-# CalendarScheduler Refactor Plan (v2)
+# CalendarScheduler Refactor Plan
 
-> Updated 2026-04-19 based on architecture discussion with hang
+## Current Design
 
-## Current Issues
+```
+Every 60s:
+  heartbeat() → POST /calendar/agent/heartbeat → returns pending slots
+  if idle → select highest priority → executeSlot → wakeAgent(spawn)
+  if busy → defer all pending slots
+```
 
-1. `process.env.AGENT_ID` doesn't exist in plugins subprocess — always 'unknown'
+**Problems:**
-2. Heartbeat is per-agent but should be per-claw-instance (global)
+1. Every heartbeat queries backend for pending slots — no local awareness of full schedule
-3. Scheduler only handles one agent — should manage all agents on this instance
+2. Cannot detect slots assigned by other agents between heartbeats
-4. wakeAgent used api.spawn (non-existent) → now uses dispatchInboundMessage (verified)
+3. 60s interval is too frequent for sync but too infrequent for precise wakeup
+4. Wakeup via `api.spawn()` creates a plain session, not a Discord private channel
 
 ## Target Design
 
-### Plugin State
+```
+Every 5-10 min (sync interval):
+  syncSchedule() → GET /calendar/day → update local today cache
+
+Every 30s (check interval):
+  checkDueSlots() → scan local cache for due slots
+  if due slot found:
+    confirmAgentStatus() → GET /calendar/agent/status
+    if not busy → wakeAgent (via Dirigent moderator bot private channel)
+```
+
+## Changes Required
+
+### 1. Add Local Schedule Cache
+
+New class `ScheduleCache`:
+```typescript
+class ScheduleCache {
+  private slots: Map<string, CalendarSlotResponse>;  // slotId → slot
+  private lastSyncAt: Date | null;
+
+  async sync(bridge: CalendarBridgeClient): Promise<void>;  // fetch today's full schedule
+  getDueSlots(now: Date): CalendarSlotResponse[];  // scheduled_at <= now && NOT_STARTED/DEFERRED
+  updateSlot(id: string, update: Partial<CalendarSlotResponse>): void;  // local update
+  getAll(): CalendarSlotResponse[];
+}
+```
+
+### 2. Add CalendarBridgeClient.getDaySchedule()
+
+New endpoint call:
+```typescript
+async getDaySchedule(date: string): Promise<CalendarSlotResponse[]>
+// GET /calendar/day?date=YYYY-MM-DD
+```
+
+This fetches ALL slots for the day, not just pending ones. The existing `heartbeat()` only returns NOT_STARTED/DEFERRED.
+
+### 3. Split Heartbeat into Sync + Check
+
+**Replace** single `runHeartbeat()` with two intervals:
 
 ```typescript
-// Local schedule cache: { agentId → [slots] }
+// Sync: every 5 min — pull full schedule from backend
-const schedules: Map<string, CalendarSlotResponse[]> = new Map();
+this.syncInterval = setInterval(() => this.runSync(), 300_000);
+
+// Check: every 30s — scan local cache for due slots
+this.checkInterval = setInterval(() => this.runCheck(), 30_000);
 ```
 
-### Sync Flow (every 5 min)
+`runSync()`:
+1. `bridge.getDaySchedule(today)` → update cache
+2. Still send heartbeat to keep backend informed of agent liveness
 
-```
+`runCheck()`:
-1. GET /calendar/sync?claw_identifier=xxx
+1. `cache.getDueSlots(now)` → find due slots
-   - First call: server returns full { agentId → [slots] }
+2. Filter out session-deferred slots
-   - Subsequent: server returns diff since last sync
+3. If agent idle → select highest priority → execute
-2. Update local schedules map
-3. Scan schedules for due slots:
-   for each agentId in schedules:
-     if has slot where scheduled_at <= now && status == not_started:
-       getAgentStatus(agentId, clawIdentifier) → busy?
-       if not busy → wakeAgent(agentId)
-```
 
-### Heartbeat (every 60s)
+### 4. Wakeup via Dirigent (future)
 
