Summary

  • Add abbenay.daemonMode with auto (default), embedded, standalone, remote, and disabled; select the daemon connection/startup behavior and reconnect when settings change.
  • Isolate embedded daemon IPC and its dashboard port. Local auto/standalone requests reuse the selected daemon's reported dashboard URL (including custom ports); embedded requests use a distinct port. Remote dashboard routing preserves the reported port, and missing response URLs are derived from the returned port for older daemons. Failures do not fall back to another instance.
  • Disabled mode skips daemon startup, connection, and Language Model API registration while leaving Abbenay commands and views available; switching to Disabled closes existing transports.
  • Add regression tests for daemon modes, Disabled disconnect, embedded/custom remote/local dashboard port routing, missing response URL fallback, dashboard action errors, omitted-port idempotence, and Windows-safe runtime paths.
  • Update VS Code tooling/lockfile and scoped Mocha dependency overrides to eliminate dependency advisories; no audit allowlist entries were added.
  • The session index remains shared by concurrent daemon instances. Track this deferred race in fix(daemon): isolate session storage across daemon instances #139 while session support is being removed.
  • Watch daemon settings during activation startup; if Disabled is selected in flight, close the new transport before registering providers.

Commits

  • feat(vscode): let users disable the daemon provider — add all daemon modes, Disabled behavior, tests/docs, and dependency audit remediation.
  • fix(vscode): keep embedded dashboards isolated — isolate embedded IPC/dashboard behavior and track the deferred session-store race in fix(daemon): isolate session storage across daemon instances #139.
  • fix(vscode): preserve dashboard open behavior — avoid duplicate opens and handle dashboard action failures.
  • fix(vscode): preserve custom dashboard behavior — keep dashboard response routing tied to the selected daemon.
  • fix(vscode): use existing custom dashboard ports — preserve daemon-reported local and remote ports.
  • fix(vscode): preserve daemon dashboard ports — keep omitted-port calls idempotent while rejecting explicit port conflicts.
  • fix(vscode): resolve daemon dashboard response ports — derive URLs when older daemons omit response fields and prevent test settings leaking.
  • fix(vscode): handle settings changed during startup — roll back startup when Disabled is selected in flight.

Test plan

  • npm run lint
  • npm test — daemon: 1,317 passed, 1 skipped; VS Code: 62 passed
  • npm run ci:build
  • npm run test:coverage -w packages/daemon
  • npm run audit:check — zero new advisories
  • Targeted dashboard service/runtime-path tests (130 passed)
  • git diff --check

Assisted-by: Copilot SDK / GPT-6 Luna

Add a disabled daemon mode for bundled installations.

It avoids daemon startup and model registration unless users opt in.

Test the disabled connect path.

Update vulnerable VS Code packaging and test dependencies.

Pin patched Mocha transitive packages to pass audit.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added the abbenay.daemonMode setting with auto, embedded, standalone, remote, and disabled options.
    • Added mode-specific daemon startup, connection, reconnection, and runtime behavior.
    • Embedded mode uses an isolated runtime environment and dashboard port.
    • Remote mode supports configured daemon addresses, while standalone mode connects to an existing daemon.
    • Disabled mode prevents daemon connections and language-model registration.
    • Dashboard startup now uses the selected mode’s settings and reports the active port.
  • Bug Fixes

    • Improved dashboard handling when a daemon is already running.
  • Documentation

    • Documented daemon modes, connection behavior, reconnection, and configuration details.
    • Added decision records covering daemon modes and tooling updates.

The VS Code extension adds five daemon modes with mode-specific runtime paths, startup, connection, dashboard, disabled-mode, and reconnection behavior. Tests and documentation cover these changes. VS Code tooling and npm overrides are also updated.

Confirmed: both daemon processes share the session directory, and the current per-process lock does not provide cross-process safety. Per maintainer direction, session support is being removed rather than adding new session-store synchronization in this PR. Tracked in #139; leaving this thread open for human review until that follow-up lands.

Medium severity Avoid forcing port 8787 for implicit local dashboard requests

packages/​vscode/​src/​daemon/​client.ts:879

If the selected local daemon already serves a dashboard started with abbenay web --port 3000, Open Dashboard now fails with ALREADY_EXISTS. This converts an omitted port into an explicit 8787 request, which the new server-side mismatch check rejects instead of returning the existing dashboard URL. Send 0 (no port preference) for implicit auto/standalone local requests, while preserving explicit ports and embedded mode's isolated port. Add a regression test for opening an existing custom-port dashboard.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Probe the Unix socket before treating the daemon as ready.

The new embedded mode calls isDaemonReady(this.localMode). On Unix, that check validates the PID and socket-file existence but does not connect to the socket. If the PID still exists and the socket is stale, connect() skips startDaemon(), then initializeDaemon() fails on register(). Users cannot connect until the stale files are removed.

