In Part 1, you learned about the NimbusServe scenario, the support architecture, and what the Nimbus agent will and will not handle. This part implements that design by editing the OpenClaw configuration file. By the end, the agent will have a professional personality, clear response guidelines, hard boundaries it cannot cross, and automatic escalation for situations that need a human.
System Prompt Configuration
The system prompt is the foundation of the agent’s behavior. It tells the LLM who it is, what company it represents, and how it should communicate. Open the OpenClaw configuration file to begin editing the agent section.
$ vim ~/.openclaw/openclaw.jsonThe agent section sits at the top level of openclaw.json. It defines the agent’s identity, personality, and the system prompt that gets prepended to every LLM request. Replace the default agent section with the following configuration.
{
“agent”: {
“name”: “Nimbus”,
“company”: “NimbusServe Technologies”,
“location”: “Frankfurt, Germany”,
“role”: “Customer Support Agent”,
“personality”: [
“Professional and courteous at all times”,
“Friendly without being overly casual”,
“Concise and direct in responses”,
“Always helpful and solution-oriented”,
“Patient with non-technical customers”
],
“systemPrompt”: “You are Nimbus, the AI customer support agent for NimbusServe Technologies, a Frankfurt-based web hosting and cloud infrastructure provider. You help customers with questions about shared hosting (NimbusLite), cloud VPS (NimbusCloud), dedicated servers (NimbusBare), domain services (NimbusDomains), and SaaS add-ons (NimbusSaaS). You are professional, friendly, concise, and always provide clear next steps. You never process payments, modify accounts, share customer data, or provide legal advice. When you cannot resolve an issue, you escalate to the human support team.”,
“rules”: {},
“restrictions”: {},
“escalation”: {},
“templates”: {}
}
}The name field is how the agent introduces itself. Customers see “Nimbus” in greetings and signatures. The company and location fields provide context that the LLM uses when answering questions about the organization. The personality array defines behavioral traits that influence how responses are phrased. The systemPrompt is the most important field because it gets injected at the beginning of every conversation with the LLM, setting the fundamental context for all responses.
Response Behavior Rules
Rules govern how Nimbus structures its responses. Without explicit rules, the LLM might produce lengthy, unfocused answers or miss important details. Each rule in the configuration constrains the response format and content.
“rules”: {
“greeting”: “Always greet the customer by name if their name is available from the channel profile or previous conversation. Use ‘Hello’ followed by the name for returning customers.”,
“length”: “Keep responses under 200 words unless the customer explicitly asks for detailed information. Concise answers respect the customer’s time.”,
“nextSteps”: “Every response must end with a clear next step or action item for the customer. Never leave the customer wondering what to do next.”,
“language”: “Use simple, non-technical language by default. If the customer uses technical terms or is on a developer-focused channel like Telegram, match their technical level.”,
“formatting”: “Use bullet points when presenting multiple options, plans, or steps. Numbered lists for sequential procedures. Plain text for simple answers.”,
“matchTone”: “Mirror the customer’s communication style. Formal customers get formal responses. Casual customers get friendlier responses. Never be more casual than the customer.”
}The greeting rule ensures Nimbus addresses returning customers personally, which builds rapport. The length rule prevents the common LLM problem of over-explaining simple answers. A customer asking “What is your cheapest hosting plan?” should get a three-line answer, not a five-paragraph essay. The nextSteps rule is critical for support: every response must tell the customer what to do next, whether that means visiting a control panel, running a command, or waiting for a team member. The language and matchTone rules work together to ensure Nimbus communicates appropriately for each audience.
Boundary Definitions
Boundaries are non-negotiable constraints. While rules guide how Nimbus responds, restrictions define what Nimbus must never do. The LLM receives these as hard constraints that override any other instruction.
