Mohamed Boudra f539ccf1c0 Recover a dead host connection within seconds of returning to the foreground (#9086)
* fix(client): recover a dead connection within seconds of returning to the foreground

A socket that died while the OS had JS suspended stays OPEN and keeps accepting
sends, so nothing but inbound frames can prove it alive. Since #8651 the
foreground check rode the regular heartbeat: a 15 s window, dedupe onto a probe
that straddled the suspension, misses from before background carried over, and
a 1.5 s backoff after teardown. Measured at the transport: 40 s to tear down and
41.5 s to reconnect, with 15 s to 30 s variations depending on what was in
flight when the app was suspended.

Foreground now starts a fresh cycle inside the same heartbeat owner: two 5 s
windows back to back, then teardown and an immediate reconnect. An outstanding
heartbeat probe is dropped without a miss because it measured the suspension,
not the socket; a latency measurement keeps its own deadline and is shared.
Repeated foreground events join the running cycle instead of restarting it.
The rule that any validated inbound frame voids a window is unchanged, so a
slow multi-frame transfer still survives, and after any progress the heartbeat
returns to its 10 s / 15 s cadence. Ordinary heartbeat teardowns keep their
backoff; only the foreground cycle reconnects at once, and a failed immediate
attempt backs off as before.

A single frame that takes longer than the two windows to arrive after
foreground is still torn down. That needs smaller daemon-to-client frames and
is documented as a known limit.

* fix(client): count only fresh evidence in the foreground liveness cycle

Two gaps in the foreground cycle let stale evidence decide a fresh check.

A latency measurement outstanding at foreground is shared by the check. If a
frame had arrived during that measurement before the app was suspended, the
check read that old activity as "alive" and went back to the normal cadence
without running its windows. The check now clears the shared probe's activity
flag when it begins, so only frames that arrive from then on count.

If the app was suspended again inside the second window, the next resume
either found the queued expiry already fired (teardown before AppState) or
deduped onto the old probe and let the expiry fire right after (teardown with
no fresh window). A foreground window whose timer fires well past its deadline
on the wall clock spanned a suspension; it is now discarded together with any
activity it saw and the misses before it, and the cycle starts over. The wall
clock is used because the monotonic clock may not advance while the OS has the
process suspended.

* fix(client): keep latency measurements alive when foreground replaces a heartbeat

A latency measurement that found a heartbeat ping outstanding joins that
probe. The foreground check used to fail the probe outright to start its
fresh window, which rejected the measurement before its own deadline on a
healthy socket; the diagnostics collector treats that as a failed
collection. The superseded probe is now detached without settling and
takes the outcome of the fresh window, so the heartbeat tick and any
measurement waiting on it see the next pong or the window's timeout
instead of a spurious error.

* fix(client): let latency measurements wait for the next pong instead of a probe

A measurement that joined an outstanding heartbeat probe took that
probe's fate. The foreground check replaces such a probe, so the
measurement failed early: first with the supersede error, then, after
the hand-off to the fresh window, with that window's five-second timeout
even when the caller had asked for a longer deadline and the pong was
about to arrive.

Measurements now register as pong waiters. A waiter settles on the next
pong, on a connection failure (close, transport dispose, ping send
failure) or on its own deadline, and no longer cares which probe put the
ping on the wire. The foreground check goes back to dropping the
straddling heartbeat probe outright, since the only thing waiting on a
probe's promise is the heartbeat tick.

* fix(client): report the joined ping's round trip from a latency measurement

A measurement that joins an in-flight heartbeat ping used to start its
clock at the join, so it reported only the remaining wait for the pong.
The clock now starts at the send of the ping the measurement waits on,
which matches what the heartbeat records for the same pong.

Paseo mobile app

Paseo is an open source agentic development environment for desktop, mobile, web, and CLI. Open the desktop app and work: agents, editor, terminals, diffs, pull requests, and a browser in one window. Run many agents at once, each in its own worktree, on one machine or several. The mobile app is the full app, native on iOS and Android.

  • Parallel agents: Run many agents at once, each in its own worktree.
  • Built-in orchestration: Agents in Paseo can create worktrees, launch other agents, and talk to them, across providers.
  • Complete development workflow: Edit files, review diffs, open pull requests, and run terminals, in split panes you arrange how you want.
  • Self-hosted: Agents run on your machine with your full dev environment. Use your tools, your configs, and your skills.
  • Multi-provider: Claude Code, Codex, Copilot, OpenCode, Pi, Antigravity, and Muse Code through the same interface. Pick the right model for each job.
  • Voice control: Dictate tasks or talk through problems in voice mode. Hands-free when you need it.
  • Cross-device: iOS, Android, desktop, web, and CLI. Start work at your desk, check in from your phone, script it from the terminal.
  • Privacy-first: Paseo doesn't have any telemetry, tracking, or forced log-ins.

