Merge Risk: 🟡 Moderate · up to Built-in Cursor, Copilot, and Grok agents may fail to start when they are not explicitly configured. Custom-named instances using a legacy driver may start with the wrong arguments. Fix flavor resolution before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The shared driver preserves important controls for the default built-in providers, and the database migration preserves session identities. However, legacy providers with custom instance names can lose their provider-specific behavior during normalization, including Copilot’s restricted-mode permission guard. The impact depends on whether the configured executable successfully starts ACP. Custom-provider enforcement and the exact previous behavior remain partially unresolved. Retained concerns

A named instance with driver: "cursor" is converted to ACP without retaining its Cursor flavor. Startup then passes none of the required Cursor ACP, workspace, or sandbox arguments to cursor-agent, breaking that existing provider configuration. This must be fixed before merging.
Knowledge Base Used: Agent runtime and provider adapters
Artifacts
Focused Cursor parse and child-process reproduction script
- The authored script runs the actual parser and driver path in both modes using a mock executable, showing how the two captures were produced.
Current code: Cursor child launched without ACP arguments
- Running the tracked parser and driver produced a successful mock runtime but child args `[]`, confirming the missing Cursor flavor.
Temporary correction: Cursor child launched with ACP arguments
- Running a temporary parser copy that preserves the legacy driver flavor produced the expected Cursor ACP and sandbox arguments.

The filter removes a configured provider whose ID is acp, even when its command is available. The catalog marks it unusable and onboarding omits it; configured Cursor, Copilot, and Grok providers instead appear twice. Valid provider discovery must be restored before merging.

Knowledge Base Used: Agent discovery, availability, and profiles
Artifacts
Parsed-config runtime test script
- The authored command imports the checkout for the before run and an isolated corrected copy for the after run, testing snapshot, catalog, and onboarding data.
Runtime output with the PR filter
- The executed checkout omitted configured `acp`, duplicated three legacy IDs, and marked `acp` unusable in the catalog.
Isolated snapshot source with corrected filter
- The generated source changes the filter without editing tracked files, providing the source executed in the after run.
Runtime output with the corrected filter
- The executed isolated source returned each configured ID once and marked `acp` usable, confirming the filter causes the observed behavior.

For a cursor provider configured with Grok flavor and no command override, availability checks cursor-agent while startup selects grok. A runnable provider can be rejected, or a provider can pass preflight only to fail at startup. The checks must agree before merging.
Knowledge Base Used: Agent discovery, availability, and profiles
Artifacts
Authored cursor and grok verification script
- The executed script creates a controlled PATH and tests original and temporary flavor-aware preflight code against runtime resolution, showing how the comparison was made.
Original preflight and runtime results
- The original source was executed with each executable alone; preflight and runtime disagreed in both cases.
Flavor-aware preflight and runtime results
- A temporary flavor-aware copy was executed under the same conditions; preflight and runtime agreed in both cases.

Calling the exported createLocalAgentDrivers() without subagent configuration creates Cursor, Copilot, and Grok drivers without flavors. Each reports its executable missing even when it is on PATH, making this fallback factory path unusable. The daemon's configured path is unaffected; this is a non-blocking concern.
Artifacts
Executable-shim driver reproduction script
- The authored script constructs drivers through both paths and attempts ACP startup, showing how executable selection was tested.
Normalized drivers start the executables
- The captured command ran normalized cursor, copilot, and grok drivers; all started their shims before ACP initialization failed.
Unconfigured drivers report executables missing
- The captured command ran the exported factory without subagents; all three drivers reported unavailable without starting their shims.

The published schema accepts an enabled ACP provider such as kiro without a command, but runtime configuration parsing rejects it. Editor validation can therefore approve a configuration that DevSpace cannot load. This validation mismatch is a non-blocking concern.
Knowledge Base Used: Configuration and onboarding flow
Artifacts
Executable schema and runtime comparison script
- The authored script validates a full config document with installed Ajv and parses that document with the runtime schema, providing the executed source for both conditions.
Validation output with command missing
- Running the script without a command produced Ajv acceptance and runtime rejection at the provider command path, confirming the mismatch.
Validation output with command supplied
- Running the same script with `command: "kiro"` produced acceptance by both validators, isolating the missing command as the difference.

⚠️ Unverified finding
Verification did not complete.Verify write-mode enforcement when
config.argsreplaces generated arguments.When a built-in ACP instance sets
config.args, this line omits the generated sandbox and read-only flags. The permission callback rejects read-only permission requests, but that control is insufficient if the provider can write without making a request. Confirm the behavior of each supported built-in executable without those flags. If writes remain possible, preserve the required write-mode flags when adding configured arguments.

Supply the built-in ACP flavor when instance configuration omits it.
createLocalAgentDrivers() creates Cursor, Copilot, and Grok instances without config.flavor. This factory passes undefined, so each driver becomes generic and has no default executable. updateOnboardingSubagentsConfig can construct the same flavorless instances. Fall back to the legacy provider ID for these three instances before constructing AcpLocalAgentDriver.

Exclude default provider IDs from the custom availability entries.
When configuration contains cursor, copilot, or grok, this expression adds the configured instance once as a default. The following filter adds it again because those IDs are no longer driver kinds. Filter custom instances against LOCAL_AGENT_DEFAULT_PROVIDER_IDS so the snapshot reports each instance once.

Derive ACP flavor from the resolved driver and legacy driver.
For { id: "cursor-work", driver: "cursor", command: "cursor-agent" }, parsing changes the driver to acp but leaves the flavor unset. The runtime then uses generic arguments instead of Cursor’s required acp arguments. Conversely, { id: "cursor", driver: "codex" } receives ACP configuration after schema validation. Infer a legacy flavor from provider.driver or the legacy ID only when the resolved driver is acp.