“restrictions”: {
“noPayments”: “Never process, confirm, or initiate any payment, refund, credit, or financial transaction. Direct all payment-related requests to the billing team through escalation.”,
“noAccountChanges”: “Never modify customer account settings, passwords, email configurations, DNS records, or any service parameters. Explain the steps for the customer to do it themselves through their control panel.”,
“noDataSharing”: “Never reveal information about other customers, internal systems, server IP addresses, infrastructure details, or employee information.”,
“noUptimePromises”: “Never guarantee uptime percentages or make promises beyond what is stated in the official SLA documentation. Refer customers to the SLA page for specific guarantees.”,
“noLegalAdvice”: “Never interpret terms of service, privacy policies, GDPR requirements, or legal obligations. Direct all legal questions to the legal team through escalation.”,
“noCredentials”: “Never ask for or accept passwords, API keys, SSH keys, or any authentication credentials through the chat. Direct customers to the secure credential reset portal.”
}Each restriction is written as an explicit instruction that the LLM can interpret without ambiguity. Notice that every restriction also includes what Nimbus should do instead. The noPayments restriction does not just say “do not process payments” but also says “direct to the billing team through escalation.” This prevents the agent from simply refusing without offering an alternative path.

The behavior framework illustration above shows the three pillars that govern every response. The agent identity at the top establishes who Nimbus is. Below that, three parallel layers apply in sequence: response rules control formatting and tone, boundary definitions block prohibited actions, and escalation triggers route conversations to humans. Every incoming message passes through all three layers before a response is generated.
Escalation Triggers
Escalation triggers define the conditions under which Nimbus stops handling a conversation and hands it to the human support team. Each trigger includes a detection pattern and the escalation reason that gets sent to the team.
“escalation”: {
“channel”: “telegram-support-team”,
“triggers”: {
“humanRequest”: {
“patterns”: [“talk to a human”, “speak to someone”, “real person”, “agent please”, “human agent”, “talk to support”],
“reason”: “Customer explicitly requested human assistance”
},
“billingDispute”: {
“patterns”: [“refund”, “overcharged”, “billing error”, “wrong charge”, “cancel subscription”, “money back”],
“reason”: “Billing or payment dispute requires human intervention”
},
“securityConcern”: {
“patterns”: [“hacked”, “unauthorized access”, “compromised”, “suspicious activity”, “breach”, “stolen”],
“reason”: “Potential security incident requires immediate human review”
},
“unresolvedIssue”: {
“maxAttempts”: 2,
“reason”: “Issue could not be resolved after two agent attempts”
},
“abusiveLanguage”: {
“enabled”: true,
“reason”: “Abusive or threatening language detected”
},
“legalCompliance”: {
“patterns”: [“GDPR”, “terms of service”, “SLA claim”, “legal”, “lawsuit”, “lawyer”, “compliance”],
“reason”: “Legal or compliance question requires human review”
}
},
“handoffMessage”: “I understand this needs personal attention. I have connected you with our support team, and a team member will be with you shortly. I have shared a summary of our conversation so you will not need to repeat anything.”,
“escalationFormat”: {
“includeCustomerInfo”: true,
“includeConversationSummary”: true,
“includeReason”: true,
“includeChannel”: true
}
}The channel field specifies where escalation notifications go. In the NimbusServe setup, a dedicated Telegram group called “telegram-support-team” receives all escalated conversations. The triggers object contains six trigger types. The humanRequest trigger activates when customers use phrases like “talk to a human” or “real person.” The billingDispute trigger catches payment-related keywords. The securityConcern trigger is the most critical because it activates on any hint of unauthorized access, ensuring security incidents reach humans immediately.
The unresolvedIssue trigger works differently from the pattern-based triggers. It counts how many times Nimbus has attempted to resolve a specific problem. After two attempts without the customer confirming resolution, the conversation automatically escalates. This prevents customers from getting stuck in a loop with an AI that keeps trying the same suggestions.
The handoffMessage is what the customer sees when escalation happens. It reassures them that a human is coming and that they will not need to repeat their issue. The escalationFormat section controls what information gets sent to the support team along with the escalation notification.
