+# Session Templates for Code-First Seeding
+
+## Overview
+
+Session templates pre-seed new sessions with successful tool call patterns from previous sessions. Based on research finding that code-heavy sessions (execute_code dominant in first 30 turns) improve over time, while file-heavy sessions degrade.
+
+## Key Concepts
+
+### Task Type Classification
+
+Sessions are classified into four types based on tool call patterns:
+
+- **CODE**: execute_code dominant (>60% of tool calls)
+- **FILE**: file operations dominant (read_file, write_file, patch, search_files)
+- **RESEARCH**: research tools dominant (web_search, web_fetch, browser_navigate)
+- **MIXED**: no dominant type (<60% for any category)
+
+### Template Structure
+
+Each template contains:
+- **Name**: Unique identifier
+- **Task Type**: CODE, FILE, RESEARCH, or MIXED
+- **Examples**: List of successful tool calls with arguments and results
+- **Description**: Human-readable description
+- **Tags**: Optional categorization tags
+- **Usage Count**: How many times the template has been used
+- **Source Session ID**: Session from which template was extracted
+
+## Usage
+
+### CLI Interface
+
+```bash
+# List all templates
+python -m tools.session_templates list
+
+# List only code templates
+python -m tools.session_templates list --type code
+
+# List templates with specific tags
+python -m tools.session_templates list --tags "python,testing"
+
+# Create template from session
+python -m tools.session_templates create 20260413_123456_abc123 --name my-code-template
+
+# Create template with description and tags
+python -m tools.session_templates create 20260413_123456_abc123 \
+    --name my-template \
+    --type code \
+    --description "Python development template" \
+    --tags "python,development"
+
+# Delete template
+python -m tools.session_templates delete my-template
+
+# Show statistics
+python -m tools.session_templates stats
+```
+
+### Programmatic Usage
+
+```python
+from tools.session_templates import SessionTemplates, TaskType
+
+# Create template manager
+templates = SessionTemplates()
+
+# Get template for code tasks
+template = templates.get_template(TaskType.CODE)
+
+# Inject template into messages
+messages = [
+    {"role": "system", "content": "You are a helpful assistant."},
+    {"role": "user", "content": "Help me write some code"}
+]
+
+updated_messages = templates.inject_into_messages(template, messages)
+
+# Create template from session
+template = templates.create_template(
+    session_id="20260413_123456_abc123",
+    name="my-template",
+    task_type=TaskType.CODE,
+    max_examples=10,
+    description="My template",
+    tags=["python", "development"]
+)
+
+# List templates
+code_templates = templates.list_templates(task_type=TaskType.CODE)
+all_templates = templates.list_templates()
+
+# Get statistics
+stats = templates.get_template_stats()
+print(f"Total templates: {stats['total']}")
+print(f"Total examples: {stats['total_examples']}")
+```
+
+## Implementation Details
+
+### Template Extraction
+
+1. Query SQLite database for session messages
+2. Extract tool calls from assistant messages
+3. Match tool calls with their results from tool responses
+4. Create ToolCallExample objects with arguments and results
+
+### Template Injection
+
+1. Create system message about template
+2. Add assistant messages with tool calls from template
+3. Add tool responses with results
+4. Insert after existing system messages
+5. Update template usage count
+
+### Storage
+
+Templates are stored as JSON files in `~/.hermes/session-templates/`:
+
+```json
+{
+  "name": "code_python_20260413",
+  "task_type": "code",
+  "examples": [
+    {
+      "tool_name": "execute_code",
+      "arguments": {"code": "print('hello world')"},
+      "result": "hello world",
+      "success": true,
+      "turn_number": 0
+    }
+  ],
+  "description": "Python development template",
+  "created_at": 1712345678.0,
+  "usage_count": 5,
+  "source_session_id": "20260413_123456_abc123",
+  "tags": ["python", "development"]
+}
+```
+
+## Research Background
+
+### Finding
+
+Code-heavy sessions (execute_code dominant in first 30 turns) improve over time. File-heavy sessions (search/read/patch) degrade. The key is deterministic feedback loops, not arbitrary context.
+
+### Hypothesis
+
+Pre-seeding new sessions with successful tool call patterns establishes feedback loops early, leading to:
+- Lower error rate in first 30 turns
+- Faster time to first success
+- Fewer total errors
+- Better tool call diversity
+
+### Experiment Design
+
+A/B test: cold start vs code-seeded start on same task. Measure:
+- Error rate in first 30 turns
+- Time to first success
+- Total errors
+- Tool call diversity
+
+## Best Practices
+
+### Template Creation
+
+1. **Extract from successful sessions**: Only use sessions with high success rates
+2. **Limit examples**: 5-10 examples per template is optimal
+3. **Use descriptive names**: Include task type and context in name
+4. **Add tags**: Use tags for categorization and filtering
+5. **Update regularly**: Create new templates from recent successful sessions
+
+### Template Usage
+
+1. **Match task type**: Use templates that match the expected task type
+2. **Don't over-inject**: One template per session is sufficient
+3. **Monitor effectiveness**: Track whether templates improve performance
+4. **Clean up old templates**: Remove templates that are no longer effective
+
+## Troubleshooting
+
+### No Templates Found
+
+- Check if `~/.hermes/session-templates/` directory exists
+- Verify session database exists at `~/.hermes/state.db`
+- Check if session has successful tool calls
+
+### Template Injection Not Working
+
+- Verify template has examples
+- Check if messages list is not empty
+- Ensure template is properly loaded
+
+### Extraction Fails
+
+- Verify session ID exists in database
+- Check if session has tool calls
+- Ensure database is not corrupted
+
+## Future Enhancements
+
+1. **Automatic template creation**: Create templates automatically from successful sessions
+2. **Template optimization**: Use ML to optimize template selection
+3. **Cross-session learning**: Share templates across users (with privacy controls)
+4. **Template versioning**: Track template effectiveness over time
+5. **Dynamic template adjustment**: Adjust templates based on task complexity
