In `@apps/web/src/features/block-agent/context/create-composer-controller.ts`:
- Around line 147-149: Move the network request in postSetConfigOption to a
TanStack Query mutation defined in the queries package, and use or inject that
mutation from the composer controller instead of calling
agentHarnessServiceClient.control directly. Preserve the existing
setConfigOption payload and undefined-on-failure behavior.
- Around line 150-155: Update the request handling around the result failure
branch in the composer controller to associate each configuration request with a
unique generation or session identity. Before clearing requestedConfigId,
requestedConfigValue, requestedConfigActionId, or showing the failure toast,
verify that the completed request still owns the current pending state; ignore
stale responses from older overlapping requests or previous sessions.
In `@apps/web/src/lib/service-clients/service-agent-harness/openapi.json`:
- Around line 13-34: Restore the legacy /agent-models/load route alongside
/agent-capabilities/discover in the API definition, preserving its existing
request and response contract for compatibility during mixed-version
deployments. Do not remove the new discovery route.
- Around line 1055-1067: Update AgentSetConfigOptionAction to accept a typed
string-or-boolean value, matching the Boolean settings advertised by the
capability response; apply the same schema change to the corresponding
definition near the second referenced section, while preserving existing string
option support.
In `@crates/agent_fold/src/domain/fold/config.rs`:
- Line 106: Update the metadata projection around ConfigCarrier and the
assignment to self.metadata.config_options so a missing configOptions field does
not overwrite existing config_options, model, or supported_models. Only apply
the projected snapshot when configOptions is present; if deserialization
currently defaults absence to an empty vector, change it to
Option<Vec<SessionConfigOption>> and return false for None, while preserving
updates for present responses.
In `@crates/agent_harness/src/domain/capability_discovery.rs`:
- Around line 199-203: Update AgentCapabilitiesServiceImpl::load so the
HarnessCapabilityAccess::can_use authorization check is bounded by its own
timeout before invoking MacrodCapabilityProbe::probe; preserve the existing
model_probe_timeout semantics for provider probing and map authorization timeout
failures through the existing discovery error contract.
In `@services/agent_harness_service/src/api.rs`:
- Line 173: Update api_router and agent_capabilities_router so the legacy
/agent-models/load endpoint remains available alongside
/agent-capabilities/discover during rollout. Preserve the existing handler
behavior and route both paths to the same capability-loading implementation
until all clients migrate.

Do not let a stale request clear the current request.
Two configuration changes can overlap. If the older request fails after the newer request starts, this branch clears the newer request state and shows an incorrect failure toast. A response from a previous session can cause the same result.
Track a unique request generation or session identity. Settle state only when the completed request still owns the pending state.

Keep the old discovery route during the API migration.
This change removes /agent-models/load from the unversioned API. Existing clients receive HTTP 404 after the service deploys. New clients also fail against an older service during a mixed-version rollout.
Keep a compatibility route until all clients use /agent-capabilities/discover, or stage this change as a versioned migration.

Add Boolean support to AgentSetConfigOptionAction.
The capability response advertises Boolean settings, but the action accepts only a string value for select-style settings. A client can discover a Boolean setting but cannot send its Boolean value.
Use a typed string-or-Boolean action value, or omit Boolean settings until the action path supports them.

Do not clear metadata when configOptions is absent.
ConfigCarrier accepts a missing configOptions field as Vec::new(). This assignment then clears config_options, model, and supported_models. Only replace metadata when the response contains a new configOptions snapshot.
Verify that every correlated ACP response includes this field. If not, deserialize it as Option<Vec<SessionConfigOption>> and return false for None.

Bound authorization separately from provider probing.
AgentCapabilitiesServiceImpl::load awaits HarnessCapabilityAccess::can_use before it starts tokio::time::timeout around MacrodCapabilityProbe::probe. Production VisibleHarnessAccess::can_use awaits HarnessServiceImpl::list_harnesses, which calls PgHarnessRepo::list_visible_harnesses. A stalled repository query can keep discovery pending beyond the 10-second model_probe_timeout.
The configured timeout is documented as a provider-probe timeout. Apply a separate timeout to can_use, or define a whole-operation deadline and update the timeout error contract.

Keep /agent-models/load during the rollout.
infra/stacks/agent-harness-service/agent_harness_service.ts uses two ECS tasks with 100% minimum and 200% maximum healthy capacity, so old and new tasks can serve requests concurrently. api_router mounts agent_capabilities_router without /agent-models/load; an existing client routed to a new task can receive a 404. Keep a compatibility route until all clients use /agent-capabilities/discover, or deploy both components atomically.

Changes live session control and discovery APIs plus provider request shaping for reasoning effort; behavior is gated on advertised config options but mis-routing could affect model quality or cost.
Overview
Adds reasoning effort as a first-class session setting: when the harness advertises a
thought_level/reasoning_effortselect via ACP, users can change it from the session composer and from Compose session before the first prompt (withsetConfigOptionqueued ahead of the initial prompt).Discovery and API: Model-only probing (
loadAgentModels/useAgentModelsQuery) is replaced by capability discovery (/agent-capabilities/discover,useAgentCapabilitiesQuery). Settings and launch flows still derive model lists viadiscoveredModels(), but the payload is the fullconfigOptionssnapshot. Session fold metadata now carriesconfigOptions, and control timeline / chips understandset_config_optionalongsideset_model.Composer plumbing:
AgentInput’smodelControlslot becomessessionControls(model + optional effort pills). The composer controller tracks in-flight config changes like model switches (setConfigOption→ harness control).In-memory agent:
AgentLoopaccepts optionalReasoningEffort, mapped into Anthropicoutput_config.effortand OpenAI reasoning fields (with prior mini/nano defaults when unset).Reviewed by Cursor Bugbot for commit b83f801. Bugbot is set up for automated code reviews on this repo. Configure here.
