# Bash Scripting Workflow

## Overview

Specialized workflow for creating robust, production-ready bash scripts with defensive programming patterns, comprehensive error handling, and automated testing.

## When to Use This Workflow

Use this workflow when:
- Creating automation scripts
- Writing system administration tools
- Building deployment scripts
- Developing backup solutions
- Creating CI/CD scripts

## Workflow Phases

### Phase 1: Script Design

#### Skills to Invoke
- `bash-pro` - Professional scripting
- `bash-defensive-patterns` - Defensive patterns

#### Actions
1. Define script purpose
2. Identify inputs/outputs
3. Plan error handling
4. Design logging strategy
5. Document requirements

#### Copy-Paste Prompts
```
Use @bash-pro to design production-ready bash script
```

### Phase 2: Script Structure

#### Skills to Invoke
- `bash-pro` - Script structure
- `bash-defensive-patterns` - Safety patterns

#### Actions
1. Add shebang and strict mode
2. Create usage function
3. Implement argument parsing
4. Set up logging
5. Add cleanup handlers

#### Copy-Paste Prompts
```
Use @bash-defensive-patterns to implement strict mode and error handling
```

### Phase 3: Core Implementation

#### Skills to Invoke
- `bash-linux` - Linux commands
- `linux-shell-scripting` - Shell scripting

#### Actions
1. Implement main functions
2. Add input validation
3. Create helper functions
4. Handle edge cases
5. Add progress indicators

#### Copy-Paste Prompts
```
Use @bash-linux to implement system commands
```

### Phase 4: Error Handling

#### Skills to Invoke
- `bash-defensive-patterns` - Error handling
- `error-handling-patterns` - Error patterns

#### Actions
1. Add trap handlers
2. Implement retry logic
3. Create error messages
4. Set up exit codes
5. Add rollback capability

#### Copy-Paste Prompts
```
Use @bash-defensive-patterns to add comprehensive error handling
```

### Phase 5: Logging

#### Skills to Invoke
- `bash-pro` - Logging patterns

#### Actions
1. Create logging function
2. Add log levels
3. Implement timestamps
4. Configure log rotation
5. Add debug mode

#### Copy-Paste Prompts
```
Use @bash-pro to implement structured logging
```

### Phase 6: Testing

#### Skills to Invoke
- `bats-testing-patterns` - Bats testing
- `shellcheck-configuration` - ShellCheck

#### Actions
1. Write Bats tests
2. Run ShellCheck
3. Test edge cases
4. Verify error handling
5. Test with different inputs

#### Copy-Paste Prompts
```
Use @bats-testing-patterns to write script tests
```

```
Use @shellcheck-configuration to lint bash script
```

### Phase 7: Documentation

#### Skills to Invoke
- `documentation-templates` - Documentation

#### Actions
1. Add script header
2. Document functions
3. Create usage examples
4. List dependencies
5. Add troubleshooting section

#### Copy-Paste Prompts
```
Use @documentation-templates to document bash script
```

## Script Template

```bash
#!/usr/bin/env bash
set -euo pipefail

readonly SCRIPT_NAME=$(basename "$0")
readonly SCRIPT_DIR=$(cd "$(dirname "$0")" && pwd)

log() { echo "[$(date '+%Y-%m-%d %H:%M:%S')] $*"; }
error() { log "ERROR: $*" >&2; exit 1; }

usage() { cat <<EOF
Usage: $SCRIPT_NAME [OPTIONS]
Options:
    -h, --help      Show help
    -v, --verbose   Verbose output
EOF
}

main() {
    log "Script started"
    # Implementation
    log "Script completed"
}

main "$@"
```

### Memory-First Protocol

Cache workflow configurations and automation patterns. Retrieve prior pipeline designs to avoid re-building similar flows from scratch.

```bash
# Check for prior workflow/automation context before starting
python3 execution/memory_manager.py auto --query "automation patterns and workflow configurations for Bash Scripting"
```

### Storing Results

After completing work, store workflow/automation decisions for future sessions:

```bash
python3 execution/memory_manager.py store \
  --content "Workflow: automated data pipeline with retry logic, dead-letter queue, and Slack alerts on failure" \
  --type technical --project <project> \
  --tags bash-scripting workflow
```

### Multi-Agent Collaboration

Share workflow state with other agents so they can trigger, monitor, or extend the automation.

```bash
python3 execution/cross_agent_context.py store \
  --agent "<your-agent>" \
  --action "Workflow automation deployed — pipeline processing 1000+ events/day with 99.9% success rate" \
  --project <project>
```

### Playbook Engine

Combine this skill with others using the Playbook Engine (`execution/workflow_engine.py`) for guided multi-step automation with progress tracking.
