# learn-patterns

## Execution Modes

**Choose your execution mode:**

### 1. YOLO Mode - Fast, Autonomous (0-1 prompts)
- Autonomous decision making with logging
- Minimal user interaction
- **Best for:** Simple, deterministic tasks

### 2. Interactive Mode - Balanced, Educational (5-10 prompts) **[DEFAULT]**
- Explicit decision checkpoints
- Educational explanations
- **Best for:** Learning, complex decisions

### 3. Pre-Flight Planning - Comprehensive Upfront Planning
- Task analysis phase (identify all ambiguities)
- Zero ambiguity execution
- **Best for:** Ambiguous requirements, critical work

**Parameter:** `mode` (optional, default: `interactive`)

---

## Task Definition (AIOS Task Format V1.0)

```yaml
task: learnPatterns()
responsável: Uma (Empathizer)
responsavel_type: Agente
atomic_layer: Molecule

**Entrada:**
- campo: task
  tipo: string
  origem: User Input
  obrigatório: true
  validação: Must be registered task

- campo: parameters
  tipo: object
  origem: User Input
  obrigatório: false
  validação: Valid task parameters

- campo: mode
  tipo: string
  origem: User Input
  obrigatório: false
  validação: yolo|interactive|pre-flight

**Saída:**
- campo: execution_result
  tipo: object
  destino: Memory
  persistido: false

- campo: logs
  tipo: array
  destino: File (.ai/logs/*)
  persistido: true

- campo: state
  tipo: object
  destino: State management
  persistido: true
```

---

## Pre-Conditions

**Purpose:** Validate prerequisites BEFORE task execution (blocking)

**Checklist:**

```yaml
pre-conditions:
  - [ ] Task is registered; required parameters provided; dependencies met
    tipo: pre-condition
    blocker: true
    validação: |
      Check task is registered; required parameters provided; dependencies met
    error_message: "Pre-condition failed: Task is registered; required parameters provided; dependencies met"
```

---

## Post-Conditions

**Purpose:** Validate execution success AFTER task completes

**Checklist:**

```yaml
post-conditions:
  - [ ] Task completed; exit code 0; expected outputs created
    tipo: post-condition
    blocker: true
    validação: |
      Verify task completed; exit code 0; expected outputs created
    error_message: "Post-condition failed: Task completed; exit code 0; expected outputs created"
```

---

## Acceptance Criteria

**Purpose:** Definitive pass/fail criteria for task completion

**Checklist:**

```yaml
acceptance-criteria:
  - [ ] Task completed as expected; side effects documented
    tipo: acceptance-criterion
    blocker: true
    validação: |
      Assert task completed as expected; side effects documented
    error_message: "Acceptance criterion not met: Task completed as expected; side effects documented"
```

---

## Tools

**External/shared resources used by this task:**

- **Tool:** task-runner
  - **Purpose:** Task execution and orchestration
  - **Source:** .aios-core/core/task-runner.js

- **Tool:** logger
  - **Purpose:** Execution logging and error tracking
  - **Source:** .aios-core/utils/logger.js

---

## Scripts

**Agent-specific code for this task:**

- **Script:** execute-task.js
  - **Purpose:** Generic task execution wrapper
  - **Language:** JavaScript
  - **Location:** .aios-core/scripts/execute-task.js

---

## Error Handling

**Strategy:** retry

**Common Errors:**

1. **Error:** Task Not Found
   - **Cause:** Specified task not registered in system
   - **Resolution:** Verify task name and registration
   - **Recovery:** List available tasks, suggest similar

2. **Error:** Invalid Parameters
   - **Cause:** Task parameters do not match expected schema
   - **Resolution:** Validate parameters against task definition
   - **Recovery:** Provide parameter template, reject execution

3. **Error:** Execution Timeout
   - **Cause:** Task exceeds maximum execution time
   - **Resolution:** Optimize task or increase timeout
   - **Recovery:** Kill task, cleanup resources, log state

---

## Performance

**Expected Metrics:**

```yaml
duration_expected: 2-5 min (estimated)
cost_estimated: $0.001-0.003
token_usage: ~1,000-3,000 tokens
```

**Optimization Notes:**
- Parallelize independent operations; reuse atom results; implement early exits

# No checklists needed - analytical pattern learning task, no deliverables requiring validation

# Learn Patterns - AIOS Developer Task

## Purpose
Learn patterns from successful modifications to improve future meta-agent suggestions and automation.

## Command Pattern
```
*learn-patterns [options]
```

## Parameters
- `options`: Pattern learning configuration

### Options
- `--from-history <count>`: Learn from last N modifications (default: 50)
- `--type <types>`: Comma-separated pattern types to learn (code,structural,refactoring,dependency,performance)
- `--component <path>`: Learn patterns specific to a component
- `--threshold <value>`: Similarity threshold for pattern matching (0-1, default: 0.8)
- `--min-occurrences <count>`: Minimum occurrences before learning (default: 3)
- `--export <file>`: Export learned patterns to file
- `--import <file>`: Import patterns from file
- `--analyze`: Show pattern analysis and statistics
- `--reset`: Reset all learned patterns
- `--suggest <modification-id>`: Get pattern suggestions for a modification

## Examples
```bash
# Learn from recent modification history
*learn-patterns --from-history 100

# Learn specific pattern types
*learn-patterns --type code,refactoring --threshold 0.9

# Analyze patterns for a component
*learn-patterns --component aios-core/agents/developer.md --analyze

# Get suggestions for upcoming modification
*learn-patterns --suggest mod-123456 --type refactoring

# Export patterns for sharing
*learn-patterns --export patterns-export.json
```

## Pattern Types

### Code Transformation Patterns
- Variable renaming conventions
- Function extraction patterns
- Error handling additions
- Async/await conversions
- Code modernization patterns

### Structural Patterns
- Component organization changes
- Module restructuring
- Interface modifications
- Class hierarchy changes
- File organization patterns

### Refactoring Patterns
- Method extraction
- Class decomposition
- Interface segregation
- Dependency injection
- Code consolidation

### Dependency Patterns
- Package updates
- Import reorganization
- Dependency injection
- Service layer patterns
- API versioning

### Performance Patterns
- Caching implementations
- Query optimizations
- Lazy loading patterns
- Memory usage improvements
- Algorithm optimizations

## Learning Process

### Pattern Extraction
1. Analyze successful modifications
2. Extract change patterns using AST
3. Calculate pattern similarity
4. Group similar patterns
5. Build pattern templates

### Pattern Validation
1. Check minimum occurrences
2. Verify success rate
3. Validate consistency
4. Test applicability
5. Calculate confidence score

### Pattern Application
1. Match current context
2. Suggest relevant patterns
3. Provide application guide
4. Monitor application success
5. Update pattern metrics

## Integration Points

### Pattern Learner Utility
- Core pattern learning engine
- Pattern storage and retrieval
- Similarity calculations
- Suggestion generation

### Modification History
- Access to past modifications
- Success/failure tracking
- Component change history
- Impact analysis data

### Component Registry
- Component metadata
- Dependency information
- Usage patterns
- Performance metrics

## Security Considerations
- Validate pattern sources
- Prevent malicious patterns
- Audit pattern applications
- Secure pattern storage
- Control pattern sharing

## Best Practices
1. Learn from diverse modifications
2. Set appropriate thresholds
3. Regularly analyze patterns
4. Export valuable patterns
5. Monitor pattern effectiveness
6. Update patterns over time
7. Share patterns across teams
