Agent Builder Plus

Agent Builder Plus (OpenClaw)

Design and generate a complete OpenClaw agent workspace with strong defaults and advanced-user-oriented clarifying questions.

Quick Start

# 1. Read skill documentation
Read SKILL.md and references/openclaw-workspace.md

# 2. Answer interview questions
Provide answers for: job statement, surfaces, autonomy level, prohibitions, memory, tone, tool posture

# 3. Generate workspace files
The skill will create: IDENTITY.md, SOUL.md, AGENTS.md, USER.md, HEARTBEAT.md

# 4. Verify and test
Run acceptance tests to validate behavior

Canonical references

• Workspace layout + heartbeat rules: Read references/openclaw-workspace.md
• File templates/snippets: Read references/templates.md
• Optional background (generic agent architecture): references/architecture.md

Workflow: build an agent from scratch

Phase 1 - Interview (ask clarifying questions)

Ask only what you need; keep it tight. Prefer multiple short rounds over one giant questionnaire.

Minimum question set (advanced):

1. Job statement: What is the agent's primary mission in one sentence?
2. Surfaces: Which channels (Telegram/WhatsApp/Discord/iMessage/Feishu)? DM only vs groups?
3. Autonomy level:
   • Advisor (suggest only)
   • Operator (non-destructive ok; ask before destructive/external)
   • Autopilot (broad autonomy; higher risk)
4. Hard prohibitions: Any actions the agent must never take?
5. Memory: Should it keep curated MEMORY.md? What categories matter?
6. Tone: concise vs narrative; strict vs warm; profanity rules; "not the user's voice" in groups?
7. Tool posture: tool-first vs answer-first; verification requirements.

Error recovery:

• If user provides incomplete answers: Ask follow-up questions for missing information
• If user is unsure about autonomy level: Explain trade-offs and suggest starting with "Operator"
• If user wants to skip questions: Explain why each question matters for agent behavior

Phase 2 - Generate workspace files

Generate these files (minimum viable OpenClaw agent):

• IDENTITY.md
• SOUL.md
• AGENTS.md
• USER.md
• HEARTBEAT.md (often empty by default)
• BOOTSTRAP.md (for first-run guidance)

Optionals:

• MEMORY.md (private sessions only)
• memory/YYYY-MM-DD.md seed (today) with a short "agent created" entry
• TOOLS.md starter (if the user wants per-environment notes)

File creation commands:

# Create workspace directory
mkdir -p /path/to/workspace/memory

# Create files (use write tool with correct parameters)
# Important: Use `file_path` parameter, not `path`
# Example:
# write:
#   file_path: /path/to/workspace/IDENTITY.md
#   content: "content here"

# For large files (>2000 bytes), consider using file-writer skill
# or split content into smaller chunks

Note: If you encounter "Missing required parameter: path (path or file_path)" error, ensure you're using file_path parameter in your write tool calls.

Error handling:

• If directory creation fails: Check permissions and path validity
• If file write fails: Verify disk space and write permissions
• If template reference fails: Ensure references/templates.md exists

Error recovery:

• If directory creation fails: Check parent directory permissions, try alternative path
• If file write fails: Check disk space, verify write permissions, retry with reduced content
• If template reference fails: Verify references/ directory exists, check file permissions

Use templates from references/templates.md but tailor content to the answers.

Phase 2.5 - Register agent with OpenClaw

⚠️ CRITICAL WARNING: Channel Conflict Prevention

NEVER bind a new agent to the same channel as the main agent!

This will cause the new agent to hijack the main agent's channel, making it impossible to communicate with the main agent.

Before registering, check existing agent bindings:

# List all agents and their bindings
openclaw agents list

# Check which channels are already in use
openclaw channels list

Channel binding rules:

1. Main agent (大鱼): Always uses the primary Feishu DM channel
2. New agents: Must use DIFFERENT channels or sub-channels
3. Testing: Use /agentname command binding for testing
4. Production: Create separate Feishu apps or use different channels

Backup configuration first:

# Backup openclaw.json before modification
cp ~/.openclaw/openclaw.json ~/.openclaw/openclaw.json.backup

Register the agent:

# Add agent to OpenClaw configuration
openclaw agents add <agent-name> --workspace /path/to/workspace

# Example 1: Use independent workspace (recommended - each agent has its own workspace)
openclaw agents add my-assistant --workspace ~/.openclaw/workspace-my-assistant

# Example 2: Use default workspace (for single agent setup only)
openclaw agents add my-assistant --workspace ~/.openclaw/workspace

Channel binding options:

Feishu:

• Direct binding: Configure in Feishu app settings (recommended for production)
  • ⚠️ WARNING: Do NOT bind to the same Feishu app as main agent
  • Create a separate Feishu app for the new agent
• Command binding: Use /agentname in Feishu messages (for testing)
  • This is SAFE - does not hijack channels
• Multiple channels: The agent can be bound to multiple channels simultaneously

Telegram:

