Mohamed BoudraandGitHub 26b2f25050 refactor(server): decompose session.ts into per-domain subsystems (#1646)
* refactor(server): move checkout write handlers into CheckoutSession

The checkout read side moved into session/checkout/checkout-session.ts in
#1644; the 17 inline write/PR/stash handlers stayed on the Session god-object.
This carves them into the same subsystem behind an expanded CheckoutSessionHost,
so dispatchCheckoutMessage becomes pure delegation and session.ts drops ~800
lines.

Moved into CheckoutSession (verbatim, only this.X -> this.host.X rewiring):
switch/rename branch, commit, merge, merge-from-base, pull, push, PR
create/merge, github auto-merge/check-details, PR status/timeline, github
search, stash save/pop/list, plus resolveCurrentPullRequest and the
PR-timeline helpers.

CheckoutSessionHost gains the Session-owned, non-checkout collaborators these
handlers orchestrate (notifyGitMutation, emitWorkspaceUpdateForCwd,
handleWorkspaceGitBranchSnapshot, renameCurrentBranch, checkoutExistingBranch,
and the LLM commit/PR-text generators); paseoHome/worktreesRoot join the
options bag. GitMutationRefreshReason moves to utils/checkout-git.ts so both
the shell and the subsystem share one canonical type.

session.test.ts checkout tests now drive the handlers through the public
handleMessage boundary instead of reaching into private methods; new mock-free
fake-host tests cover the moved handlers directly in checkout-session.test.ts.

Behavior-preserving: full session.test.ts + checkout-session.test.ts green,
typecheck/lint/format clean.

* refactor(server): extract chat/schedule/loop handlers into ChatScheduleLoopSession

Move the 7 chat/*, 9 schedule/*, and 5 loop/* request handlers, the three
rpc-error emitters (kept separate), and toScheduleSummary out of the Session
god-object into session/chat/chat-schedule-loop-session.ts, mirroring the shipped
CheckoutSession/VoiceSession deep-module-with-narrow-Host pattern. The least-coupled
remaining domain: stateless request/response over chatService/scheduleService/
loopService, reaching the shell only through a narrow ChatScheduleLoopSessionHost
(emit + agent-roster reads + the mention-fanout send). session.ts drops ~590 lines.

The two dispatch switches collapse into one: schedule/* was previously reached only
via the chat dispatcher's default fall-through arm — now all 21 types are explicit
delegation cases, removing that fragility.

Behavior-preserving: a new routing test drives the real Session.handleMessage for all
21 types (guards against a silently-dropped case), green before and after the move; a
collocated subsystem test covers the mention-fanout send seam, the fanout-limit error
code, the self->agent target remap, and the toScheduleSummary runs-stripping.

* refactor(server): extract provider catalog handlers into ProviderCatalogSession

Move the 8 provider-catalog handlers (model/mode/feature listing, providers
snapshot pull/refresh, diagnostic, usage) plus emitProviderDisabledResponse,
getProviderSnapshotEntryForRead, buildDraftAgentSessionConfig, the two mode-icon
downgrade helpers, and the providers_snapshot_update PUSH wiring out of session.ts
into session/provider/provider-catalog-session.ts behind a narrow
ProviderCatalogSessionHost seam — the same deep-module pattern as ChatScheduleLoopSession,
CheckoutSession, and VoiceSession.

The PUSH (start) and every PULL gate provider visibility and downgrade mode icons
through the SAME injected predicates (isProviderVisibleToClient + supportsCustomModeIcons),
both reading appVersion/clientCapabilities live — the COMPAT invariant the shell could
only enforce by code proximity before. dispatchProviderMessage collapses to delegation;
start()/dispose() wire into subscribeToOptionalManagers/cleanup at the same ordinal.

session.ts drops ~372 lines. Behavior-preservation gate (provider routing through the
real Session.handleMessage) green before and after; full session.test.ts 115/115; new
collocated subsystem test covers the PUSH/PULL parity seam, the disabled-provider path,
and the usage/feature error envelopes.

