fix(server): stop probing Grok, Cursor, and OpenCode unless turned on

[t3dotgg]

The Grok, Cursor, and OpenCode bindings have known issues, but every install probed them anyway: all five providers were enabled by default, so the server ran grok --version (and friends) on every health refresh even when the CLI was not installed.

On top of that, there were two enabled flags: the envelope-level providerInstances.<id>.enabled and the driver-config config.enabled. The envelope silently won, so disabling through one path did not stick.

Now:

• Grok and OpenCode default to enabled: false in their settings schemas, matching Cursor. Codex and Claude stay on. Disabled providers skip all probing and stay visible in Settings with the toggle to opt in.
• The envelope flag is the single enabled flag. The server folds a legacy config.enabled into the envelope on load/update and strips it; an explicit false on either side wins, so an existing disable is never undone.
• Clients resolve enablement through one shared helper (resolveProviderInstanceEnabled) instead of scattered enabled ?? true fallbacks.

Behavior note: users of Grok/Cursor/OpenCode who never touched provider settings will find the provider disabled after updating and need to flip it on once in Settings.

Note

Medium Risk
Changes default provider behavior and settings migration paths across server, contracts, and UI; incorrect enablement resolution could skip probes or ignore user disables, but behavior is heavily tested.

Overview
Grok, Cursor, and OpenCode no longer probe on every install: their settings schemas default enabled to false (Grok was previously on by default). Codex and Claude stay enabled by default. Install docs note the opt-in behavior.

Provider enablement is consolidated on the envelope providerInstances.<id>.enabled. The server folds legacy config.enabled into the envelope on load/normalize/update and strips it from the blob; explicit false on either side wins so disables stick. Shared helpers (resolveProviderInstanceEnabled, defaultEnabledForDriver) replace scattered enabled ?? true in the registry, web settings UI, and model-selection checks. Legacy-to-instance synthesis in settings omits in-config enabled so toggles can turn default-off providers on.

Upgrade note: users who relied on Grok/OpenCode probing without changing settings must enable them once in Settings.

Note

Disable Grok, Cursor, and OpenCode provider probing by default

• Changes the default enabled state for Grok and OpenCode settings schemas from true to false; Cursor was already false. These providers are now opt-in via Settings.
• Adds resolveProviderInstanceEnabled in settings.ts to unify enabled-state resolution: explicit false on either the envelope or in-config wins; otherwise falls back to per-driver defaults.
• Introduces foldProviderInstanceEnabledFlags in serverSettings.ts to normalize legacy in-config enabled flags into the envelope on load and update, stripping the flag from the config blob.
• Updates UI components and shared utilities to use resolveProviderInstanceEnabled instead of instance.enabled ?? true.
• Behavioral Change: Grok, Cursor, and OpenCode instances are now disabled on fresh or existing configs where enabled was not explicitly set to true.

📝 Walkthrough

Walkthrough

The PR centralizes provider enablement resolution, changes optional provider defaults, migrates legacy nested flags, updates runtime and web consumers, and adds coverage for precedence and disabled-state behavior.

Changes

Provider enablement

Layer / File(s)	Summary
Enablement contract and defaults packages/contracts/src/settings.ts, packages/contracts/src/settings.test.ts	Adds shared helpers for legacy flags, driver defaults, and false-first precedence. Grok and OpenCode become disabled by default. Tests cover built-in and unknown drivers.
Settings migration and runtime resolution apps/server/src/serverSettings.ts, apps/server/src/provider/Layers/ProviderInstanceRegistryLive.ts, apps/server/src/serverSettings.test.ts, apps/server/src/provider/Layers/*test.ts	Migrates nested config.enabled values to the instance envelope and removes the legacy field. Runtime instance creation applies the same precedence rules. Tests cover migration, snapshots, and optional-provider defaults.
Consumer alignment and documentation apps/web/src/components/settings/*, apps/web/src/providerInstances.ts, packages/shared/src/serverSettings.ts, docs/user/install.md	Web and shared server consumers use the common resolver. Installation documentation lists default-enabled and opt-in providers.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to a3ad3

The PR changes provider enablement defaults and migrates stored settings, but unresolved edge cases could leave custom providers with inconsistent enabled state or discard valid configuration values. These issues should be fixed before merge.

One interaction regression found in the settings UI: with the new most-restrictive resolveProviderInstanceEnabled rule, the enable Switch on a default provider card can no longer turn an off-by-default provider on, because the card's instance still carries the legacy config.enabled: false from the legacy provider blob. Details inline.

resolveProviderInstanceEnabled(entry) behavior for unknown-driver defaults
instead of independently falling back to typedConfig.enabled. Update
resolveEntryEnabled so registry, shared, and web consumers agree with the
registry’s disabled default for unknown drivers, and add a focused registry test
covering an unknown driver whose decoded configuration defaults enabled to
false.

In `@apps/server/src/serverSettings.ts`:
- Around line 77-98: Update the config handling around the enabled resolver so
config.enabled is folded into the instance and removed from restConfig only when
it is boolean; preserve non-boolean own enabled values in
ProviderInstanceConfig.config unchanged. Add a focused regression test covering
a non-boolean value such as "auto" through the relevant server settings load or
update path.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes the default enabled state for Grok, Cursor, and OpenCode providers from on to off, affecting runtime behavior for new installs and users without explicit settings. The migration logic and tests are comprehensive, but this default behavior change warrants confirmation of product intent.

Note

🤖 Fable 5 responding on behalf of Theo

Product intent confirmed: the Grok, Cursor, and OpenCode bindings have known issues, so they are deliberately opt-in until stabilized — including for users who have them installed. Codex and Claude stay on by default. This change was requested by Theo directly.
