From 6b49e6f45f6733a130b35b7cdcac49675ff9ecbd Mon Sep 17 00:00:00 2001 From: ReconGrunt Date: Mon, 8 Jun 2026 02:34:31 -0700 Subject: [PATCH] feat(server): multi-instance support + Claude Remote Control launch Run multiple T3 server instances on one PC (Cursor-style), and launch the official Claude Code Remote Control feature from T3. Multi-instance: - InstanceRegistry: per-instance JSON lock files under a shared ~/.t3/instances dir with dead-pid pruning (announce/withdraw/list). - 't3 instances' command; 't3 start --instance ' derives an isolated per-instance baseDir (explicit --base-dir/T3CODE_HOME still wins). - server.ts announces on startup / withdraws on shutdown (failure-isolated). Claude Remote Control (CLI-only; not exposed by the Agent SDK T3 normally uses to drive Claude): - ClaudeRemoteControlLauncher spawns the real claude binary in RC mode ('claude remote-control' / '--remote-control'), reusing makeClaudeEnvironment for HOME/account selection. - 't3 remote-control' / 'rc' command; the session is then driven from the Claude iOS/web app via Anthropic's relay (no custom relay built). Docs: multi-instance.md, remote-control.md, web-surfaces-spec.md + provider/runtime/remote-access updates. Session record under AGENT_SWARM.md, swarm/, SPRINT_1_DELIVERABLE.md. Verified on Windows: server package typecheck green; 14/14 new unit tests pass. Desktop multi-window and in-app PTY launch are specced for a follow-up.

(HEAD_DEV decision, user-confirmed: "Launch CLI in RC mode".) +- Reuse for the launcher: `apps/server/src/provider/Drivers/ClaudeHome.ts` (`makeClaudeEnvironment`, + HOME/account resolution), `ProviderInstanceEnvironment` env merge, `@t3tools/shared/cliArgs` + `parseCliArgs`.

ATLAS has documented the target behavior in `multi-instance.md`. + +2. **RC in-app trigger RPC:** The web surfaces spec calls for a server RPC that the RC Launch + button invokes. BEACON's contract (C3) covers the CLI path and terminal Manager launch, but + the exact RPC shape (WebSocket message type, payload) is not yet contracted. HELM and BEACON + should agree on this before ATLAS finalizes the spec's "data source" section. + +3. **RC pairing-confirmed detection:** The "Paired" state in the RC action mockup depends on + detecting a pairing-confirmed string in the `claude` process stdout. The exact string varies + by `claude` CLI version. Should T3 parse this heuristically (fragile) or wait for a future + claude CLI API to expose pairing state? Recommendation: ship with terminal-output-only + (user reads the terminal panel), and add auto-detection later when the string is stable. + +4. **`t3 instances` RPC vs CLI-only:** The instance switcher UI reads the registry via a server + RPC. HELM should confirm that the registry-read logic is exposed over WebSocket (not only + as a CLI command) so the UI can consume it. If the server always has access to the shared + lock file directory, this is straightforward — flagging for explicit sign-off. + +5. **Instance switcher in web vs desktop:** The "Open new window" action in the instance switcher + requires Electron multi-window support (deferred per open question 1). In the web client, + "Open" can open a new browser tab. Should the spec show different behavior per client type, + or should "Open" be hidden in web for Sprint 1? Recommendation: hide in web until multi-window + desktop lands; then revisit for consistency. + +6. **BEACON agents log:** No `swarm/BEACON.md` or `swarm/HELM.md` existed when ATLAS ran. + ATLAS proceeded on contracts as instructed. If HELM or BEACON produced conflicting design + decisions in their own sessions, HEAD_DEV should reconcile before integration. + +--- + +## Deferred to Next Sprint + +| Item | Reason | Owner | +| --- | --- | --- | +| Desktop multi-window (Electron `requestSingleInstanceLock` removal + per-window port) | Risk assessment needed; non-trivial reversal path | HELM + HEAD_DEV | +| TypeScript component code for instance switcher | Spec-only this sprint; no typecheck toolchain available | ATLAS → implementation sprint | +| TypeScript component code for RC action in provider card | Spec-only this sprint | ATLAS → implementation sprint | +| RC pairing-confirmed auto-detection (terminal output parsing) | Fragile until CLI string is stable | BEACON → future sprint | +| `t3 instances` RPC shape formal contract | Needs HELM sign-off | HELM → Sprint 2 contract | +| RC WebSocket RPC shape | Needs HELM + BEACON alignment | HELM + BEACON → Sprint 2 | +| `docs/README.md` and `README.md` links to new guides | Low priority housekeeping | HEAD_DEV or ATLAS Sprint 2 | + +--- + +## Notes + +- All ATLAS file changes are docs and specs only.

