If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe daemon now provides gated MCP memory tools for remembering, recalling, and forgetting memories. It uses configured embedding models, runs maintenance, and cleans up on shutdown. Chat and settings surfaces now expose memory management state. ChangesDaemon memory runtime
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR enables end-to-end agent memory creation, embedding, recall, and management, but the current UI can retain memory access across session or read-only changes and can apply stale capability data to another agent, risking incorrect memory operations. Tests also do not reliably exercise global pending-embedding maintenance, while a session update path can still overwrite completed state and emit duplicate events. These bounded correctness and validation risks should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Confidence Score: 3/5The PR should not merge until the chat dialog respects the agent’s memory configuration and memory_recall honors its advertised limit. The new chat surface permits memory edits when the feature is disabled and misreports embedding availability, while the new recall tool silently discards a supported caller input.

|---|---|
| apps/daemon/src/host/daemonMemoryRuntime.ts | Adds configured-model embedding drains and the memory tool surface, but silently ignores memory_recall’s declared limit argument. |
| apps/daemon/src/index.ts | Initializes memory maintenance and integrates gated memory tools into Pi worker registration and dispatch. |

### Issue 1
packages/ui/src/components/chat/ChatTopBar.tsx:524-530
**Memory capability state is omitted**
When the active Argos agent has memory disabled or has an embedding model configured, this dialog omits `memoryEnabled` and `hasEmbeddingConfigured`, so it still permits memory edits and incorrectly displays the missing-embedding warning once memories exist.
### Issue 2
apps/daemon/src/host/daemonMemoryRuntime.ts:345-347
**Recall limit is discarded**
When `memory_recall` supplies the advertised `limit` argument, this branch forwards only the query, causing recall to return the agent-configured `topK` count rather than the number requested by the caller.

In `@apps/daemon/src/host/acp-provider-execution.ts`:
- Around line 197-203: Remove the later generating-status update in sendMessage,
including the setSessionStatus call and sessionsStatusChangedEvent.publish block
after runTurn starts; retain the earlier generating-status update before runTurn
and leave the idle-status handling unchanged.
In `@apps/daemon/src/host/daemonMemoryRuntime.ts`:
- Around line 297-299: Update the memory_forget tool description and its
deleteMemory behavior to use matching semantics: either archive the identified
memory instead of permanently deleting it, or explicitly describe the tool as
permanently deleting the memory. Keep the change scoped to memory_forget and its
corresponding operation.
- Around line 293-296: Update the memory_recall tool and its recall path so the
caller-provided limit is honored, constraining results to that validated value
instead of the default topK. Trace the limit through the relevant memory recall
method(s), preserving the existing 1–20 bounds, or remove the limit field from
the tool schema if it cannot be supported.
In `@apps/daemon/src/index.ts`:
- Around line 337-343: Update the memory-tool dispatch in the request handling
flow to resolve the effective agent configuration after loading the session,
then reject the call unless that configuration has memoryEnabled === true.
Preserve the existing active-session/agent validation and only invoke
memoryRuntime.callMemoryTool after both checks pass.
- Around line 1037-1038: Update the setupGracefulShutdown shutdown callback to
stopBackgroundMaintenance and dispose the memory presenter before closing the
database, matching the cleanup already used in close. Reuse the existing
memoryRuntime.presenter cleanup behavior in both shutdown paths.
In `@docs/features/memory-real-implementation/plan.md`:
- Line 13: Update the diagram’s fenced code block in the documentation to
specify the text language, using a text-labeled fence so markdownlint rule MD040
passes while preserving the ASCII diagram content.
In `@docs/features/memory-real-implementation/spec.md`:
- Around line 42-43: Update the memory real-implementation specification to
require stopping background maintenance during daemon shutdown, and add
corresponding shutdown-lifecycle entries to the plan and tasks documents.
Reference MemoryPresenter.startBackgroundMaintenance() and the daemon shutdown
flow, preserving the existing startup criterion.
In `@docs/features/pi-worker-permission-terminate/plan.md`:
- Line 27: Update the testing statement in the plan to say that
apps/daemon/test/piWorker.test.ts covers worker startup only; retain the
existing requirement for a regression test covering the deny/terminate: true
permission path.

Pull request overview
This PR activates the previously-inert agent memory subsystem in the daemon runtime and surfaces it in the UI. Memories added via the UI are now actually embedded into the DuckDB vector store, the daemon Pi worker loop gains memory_remember/memory_recall/memory_forget tools (gated on memoryEnabled), background consolidation maintenance is started/stopped with the daemon lifecycle, and the memory manager becomes reachable from the chat top bar.
Changes:
DaemonMemoryRuntime: drains pending embeddings after insert, uses the agent's configured embeddingmodelId(no longer hard-coded), and exposes an MCP-style memory tool surface (toolDefinitions/handlesTool/remember/recall/forget/callMemoryTool).apps/daemon/src/index.ts: constructsmemoryRuntimeearlier, starts/stops background maintenance and disposes on close, appends memory tools whenmemoryEnabled === true, and dispatchesmemory_*tool calls by resolving the agent from the session.- UI:
ChatTopBaradds a Memory button openingMemoryManagerDialog;ArgosAgentsSettingspassesmemoryEnabled/hasEmbeddingConfiguredto fix the dialog banners.

setMemoryCapabilities, while preserving the existing dialog behavior for the

- Around line 548-557: Update the MemoryManagerDialog rendering in ChatTopBar so
it requires canManageMemory in addition to currentSession?.agentId. Close and
reset the memory dialog state whenever the session or memory-management
eligibility changes, preventing an already-open dialog from receiving a
different agent or remaining open in read-only mode.
