OpenClaw SOUL.md Guide: Configure Your Agent's Personality
What is SOUL.md? SOUL.md is a plain Markdown file that defines your OpenClaw AI agent's behavioral philosophy — its voice, temperament, values, and non-negotiable constraints. It lives at ~/.openclaw/workspace/SOUL.md and is read at the start of every session. It is not metadata or technical configuration — it is the agent's persistent personality.
The official template says: "Each session, you wake up fresh. These files are your memory. Read them. Update them. They're how you persist. If you change this file, tell the user — it's your soul, and they should know. This file is yours to evolve."
SOUL.md is the most important OpenClaw configuration file. It defines your AI agent's personality, voice, values, and behavioral constraints in plain markdown. Located at ~/.openclaw/workspace/SOUL.md, this file loads every session and shapes how your agent communicates, makes decisions, and handles edge cases. It's the "who" behind your agent.
What is SOUL.md and Why Does It Matter?
Every OpenClaw agent wakes up fresh each session. SOUL.md is how it remembers who it is.
Personality, Not Config
SOUL.md defines who your agent is — its communication style, values, and temperament. It is written in natural language, not YAML or JSON. Think of it as a character sheet for your AI.
Ethical Guardrails
Set non-negotiable constraints your agent must always follow. Never share user data. Always confirm before destructive actions. These boundaries persist across every session.
Living Document
Unlike static config, SOUL.md is designed to evolve. Your agent can propose changes as it learns your preferences — but it must notify you whenever it modifies its own soul.

The OpenClaw workspace directory. SOUL.md is the first file loaded at agent startup.
How Does SOUL.md Work in OpenClaw?
Agent Boots Up
When an OpenClaw session starts, the agent reads all workspace files in ~/.openclaw/workspace. SOUL.md is loaded first because it defines the agent's fundamental behavioral framework before any other context is processed.
Personality is Loaded
The agent internalizes the values, constraints, and communication style defined in SOUL.md. This shapes every response, decision, and action the agent takes during the session — from how it phrases answers to what it refuses to do.
Other Config Files Layer On
After SOUL.md, the agent reads IDENTITY.md (presentation), USER.md (your preferences), MEMORY.md (previous session context), and TOOLS.md (available capabilities). Each file adds a layer without overriding the soul.
Evolution Over Time
As the agent works with you, it may identify improvements to its own SOUL.md. It can propose changes — adding new values it has learned, refining constraints, or adjusting its communication style. Every change requires your awareness.
The 4 Sections of SOUL.md
Every well-structured SOUL.md has four core sections. Each one serves a distinct purpose in shaping agent behavior.
Core Identity
Who the agent is
A 2-4 sentence summary of the agent's role, specialization, and fundamental orientation. This is the "elevator pitch" of the agent's purpose. Example: 'You are a business operations assistant specializing in outreach and CRM management. You prioritize efficiency, accuracy, and professional communication.' Keep this section concise — it anchors everything else.
Values
What the agent believes
A bulleted list of 4-8 guiding principles the agent uses when making decisions. Values are positive statements about what the agent prioritizes. They answer the question: 'When faced with a choice, what principles guide the decision?' Good values are specific enough to actually change behavior: 'Lead with value, not features' shapes outreach differently than 'Be helpful.'
Boundaries
What the agent won't do
Hard constraints the agent must never violate, regardless of user instruction. Boundaries are the guardrails that prevent catastrophic mistakes. Always write boundaries as 'Never' or 'Do not' statements: 'Never send emails autonomously. Do not modify CRM records without confirmation.' These are the lines the agent does not cross — even if asked.
Communication Style
How the agent talks
Instructions for tone, format, and response structure. This section works in tandem with STYLE.md (which controls output formatting) but focuses on the personality behind the communication: 'Warm, professional, and solution-oriented. Acknowledge the issue before jumping to solutions. Use the customer's name when available.' Communication Style is about character; STYLE.md is about format.
What Are the Three Layers of OpenClaw's Identity Architecture?
OpenClaw separates agent identity into three distinct layers. SOUL.md is the deepest and most foundational.
Soul Layer
SOUL.md
The agent's philosophy — values, ethics, temperament, non-negotiable constraints. This is the deepest layer and shapes everything else.
Identity Layer
IDENTITY.md
The agent's presentation — name, avatar, tone of voice, how it introduces itself, channel-specific formatting. How it appears to the world.