No existing content was removed. +- The UI design spec references exact C1 and C3 contract shapes from `AGENT_SWARM.md`. + If HELM changes the C1 shape before implementation, the spec should be updated to match. +- HEAD_DEV finalizes the Status column for HELM and BEACON rows after reviewing their logs + and integration output. + +--- + +## HEAD_DEV Finalization + +**Integration:** `bin.ts` now imports and registers both `instancesCommand` and `remoteControlCommand` +in `makeCli`'s subcommand list. No file-domain conflicts occurred — all three agents stayed inside +their OUTPUTS blocks. Cross-domain shapes verified consistent (C1 record identical across impl, +announce, print, and docs). + +**Resolutions to the open questions:** + +1. **Desktop multi-window:** Deferred to Sprint 2 (correctly specced, not coded). HELM found the + single-instance gate lives in `DesktopCloudAuth.ts` (OAuth deep-link handling), not `ElectronApp.ts`, + and the desktop backend port is *already* dynamic (`resolveDesktopBackendPort` scans from 3773). + Each desktop window already runs `server.ts`, so it already announces into the shared registry — + discovery works today; only the single-window *gate* needs lifting. This is the right risk call. +2. **RC in-app trigger RPC + 3. pairing detection + in-app PTY launch:** Deferred together. The CLI + path (`t3 remote-control` / `rc`) is the shippable Sprint-1 surface. The in-app button needs a + terminal "run argv+env in PTY" entry point that this clone's `terminal/Services/Manager.ts` does not + yet expose. Sprint 2: add that entry point, then the WebSocket RPC + the provider-card action. + Ship RC pairing as terminal-output-only first (no fragile stdout parsing). +4. **`t3 instances` over RPC:** The registry reads a shared on-disk dir, so any server process can list + it. Exposing it over WebSocket for the UI is a thin Sprint-2 addition; the CLI command works now. +6. **Agent-log race:** Both `swarm/HELM.md` and `swarm/BEACON.md` exist; no conflicting design + decisions — HELM's C1 shape and BEACON's CLI match what ATLAS documented. Reconciled. + +**Verification results (vp toolchain installed; Node 24.16.0 via `vp env`):** + +- [x] `vp run --filter t3 typecheck` (tsgo) on `apps/server` — **green** after fixes below. +- [x] Effect API spellings confirmed against the installed version (`Schema.fromJsonString`, + `Effect.ignore({ log: true })`, `FileSystem.remove(..., { force: true })` all valid; the only + real fixes were `Order.String` casing and providing `FileSystem`/`Path` to `announce`). +- [x] `Crypto.Crypto` resolves in `makeServerLayer`'s context — `server.ts` typechecks clean. +- [x] `ChildProcessSpawner` + `Path` resolve from `bin.ts`'s `CliRuntimeLayer` — RC command typechecks clean. +- [x] `vp test run` for `InstanceRegistry.test.ts` and `ClaudeRemoteControlLauncher.test.ts` — **14/14 pass.** +- [ ] Manual smoke (needs a real Claude Pro/Max login): `t3 start --instance work` + + `t3 start --instance personal` → two isolated instances on distinct ports; `t3 instances` lists + both; `t3 remote-control` launches `claude` in RC mode and pairs with the phone. + +**Fixes applied during verification (all in new/owned files):** `cli/instances.ts` used a +non-existent `InstanceRegistry.layer` static (now imports the `layer` export); `InstanceRegistry.ts` +used `Order.string` (→ `Order.String`) and leaked `FileSystem | Path` from `announce` (now provided); +test type-widening + one lint directive; and the RC launcher test's HOME assertion was made +platform-agnostic via `path.resolve`. Net: typecheck green, 14/14 unit tests pass. + +**Note:** two failures in the pre-existing `provider/Layers/ProviderInstanceRegistryLive.test.ts` are +not part of this work — they hardcode POSIX paths (`/home/julius/.codex`) and fail only on Windows +(`path.resolve` → `C:\home\julius\.codex`). They pass on the Linux CI and are unrelated to these changes. diff --git a/apps/server/src/bin.ts