Terminal Basics

What is a Terminal?

In CAI TUI, a terminal is an independent execution environment where: - A single agent processes user prompts - Conversation history is maintained separately - Model selection can be configured independently - Cost tracking is isolated

Terminal Anatomy

Each terminal consists of:

Terminal Anatomy

Header Components: - Terminal Number (T1, T2, T3, T4) - Agent Name with dropdown selector - Model Name with dropdown selector - Container Icon (if running in container mode)

Output Area: - Streaming agent responses - Tool call displays - Execution results - Error messages

Status Bar (global, not per-terminal): - Current agent - Active model - Session cost - Token count

Default Behavior

  • Terminal 1 (T1) is always the main terminal and cannot be closed
  • New terminals start with redteam_agent and the default model (Alias1)
  • Each terminal maintains independent conversation history
  • Terminals can run different agents and models simultaneously

Multi-Terminal Workflows

Why Use Multiple Terminals?

Multiple terminals enable:

  1. Parallel Agent Execution: Run different agents simultaneously on the same task
  2. Perspective Comparison: Compare red team vs. blue team approaches
  3. Specialization: Assign specific roles to different agents
  4. Efficiency: Execute independent tasks in parallel
  5. Collaboration Simulation: Model team-based security workflows

Common Multi-Terminal Patterns

Pattern 1: Offensive + Defensive (2 Terminals)

Use Case: Adversarial testing with real-time defense validation

Setup: - T1: redteam_agent - Performs offensive testing - T2: blueteam_agent - Analyzes defensive posture

Workflow:

T1 > Identify attack vectors on target web application
T2 > Evaluate defensive controls for the same application

Benefits: - Immediate validation of findings - Balanced security assessment - Real-time trade-off analysis

Pattern 2: Discover + Validate + Report (3 Terminals)

Use Case: Complete vulnerability lifecycle from discovery to documentation

Setup: - T1: bug_bounter_agent - Discover vulnerabilities - T2: retester_agent - Validate findings - T3: reporting_agent - Document results

Workflow:

T1 > Hunt for authentication bypasses in target.com
T2 > <Wait for T1 findings>
T2 > Retest the authentication bypass found in T1
T3 > <After validation>
T3 > Generate report for confirmed authentication bypass

Benefits: - Clear separation of concerns - Quality assurance built-in - Professional documentation

Pattern 3: Full Security Team (4 Terminals)

Use Case: Comprehensive security assessment with maximum parallelization

Setup (Use Team #1 from sidebar): - T1: redteam_agent - Web application attacks - T2: redteam_agent - Network-level exploitation - T3: bug_bounter_agent - OWASP Top 10 focus - T4: bug_bounter_agent - API security testing

Workflow:

<Select Team #1 in sidebar>
Prompt > Perform comprehensive security assessment of target.com all

Benefits: - Maximum parallel execution - Different attack surfaces covered - Diverse perspectives - Faster overall completion

Terminal Operations

Creating Terminals

Method 1: Manual Addition

Keyboard Shortcut: Click [Add+] button in top bar

Example Workflow:

1. Start CAI TUI (1 terminal by default)
2. Click [+]
3. New terminal appears (T2)
4. Select agent from dropdown
5. Start working

Method 2: Team Selection

Steps: 1. Open sidebar (Ctrl+S) 2. Navigate to Teams tab 3. Click desired team button (e.g., "#1: 2 red + 2 bug") 4. All 4 terminals are configured automatically

Benefits of Team Selection: - Instant configuration of all terminals - Predefined agent assignments - Optimized for common workflows - One-click setup

Removing Terminals

Close Focused Terminal

Keyboard Shortcut: Ctrl+E

Behavior: - Closes currently focused terminal - Terminal 1 (T1) cannot be closed - Terminal numbers do not shift - History is lost (save session first if needed)

Focusing Terminals

Keyboard Navigation

Shortcuts: - Ctrl+N - Focus next terminal (T1 → T2 → T3 → T4 → T1) - Ctrl+B - Focus previous terminal (T1 → T4 → T3 → T2 → T1)

Mouse Click

Click anywhere in the terminal output area to focus it.

