Implement two-stage content codec: truncate oversized agent messages (48KB head + 12KB tail + marker, idempotent, never user messages) and compress message content JSON ≥256 bytes via zstd with fallback. - contentCodec.ts: new codec with truncation and compression routines - messages.ts: wire codec into addMessage (truncate+compress), copyMessageToSession (lossless), toStoredMessage (decode both formats) - index.ts: schema version 15→16 with no-op migration (enforces schema match on downgrade, no DDL change) - codexDesktop.ts: pass content through idempotent truncation for canonical comparison in transcript-import - cleanup-sessions.ts: decode compressed rows, replace full-scan with per-session batched scan (LIMIT 50) stopping at first user message - compact-db.ts: new offline compactor that retroactively applies truncate+compress+VACUUM to existing DBs; guards against schema version mismatch, symlink aliasing, and handles re-runs - Tests: contentCodec round-trip + truncation + idempotence + legacy decode; messages integration (compressed/truncated round-trip); migration tests updated to version 16 - README.md: document codec and both maintenance scripts Measured on 2.26GB production DB: 2159MB→768MB (-64%) in 12s, 748k messages intact, integrity verified.
HAPI
Run official Claude Code / Codex / Cursor Agent / Grok Build / OpenCode sessions locally and control them remotely through a Web / PWA / Telegram Mini App.
Why HAPI? HAPI is a local-first alternative to Happy. See Why Not Happy? for the key differences.
Features
- Seamless Handoff - Work locally, switch to remote when needed, switch back anytime. No context loss, no session restart.
- Native First - HAPI wraps your AI agent instead of replacing it. Same terminal, same experience, same muscle memory.
- AFK Without Stopping - Step away from your desk? Approve AI requests from your phone with one tap.
- Your AI, Your Choice - Claude Code, Codex, Cursor Agent, Grok Build, OpenCode—different agents, one unified workflow.
- Terminal Anywhere - Run commands from your phone or browser, directly connected to the working machine.
- Voice Control - Talk to your AI agent hands-free using the built-in voice assistant.
- Workspace Browser - Opt-in via one or more
hapi runner start --workspace-root <path>flags: browse scoped file trees from the web and start sessions in allowed subdirectories.

Getting Started
npx @twsxtd/hapi hub --relay # start hub with E2E encrypted relay
npx @twsxtd/hapi # run claude code
hapi server remains supported as an alias.
The terminal will display a URL and QR code. Scan the QR code with your phone or open the URL to access.
The relay uses WireGuard + TLS for end-to-end encryption. Your data is encrypted from your device to your machine.