b/apps/server/src/bin.ts index 04d5bdfadaa..193e67dd064 100644 --- a/apps/server/src/bin.ts +++ b/apps/server/src/bin.ts @@ -11,7 +11,9 @@ import { authCommand } from "./cli/auth.ts"; import { cloudCommand } from "./cli/cloud.ts"; import { hasCloudPublicConfig } from "./cloud/publicConfig.ts"; import { sharedServerCommandFlags } from "./cli/config.ts"; +import { instancesCommand } from "./cli/instances.ts"; import { projectCommand } from "./cli/project.ts"; +import { remoteControlCommand } from "./cli/remoteControl.ts"; import { runServerCommand, serveCommand, startCommand } from "./cli/server.ts"; const CliRuntimeLayer = Layer.mergeAll(NodeServices.layer, NetService.layer); @@ -47,6 +49,8 @@ export const makeCli = ({ cloudEnabled = hasCloudPublicConfig } = {}) => serveCommand, authCommand, projectCommand, + instancesCommand, + remoteControlCommand, cloudEnabled ? cloudCommand : cloudUnavailableCommand, ]), ); diff --git a/apps/server/src/cli/config.ts b/apps/server/src/cli/config.ts index 7182854e18c..79dc4375721 100644 --- a/apps/server/src/cli/config.ts +++ b/apps/server/src/cli/config.ts @@ -42,6 +42,15 @@ export const baseDirFlag = Flag.string("base-dir").pipe( Flag.withDescription("Base directory path (equivalent to T3CODE_HOME)."), Flag.optional, ); +// Multi-instance convenience (contract C2): a friendly name that maps to a deterministic +// per-instance base directory under the well-known root, so isolated instances need no manual +// `--base-dir`.

Port `3773` is claimed by the first instance that starts; +subsequent instances bind `3774`, `3775`, and so on. + +In desktop mode the default behavior pins port `3773`. The multi-window extension described at +the end of this document changes that behavior. + +--- + +## The `--instance` Convenience Flag + +Running two default-`baseDir` instances on the same machine would cause them to share the same +SQLite database and settings — they would collide. + +The `--instance <name>` flag assigns a friendly name that maps to a deterministic, isolated +base directory automatically: + +```text +<defaultBaseRoot>/instances-data/<name> +``` + +Examples: + +```bash +t3 start --instance work +t3 start --instance personal +t3 start --instance experiment +``` + +Each name produces a completely separate data directory. The name can be any identifier that is +safe for a directory component. No two instances share data as long as their names differ. + +The `--instance` flag is a shorthand. Passing `--base-dir` with an explicit path is equivalent +and has identical isolation properties. + +--- + +## The Instance Registry + +### Purpose + +The registry answers the question: *which instances are currently running on this machine?* + +Without a registry, there is no way to discover a running instance's port or PID — you would +have to scan ports or parse process lists. The registry solves discovery in a structured, low- +overhead way. + +### Mechanism: JSON Lock Files + +A running instance announces itself by writing a JSON lock file to a shared directory: + +```text +<defaultBaseRoot>/instances/<instanceId>.json +``` + +`instanceId` is a stable identifier for the instance (derived from its `baseDir`). + +The lock file is written on server start and deleted on clean shutdown. On unclean shutdown the +file is left behind and treated as stale (see Stale Entry Pruning below). + +### Lock File Shape + +```jsonc +{ + "instanceId": "string", // stable identifier derived from baseDir + "name": "string | null", // value of --instance flag, or null + "pid": 1234, // OS process ID of the server + "port": 51234, // bound TCP port + "host": "127.0.0.1", // bind host + "baseDir": "/abs/path", // absolute path to this instance's base directory + "cwd": "/abs/path", // working directory the server was started from + "startedAt": "ISO", // ISO 8601 timestamp + "schemaVersion": 1 // integer version for forward compatibility +} +``` + +This is the canonical shape defined in Contract C1. + +### Stale