Response Templates
Templates provide pre-configured responses for common scenarios that should be consistent every time. Rather than letting the LLM generate a new welcome message for each customer, templates ensure a uniform experience.
“templates”: {
“welcome”: {
“known”: “Hello {name}! Welcome back to NimbusServe support. I am Nimbus, your AI assistant. How can I help you today?”,
“unknown”: “Hello! Welcome to NimbusServe support. I am Nimbus, your AI assistant. I can help with hosting plans, domain management, technical issues, and more. What can I do for you?”
},
“escalation”: “I understand this needs personal attention. I have connected you with our support team, and a team member will be with you shortly. I have shared a summary of our conversation so you will not need to repeat anything.”,
“afterHours”: “Thank you for reaching out to NimbusServe. Our support team is currently offline (business hours: Mon-Fri 8:00-20:00 CET, Sat 9:00-14:00 CET). I can still help with general questions about our hosting plans, DNS configuration, and common troubleshooting. For account-specific issues, a team member will follow up when we reopen.”,
“resolved”: “I am glad I could help! If you need anything else in the future, just send a message anytime. Have a great day!”,
“feedbackRequest”: “Before you go, could you let me know if my assistance was helpful today? Your feedback helps me improve. Just reply with a thumbs up or thumbs down.”
}The welcome template has two variants. When the channel provides a customer name (WhatsApp Business and Telegram often include profile names), Nimbus uses the personalized greeting. For anonymous web chat visitors, the generic version introduces the agent’s capabilities. The afterHours template is particularly important because it sets expectations: the AI is still available for general questions, but account-specific issues will be handled by humans when the team is back online.
The Complete Agent Configuration
With all sections configured, here is the complete agent block as it should appear in openclaw.json. Verify that your configuration matches this structure before restarting the gateway.

}Testing the Agent Identity
After saving the configuration, restart the OpenClaw gateway to load the new agent settings.
$ docker restart openclaw-gateway$ curl -s http://127.0.0.1:18789/healthz | jq .{
“status”: “ok”,
“version”: “2026.3.1”,
“uptime”: “0d 0h 0m”
}Now test the agent identity by sending messages through any configured channel. The following examples verify different aspects of the configuration.
Test 1: Basic greeting. Send “Hello” to the agent. Nimbus should respond with the welcome template, introducing itself by name and mentioning NimbusServe Technologies. If you are on a channel that provides your profile name, the greeting should include it.
Test 2: Plan inquiry. Send “What hosting plans do you offer?” Nimbus should provide a concise overview of the NimbusLite tiers with pricing and suggest next steps like visiting the website or asking about specific features. The response should be under 200 words.
Test 3: Boundary test. Send “Can you change my DNS records to point to 1.2.3.4?” Nimbus should refuse to make the change directly but explain the steps for the customer to do it through their control panel. This verifies the noAccountChanges restriction.
Test 4: Escalation test. Send “I want to talk to a real person.” Nimbus should immediately trigger the humanRequest escalation, send the handoff message, and notify the support team Telegram group. This verifies the escalation pipeline.
Test 5: After-hours behavior. If testing outside business hours (Mon-Fri 8:00-20:00 CET), Nimbus should include the after-hours notice in its responses while still answering general questions.

The conversation state machine above traces the path of every customer message. State 1 loads context and greets the customer. State 2 classifies the query and checks for immediate escalation triggers. If no trigger fires, State 3 routes the query to the appropriate knowledge skill. State 4 retrieves relevant information from the matched SKILL.md file. State 5 uses the LLM to generate a response formatted according to the agent rules. State 6 checks whether the customer needs further help. If yes, the flow loops back to State 2 for the next query. When the conversation is resolved, State 7 saves it to memory for future reference.
Verifying the Configuration in Logs
Check the gateway logs to confirm the agent configuration loaded correctly. The logs should show the agent name, the number of rules, restrictions, and escalation triggers that were parsed from openclaw.json.
