"""Warm Session Provisioning — pre-proficient agent sessions.
|
||||
|
||||
Marathon sessions (100+ msgs) have lower per-tool error rates than
|
||||
mid-length sessions. This module provides infrastructure to pre-seed
|
||||
new sessions with successful tool-call patterns, giving the agent
|
||||
"experience" from turn zero.
|
||||
|
||||
Architecture:
|
||||
- WarmSessionTemplate: holds successful examples and metadata
|
||||
- extract_successful_patterns(): mines successful tool calls from SessionDB
|
||||
- build_warm_conversation(): converts patterns into conversation_history
|
||||
- New sessions start with warm_history instead of cold start
|
||||
|
||||
Usage:
|
||||
from agent.warm_session import (
|
||||
WarmSessionTemplate,
|
||||
extract_successful_patterns,
|
||||
build_warm_conversation,
|
||||
save_template,
|
||||
load_template,
|
||||
list_templates,