Handle a false result from openExternal.

vscode.env.openExternal can resolve false when VS Code does not open the URI. openDashboardForClient ignores this result and returns normally. The connected command then logs the dashboard as opening instead of entering its error path. Promise rejections are already handled by the existing await and try/catch.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Await and report the fallback open result.

When the daemon is disconnected and dashboardFallback is defined, this branch calls vscode.env.openExternal(...) and returns without awaiting it. A rejected Thenable can bypass the command's error handler, and a resolved false result is ignored. Await the call and report a failed result through the existing error path.

Medium severity Preserve daemon-advertised dashboard port during host replacement

packages/​vscode/​src/​daemon/​connection-config.ts:22

This replaces the daemon's returned dashboard port with 8787 for every configured address. For example, daemonAddress = localhost:50051 with a dashboard on 3000 now opens http://localhost:8787; the previous implementation preserved the returned URL in this case. This can open the wrong instance or an unused port. Replace only the hostname, preserving the advertised port, and update the remote-routing test to cover a custom port.

Ask local daemons for their current dashboard port instead of forcing 8787.

Keep the isolated port for embedded mode and test port selection.

🔵 Needs a closer look

Configured localhost connections discard returned custom dashboard ports and can open the wrong daemon's dashboard.

2 open issues

In code that hasn't changed since last review

Medium severity Preserve custom-port localhost dashboard URLs

packages/​vscode/​src/​daemon/​connection-config.ts:22

With daemonAddress: "localhost:50051" and an existing dashboard on port 3000, this replaces the returned http://localhost:3000 with http://localhost:8787. The previous command preserved the returned URL for this localhost endpoint, so this breaks custom-port dashboards and can open another daemon's dashboard. Preserve the returned URL when the derived endpoint is the default localhost URL, and add an address-based localhost/custom-port regression test.

Medium severity Clarify missing remote address configuration warning

packages/​vscode/​src/​extension.ts:328

This branch also runs when daemonMode is remote but daemonAddress is missing or invalid: connection initialization fails and resolveDashboardUrl() returns undefined. The warning incorrectly says Abbenay is disabled instead of explaining how to fix the configuration. Distinguish Disabled mode from a missing remote address.

Preserve the daemon's actual dashboard port for remote connections.

When a reachable remote daemon already serves its dashboard on a custom port, StartWebServer returns that port, but dashboardUrlForConnection replaces it with fixed port 8787. openDashboardForClient then opens the wrong URL. Preserve response.port while still replacing the daemon's localhost host with the configured remote host.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject dashboard requests while daemon mode is disabled.

abbenay.openDashboard can run while the existing client remains connected during asynchronous reconnect cleanup. startWebServer() then sends the dashboard RPC without checking the current mode. The daemon handles that RPC by starting the web server or returning its existing instance.

Suggested fix
   async startWebServer(port?: number): Promise<proto.StartWebServerResponse> {
-    const client = this.getClient();
     const config = readDaemonConnectionConfig();

Startup cancellation and dashboard endpoint handling still have correctness issues.

Medium severity Clear failed dashboard listen state before retrying

packages/​daemon/​src/​daemon/​server/​abbenay-service.ts:1355

The same-port check can accept a dashboard that failed to start. daemon/web/server.ts sets _webPort and _httpServer before listening succeeds, leaves them set on error, and treats any non-null server as running. If another process owns port 8788, the first embedded dashboard attempt fails, but a second returns already_running and opens that other process's service. Clear failed-listen state and test two consecutive attempts against an occupied port; both must report failure rather than return a dashboard URL.

Fill the dashboard URL and port from the daemon response when older servers omit either field.

Keep custom-port dashboard discovery test state from leaking into later tests.

Watch daemon settings before startup begins.

Roll back transports if Disabled is selected while startup is pending.

Preserve effective default ports in remote dashboard URL rewrites.

Test startup-time disable and port 80 normalization.

Critical — Security / Functionality: shared session index across daemon instances

Embedded mode isolates IPC/runtime here (ABBENAY_RUNTIME_DIR / optional XDG_RUNTIME_DIR), but spawned daemons still use the same user config tree as auto/standalone (SessionStore → getSessionsDir() in packages/daemon/src/daemon/state.ts). Two live daemons can interleave writes to index.json and per-session files.

PR text defers this to #139; until session storage is removed or isolated per instance, running embedded alongside another local daemon (or switching modes without a clean shutdown) is a data-corruption risk and should not ship without an explicit waiver.

Critical — Security: disconnected dashboard opens a guessed loopback URL

When !client.isConnected(), this branch opens dashboardFallback from resolveDashboardUrl() (e.g. http://localhost:8787 or embedded 8788) without validating the selected daemon. Any process already listening on that port can receive the browser session—including the dashboard API if HTTP auth is disabled or cookies apply.

Ask: Fail closed when disconnected (or require a successful startWebServer / health check on the selected instance). Do not open a static default port.
