Persistence

Phase 1: Session History

~/.config/claws/chat/
├── sessions/
│   ├── 2026-01-07-abc123.json
│   └── 2026-01-07-def456.json
└── current.json

• Keep last N sessions (default: 10)
• :chat history - list past sessions
• :chat resume - resume session

Phase 2 (future): Resource Notes

• AI auto-saves important findings per resource
• Show "AI Notes" section in DetailView

Implementation

New Files

• internal/ai/bedrock.go - Converse API wrapper (streaming)
• internal/ai/tools.go - Tool definitions + executor
• internal/ai/session.go - Session persistence
• internal/view/chat_overlay.go - Overlay component
• internal/view/chat_view.go - Fullscreen chat

Key Decisions

• Read-only: List/Get only, no destructive operations
• DAO-based: 163 resources, grows with DAOs
• Model: Configurable (Sonnet/Haiku)

Tasks

• Bedrock Converse API wrapper (streaming)
• Tool definitions + executor
• Context extraction from views
• Chat overlay component
• Fullscreen chat view
• Session persistence
• Config: model, region, max_sessions
• Keybind integration

Open Questions

• Overlay keybind: A? ?a?
• Default model: Sonnet vs Haiku
• Max context tokens to send

Decisions