Visual Focus Indicators

Focused Terminal: - Highlighted terminal header - Brighter output area - Active input cursor

Inactive Terminals: - Dimmed header - Normal output area - Background execution continues


Team-Based Configurations

CAI TUI includes 11 preconfigured teams optimized for common security workflows.

Accessing Teams

  1. Open sidebar (Ctrl+S)
  2. Click Teams tab
  3. Browse available teams
  4. Click team button to apply

Team Composition Reference

Team Composition Best For
#1 2 redteam + 2 bug_bounter Comprehensive vulnerability discovery
#2 1 redteam + 3 bug_bounter Bug bounty with red team leadership
#3 2 redteam + 2 blueteam Adversarial offense + defense testing
#4 2 blueteam + 2 bug_bounter Defense-focused with validation
#5 red + blue + retester + bug Full security lifecycle coverage
#6 2 redteam + 2 retester Aggressive testing with validation
#7 2 blueteam + 2 retester Defensive validation and retesting
#8 4 redteam Maximum offensive power
#9 4 blueteam Comprehensive defensive analysis
#10 4 bug_bounter Intense bug bounty hunting
#11 4 retester Large-scale retesting campaigns

Team Application Behavior

When you select a team:

  1. All terminals are reconfigured with designated agents
  2. Agent dropdowns update to reflect new assignments
  3. Previous conversations are preserved in output areas
  4. Each terminal is ready to receive prompts immediately
  5. No cost impact - configuration is free

Customizing Teams

To create custom team configurations:

  1. Manually configure each terminal with desired agents
  2. Save the session: /save my_custom_team.json
  3. Load it later: /load my_custom_team.json

Parallel Execution Patterns

Pattern 1: Broadcast to All Terminals

Use Case: Execute the same task with different agent perspectives

Steps: 1. Select a team (e.g., Team #3: 2 Red + 2 Blue) 2. Type prompt in input area 3. Add "all" flag at the end of the prompt 4. Watch all terminals execute simultaneously

Example:

Prompt: Assess the security of https://target.com/api
Broadcast to: T1 (redteam), T2 (redteam), T3 (blueteam), T4 (blueteam)
Result: Four different perspectives on API security

Pattern 2: Sequential Terminal Execution

Use Case: Pass results from one terminal to another

Steps: 1. Execute in T1 2. Wait for completion 3. Reference T1 results in T2 prompt 4. Continue chain

Example:

T1 (bug_bounter) > Find all input fields on target.com
<Wait for results>
T2 (redteam) > Test the 5 input fields found by T1 for XSS vulnerabilities
<Wait for results>
T3 (retester) > Validate the XSS findings from T2
<Wait for results>
T4 (reporting) > Create report from T1, T2, and T3 findings

Pattern 3: Parallel Independent Tasks

Use Case: Execute completely different tasks simultaneously

Setup: - T1: Scan network (nmap) - T2: Enumerate web dirs (ffuf) - T3: Check DNS records - T4: Analyze SSL/TLS config

Execution:

T1 > nmap -sV -A target.com
T2 > ffuf -w wordlist.txt -u https://target.com/FUZZ
T3 > Enumerate all DNS records for target.com
T4 > Analyze SSL/TLS configuration of target.com

Benefits: - Maximizes parallelization - Reduces total execution time - Efficient resource utilization

Pattern 4: Focused Execution with Monitoring

Use Case: One agent works while others monitor specific aspects

Setup: - T1: redteam_agent (main executor) - T2: blueteam_agent (monitors defensive gaps) - T3: dfir_agent (monitors artifacts/logs) - T4: reporting_agent (live documentation)

Workflow:

T1 > Perform full penetration test on target.com
<While T1 works:>
T2 > Monitor defensive weaknesses as T1 progresses
T3 > Track and analyze artifacts generated by T1
T4 > Document findings in real-time from T1, T2, T3

Terminal State Management

Terminal States

Each terminal can be in one of four states:

1. Active State

  • Visual: Normal border, bright colors
  • Behavior: Ready to receive input
  • Actions: Can send prompts, change agent/model

2. Focused State

  • Visual: Highlighted border (accent color)
  • Behavior: Receives keyboard input
  • Actions: All actions available, input directed here

3. Busy State

  • Visual: Spinner/progress indicator
  • Behavior: Agent is executing
  • Actions: Can cancel (Ctrl+C), cannot send new prompts

