Junmo KimandGitHub 223be6d60f fix(cli): don't lose the queued message when a remote launch fails (#1058)
* fix(cli): cap and back off consecutive remote launch failures

claudeRemoteLauncher's respawn loop retried claudeRemote() immediately
on every throw with no backoff or limit. A deterministic launch
failure (bad auth, invalid model/args, spawn failure) respawned in a
tight loop instead of giving up, hammering the same failure forever.

Track whether onReady() fired at least once per attempt to tell an
immediate/deterministic failure apart from a failure after real
progress, back off between immediate-failure retries, and after 3
consecutive immediate failures drop the message that keeps triggering
them and reset the streak, instead of respawning forever. The session
keeps running so a later, unrelated message still gets its own budget.
The streak reset on a non-throwing attempt is itself gated on having
reached onReady, not applied unconditionally -- otherwise a message
that keeps getting parked and re-picked-up on alternating attempts
(e.g. an isolated command hitting the same deterministic failure)
would reset the streak every other attempt and the cap would never
fire.

* fix(cli): restore queued message when remote launch fails before delivery

MessageQueue2.collectBatch() acks a message (fires onBatchConsumed,
which the hub uses to mark it consumed) at dequeue time, before the
message ever reaches the SDK. If claudeRemote() then throws before
onReady -- e.g. the process dies right after picking up the message --
the catch block only logged and retried, so the message vanished: the
hub already thinks it was delivered, but the CLI never acted on it.

Track the message returned from nextMessage() (whether freshly
dequeued or held in `pending` across a mode change) as in-flight until
the next onReady confirms it was handled, and restore it to the front
of the queue (preserving isolation via unshiftIsolated when needed) if
the attempt throws and will be retried. Restoring happens even if the
throw races with a user-initiated switch/exit, so a message is not
silently dropped by that unrelated shutdown either.

When the immediate-failure cap from the previous commit is reached,
the in-flight message is dropped instead of restored: unshifting it
back would just feed it into another immediate failure on the very
next attempt, storming again. This mirrors
cursorLegacyRemoteLauncher's existing drop-and-reset policy on its own
consecutive-failure cap.

* fix(cli): preserve localId when restoring a failed message batch

MessageQueue2.collectBatch() already collects each queue item's
localId (it fires onBatchConsumed with the full list to ack them), but
only exposed the joined `message` string to callers, discarding the
per-item localIds and their original boundaries in the process.

When claudeRemoteLauncher restores a dequeued-but-undelivered batch
after a launch failure, it re-added the joined string as a single new
queue item with no localId, orphaning the retried prompt from the hub
row(s) it originated from (and from cancel-by-localId).

Expose the pre-join `items` breakdown (message + localId per item)
alongside the existing joined `message` field on
collectBatch()/waitForMessagesAndGetAsString() -- purely additive, so
the other callers of waitForMessagesAndGetAsString() (grok, kimi,
opencode, cursor, codex, runAgentSession) are unaffected. On restore,
unshift each original item individually in reverse order, so the
localId and relative order of a multi-message batch are both
preserved instead of just the first item's.

* fix(cli): reset immediate-failure streak on a delivered non-onReady success

claudeRemote.ts's /clear handling delivers the queued message to the
SDK, then calls onSessionReset()/onCompletionEvent() and returns
successfully without ever calling onReady(). The success-path streak
reset only cleared on reachedReadyThisAttempt, so a successful /clear
between two unrelated immediate launch failures did not reset the
streak: an unrelated message's very next failure could hit the
3-in-a-row cap after just 1 failure, and the resulting banner would
misreport "3 times in a row".

Track whether nextMessage() actually handed a message to the SDK this
attempt (deliveredMessageThisAttempt), separately from whether the
attempt reached onReady, and reset the streak on either signal. The
livelock-prone case this guards against (a message parked into
`pending` and the attempt returning without ever delivering anything)
leaves both flags false, so it still does not reset the streak.

hapi CLI

Run Claude Code, Codex, Cursor Agent, Grok Build, or OpenCode sessions from your terminal and control them remotely through the hapi hub.

