* fix(cli): buffer Pi prompts until RPC startup ready A prompt POSTed immediately after spawn (a supported handoff pattern used by hapi-ping-peer and intake scripts) could reach `pi --mode rpc` before its `new_session`/`get_state` startup finished, wedging the turn: `agent_start` then silence, no tool calls. The socket goes `active` (spawn success) well before Pi's session is initialized, so `active` is not a safe ready signal for Pi. Gate outbound prompt/steer sends behind a startup ready gate on PiSession: `runWhenReady()` delivers immediately once ready, else buffers FIFO; `markReady()` fires on the first `get_state` response (the signal that persists `metadata.piSessionId`, which working callers already wait for) and drains the buffer in order. A 30s unref'd fallback timer force-drains if `get_state` never lands, degrading to prior send-anyway behaviour rather than swallowing the message forever. Fixes #1143 Co-authored-by: Cursor <cursoragent@cursor.com> * fix(cli): honor cancel-queued-message for buffered Pi prompts Addresses the MAJOR review finding on the startup ready-buffer: while a prompt is held behind runWhenReady, the hub can send cancel-queued-message for its localId. Pi registered no onCancelQueuedMessage handler, so ApiSessionClient acked removed:false, the hub marked the row invoked, yet the buffered closure still drained on get_state and fired the cancelled prompt. Carry the localId with each buffered send and add PiSession.cancelBufferedMessage, then register apiSession.onCancelQueuedMessage so a cancel drops the still-buffered prompt (returns true) instead of sending it. Once drained to Pi it cannot be recalled — returns false, matching the other agents' queue.cancelByLocalId best-effort semantics.

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.