4. Error State

  • Visual: Red border or error indicator
  • Behavior: Execution failed
  • Actions: Can retry, clear error, or continue

State Transitions

Active ──[Send Prompt]──> Busy ──[Complete]──> Active
   └──[Error]──> Error ──[Clear]──> Active

Active ──[Focus Terminal]──> Focused ──[Focus Other]──> Active

Managing Terminal State

Canceling Execution

Method 1: Ctrl+C (focused terminal only)

Method 2: Escape twice (all terminals)

Method 3: /kill command

Clearing Errors

Command: /clear (clears visual errors, preserves history)

Alternative: Click error message dismiss button (if shown)

Resetting Terminal

Steps: 1. /flush - Clear conversation history 2. /clear - Clear visual output 3. Select new agent (if desired) 4. Start fresh


Advanced Techniques

Terminal-Specific Commands

Target commands to specific terminals without focusing them.

Syntax: T<num>:<command>

Examples:

# Change agent in T2 without leaving T1
T2:/agent blueteam_agent

# Clear T3 output
T3:/clear

# Check T4 cost
T4:/cost

# Execute prompt in T2
T2:Scan target.com for open ports

Benefits: - No context switching required - Efficient multi-terminal management - Script-friendly

Dynamic Terminal Allocation

Adjust terminal count based on task complexity.

Simple Task (1-2 terminals): - Single perspective sufficient - Limited scope - Quick execution

Medium Task (2-3 terminals): - Multiple perspectives valuable - Moderate complexity - Benefit from specialization

Complex Task (4 terminals): - Full team required - High complexity - Maximum parallelization needed

Terminal Output Management

Copy Terminal Output

Method 1: Mouse selection + Ctrl+C

Method 2: Export session + extract terminal data

Method 3: /save and process saved file

Terminal Output Filtering

Technique: Use agent's built-in filtering

Prompt: Summarize key findings from previous responses

Clear Old Output

Command: /clear (visual only)

Alternative: /flush (history too)


Best Practices

1. Start Small, Scale Up

Begin with 1-2 terminals. Add more only when parallelization provides clear benefit.

2. Use Preconfigured Teams

Leverage the 11 built-in teams instead of manual configuration.

3. Name Your Sessions

Save sessions with descriptive names:

/save 2025-10-27_webapp_pentest_team3.json

4. Monitor Costs Per Terminal

Check costs regularly:

/cost    # Current terminal
/cost all  # All terminals

5. Clear Between Tasks

Reset terminals between unrelated tasks:

/flush all
/clear

6. Document Terminal Roles

Add a comment in the first prompt of each terminal:

T1 > [RECON] Enumerate target.com infrastructure
T2 > [EXPLOIT] Test for authentication bypass
T3 > [VALIDATE] Confirm findings from T2
T4 > [REPORT] Document all findings

7. Use Broadcast Wisely

Broadcast is powerful but expensive. Use it when you truly need multiple perspectives on the same task.

8. Leverage Terminal Independence

Each terminal is independent - use this for: - Different phases of testing - Completely separate tasks - Long-running operations in background terminals


Troubleshooting

Terminal Not Responding

Symptoms: Terminal stuck in busy state, no output

Solutions: 1. Wait (some operations take time) 2. Cancel with Ctrl+C 3. Check /mcp status if using MCP tools 4. Restart terminal: /flush, /clear, then retry

Terminals Not Syncing with Team Selection

Symptoms: Agent dropdowns don't update after selecting team

Solutions: 1. Check that sidebar is visible (Ctrl+S) 2. Click team button again 3. Manually update agent dropdowns if issue persists 4. Report bug with cai --version output

Layout Not Adjusting

Symptoms: Terminal layout doesn't change when adding terminals

Solutions: 1. Resize terminal window (trigger layout recalc) 2. Toggle fullscreen mode (Ctrl+T) and back 3. Restart TUI if issue persists

Cost Tracking Incorrect

Symptoms: Cost numbers seem wrong or don't update

Solutions: 1. Check /cost all for complete breakdown 2. Verify model pricing with /env 3. Check if multiple terminals using expensive models 4. Save session and review cost data offline