-Simplified to liveness ping only:
+Change `wakeAgent()` to create a private Discord channel via Dirigent moderator bot instead of `api.spawn()`. This requires:
-```
+- Access to Dirigent's moderator bot token or cross-plugin API
-POST /monitor/server/heartbeat
+- Creating a private channel with only the target agent
-  claw_identifier: xxx
+- Posting the wakeup prompt as a message
-  → server returns empty/ack
-```
 
-No slot data in heartbeat response.
+**For now:** Keep `api.spawn()` as the wakeup method. The Dirigent integration can be added later as it requires cross-plugin coordination.
-
-### Wake Flow
-
-```
-dispatchInboundMessage:
-  SessionKey: agent:{agentId}:hf-wakeup
-  Body: "You have due slots. Follow the hf-wakeup workflow of skill hf-hangman-lab to proceed. Only reply WAKEUP_OK in this session."
-
-Agent reads workflow → calls hf tools → sets own status to busy
-```
-
-### Agent ID Resolution
-
-- **Sync**: agentId comes from server response (dict keys)
-- **Wake**: agentId from local schedules dict key
-- **Tool calls by agent**: agentId from tool ctx (same as padded-cell)
-
-## Backend API Changes Needed
-
-### New: GET /calendar/sync
-
-```
-GET /calendar/sync?claw_identifier=xxx
-Headers: X-Claw-Identifier
-
-Response (first call):
-{
-  "full": true,
-  "schedules": {
-    "developer": [slot1, slot2, ...],
-    "operator": [slot3, ...]
-  },
-  "syncToken": "abc123"
-}
-
-Response (subsequent, with ?since=abc123):
-{
-  "full": false,
-  "diff": [
-    { "op": "add", "agent": "developer", "slot": {...} },
-    { "op": "update", "agent": "developer", "slotId": 5, "patch": {...} },
-    { "op": "remove", "agent": "operator", "slotId": 3 }
-  ],
-  "syncToken": "def456"
-}
-```
-
-### Existing: POST /calendar/agent/status
-
-Keep as-is but ensure it accepts agentId + clawIdentifier as params:
-```
-POST /calendar/agent/status
-  { agent_id, claw_identifier, status }
-```
 
 ## Implementation Order
 
-1. Backend: Add /calendar/sync endpoint
+1. Add `ScheduleCache` class (new file: `plugin/calendar/schedule-cache.ts`)
-2. Plugin: Replace CalendarBridgeClient single-agent design with multi-agent
+2. Add `getDaySchedule()` to `CalendarBridgeClient`
-3. Plugin: Replace CalendarScheduler with new sync+check loop
+3. Refactor `CalendarScheduler`:
-4. Plugin: wakeAgent uses dispatchInboundMessage (done)
+   - Replace single interval with sync + check intervals
-5. Plugin: Tool handlers get agentId from ctx (like padded-cell)
+   - Use cache instead of heartbeat for slot discovery
+   - Keep heartbeat for agent liveness reporting (reduced frequency)
+4. Update state persistence for new structure
+5. Keep existing wakeAgent/completion/abort/pause/resume tools unchanged
 
-## Files to Change
+## Files to Modify
 
-### Backend (HarborForge.Backend)
+| File | Changes |
-- New route: `/calendar/sync`
+|------|---------|
-- New service: schedule diff tracking per claw_identifier
+| `plugin/calendar/schedule-cache.ts` | New file |
+| `plugin/calendar/calendar-bridge.ts` | Add `getDaySchedule()` |
+| `plugin/calendar/scheduler.ts` | Refactor heartbeat → sync + check |
+| `plugin/calendar/index.ts` | Export new types |
 
-### Plugin
+## Risk Assessment
-- `plugin/calendar/calendar-bridge.ts` — remove agentId binding, add sync()
+
-- `plugin/calendar/scheduler.ts` — rewrite to multi-agent sync+check
+- **Low risk:** ScheduleCache is additive, doesn't break existing behavior
-- `plugin/calendar/schedule-cache.ts` — already exists, adapt to multi-agent
+- **Medium risk:** Splitting heartbeat changes core scheduling logic
-- `plugin/index.ts` — update wakeAgent, getAgentStatus to accept agentId
+- **Mitigation:** Keep `heartbeat()` method intact, use it for liveness reporting alongside new sync