Entry Pruning + +When `t3 instances` or any registry reader enumerates the lock files, it checks whether the +recorded `pid` is still alive. If the process is dead the entry is treated as stale, removed from +the result set, and optionally deleted from disk. Callers must never assume that a lock file +corresponds to a live process without checking `pid`. + +--- + +## The `t3 instances` Command + +`t3 instances` lists all live instances discovered in the registry. + +Example output: + +```text +NAME INSTANCE ID PORT PID BASE DIR +work work-a3f2 3773 84123 ~/.t3/instances-data/work +personal personal-b1c9 3774 84456 ~/.t3/instances-data/personal +(default) default-cc1a 3775 85001 ~/.t3 +``` + +Each row corresponds to one live lock file entry. Stale entries are pruned before the table is +printed. If no live instances are found the command prints a message indicating the registry is +empty. + +The command does not require a running server — it reads the shared lock file directory directly. + +--- + +## Connecting to a Named Instance + +Once instances are running, `t3 start --instance <name>` in a second terminal reuses the same +base directory and port as the named instance. This is useful for scripted reconnects or for +opening a second client window against an existing instance. + +```bash +# Start the instance +t3 start --instance work + +# Later, connect a second client to the same instance +t3 start --instance work +``` + +The second invocation finds port `3773` (or whichever port `work` bound) already occupied, so +`findAvailablePort` skips it and the new server lands on the next free port — but both instances +share the same `baseDir` (`~/.t3/instances-data/work`), so they share state. For the common +use case of a single client per instance this is transparent. + +--- + +## Desktop Multi-Window + +The desktop app currently uses `requestSingleInstanceLock` to enforce a single process and pins +port `3773`. True multi-window support requires lifting those constraints. + +**Current state:** Single-instance lock is in `apps/desktop/src/electron/ElectronApp.ts`. +Removing it and adding per-window port assignment are the two changes needed. + +**Target behavior:** + +- Each new desktop window calls `findAvailablePort` (same as web mode today). +- Each window writes its own registry entry so `t3 instances` lists all open windows. +- The `--instance <name>` flag is available from the desktop app's "New window" flow to pre-select + an isolated base directory. + +**Sprint 1 status:** Multi-window desktop is specified here. Implementation is deferred to a +follow-up pass. The single-instance enforcement lives in +`apps/desktop/src/app/DesktopCloudAuth.ts` and is entangled with OAuth deep-link handling; +removing it safely requires a typecheck pass.

I will REUSE this verbatim — no + reimplementation of HOME logic (per IMPLEMENT.1). + +2. **`ClaudeSettings` shape** (contracts/src/settings.ts): `enabled`, `binaryPath` (default `"claude"`), + `homePath` (default `""`), `customModels`, `launchArgs` (default `""`). The launcher input only needs + `binaryPath` + `homePath` (+ optional `launchArgs`); I'll type the input as a `Pick`-style structural + subset so a full `ClaudeSettings` satisfies it. + +3. **Canonical spawn mechanism = `ChildProcessSpawner` + `ChildProcess.make(command, args, options)`.** + `providerMaintenanceRunner.ts` spawns `claude update` this exact way; `externalLauncher.ts` shows the + `spawner.spawn(ChildProcess.make(...))