Run parallel tasks in Paseo: start agents in separate worktrees, review their diffs, run each app, and check it in the built-in browser.

Plugins

Plugins run on the daemon and show up in every client you connect, with the same UI on desktop, web, iOS, and Android. Write a plugin once and it is on your phone.

  • UI: screens, sidebar items, workspace panels, Command Center items, slash commands, composer pills, attachment sources, timeline items, themes.
  • Agent lifecycle: change configuration, environment, and MCP servers, answer permissions, follow up when a turn ends.
  • Providers: add a coding agent as a provider.

Install from the registry with paseo plugin add owner/slug, or from Git or a local directory.

Browse plugins · Plugin docs

Plugins run with access to your daemon machine and inside connected clients; install only code you trust.

Getting Started

Paseo runs a local server called the daemon that manages your coding agents. Clients like the desktop app, mobile app, web app, and CLI connect to it.

Prerequisites

You need at least one agent CLI installed and configured with your credentials:

Download it from paseo.sh/download or the GitHub releases page. Open the app and the daemon starts automatically. Nothing else to install.

To connect from your phone, open Settings → your host → Pair Device.

Server

For a server, a VM, or any machine without the desktop app. Install the CLI and start the daemon:

npm install -g @getpaseo/cli
paseo

Paseo starts, then asks whether to enable the end-to-end encrypted relay for device pairing. If you decline, connect directly over TCP, Tailscale, or another VPN. The desktop, mobile, and web apps connect to this daemon like any other host.

For full setup and configuration, see:

Docker

Run the Paseo daemon and self-hosted web UI in Docker:

docker run -d --name paseo \
  -p 6767:6767 \
  -e PASEO_PASSWORD=change-me \
  -v "$PWD/paseo-home:/home/paseo" \
  -v "$PWD:/workspace" \
  ghcr.io/getpaseo/paseo:latest

Open http://localhost:6767 after it starts. Extend the base image with the agent CLIs you use, then provide credentials through environment variables or the persistent /home/paseo volume. See the Docker documentation for full setup details.

CLI

Everything you can do in the app, you can do from the terminal.

paseo run --provider claude/opus-4.6 "implement user authentication"
paseo run --provider codex/gpt-5.5 --worktree feature-x "implement feature X"

paseo ls                           # list running agents
paseo attach abc123                # stream live output
paseo send abc123 "also add tests" # follow-up task

# run on a remote daemon; --cwd is a path on that host
paseo run --host workstation.local:6767 --cwd /workspace "run the full test suite"

See the full CLI reference for more.

TypeScript SDK

Build issue integrations, dashboards, and orchestration services with @getpaseo/client:

import { createPaseoClient } from "@getpaseo/client";

const client = createPaseoClient({ url: "ws://127.0.0.1:6767/ws" });
await client.connect();

const agent = await client.agents.create({
  config: { provider: "codex/gpt-5.5" },
  cwd: "/Users/me/dev/storefront",
  prompt: "Review the current diff and name the riskiest change.",
});

const result = await agent.waitForFinish();
console.log(result.lastMessage);

await client.close();

See the SDK quickstart, recipes, and API reference.

Skills

Skills teach your agent to use Paseo to orchestrate other agents.

npx skills add getpaseo/paseo

Then use them in any agent conversation:

  • /paseo-handoff — hand off work between agents. I use this to plan with Claude and then handoff to Codex to implement.
  • /paseo-advisor — spin up a single agent as an advisor for a second opinion, without delegating the work itself.
  • /paseo-committee — form a committee of two contrasting agents to step back, do root cause analysis, and produce a plan.

Development

Quick monorepo package map:

  • packages/server: Paseo daemon (agent process orchestration, WebSocket API, MCP server)
  • packages/app: Expo client (iOS, Android, web)
  • packages/cli: paseo CLI for daemon and agent workflows
  • packages/desktop: Electron desktop app
  • packages/relay: Relay transport and encryption used by the daemon and clients
  • packages/website: Marketing site and documentation (paseo.sh)

Common commands:

# run all local dev services
npm run dev

# run individual surfaces
npm run dev:server
npm run dev:app
npm run dev:desktop
npm run dev:website

# build the server stack
npm run build:server

# repo-wide checks
