TCS Ordering: `IsProcessing = false` BEFORE `TrySetResult` + +**Where:** `CopilotService.Events.cs` β†’ `CompleteResponse()` and `SessionErrorEvent` handler + +**The rule:** When completing a response via the TaskCompletionSource (TCS), you MUST set `IsProcessing = false` BEFORE calling `TrySetResult()` or `TrySetException()`. + +**Why:** In reflection loops, the TCS continuation runs **synchronously**. The next `SendPromptAsync` in the loop checks `IsProcessing` β€” if it's still `true`, it throws "already processing". This killed reflection loops after 1 iteration. + +```csharp +// βœ… CORRECT ORDER +state.IsProcessing = false; // 1. Clear flag first +state.ResponseCompletion?.TrySetResult(response); // 2. Then signal completion + +// ❌ WRONG β€” breaks reflection loops +state.ResponseCompletion?.TrySetResult(response); // Continuation runs NOW +state.IsProcessing = false; // Too late β€” next SendPromptAsync already threw +``` + +**Same rule applies to error paths** (`TrySetException`). + +### 2. Reconciliation Must Not Scatter Multi-Agent Sessions + +**Where:** `CopilotService.Organization.cs` β†’ `ReconcileOrganization()` + +**The rule:** Sessions that belong to multi-agent groups must NOT be auto-moved to repo groups during reconciliation. Two protections: + +1. **Active group members**: If a session's `GroupId` matches any `IsMultiAgent` group, skip it +2. **Orphaned multi-agent sessions** (group was deleted): If `Role == Orchestrator` or `PreferredModel != null`, don't auto-move to repo groups β€” these markers indicate the session was part of a multi-agent group + +**Why:** Reconciliation runs twice on startup (once in `LoadOrganization`, once after `RestorePreviousSessionsAsync`). Without protection, it redistributes multi-agent sessions across repo-based groups, destroying the team. + +### 3. Never Edit `organization.json` While the App Is Running + +**Why:** The app calls `SaveOrganization()` from ~30 places, constantly overwriting the file with its in-memory state. Any external edits are lost within seconds. To fix organization state: kill app β†’ edit file β†’ relaunch. + +### 4. Sentinel Protocol Is Case-Insensitive But Must Be on Its Own Line + +**Sentinels:** +- `[[GROUP_REFLECT_COMPLETE]]` β€” Goal achieved, stop iterating +- `[[NEEDS_ITERATION]]` β€” More work needed, continue +- `[[REFLECTION_COMPLETE]]` β€” Single-agent reflection goal met + +**Detection:** `StringComparison.OrdinalIgnoreCase` for multi-agent; strict regex `^\s*\[\[REFLECTION_COMPLETE\]\]\s*$` (multiline) for single-agent. + +### 5. Worker Prompt Must Include Original User Request + +**Where:** `ExecuteWorkerAsync` (line ~772) + +**Why:** Workers receive only their assigned subtask from the orchestrator. Without the original user request as context, they can't understand the broader goal. The prompt format is: + +``` +You are a worker agent. Complete the following task thoroughly. + +## Original User Request (context) +{originalPrompt} + +## Your Assigned Task +{task} +``` + +--- + +## Stall Detection + +Two mechanisms, both in `ReflectionCycle.CheckStall()`: + +1. **Exact hash match** β€” Sliding window of last 5 response hashes. If current hash matches any β†’ stall. +2. **Jaccard token similarity** β€” Tokenize current and previous response by whitespace. If intersection/union > 0.9 β†’ stall. + +**Tolerance:** 2 consecutive stalls required before stopping. First stall generates a warning.

This happened because AssistantTurnStartEvent resets ActiveToolCallCount to 0 between tool rounds, making the model's 'thinking' gap between tools look like inactivity. Added HasUsedToolsThisTurn flag that stays true for the entire processing cycle once any tool executes. The watchdog now uses the 600s tool timeout when: a tool is actively running (hasActiveTool), the session was resumed mid-turn (IsResumed), or tools have been used this turn (HasUsedToolsThisTurn).