` + `Effect.scoped` + `mapError` pattern and the canonical TEST + style (`Layer.mock(ChildProcessSpawner.ChildProcessSpawner, { spawn })` capturing `spawnedCommand`, + asserting `.command` / `.args` / `.options`). `CommandOptions` supports `stdin/stdout/stderr: "inherit"`, + `cwd`, `env` + `extendEnv`. Handle exposes `.exitCode: Effect<ExitCode, PlatformError>` and `.kill()`. + For RC we want **inherited stdio** so pairing/registration output is visible (IMPLEMENT.1). + +4. **CLI command structure** (auth.ts / project.ts / server.ts): `Command.make(name, flags).pipe(` + `Command.withDescription, Command.withHandler)`. Flags via `Flag.string/boolean/choice` + `Flag.optional` + / `Flag.withDefault` / `Flag.withAlias`; positional via `Argument.string(...).pipe(Argument.optional)`. + Handlers `yield* GlobalFlag.LogLevel` and run an Effect. The root `t3` command (bin.ts `makeCli`) provides + `CliRuntimeLayer = Layer.mergeAll(NodeServices.layer, NetService.layer)` — `NodeServices.layer` supplies + **both `ChildProcessSpawner` and `Path.Path`** to every subcommand handler. So my handler can `yield*` + the spawner/path directly; no extra layer wiring needed (and I must NOT touch bin.ts — C4). + +5. **Error class style** = `Schema.TaggedErrorClass<T>()("Name", { fields })` with `override get message()`. + provider/Errors.ts is the template. I'll mirror it in a new `remoteControl/Errors.ts`. + +6. **`parseCliArgs`** (shared/cliArgs.ts) is what ClaudeAdapter uses to split `launchArgs`. For RC passthrough + I will accept already-tokenized passthrough args from the CLI and NOT re-parse the official RC flags; the + `--name <title>` is handled explicitly per spec. + +7. **In-app terminal launch path is NOT fully wireable this session.** `apps/server/src/terminal/` contains + ONLY `Services/Manager.ts` (the `TerminalManagerShape` *interface* + `PTY.ts` import) in this clone — there + is NO `terminal/Layers/NodePTY.ts` and no concrete live layer present (grep/glob confirm).

Findings verified against source: + +1. **Default base root is `~/.t3`.** `resolveBaseDir(undefined)` returns `join(homedir(), ".t3")` + (os-jank.ts:98-104). Explicit `--base-dir`/`T3CODE_HOME` override it. This is the well-known + root. The shared registry dir MUST be computed from `resolveBaseDir(undefined)` directly + (NOT from any instance's own baseDir), so every instance — including `--instance work` whose + baseDir is `~/.t3/instances-data/work` — shares ONE registry dir at `~/.t3/instances/`. Using + `dirname(baseDir)` would NOT be stable (default baseDir's dirname is `~`, an instance's is + `~/.t3/instances-data`). Decision: registry root = `<defaultBaseRoot>/instances` where + `defaultBaseRoot = resolveBaseDir(undefined)`. Matches contract C1 exactly. + +2. **`ServerConfigShape` is asserted by strict `toEqual` in 7 cli/config.test.ts cases AND by + `satisfies ServerConfigShape` object literals in bin.test.ts:58 and server.test.ts:374.** + Therefore any new field on `ServerConfigShape` MUST be `optional` (`readonly instanceName?: string`) + so the `satisfies` literals still compile, and MUST default to `undefined` (not `null`) when absent + so vitest `toEqual` (which ignores undefined-valued keys) keeps all existing assertions green. + This is the load-bearing constraint that shapes the whole config edit. + +3. **`runServerCommand` (cli/server.ts:8) is the single call site** that resolves config and launches + `runServer` with `ServerConfig` provided. `resolveServerConfig` is the one place baseDir is derived. + So `--instance` is added to `sharedServerCommandFlags` + `CliServerFlags`, consumed inside + `resolveServerConfig` to (a) derive a deterministic per-instance baseDir when no explicit + base-dir/env, and (b) set `config.instanceName`. server.ts reads `config.instanceName` for announce. + +4. **server.ts lifecycle uses `Layer.effectDiscard(Effect.acquireRelease(acquire, release))`** + merged into `serverApplicationLayer` (runtimeStateLayer/tailscaleServeLayer are the templates; + they read `HttpServer.HttpServer.address` for the bound port). I will add an analogous + `instanceRegistryLayer` that announces on acquire (using the actually-bound port) and withdraws on + release. It MUST be failure-isolated (catch + logWarning) so registry I/O can never break startup — + important because server.test.ts integration tests exercise this path with temp baseDirs. + +5. **Persistence idiom** (serverRuntimeState.ts + atomicWrite.ts): `Schema.Struct` record, + `Schema.decodeUnknownEffect(Schema.fromJsonString(Record))`, write via `writeFileStringAtomically`, + read via `fs.exists` → `fs.readFileString` → decode `.pipe(Effect.option)`, remove via + `fs.remove(path, { force: true })`. I will mirror this exactly for the registry. + +6. **Net service** exposes `findAvailablePort(preferred)` (already used by resolveServerConfig in web + mode). No new networking needed for the registry; the port comes from the bound HttpServer address. + +7. **DESKTOP MULTI-INSTANCE IS HIGHER-RISK THAN THE AUDIT ASSUMED — SPEC, do not implement.** + - `ElectronApp.ts` is a thin Effect service wrapper around `Electron.app`; it merely *exposes* + `requestSingleInstanceLock` as a method. It does NOT call it and pins NO port. Editing it (per the + OUTPUTS MAP path) would be the wrong place and accomplish nothing. + - The actual single-instance ENFORCEMENT lives in `DesktopCloudAuth.ts:293` and is entangled with + OAuth deep-link handling (`open-url`, `second-instance` argv parsing for the cloud-auth callback). + - The "fixed port 3773" is ALREADY not fixed: `DesktopApp.ts:61 resolveDesktopBackendPort` scans from + 3773 upward across hosts and picks the first free port. So dynamic-port for desktop largely exists. + Touching this without a typecheck is LOW-confidence and could break cloud-auth pairing. Per the + OUTPUTS MAP escape hatch ("implement if low-risk, else SPEC it"), I will SPEC desktop multi-instance + precisely (DESIGN/HANDOFF) and NOT edit any desktop file. + +8. **No file-domain conflicts.** ATLAS (docs) and BEACON (remoteControl/*) are disjoint from my files. + Both pin the C1 record shape `{ instanceId, name, pid, port, host, baseDir, cwd, startedAt, + schemaVersion }`; I will match it byte-for-byte.

Editing it accomplishes nothing. The real state is: + - Single-instance ENFORCEMENT lives in `apps/desktop/src/app/DesktopCloudAuth.ts:293` + (`requestSingleInstanceLock` → quit if not primary), entangled with OAuth deep-link handling + (`open-url`, `second-instance` argv parsing that routes the cloud-auth callback to the primary). + - The "fixed port 3773" is ALREADY dynamic: `apps/desktop/src/app/DesktopApp.ts:61 + resolveDesktopBackendPort` scans upward from 3773 across hosts and picks the first free port. So the + per-instance backend-port problem is essentially already solved for desktop. + +Required changes for N desktop windows (each its own backend), in priority order: + (1) Decide the model: "multi-window, single app process" (recommended, low Electron risk) vs + "multiple app processes". Multi-window keeps ONE Electron process owning the protocol/deep-link + registration and spawns one backend per window via the existing DesktopBackendManager (which already + picks a free port). This avoids relitigating the single-instance lock. + (2) If multiple app PROCESSES are truly required: change DesktopCloudAuth.ts so a secondary instance no + longer hard-quits. Today: `if (!hasInstanceLock) quit`. New: secondary still launches its own + backend window, but FORWARDS any protocol/cloud-auth callback URL to the primary via the + `second-instance` event (the relay path already exists — it currently only reveals the primary + window). The primary must remain the sole protocol client; secondaries must NOT + `setAsDefaultProtocolClient`. This is the risky part (OAuth correctness) and needs a real typecheck + + manual pairing test → HEAD_DEV/desktop owner follow-up. + (3) Surface instance identity in the desktop window (so ATLAS's instance switcher can show which window + is which). Each window's backend already announces into the SHARED registry I built (it runs the + same server.ts), so `t3 instances` and the web instance switcher will list desktop-launched + instances automatically — no extra desktop code needed for DISCOVERY, only for the + spawn-new-window UX. +CONFIDENCE on desktop: LOW (no typecheck; OAuth deep-link correctness at stake).
