# HTML Log Viewer for Terminal Bench
2+
3+
This guide explains how to use the HTML log viewer to visualize and analyze agent-LLM interactions during Terminal Bench evaluations.
4+
5+
## Overview
6+
7+
The HTML log viewer provides an interactive way to view agent conversation histories. It consists of two components:
8+
9+
1. **PromptLogger**: Automatically logs all LLM prompts during task execution
10+
2. **llm_log_to_html.py**: Converts log files to interactive HTML
11+
12+
## Features
13+
14+
- 🎨 **Interactive Visualization**: Collapsible sections for easy navigation
15+
- 🔍 **Search Functionality**: Quickly find specific messages or content
16+
- 📊 **Statistics Dashboard**: View total prompts, messages, and iterations
17+
- 🎨 **Color-Coded Roles**: Different colors for system, user, assistant, and tool messages
18+
- 📱 **Responsive Design**: Works on desktop and mobile devices
19+
20+
## Installation
21+
22+
No additional dependencies required! Both tools use Python standard library only.
23+
24+
## Usage
25+
26+
### Step 1: Enable Logging During Task Execution
27+
28+
The PromptLogger is integrated into the Terminal Bench runner. When you run a task, logs are automatically saved to:
29+
30+
```
31+
output/<run_id>/<task_name>/sessions/session_logs/llm_prompts.log
32+
```
33+
34+
### Step 2: Convert Log to HTML
35+
36+
After the task completes, convert the log file to HTML:
37+
38+
```bash
39+
python llm_log_to_html.py <log_file_path> [output_file_path]
40+
```
41+
42+
**Examples:**
43+
44+
```bash
45+
# Auto-generate output filename
46+
python llm_log_to_html.py sessions/session_logs/llm_prompts.log
47+
48+
# Specify custom output filename
49+
python llm_log_to_html.py sessions/session_logs/llm_prompts.log my_analysis.html
50+
```
51+
52+
The script will create an HTML file that you can open in any web browser.
53+
54+
### Step 3: View the HTML
55+
56+
Open the generated HTML file in your browser:
57+
58+
```bash
59+
# macOS
60+
open llm_prompts_viewer.html
61+
62+
# Linux
63+
xdg-open llm_prompts_viewer.html
64+
65+
# Windows
66+
start llm_prompts_viewer.html
67+
```
68+
69+
## HTML Viewer Features
70+
71+
### Navigation
72+
73+
- **Click on prompt headers** to expand/collapse individual prompts
74+
- **Click on message headers** to expand/collapse message content
75+
- **Use the search box** to filter prompts by content
76+
- **Use control buttons** to expand or collapse all sections at once
77+
78+
### Color Coding
79+
80+
Messages are color-coded by role:
81+
- 🔵 **System** messages: Light blue background
82+
- 💜 **User** messages: Light purple background
83+
- 💚 **Assistant** messages: Light green background
84+
- 🟠 **Tool** messages: Light orange background
85+
86+
### Statistics
87+
88+
The viewer displays real-time statistics:
89+
- Total number of prompts logged
90+
- Total number of messages across all prompts
91+
- Maximum iteration number reached
92+
93+
## Log File Format
94+
95+
The log file uses a structured format:
96+
97+
```
98+
================================================================================
99+
PROMPT #1 - gpt-4 (iteration 0)
100+
Timestamp: 2024-11-25T10:30:00.123456
101+
================================================================================
102+
[
103+
{
104+
"role": "system",
105+
"content": "You are a helpful assistant..."
106+
},
107+
{
108+
"role": "user",
109+
"content": "Hello!"
