47c18a9213 Fork an agent session mid-run from the in-flight turn footer (#2638)
* feat(app): fork an agent session mid-run from the tab menu

Forking already existed, but only on the footer of a *completed*
assistant turn. While an agent is running, the in-flight turn renders
RunningTurnFooter with no fork menu, so exploring another path meant
scrolling back to hunt for an older turn's footer — or waiting for the
run to finish.

Add two entries to the agent tab context menu ("Fork chat in a new tab",
"Fork chat in a new workspace"), reachable regardless of run state. They
omit the fork boundary, and selectForkContextRows projects the whole
timeline when no boundary is given, so a mid-run fork carries everything
up to now — including the partially streamed in-flight turn.

Fork logic moves out of agent-stream/view.tsx into a shared useForkAgent
hook so the turn footer and the tab menu share one code path; the
per-turn behavior is unchanged (it still pins a boundary to its turn).

No server, protocol, or capability changes — this reuses the existing
agent.fork_context RPC and agentForkContext host feature. The daemon
handler is already a pure in-memory timeline read, so it was safe
mid-turn before this change.

* fix(app): resolve missing agent records before failing a fork

handleForkAgent read the agent record from the session store and gave up
if it was absent from both agents and agentDetails. A persisted agent tab
can outlive its record — restored on startup before hydration — so both
fork entries failed with a generic toast even though the agent exists on
the daemon and is perfectly forkable.

Fall back to client.fetchAgent and store the result before failing,
mirroring the resolution path agent-panel.tsx already uses. Only report
forkFailed when the agent genuinely cannot be resolved; a disconnected
host now says so instead.

The resolution logic lands in resolveForkAgentSource with injected
dependencies, since workspace-screen.tsx has no handler-level test
harness and a sibling testable module is the pattern in this directory.

storeFetchedAgentDetail moves out of panels/agent-panel.tsx into
utils/agent-detail-store.ts so the workspace screen doesn't import a
panel module — and into its own file rather than agent-directory-sync.ts,
which would close an import cycle through legacy-daemon-workspaces.

* feat(app): fork from the in-flight turn instead of the tab menu

Move the mid-run fork affordance to where the fork button already lives:
the assistant turn footer, beside the progress loader.

RunningTurnFooter previously showed only a spinner and elapsed timer, so
the fork button vanished for the whole duration of a run. It now renders
AssistantForkMenu alongside them, reachable the moment a run starts.

The in-flight fork passes no boundary, so selectForkContextRows projects
the whole timeline and the fork captures the response being streamed. A
fork button sitting next to a live response that silently dropped that
response would be worse than no button. Completed turns still pin their
own boundary, enforced by a separate handler type that keeps boundary
required.

layout.ts is untouched — the affordance is added to the running footer
component rather than by lifting the footer suppression, so no copy or
duration affordance leaks onto an incomplete turn.

Reverts the workspace tab context menu approach, along with the agent
resolution helper and store-writer extraction that existed only to serve
it. The footer path already holds the agent record.

* test(app): cover the in-flight turn fork with a Playwright spec

Extends the existing assistant fork menu spec rather than adding a
sibling file, so the completed-turn and in-flight cases sit side by side.

The new test pins the behavior that defines the feature: the in-flight
fork omits the boundary fields entirely, while the completed-turn fork
sends one. Both assertions read the actual agent.fork_context frames off
the WebSocket, using the read-only page.on("websocket") idiom from
helpers/timeline-delivery.ts so the observer cannot perturb the flow it
measures. Note the request omits the fields rather than nulling them —
daemon-client spreads them conditionally — so absence is what's asserted
there, and null only on the response.

Also asserts the fork trigger is scoped inside turn-working-indicator,
that no copy or duration affordance leaks onto the incomplete turn, that
the attachment carries the streamed text, and that the source agent keeps
streaming afterwards.

* test(app): cover the in-flight fork call site, gate, and teardown

Three behaviors this PR introduced had no coverage below the Playwright
spec. A copy-paste of resolveAssistantTurnForkBoundary into
handleForkInFlightTurn would have left every unit test green.

view-fork-in-flight.test.tsx mounts the real AgentStreamView with the
render strategy stubbed to the live-auxiliary slot, so handleForkInFlightTurn,
useStableEvent and the readOnly expression all stay real. It asserts the
fork request has no boundary KEY — matching the wire contract, where the
field is absent rather than null — for both targets, and that the read-only
gate withholds the trigger, with positive controls either side so an empty
tree cannot pass for a working gate.

turn-footer.test.tsx covers the race this PR created: the fork menu now
mounts only while a run is in flight, so a fork can be pending when the
subtree is torn down. The behavior is benign — React 18 makes the orphaned
setState a no-op — so the test asserts the observable outcome and leaves a
tripwire for unhandled rejections, since AssistantForkMenu's finally has no
catch.

Each test was verified by mutation: adding boundary: undefined, dropping the
readOnly gate, and keeping the running subtree alive each fail the matching
test.

Scoped to what this PR changed. The relocated hook's error paths, draft
setup construction, and attachment metadata predate it and stay untested
here.

* test(app): replace mocked fork coverage with Playwright

Paseo mobile app

Run agents in parallel on your own machines. Ship from your phone or your desk.

  • 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, and Pi 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.

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.

CLI / headless

Install the CLI and start Paseo:

npm install -g @getpaseo/cli
paseo

Paseo starts locally, 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. This path is useful for servers and remote machines.

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-5.4 --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
paseo --host workstation.local:6767 run "run the full test suite"

See the full CLI reference for more.

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-loop — loop an agent against clear acceptance criteria (aka Ralph loops), optionally with a verifier.
  • /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)
