practices (2024-2025)
**AI-Assisted Code Review Integration**
```yaml
# .github/workflows/ai-review.yml
name: AI Code Review

```
**Static Analysis Toolchain**
```python
# pyproject.toml
[tool.ruff]
line-length = 100
select = [
"E", # pycodestyle errors
"W", # pycodestyle warnings
"F", # pyflakes
"I", # isort

warn_unused_ignores = true
[tool.coverage]
fail_under = 80
```
```javascript
// .eslintrc.json
{
"extends": [
"eslint:recommended",
"plugin:@typescript-eslint/recommended-type-checked",
"plugin:sonarjs/recommended",
"plugin:security/recommended"
],
"plugins": ["sonarjs", "security", "no-loops"],
"rules": {

"max-params": ["error", 3],
"no-loops/no-loops": "warn",
"sonarjs/cognitive-complexity": ["error", 15]
}
}
```
**Automated Refactoring Suggestions**
```python
# Use Sourcery for automatic refactoring suggestions
# sourcery.yaml
rules:
- id: convert-to-list-comprehension
- id: merge-duplicate-blocks
- id: use-named-expression
- id: inline-immediately-returned-variable
# Example: Sourcery will suggest
# BEFORE
result = []
for item in items:
if item.is_active:
result.append(item.name)
# AFTER (auto-suggested)
result = [item.name for item in items if item.is_active]
```
**Code Quality Dashboard Configuration**
```yaml
# sonar-project.properties
sonar.projectKey=my-project
sonar.sources=src
sonar.tests=tests
sonar.coverage.exclusions=**/*_test.py,**/test_*.py
sonar.python.coverage.reportPaths=coverage.xml
# Quality Gates
sonar.qualitygate.wait=true
sonar.qualitygate.timeout=300
# Thresholds
sonar.coverage.threshold=80
sonar.duplications.threshold=3
sonar.maintainability.rating=A
sonar.reliability.rating=A
sonar.security.rating=A
```
**Security-Focused Refactoring**
```python
# Use Semgrep for security-aware refactoring
# .semgrep.yml
rules:
- id: sql-injection-risk
pattern: execute($QUERY)
message: Potential SQL injection
severity: ERROR
fix: Use parameterized queries
- id: hardcoded-secrets
pattern: password = "..."
message: Hardcoded password detected
severity: ERROR
fix: Use environment variables or secret manager
# CodeQL security analysis
# .github/workflows/codeql.yml
- uses: github/codeql-action/analyze@v3
with:
category: "/language:python"
queries: security-extended,security-and-quality
```
### 7. Refactored Implementation
Provide the complete refactored code with:
**Clean Code Principles**
- Meaningful names (searchable, pronounceable, no abbreviations)
- Functions do one thing well
- No side effects
- Consistent abstraction levels
- DRY (Don't Repeat Yourself)
- YAGNI (You Aren't Gonna Need It)
**Error Handling**
```python
# Use specific exceptions
class OrderValidationError(Exception):
pass
class InsufficientInventoryError(Exception):
pass
# Fail fast with clear messages
def validate_order(order):
if not order.items:
raise OrderValidationError("Order must contain at least one item")
for item in order.items:
if item.quantity <= 0:
raise OrderValidationError(f"Invalid quantity for {item.name}")
```
**Documentation**
```python
def calculate_discount(order: Order, customer: Customer) -> Decimal:
"""
Calculate the total discount for an order based on customer tier and order value.
Args:
order: The order to calculate discount for
customer: The customer making the order
Returns:
The discount amount as a Decimal
Raises:
ValueError: If order total is negative
"""
```
### 8. Testing Strategy
Generate comprehensive tests for the refactored code:
**Unit Tests**
```python
class TestOrderProcessor:
def test_validate_order_empty_items(self):
order = Order(items=[])
with pytest.raises(OrderValidationError):
validate_order(order)
def test_calculate_discount_vip_customer(self):
order = create_test_order(total=1000)
customer = Customer(tier="VIP")
discount = calculate_discount(order, customer)
assert discount == Decimal("100.00") # 10% VIP discount
```
**Test Coverage**
- All public methods tested
- Edge cases covered
- Error conditions verified
- Performance benchmarks included
### 9. Before/After Comparison
Provide clear comparisons showing improvements:
**Metrics**
- Cyclomatic complexity reduction
- Lines of code per method
- Test coverage increase
- Performance improvements
**Example**
```
Before:
- processData(): 150 lines, complexity: 25
- 0% test coverage
- 3 responsibilities mixed
After:
- validateInput(): 20 lines, complexity: 4
- transformData(): 25 lines, complexity: 5
- saveResults(): 15 lines, complexity: 3
- 95% test coverage
- Clear separation of concerns
```
### 10. Migration Guide
If breaking changes are introduced:
**Step-by-Step Migration**
1. Install new dependencies
2. Update import statements
3. Replace deprecated methods
4. Run migration scripts
5. Execute test suite
**Backward Compatibility**
```python
# Temporary adapter for smooth migration
class LegacyOrderProcessor:
def __init__(self):
self.processor = OrderProcessor()
def process(self, order_data):
# Convert legacy format
order = Order.from_legacy(order_data)
return self.processor.process(order)
```
### 11. Performance Optimizations
Include specific optimizations:
**Algorithm Improvements**
```python
# Before: O(n²)
for item in items:
for other in items:
if item.id == other.id:
# process
# After: O(n)
item_map = {item.id: item for item in items}
for item_id, item in item_map.items():
# process
```
**Caching Strategy**
```python
from functools import lru_cache
@lru_cache(maxsize=128)
def calculate_expensive_metric(data_id: str) -> float:
# Expensive calculation cached
return result
```
### 12. Code Quality Checklist
Ensure the refactored code meets these criteria:
- [ ] All methods < 20 lines
- [ ] All classes < 200 lines
- [ ] No method has > 3 parameters
- [ ] Cyclomatic complexity < 10
- [ ] No nested loops > 2 levels

```
Debt Item: No integration tests for payment flow
Bug Rate: 3 production bugs/month
Average Bug Cost:
- Investigation: 4 hours
- Fix: 2 hours
- Testing: 2 hours

'architectural_decisions',
'technology_stack',
'recent_agent_work',
'known_issues'
]
prioritized_components = prioritize_components(context_components)
restored_context = {}
current_tokens = 0
for component in prioritized_components:
component_tokens = estimate_tokens(component)
if current_tokens + component_tokens <= token_budget:
restored_context[component] = load_component(component)
current_tokens += component_tokens
return restored_context
```
