## 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: deprecateComponent()
responsável: Dex (Builder)
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

# Deprecate Component - AIOS Developer Task

## Purpose
Mark framework components as deprecated with timeline management and migration path generation.

## Command Pattern
```
*deprecate-component <component-type> <component-name> [options]
```

## Parameters
- `component-type`: Type of component (agent, task, workflow, util)
- `component-name`: Name/ID of the component to deprecate
- `options`: Deprecation configuration and timeline

### Options
- `--removal-version <version>`: Target version for removal (default: next major)
- `--replacement <name>`: Replacement component name
- `--reason <text>`: Deprecation reason
- `--migration-guide <path>`: Path to migration guide
- `--immediate`: Mark for immediate deprecation warnings
- `--timeline <months>`: Deprecation timeline in months (default: 6)
- `--severity <level>`: Deprecation severity (low, medium, high, critical)

## Examples
```bash
# Deprecate an agent with replacement
*deprecate-component agent weather-fetcher --replacement weather-service --reason "Performance optimization" --timeline 3

# Deprecate a utility with migration guide
*deprecate-component util old-logger --replacement @aios/logger --migration-guide docs/migration/logger.md --severity high

# Immediate deprecation for security issue
*deprecate-component task insecure-parser --immediate --reason "Security vulnerability" --severity critical

# Deprecate workflow with custom removal version
*deprecate-component workflow legacy-processor --removal-version 3.0.0 --timeline 12
```

## Overview
The ${component.type} \`${component.name}\` has been deprecated and will be removed in version ${plan.removalVersion}.

## Reason for Deprecation
${plan.reason}

## Migration Steps
1. Replace usage of \`${component.name}\` with \`${plan.replacement}\`
2. Update any configuration references
3. Test the replacement functionality
4. Remove any deprecated imports/references

## Timeline
- Deprecated: ${new Date(plan.deprecationTimestamp).toLocaleDateString()}
- Removal planned: Version ${plan.removalVersion}
- Timeline: ${plan.timeline} months

## Need Help?
If you encounter issues during migration, please refer to the documentation or contact support.

## Validation Rules

### Input Validation
- Component type must be valid (agent, task, workflow, util)
- Component must exist in the framework
- Severity must be valid level
- Timeline must be positive number

### Safety Checks
- Warn if component has high usage
- Require confirmation for critical components
- Prevent accidental deprecation of core components

### Deprecation Requirements
- Must specify removal timeline
- Should provide replacement when available
- Must include deprecation reason
- Should generate migration artifacts

## Integration Points

### Deprecation Manager
- Records deprecation metadata
- Tracks deprecation timeline
- Manages scheduled tasks
- Provides deprecation status

### Usage Tracker
- Analyzes component usage across codebase
- Identifies dependent components
- Tracks usage patterns over time
- Provides impact analysis

### Migration Generator
- Creates migration guides
- Generates replacement suggestions
- Provides automated migration scripts
- Tracks migration progress

## Output Structure

### Success Response
```json
{
  "success": true,
  "deprecationId": "dep-1234567890-abc123",
  "component": {
    "type": "agent",
    "name": "weather-fetcher",
    "filePath": "/path/to/component"
  },
  "timeline": 6,
  "usageCount": 3,
  "migrationRequired": true
}
```

### Error Response
```json
{
  "success": false,
  "error": "Component not found: agent/invalid-name",
  "suggestions": ["weather-service", "weather-api"]
}
```

## Security Considerations
- Validate all file paths to prevent directory traversal
- Sanitize user input for deprecation reasons
- Require appropriate permissions for component modification
- Log all deprecation actions for audit trail