• Create a separate bot token for each agent
• Do NOT share bot tokens between agents
• Use different bot usernames

WhatsApp:

• Use different phone numbers for each agent
• Do NOT share WhatsApp Business API credentials

Discord:

• Use different bot tokens for each agent
• Create separate Discord applications
• Do NOT share bot tokens

iMessage:

• Each agent should use a different Apple ID
• Do NOT share iMessage credentials

Authentication configuration (if needed):

# Edit auth-profiles.json for external service access
# Location: ~/.openclaw/auth-profiles.json

# Example structure:
{
  "feishu": {
    "appId": "cli_xxxxx",
    "appSecret": "xxxxx"
  },
  "telegram": {
    "botToken": "your-bot-token"
  }
}

Model provider configuration (optional):

If the new agent needs to use custom model providers, you need to configure API keys:

Step 1: Check main agent's model configuration

# View main agent's model configuration
cat ~/.openclaw/agents/main/agent/models.json

# View global model providers
cat ~/.openclaw/openclaw.json | grep -A 20 "providers"

Step 2: Choose configuration approach

Option A: Use same model as main agent (recommended)

• New agent can directly use main agent's model configuration
• No additional configuration needed
• Models are shared across agents by default

Option B: Configure new model provider

• Required only if agent needs different model provider
• Add provider to openclaw.json models.providers
• Configure auth-profiles.json for the agent

Step 3: Configure model provider (if needed)

# Add provider to openclaw.json
# Location: ~/.openclaw/openclaw.json

# Example structure:
{
  "models": {
    "providers": {
      "custom-provider": {
        "baseUrl": "https://api.example.com/v1",
        "apiKey": "key_id:secret",
        "api": "openai-completions",
        "models": [...]
      }
    }
  }
}

Step 4: Configure agent-specific auth (if needed)

# Edit auth-profiles.json for the agent
# Location: ~/.openclaw/agents/<agent-name>/agent/auth-profiles.json

# Example structure:
{
  "custom-provider": {
    "apiKey": "key_id:secret",
    "baseUrl": "https://api.example.com/v1"
  }
}

⚠️ IMPORTANT: Model providers vs Channel providers

• Model providers: Configure AI model API keys (OpenAI, Anthropic, custom providers)

  • Location: openclaw.json → models.providers
  • Used for: AI model access
  • Examples: openai, anthropic, custom-maas-api-*

• Channel providers: Configure messaging platform credentials (Feishu, Telegram, Discord)

  • Location: openclaw.json → channels.<provider>
  • Used for: Message delivery
  • Examples: feishu, telegram, discord, whatsapp

Do not confuse these two types of providers!

Common error:

⚠️ Agent failed before reply: No API key found for provider "provider-name"

Solution:

1. Check if provider name matches openclaw.json models.providers
2. Verify API key is configured correctly
3. Check auth-profiles.json for agent-specific configuration
4. Restart OpenClaw Gateway after configuration changes

⚠️ IMPORTANT: Never reuse credentials from main agent!

Error recovery:

• If openclaw agents add fails: Restores from backup and checks syntax
• If auth fails: Verify credentials in auth-profiles.json
• If binding fails: Check channel permissions and network connectivity
• If backup fails: Check write permissions on ~/.openclaw/ directory
• If main agent stops responding: Immediately restore from backup and restart OpenClaw

Common errors and solutions:

Error 1: "No API key found for provider 'provider-name'"

Causes:

• Provider name doesn't match any configured provider in openclaw.json
• Typo in provider name
• Provider not added to models.providers

Solutions:

1. Check provider name in openclaw.json:

   cat ~/.openclaw/openclaw.json | grep -A 10 "providers"

2. Verify provider name spelling (case-sensitive)
3. Add provider to models.providers if needed
4. Restart OpenClaw Gateway after configuration changes

Error 2: "Agent failed before reply"

Causes:

• Agent configuration is invalid
• Workspace files are missing or corrupted
• Model configuration is incorrect

Solutions:

1. Verify workspace files exist:

   ls -la /path/to/workspace/

2. Check agent configuration:

   openclaw agents list

3. Test agent loading:

   openclaw agents test <agent-name>

4. Check OpenClaw logs:

   openclaw logs --follow

Error 3: "Missing required parameter: path (path or file_path)"

Causes:

• Using wrong parameter name in write tool
• Parameter format error in tool call

Solutions:

1. Use correct parameter name: file_path instead of path
2. Verify tool call syntax:

   write:
     file_path: /path/to/file.md
     content: "content here"

3. Check tool documentation for correct parameters

Error 4: "Could not find exact text in file"

Causes:

• Using edit tool with incorrect oldText
• Whitespace differences (spaces vs tabs)
• File already modified by another process

Solutions:

1. Re-read file to get exact content:

   read /path/to/file.md

2. Use unique markers for large sections:

   <!-- SECTION_START -->
   [content]
   <!-- SECTION_END -->

3. Match whitespace exactly (copy from file read)
4. Use smaller oldText for more precise matching
