+
+# Or switch agents during a session
+CAI>/agent redteam_agent
+
+# List all available agents with descriptions
+CAI>/agent list
+
+# Get detailed info about a specific agent
+CAI>/agent info redteam_agent
+```
+
+### Choosing the Right Agent
+
+- **For general pentesting**: Start with `redteam_agent`
+- **For web applications**: Use `bug_bounter_agent`
+- **For forensics**: Use `dfir_agent` or `memory_analysis_agent`
+- **For IoT/embedded**: Try `subghz_sdr_agent` or `reverse_engineering_agent`
+- **For network security**: Use `network_traffic_analyzer` or `blueteam_agent`
+- **For mobile apps**: Use `android_sast_agent`
+- **For wireless networks**: Use `wifi_security_tester`

+## Common Agent Workflows
+
+### Scenario 1: Full Web Application Pentest
+
+```bash
+# 1. Start with reconnaissance
+CAI>/agent bug_bounter_agent
+CAI> Scan https://target.com for vulnerabilities
+
+# 2. Switch to exploitation
+CAI>/agent redteam_agent  
+CAI> Exploit the SQL injection found at /login
+
+# 3. Post-exploitation analysis
+CAI>/agent dfir_agent
+CAI> Analyze the logs to understand the attack surface
+```
+
+### Scenario 2: IoT Device Security Assessment
+
+```bash
+# 1. RF signal analysis
+CAI>/agent subghz_sdr_agent
+CAI> Analyze the 433MHz signals from the device
+
+# 2. Firmware analysis
+CAI>/agent reverse_engineering_agent
+CAI> Extract and analyze the firmware from dump.bin
+
+# 3. Memory analysis if device captured
+CAI>/agent memory_analysis_agent
+CAI> Analyze the memory dump for secrets
+```
+
+### Scenario 3: Network Incident Response
+
+```bash
+# 1. Network traffic analysis
+CAI>/agent network_traffic_analyzer
+CAI> Analyze capture.pcap for suspicious activity
+
+# 2. Forensic investigation
+CAI>/agent dfir_agent
+CAI> Investigate the compromised host logs
+
+# 3. Defensive recommendations
+CAI>/agent blueteam_agent
+CAI> Provide mitigation strategies based on findings
+```

+## Basic Configuration
 
 Key agent properties include:
 
--   `name`: of the agent e.g. the name of `one_tool_agent` is 'CTF Agent'.
--   `instructions`: known as the system prompt.
--   `model`: which LLM to use, and optional `model_settings` to configure their parameters like temperature, top_p, etc.
--   `tools`: Tools that the agent can use to achieve its tasks.
--   `handoffs`: wich allows an agent to delegate tasks to another agent.

-- For understanding what it returns, see [results documentation](results.md). 
+### Performance Optimization

+
+## Agent Best Practices
+
+### 1. Start with the Right Agent
+
+Don't use a specialized agent for general tasks. Match the agent to your objective:
+
+```bash
+# ✅ Good: Using bug bounty agent for web testing
+CAI_AGENT_TYPE=bug_bounter_agent cai
+CAI> Test https://target.com for vulnerabilities
+
+# ❌ Bad: Using reverse engineering agent for web testing
+CAI_AGENT_TYPE=reverse_engineering_agent cai
+CAI> Test https://target.com for vulnerabilities
+```
+
+### 2. Switch Agents as Needed
+
+Don't hesitate to switch agents mid-session:
+
+```bash
+CAI>/agent bug_bounter_agent
+CAI> Find vulnerabilities in the web app
+# ... agent finds SQL injection ...
+
+CAI>/agent redteam_agent
+CAI> Exploit the SQL injection to gain access
+# ... successful exploitation ...
+
+CAI>/agent dfir_agent
+CAI> Analyze what data was exposed during the test
+```
+
+### 3. Monitor Resource Usage
+
+Keep an eye on costs and performance:
+
+```bash
+# During session, check costs
+CAI>/cost
+
+# Set limits before starting
+CAI_PRICE_LIMIT="5.00" CAI_MAX_TURNS=50 cai
+```
+
+### 4. Save Successful Sessions
+
+Use `/load` to reuse successful approaches:
+
+```bash
+
+# In future session
+CAI>/load logs/logname.jsonl
+```