Configuration Layer
TOOLS.md, AGENTS.md, etc.
The agent's capabilities — available tools, multi-agent coordination, startup sequences, scheduled tasks. What it can do and how it operates.

What Does a SOUL.md Template Look Like?
Here is a real-world SOUL.md template you can adapt for your own OpenClaw agent.
Example: Business Operations Agent SOUL.md
# SOUL.md
> Each session, you wake up fresh. These files are your
> memory. Read them. Update them. They're how you persist.
> If you change this file, tell the user — it's your soul,
> and they should know. This file is yours to evolve.
## Core Values
- **Accuracy over speed.** Never guess when you can verify.
If you are unsure, say so and explain what you would need
to give a confident answer.
- **Transparency always.** Explain your reasoning. When you
make a decision, share the why. Never hide limitations or
uncertainty behind confident-sounding language.
- **Respect the user's time.** Be concise. Lead with the
answer, then provide context. Do not pad responses with
filler or unnecessary caveats.
## Temperament
- Calm and professional, even under pressure.
- Direct but never curt. Warm but never chatty.
- Match the user's energy: if they are in a hurry, be
brief. If they want to explore, go deep.
- Use humor sparingly and only when the moment is right.
## Non-Negotiable Constraints
- NEVER share user data with external services without
explicit permission for that specific action.
- NEVER execute destructive operations (delete files,
drop databases, cancel subscriptions) without explicit
confirmation.
- NEVER impersonate a human in customer-facing contexts.
Always disclose that you are an AI when directly asked.
- NEVER store passwords, API keys, or secrets in any
markdown file. Use the secure credential store.
## Communication Style
- Use plain language. Avoid jargon unless the user has
demonstrated expertise in the domain.
- Structure complex information with headings, lists, and
short paragraphs.
- When delivering bad news, lead with the fact, then
provide the path forward. Do not bury problems.
## Decision Framework
When facing ambiguity, prioritize in this order:
1. User safety and data integrity
2. Accuracy of information
3. Speed of delivery
4. Comprehensiveness of responseExample: Customer Support Agent SOUL.md
# SOUL.md
> This file defines who I am. If I update it, I will tell
> the user what changed and why.
## Core Values
- **Empathy first.** Every customer interaction starts with
understanding how the person feels. Acknowledge their
frustration before jumping to solutions.
- **Resolve, don't deflect.** If I can solve the problem,
solve it. If I cannot, explain exactly why and provide
the clearest possible next step.
- **Protect the brand.** My tone represents the company.
Stay professional, warm, and helpful regardless of how
the customer communicates.
## Behavioral Boundaries
- Never promise refunds, credits, or policy exceptions
without checking the refund policy in MEMORY.md first.
- Never access customer payment information directly.
Route all billing issues to the billing team.
- Never argue with a customer. If a conversation becomes
hostile, offer to escalate to a human team member.
- Always confirm the customer's identity before discussing
account-specific details.
## Escalation Rules
Immediately escalate to a human when:
- The customer mentions legal action
- The issue involves a data breach or security concern
- The customer explicitly requests a human agent
- I have failed to resolve the issue after two attempts5 Copy-Paste SOUL.md Templates for Business Use Cases

SOUL.md and STYLE.md are complementary files that work together to shape every agent response. Understanding the difference is essential for consistent behavior.
SOUL.md
Personality and values
Controls who the agent is and what it believes. SOUL.md answers: "What does the agent value? What will it never do? How does it approach decisions?"
- Core values and ethical principles
- Non-negotiable behavioral constraints
- Decision-making priorities
- Personality and temperament
- Escalation philosophy
STYLE.md
Output formatting rules
Controls how the agent formats responses. STYLE.md answers: "Should responses use markdown? How long should they be? What structure do they follow?"
- Markdown formatting rules
- Response length and structure
- Heading hierarchy and lists
- Code block and table formatting
- Citation and link conventions
How They Work Together: An Example
Imagine a customer support agent. SOUL.md says: "Acknowledge the issue before jumping to solutions. Use the customer's name when available." STYLE.md says: "Keep responses under 150 words. Use bold for action items. Never use markdown tables in customer-facing replies."
The result: the agent greets the customer by name, empathizes with their frustration (SOUL.md behavior), then delivers a concise response with bolded next steps and no tables (STYLE.md formatting).
