-# Template Error Fix: LoggingUndefined Not JSON Serializable
-
-## Error Message
-```
-Sorry, I had a problem with my template: TypeError: Type is not JSON serializable: LoggingUndefined
-```
-
-## Root Cause
-
-The error occurs in the template rendering logic in `custom_components/llama_conversation/entity.py:662`. When your prompt template references a variable that doesn't exist, Jinja2 returns a special `LoggingUndefined` object. When Home Assistant tries to process this undefined value (during string formatting or JSON serialization), it fails because `LoggingUndefined` is not JSON serializable.
-
-## The Problem Location
-
-### In Your Template
-The problematic line in your prompt template is:
-
-```jinja2
-Tools: {{ tools | to_json }}
-```
-
-### Why It Fails
-
-The `tools` variable is **only available** when **"Enable Legacy Tool Calling"** is enabled in your configuration.
-
-Looking at the code (`entity.py:645-655`), `tools` is only added to the template variables when `enable_legacy_tool_calling` is `True`:
-
-```python
-if enable_legacy_tool_calling:
-    if llm_api:
-        # ... tools are added here
-        render_variables["tools"] = tools
-```
-
-When this setting is disabled (which is the default), the template tries to access `{{ tools }}`, gets a `LoggingUndefined` object, and then `to_json` fails trying to serialize it.
-
-## Available Template Variables
-
-When rendering your prompt template, only these variables are available:
-
-- `devices` - List of exposed devices
-- `formatted_devices` - String representation of devices
-- `response_examples` - ICL examples (if enabled)
-- `tool_call_prefix` / `tool_call_suffix` - Tool call markers
-- `tools` / `formatted_tools` - Available tools (⚠️ **only if legacy calling enabled**)
-
-## Solutions
-
-### Option 1: Enable Legacy Tool Calling (Quick Fix)
-
-1. Go to your LLaMA Conversation integration settings
-2. Find the "Enable Legacy Tool Calling" option
-3. Enable it
-4. Save and restart
-
-### Option 2: Fix the Template (Recommended)
-
-Replace the problematic line:
-
-```jinja2
-Tools: {{ tools | to_json }}
-```
-
-With one of these conditional versions:
-
-#### Using `is defined` check:
-```jinja2
-{% if tools is defined %}Tools: {{ tools | to_json }}{% endif %}
-```
-
-#### Using `default()` filter:
-```jinja2
-Tools: {{ tools | default("No tools configured") | to_json }}
-```
-
-#### Using `default()` with empty list:
-```jinja2
-Tools: {{ tools | default([]) | to_json }}
-```
-
-## Complete Fixed Template
-
-```jinja2
-You are 'Al', a helpful AI Assistant that controls the devices in a house. Complete the following task as instructed with the information provided only.
-The current time and date is {{ (as_timestamp(now()) | timestamp_custom("%I:%M %p on %A %B %d, %Y", True, "")) }}
-{% if tools is defined %}Tools: {{ tools | to_json }}{% endif %}
-Devices:
-{% for device in devices | selectattr('area_id', 'none'): %}
-{{ device.entity_id }} '{{ device.name }}' = {{ device.state }}{{ ([""] + device.attributes) | join(";") }}
-{% endfor %}
-{% for area in devices | rejectattr('area_id', 'none') | groupby('area_name') %}
-## Area: {{ area.grouper }}
-{% for device in area.list %}
-{{ device.entity_id }} '{{ device.name }}' = {{ device.state }};{{ device.attributes | join(";") }}
-{% endfor %}
-{% endfor %}
-{% for item in response_examples %}
-{{ item.request }}
-{{ item.response }}
-<functioncall> {{ item.tool | to_json }}
-{% endfor %}
-```
-
-## Prevention
-
-To avoid this error in the future:
-
-1. **Always check if optional variables are defined** before using them
-2. **Use the `default()` filter** for variables that might not exist
-3. **Stick to documented variables** listed in the integration documentation
-4. **Test templates** after making changes
-
-## Common Template Mistakes
-
-❌ **Wrong:**
-```jinja2
-{{ some_typo }}              # Undefined variable
-{{ devises }}                # Typo - should be "devices"
-{{ device.missing_attr }}    # Attribute doesn't exist
-{{ tools | to_json }}        # Not always available
-```
-
-✅ **Correct:**
-```jinja2
-{{ devices }}                           # Defined variable
-{{ tools | default([]) }}               # With fallback
-{% if tools is defined %}{{ tools }}{% endif %}  # With check
-```

-- `custom_components/llama_conversation/entity.py:645-655` - Conditional `tools` variable
-
-## Additional Notes
-
-The `tools` variable is only populated when:
-1. Legacy tool calling is enabled (`CONF_ENABLE_LEGACY_TOOL_CALLING = True`)
-2. An LLM API is configured (`llm_api` is not `None`)
-
-If you need tools in your template, ensure these conditions are met or use conditional checks as shown above.