What it does

  • Starts Claude Code sessions and registers them with hapi-hub.
  • Starts Codex mode for OpenAI-based sessions.
  • Starts Cursor Agent mode for Cursor CLI sessions.
  • Starts Grok Build locally or via ACP for remote sessions.
  • Starts Gemini mode via ACP (Anthropic Code Plugins).
  • Starts OpenCode mode via ACP and its plugin hook system.
  • Provides an MCP stdio bridge for external tools.
  • Manages a background runner for long-running sessions.
  • Includes diagnostics and auth helpers.

Typical flow

  1. Start the hub and set env vars (see ../hub/README.md).
  2. Set the same CLI_API_TOKEN on this machine or run hapi auth login.
  3. Run hapi to start a session.
  4. Use the web app or Telegram Mini App to monitor and control.

Commands

Session commands

  • hapi - Start a Claude Code session (passes through Claude CLI flags). See src/index.ts.
  • hapi codex - Start Codex mode. See src/codex/runCodex.ts.
  • hapi codex resume <sessionId> - Resume existing Codex session.
  • hapi cursor - Start Cursor Agent mode. See src/cursor/runCursor.ts. Supports hapi cursor resume <chatId>, hapi cursor --continue, --mode plan|ask, --yolo, --model. Local and remote modes supported; remote uses agent -p with stream-json.
  • hapi grok - Start Grok Build mode. See src/grok/runGrok.ts.
  • hapi gemini - Start Gemini mode via ACP. See src/agent/runners/runAgentSession.ts. Note: Gemini runs in remote mode only; it waits for messages from the hub UI/Telegram.
  • hapi opencode - Start OpenCode mode via ACP. See src/opencode/runOpencode.ts. Note: OpenCode supports local and remote modes; local mode streams via OpenCode plugins.
  • hapi resume [sessionId] - List resumable sessions for this machine or resume one locally.

Resume a remote session locally

hapi resume
hapi resume <session-id>

hapi resume lists resumable sessions for the current machine. hapi resume <session-id> hands off an active remote session and opens the same HAPI session in the local terminal.

Authentication

  • hapi auth status - Show authentication configuration and token source.
  • hapi auth login - Interactively enter and save CLI_API_TOKEN.
  • hapi auth logout - Clear saved credentials.

See src/commands/auth.ts.

Runner management

  • hapi runner start - Start runner as detached process.
  • hapi runner stop - Stop runner gracefully.
  • hapi runner status - Show runner diagnostics.
  • hapi runner list - List active sessions managed by runner.
  • hapi runner stop-session <sessionId> - Terminate specific session.
  • hapi runner logs - Print path to latest runner log file.

Both start and start-sync accept repeatable --workspace-root <path> (or --workspace-root=<path>). When set:

  • The web /browse page surfaces scoped file trees rooted at those paths.
  • The runner refuses list-directory and spawn-session requests for paths outside the configured roots.
  • ~ and ~/foo are expanded.

Omitting the flag keeps the legacy behavior: no scoping, no /browse feature.

See src/runner/run.ts.

Diagnostics

  • hapi doctor - Show full diagnostics (version, runner status, logs, processes).
  • hapi doctor clean - Kill runaway HAPI processes.

See src/ui/doctor.ts.

Other

  • hapi mcp - Start MCP stdio bridge. See src/codex/happyMcpStdioBridge.ts.
  • hapi hub - Start the bundled hub (single binary workflow).
  • hapi server - Alias for hapi hub.

Optional

  • HAPI_HOME - Config/data directory (default: ~/.hapi).
  • HAPI_EXPERIMENTAL - Enable experimental features (true/1/yes).
  • HAPI_EXTRA_HEADERS_JSON - JSON object of extra headers to send on CLI → hub requests, e.g. {"Cookie":"CF_Authorization=..."}. Can also be set as the extraHeaders object in ~/.hapi/settings.json (environment variable wins).
  • HAPI_CLAUDE_PATH - Path to a specific claude executable.
  • HAPI_HTTP_MCP_URL - Default MCP target for hapi mcp.

Runner

  • HAPI_RUNNER_HEARTBEAT_INTERVAL - Heartbeat interval in ms (default: 60000).

  • HAPI_WORKTREE_NAME - Worktree name.
  • HAPI_WORKTREE_PATH - Full worktree path.
  • HAPI_WORKTREE_CREATED_AT - Creation timestamp (ms).

Storage

Data is stored in ~/.hapi/ (or $HAPI_HOME):