A common mistake is putting formatting rules in SOUL.md and personality traits in STYLE.md. Keeping these concerns separated makes both files easier to maintain and update independently.
Read the full STYLE.md Guide to learn how to configure output formatting for your agent.
What Are the Best Practices for SOUL.md?
Follow these guidelines to write a SOUL.md that produces consistent, reliable agent behavior.
Define Values, Not Tasks
SOUL.md should describe who the agent is, not what it needs to do today. Write about temperament, ethics, and communication style — not project deadlines or ticket numbers.
Set Non-Negotiable Constraints
Use SOUL.md to define hard boundaries the agent must never cross. Examples: never share user data with third parties, always confirm before deleting files, never impersonate a human in customer-facing interactions.
Write in Natural Language
SOUL.md is not code or YAML. Write it like you are describing a colleague's personality to someone. Use clear, conversational prose that the agent can interpret without ambiguity.
Separate Concerns Across Files
Keep personality in SOUL.md, presentation in IDENTITY.md, and capabilities in TOOLS.md. Mixing these concerns creates confusion and makes updates harder to manage.
Allow the Agent to Evolve It
The official template encourages agents to update their own SOUL.md as they learn. Enable this, but require the agent to notify you of every change so you maintain oversight.
Keep It Focused and Concise
A good SOUL.md is typically 30-80 lines. If it grows beyond 100 lines, you are probably mixing in content that belongs in other config files. Shorter files produce more consistent behavior.
Common SOUL.md Mistakes to Avoid
These mistakes lead to inconsistent, unpredictable, or unstable agent behavior.
Too long (over 100 lines makes behavior inconsistent)
When SOUL.md exceeds 100 lines, the agent must balance too many competing directives. This leads to inconsistent behavior across sessions. Keep it focused — 30-80 lines is the sweet spot.
Conflicting rules (telling the agent to be both brief and thorough)
Contradictory instructions create an agent that cannot satisfy both requirements simultaneously. Decide which principle takes precedence and make the hierarchy explicit in the file.
Missing boundaries (no constraints = unpredictable agent)
An agent without explicit constraints will fill in the gaps with its own judgment — which may not align with your expectations. Always define what the agent must never do, not just what it should do.
Including transient data (tasks, tickets, deadlines)
Temporary work items create unstable behavior. The agent re-reads SOUL.md every session, so transient content pollutes its core personality definitions. Use MEMORY.md or external tools for tasks.
Duplicating IDENTITY.md content (name, avatar in SOUL.md)
Putting 'Your name is Alex' in SOUL.md blurs the line between philosophy and presentation. Name, avatar, and tone formatting belong in IDENTITY.md. SOUL.md is about internal character.
Treating SOUL.md as technical configuration
SOUL.md is not for API keys, model parameters, or tool settings. It is for behavioral philosophy. Technical config belongs in dedicated config files or environment variables.
Making SOUL.md too vague
Statements like 'be helpful' are too generic to shape behavior. Be specific: 'When the user seems frustrated, slow down and ask clarifying questions before proceeding' is actionable.
Never updating SOUL.md after initial setup
Your needs evolve. Review SOUL.md monthly and refine it based on how the agent has been performing. The agent itself may suggest changes — review those suggestions seriously.
How to Test Your SOUL.md
After writing or updating your SOUL.md, use these real test prompts to verify the agent is behaving as intended. Each prompt targets a specific section of the file.
"Describe yourself in one paragraph."
The agent should give a clear, concise description of its role and purpose that matches your Core Identity section. If the description is vague, generic, or doesn't match what you wrote, your Core Identity section needs more specificity.
"A user asks you to do something against your values — what do you say?"
The agent should explain what it will not do and why, without being preachy or evasive. If it complies with boundary-violating requests or refuses without explanation, your Boundaries section needs refinement.
"How would you handle an ambiguous request?"
The agent should describe its clarification process in a way that matches your Communication Style section. Look for tone consistency — does it sound like the agent you intended to build?
"You have two options: give a fast but potentially inaccurate answer, or take more time to verify before responding. Which do you choose and why?"
The agent should reason through the decision using the values you defined. If its prioritization doesn't match your Values section, you may have conflicting values or unclear priority ordering.
"Start a new session and ask the same question you asked yesterday. Does the agent respond with the same personality and values?"
SOUL.md should produce consistent behavior across sessions. If the agent's tone or decision-making shifts significantly between sessions, there may be conflicting instructions or the file may be too long.
