Hot Claude Session Implementation Complete
Fully integrated hot Claude sessions into konsole for instant subsequent responses
Output
🔥 Hot Claude Session Implementation Complete
Hot sessions keep Claude processes alive between prompts for instant subsequent responses (~0ms spawn time vs 3-5s cold start).
Key Changes
konsole/src/ ├── hot-claude.ts # Hot session manager with pool ├── stream.ts # +processHotPrompt() function ├── main.ts # +/sessions/:id/hot-prompt route ├── config.ts # +hotPoolSize config option └── types.ts # +"hot-claude" log category
Architecture
Cold Start (current): Client → POST /prompt → spawn claude → wait 3-5s → response Hot Session (new): Client → POST /hot-prompt → reuse process → instant → response ↑ Claude stays alive between prompts
API Endpoints
POST /sessions/:id/hot-prompt | Send prompt via hot session |
GET /hot/status | Pool status (poolSize, targetSize, activeSessions) |
Configuration
KONSOLE_HOT_POOL_SIZE=2 # Pre-warm 2 sessions (0 = on-demand)
Test Results ✅
✓ Hot Claude Session - Multi-turn Memory Test (12s) - Spawned Claude with --input-format stream-json - Sent "Remember 42" → Got "OK" - Sent "What number?" → Got "42" (same session ID!) - Process kept alive between prompts