* refactor(server): extract workspace file-access handlers into WorkspaceFilesSession

Move the file-explorer, file-upload, file-transfer-frame, project-icon and
file-download-token handlers out of session.ts into
session/files/workspace-files-session.ts behind a narrow WorkspaceFilesSessionHost
seam (emit/emitBinary/hasBinaryChannel), matching the deep-module-with-Host shape
used by CheckoutSession/ChatScheduleLoopSession/ProviderCatalogSession.

The new module owns the FileUploadStore and is injected the daemon's
DownloadTokenStore; the shell's dispatch cases and the file_transfer binary route
collapse to delegation. The five handlers touch no workspace-git observer,
registry or subscription state, so this is a clean self-contained slice of the
workspace domain. session.ts drops 240 lines (7316 -> 7076).

Behavior-preservation tests (file explorer list/read/binary, download token
success + empty-cwd, project icon, upload round-trip) added to session.test.ts and
run green against the pre- and post-refactor Session; a collocated
workspace-files-session.test.ts exercises the module via a fake host with real
upload/download stores (no module mocks).

* refactor(server): extract agent-config setters into AgentConfigSession

Move the four agent-config setters (set_agent_mode/model/feature/thinking)
out of the session god-object into session/agent-config/, collapsing their
four near-identical try/log/emit envelopes into one applyConfigChange helper
behind a narrow { emit } host plus an AgentConfigOperations port.

Behavior-preserving: the dispatch cases delegate unchanged, setAgentModeCommand
still routes the mode path, and model/feature still emit no notice. Adds the
previously-absent failure-envelope coverage: 8 gate tests in session.test.ts
(success + forced failure per setter, asserting the *_response envelope and the
activity_log-before-response ordering) green before and after the carve, plus a
collocated agent-config-session.test.ts (typed fake operations + fake host, no
module mocks). session.ts drops ~173 lines.

* refactor(server): extract project-config handlers into ProjectConfigSession

Move read/write_project_config handlers, their failure emitters, and the
root-resolution helpers (resolveKnownProjectRootForConfig, canonicalizeConfigRoot,
stripTrailingPathSeparators) out of session.ts into session/project-config/, behind
a narrow { emit } host plus a projectRegistry port — matching the established
session/<domain>/ pattern. Also corrects a misfiling: project-config was dispatched
inside dispatchAgentConfigMessage despite being its own domain.

session.ts drops 155 lines (6903 -> 6748). The handleMessage-driven gate in
session.test.ts (project config RPC authorization) is green before and after; new
collocated project-config-session.test.ts covers the subsystem with a fake host and
fake registry over a real filesystem (no module mocks).

* refactor(server): extract daemon status/pairing handlers into DaemonSession

Move the two daemon.* RPC handlers (daemon.get_status, daemon.get_pairing_offer)
out of session.ts into session/daemon/daemon-session.ts behind a narrow
{ emit } host + injected reads (paseoHome, serverId, daemonVersion,
daemonRuntimeConfig, listProviderAvailability). These were misfiled inside
dispatchAgentConfigMessage despite being daemon- not agent-scoped; the slice
also removes the now-dead serverId/daemonVersion/daemonRuntimeConfig fields and
the getPidLockInfo/generateLocalPairingOffer imports from the god-file, and
collapses the inline daemonRuntimeConfig type into a named DaemonRuntimeConfig.

The daemon-config get/set handlers stay inline: daemonConfigStore is a
listener-bearing, cross-domain hub (read by structured-generation,
websocket-server, bootstrap, archive-if-safe), so moving it would double-own it.

session.ts: 6748 -> 6662 lines. Gate: new session.test.ts daemon round-trips
(status success + listing-rejects fallback, pairing relay-disabled) pass before
and after; new collocated daemon-session.test.ts (fake host + injected reads
over a real temp dir, no module mocks) 4/4. typecheck/lint/format clean.

Note

I'm a solo maintainer and don't always keep up with GitHub Issues daily. If something is urgent or blocking you, Discord is the fastest place to reach me.


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, scan the QR code shown in Settings.

CLI / headless

Install the CLI and start Paseo:

npm install -g @getpaseo/cli
paseo

This shows a QR code in the terminal. Connect from any client. This path is useful for servers and remote machines.

For full setup and configuration, see:

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 package for remote connectivity
  • 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
npm run typecheck