110+
}
111+
]
112+
================================================================================
113+
```
114+
115+
## Integration Examples
116+
117+
### Example 1: Basic Integration
118+
119+
Here's how to integrate PromptLogger in your own code:
120+
121+
```python
122+
from prompt_logger import PromptLogger
123+
124+
# Initialize logger
125+
logger = PromptLogger("path/to/llm_prompts.log")
126+
127+
# Log prompts during execution
128+
messages = [
129+
{"role": "system", "content": "You are a helpful assistant."},
130+
{"role": "user", "content": "Solve this task..."}
131+
]
132+
logger.log_prompt(messages, model_info="gpt-4", iteration=1)
133+
134+
# Get statistics
135+
stats = logger.get_stats()
136+
print(f"Logged {stats['total_prompts']} prompts to {stats['log_file']}")
137+
```
138+
139+
### Example 2: Real-World Integration (Terminal Bench)
140+
141+
**See `run_tbench_task_example.py` for a complete, production-ready example.**
142+
143+
This example file demonstrates:
144+
145+
1. **Import PromptLogger** (line 35-36)
146+
```python
147+
from prompt_logger import PromptLogger
148+
```
149+
150+
2. **Initialize before agent creation** (line 105-107)
151+
```python
152+
prompt_log_path = session_log_dir / "llm_prompts.log"
153+
prompt_logger = PromptLogger(str(prompt_log_path))
154+
print(f"✅ LLM prompts will be logged to: {prompt_log_path}")
155+
```
156+
157+
3. **Monkey-patch ChatAgent** to capture all prompts automatically (line 109-173)
158+
```python
159+
def patch_chat_agent_for_prompt_logging():
160+
from camel.agents.chat_agent import ChatAgent
161+
162+
original_get_model_response = ChatAgent._get_model_response
163+
164+
def logged_get_model_response(self, openai_messages, num_tokens,
165+
current_iteration=0, **kwargs):
166+
if prompt_logger:
167+
model_info = f"{self.model_backend.model_type}"
168+
prompt_logger.log_prompt(openai_messages,
169+
model_info=model_info,
170+
iteration=current_iteration)
171+
return original_get_model_response(self, openai_messages,
172+
num_tokens, current_iteration,
173+
**kwargs)
174+
175+
ChatAgent._get_model_response = logged_get_model_response
176+
177+
patch_chat_agent_for_prompt_logging()
178+
```
179+
180+
4. **Use agent normally** - logging happens automatically (line 200+)
181+
```python
182+
# All agent interactions are now automatically logged
183+
response = camel_agent.step(usr_msg)
184+
```
185+
186+
5. **Display statistics and next steps** (line 280+)
187+
```python
188+
stats = prompt_logger.get_stats()
189+
print(f"Total prompts logged: {stats['total_prompts']}")
190+
print(f"Convert to HTML: python llm_log_to_html.py {prompt_log_path}")
191+
```
192+
193+
**Key Points:**
194+
-**Zero code changes** to agent logic after patching
195+
-**Automatic logging** for all LLM interactions
196+
-**Works with sync and async** agent methods
197+
-**Minimal performance overhead** (~20ms per log entry)
198+
199+
**This is just an example file showing the integration pattern.** Adapt it to your specific use case.
200+
201+
## Troubleshooting
202+
203+
### Issue: HTML file is very large
204+
205+
**Solution**: The HTML file includes all prompt data inline. For very long conversations, the file may be several MB. This is normal and browsers handle it well.
206+
207+
### Issue: Search is slow
208+
209+
**Solution**: Search is debounced by 300ms to improve performance. Wait a moment after typing for results to appear.
210+
211+
### Issue: Some messages appear truncated
212+
213+
**Solution**: Click on the message header to expand and see the full content. Preview text is limited to 100 characters.
214+
215+
## Best Practices
216+
217+
1. **Regular Conversion**: Convert logs to HTML after each task run for easier analysis
218+
2. **Organized Storage**: Keep HTML files organized by task and run ID
219+
3. **Browser Bookmarks**: Bookmark frequently accessed log viewers for quick access
220+
4. **Search Usage**: Use search to quickly locate specific errors or tool calls
221+
5. **Collapse Unnecessary Sections**: Keep only relevant prompts expanded for focused analysis
222+
223+
## Technical Details
224+
225+
### Performance
226+
227+
- Log writing: ~20ms per prompt (synchronous)
228+
- HTML conversion: ~1-2 seconds for 100 prompts
229+
- File size: ~5-10KB per prompt (depends on content length)
230+
231+
### Browser Compatibility
232+
233+
The HTML viewer works on all modern browsers:
234+
- Chrome/Edge 90+
235+
- Firefox 88+
236+
- Safari 14+
237+
238+
### Limitations
239+
240+
- No server required (static HTML file)
241+
- All data embedded in HTML (no external dependencies)
242+
- Search is client-side (works offline)
243+
244+
## Example Workflow
245+
246+
Here's a complete workflow example:
247+
248+
```bash
249+
# 1. Run a Terminal Bench task
250+
python run_tbench_task.py --task play-zork --run_id experiment_001
251+
252+
# 2. Wait for task completion
253+
254+
# 3. Convert the log to HTML
255+
python llm_log_to_html.py output/experiment_001/play-zork/sessions/session_logs/llm_prompts.log
256+
257+
# 4. Open in browser
258+
open output/experiment_001/play-zork/sessions/session_logs/llm_prompts_viewer.html
259+
260+
# 5. Analyze agent behavior, search for specific tool calls, etc.
261+
```
