Agent Defaults

The agents.defaults section configures the default behavior for all agents in PicoClaw.

​
Configuration Structure

{
  "agents": {
    "defaults": {
      "workspace": "~/.picoclaw/workspace",
      "restrict_to_workspace": true,
      "allow_read_outside_workspace": false,
      "model_name": "gpt4",
      "max_tokens": 8192,
      "temperature": 0.7,
      "max_tool_iterations": 20,
      "max_media_size": 20971520
    }
  }
}

​
Configuration Options

​
workspace

Type: string
Default: ~/.picoclaw/workspace
Environment: PICOCLAW_AGENTS_DEFAULTS_WORKSPACE Working directory where the agent operates. All agent data is stored here: 
~/.picoclaw/workspace/
├── sessions/          # Conversation history
├── memory/           # Long-term memory
├── state/            # Persistent state
├── cron/             # Scheduled jobs
├── skills/           # Custom skills
├── AGENTS.md         # Agent behavior guide
├── HEARTBEAT.md      # Periodic tasks
├── IDENTITY.md       # Agent identity
└── USER.md           # User preferences

​
restrict_to_workspace

Type: boolean
Default: true
Environment: PICOCLAW_AGENTS_DEFAULTS_RESTRICT_TO_WORKSPACE When enabled, restricts agent file and command access to the workspace directory only. Protected tools:
  • read_file - Only files within workspace
  • write_file - Only files within workspace
  • list_dir - Only directories within workspace
  • edit_file - Only files within workspace
  • append_file - Only files within workspace
  • exec - Command paths must be within workspace
Security example: 
{
  "agents": {
    "defaults": {
      "workspace": "~/.picoclaw/workspace",
      "restrict_to_workspace": true
    }
  }
}
With this enabled, the agent cannot access /etc/passwd or any files outside the workspace.
Setting restrict_to_workspace: false allows the agent to access any path on your system. Only use this in controlled environments.

​
allow_read_outside_workspace

Type: boolean
Default: false
Environment: PICOCLAW_AGENTS_DEFAULTS_ALLOW_READ_OUTSIDE_WORKSPACE When enabled (and restrict_to_workspace is true), allows read-only access outside the workspace but still restricts writes and execution.

​
model_name

Type: string
Default: "" (uses first configured model)
Environment: PICOCLAW_AGENTS_DEFAULTS_MODEL_NAME The model to use for agent operations. Must match a model_name from your model_list configuration. 
{
  "agents": {
    "defaults": {
      "model_name": "claude-sonnet-4.6"
    }
  },
  "model_list": [
    {
      "model_name": "claude-sonnet-4.6",
      "model": "anthropic/claude-sonnet-4.6",
      "api_key": "sk-ant-..."
    }
  ]
}

​
max_tokens

Type: integer
Default: 32768
Environment: PICOCLAW_AGENTS_DEFAULTS_MAX_TOKENS Maximum number of tokens the model can generate in a single response. 
{
  "agents": {
    "defaults": {
      "max_tokens": 8192
    }
  }
}
Different models have different context limits. GPT-5.2 supports 128K tokens, while some models are limited to 8K.

​
temperature

Type: float (0.0 - 2.0)
Default: null (uses provider default, typically 0.7)
Environment: PICOCLAW_AGENTS_DEFAULTS_TEMPERATURE Controls randomness in model responses:
  • 0.0 - Deterministic, focused responses
  • 0.7 - Balanced creativity and focus (recommended)
  • 1.0 - More creative and varied
  • 2.0 - Highly random and creative
{
  "agents": {
    "defaults": {
      "temperature": 0.7
    }
  }
}

​
max_tool_iterations

Type: integer
Default: 50
Environment: PICOCLAW_AGENTS_DEFAULTS_MAX_TOOL_ITERATIONS Maximum number of tool calls the agent can make in a single conversation turn. This prevents infinite loops and controls execution cost: 
{
  "agents": {
    "defaults": {
      "max_tool_iterations": 20
    }
  }
}
If the agent reaches this limit, it will respond with current progress and stop.

​
max_media_size

Type: integer (bytes)
Default: 20971520 (20 MB)
Environment: PICOCLAW_AGENTS_DEFAULTS_MAX_MEDIA_SIZE Maximum size for uploaded media files (images, audio, documents). 
{
  "agents": {
    "defaults": {
      "max_media_size": 10485760  // 10 MB
    }
  }
}

​
Model Fallbacks

You can configure fallback models that PicoClaw will try if the primary model fails: 
{
  "agents": {
    "defaults": {
      "model_name": "gpt4",
      "model_fallbacks": ["claude-sonnet-4.6", "gemini-2.0-flash"]
    }
  }
}
PicoClaw will:
  1. Try gpt4 first
  2. If it fails, try claude-sonnet-4.6
  3. If that fails, try gemini-2.0-flash
  4. If all fail, return an error

​
Image Model Configuration

Configure a separate model for vision/image tasks: 
{
  "agents": {
    "defaults": {
      "model_name": "gpt4",
      "image_model": "gpt-5.2-vision",
      "image_model_fallbacks": ["claude-opus-4.5"]
    }
  }
}

​
Security Best Practices

  1. Keep workspace restrictions enabled in production
  2. Set appropriate max_tool_iterations to prevent runaway costs
  3. Use dedicated workspaces for different use cases
  4. Limit max_media_size to prevent abuse

​
Environment Variable Examples

# Override model
PICOCLAW_AGENTS_DEFAULTS_MODEL_NAME=claude-sonnet-4.6 picoclaw agent

# Increase token limit
PICOCLAW_AGENTS_DEFAULTS_MAX_TOKENS=16384 picoclaw agent

# Disable workspace restrictions (not recommended)
PICOCLAW_AGENTS_DEFAULTS_RESTRICT_TO_WORKSPACE=false picoclaw agent

# Set custom workspace
PICOCLAW_AGENTS_DEFAULTS_WORKSPACE=/custom/workspace picoclaw agent
