Xanther Session Engine
Persistent memory and cross-session state management. PRAT enables recursive linking across sessions — your agent never forgets decisions, preferences, or architectural context.
The problem with stateless agents
Every new chat, every new task — your agent starts from zero. It doesn't remember what it tried before, what decisions were made, or what your preferences are. Session Engine fixes that.
Capabilities
Persistent Memory
Your agent remembers past interactions, decisions, and context — even across restarts.
- ▸Long-term memory store
- ▸Contextual recall
- ▸Memory pruning
Cross-Session State
State carries over between sessions so your agent picks up right where it left off.
- ▸Session continuity
- ▸State snapshots
- ▸Rollback support
Decision History
Track every decision your agent made and why — full audit trail for debugging.
- ▸Decision logging
- ▸Reasoning traces
- ▸Conflict resolution
User Preferences
Learn coding style, naming conventions, and architectural preferences over time.
- ▸Style learning
- ▸Convention enforcement
- ▸Adaptive suggestions
Use Cases
Multi-day refactors
Agent remembers what it already explored, what approaches failed, and what's left to do.
Team onboarding
New team members' agents inherit shared knowledge about the codebase and conventions.
Debugging continuity
Pick up a debugging session days later — the agent recalls the full investigation trail.
Style consistency
Agent learns your team's coding patterns and applies them automatically across PRs.
