# Comprehensive Report: OpenCode Task Delegation, Subagent Communication, and Error Handling

## 1. Task Tool Implementation — How Subagents Are Spawned

### File: `/home/jm/data/code/opencode/packages/opencode/src/tool/task.ts`

The `TaskTool` is defined using `Tool.define("task", ...)`. There is **no separate `background_task`** tool -- OpenCode has only the `task` tool (and a `subtask` mechanism for slash command invocations).

**Spawning flow:**

```
TaskTool.execute()
  1. Permission check via ctx.ask() — unless bypassed by user @ mention
  2. Agent.get(params.subagent_type) — resolve the subagent config
  3. Session.create({ parentID: ctx.sessionID, ... }) — create a CHILD session
     - OR resume an existing session if params.task_id is provided
  4. SessionPrompt.prompt({ sessionID: child.id, ... }) — run the subagent's LLM loop
  5. Extract last text part from result
  6. Return structured output with task_id for potential resumption
```

Key code at lines 66-102 (session creation):
```typescript
const session = await iife(async () => {
  if (params.task_id) {
    const found = await Session.get(params.task_id).catch(() => {})
    if (found) return found
  }
  return await Session.create({
    parentID: ctx.sessionID,                    // <-- parent-child link
    title: params.description + ` (@${agent.name} subagent)`,
    permission: [
      { permission: "todowrite", pattern: "*", action: "deny" },
      { permission: "todoread", pattern: "*", action: "deny" },
      ...(hasTaskPermission ? [] : [{ permission: "task", pattern: "*", action: "deny" }]),
      // ... experimental primary tools
    ],
  })
})
```

Key code at lines 128-143 (invoking the subagent LLM loop):
```typescript
const result = await SessionPrompt.prompt({
  messageID,
  sessionID: session.id,  ...

Now let me provide the user with a concise answer based on my research:

Based on my deep research of current AI coding assistants (Cursor, Windsurf, Aider) and agent orchestration frameworks (LangGraph, CrewAI, AutoGen), here are the **top 5 most relevant patterns** for resilient task delegation in OpenCode:

## 🏆 Top 5 Patterns for OpenCode Implementation

### 1. **Durable Execution with Checkpointing** (Highest Impact)
**What**: Save agent state after each step to enable recovery from crashes/timeouts
**How**: Persist conversation history, plan state, subagent state, execution context
**OpenCode Fit**: Extend session storage with periodic snapshots
```typescript
// Example: Checkpoint after each tool call
interface Checkpoint {
  sessionId: string;
  step: number;
  state: AgentState;
  timestamp: number;
}
```

### 2. **Circuit Breaker with Exponential Backoff** (Critical for APIs)
**What**: Prevent repeated calls to failing LLM APIs with progressive delays
**How**: Track failures → OPEN circuit → exponential backoff → HALF_OPEN testing
**OpenCode Fit**: Wrap `Tool.execute()` calls with failure tracking
```typescript
// States: CLOSED (normal), OPEN (blocked), HALF_OPEN (testing)
// Backoff: 500ms → 1s → 2s → 4s → 8s
```

### 3. **Dead Letter Queue (DLQ) with Manual Intervention** (Essential for Stuck Tasks)
**What**: Move failed tasks (3+ attempts) to quarantine for human review
**How**: Store error context + recovery options (retry/modify/cancel/escalate)
**OpenCode Fit**: Add DLQ storage + UI for inspecting stuck subagents
```typescript
interface DeadLetterTask {
  taskId: string;
  error: string;
  attempts: number;
  recoveryOptions: {
    retryWithModifiedConfig?: boolean;
    forceCompleteWithResult?: string;
    cancelAndReturnError?: boolean;
  };
}
```

### 4. **Hierarchical Timeout with Graceful Degradation** (Multi-level Protection)
**What**: Nested...

Now I have everything needed. Here is the complete analysis:

---

# OpenCode Plugin API -- Complete Reference

## 1. Plugin Type Definition

**File:** `/home/jm/data/code/opencode/packages/plugin/src/index.ts`

A plugin is a function that receives a `PluginInput` and returns `Hooks`:

```typescript
export type Plugin = (input: PluginInput) => Promise<Hooks>
```

### PluginInput (the "ctx" when initializing a plugin)

```typescript
export type PluginInput = {
  client: ReturnType<typeof createOpencodeClient>  // OpencodeClient SDK instance
  project: Project                                  // Current project info
  directory: string                                 // Project directory
  worktree: string                                  // Git worktree root
  serverUrl: URL                                    // Local server URL
  $: BunShell                                       // Bun shell (Bun.$)
}
```

### Hooks (the return value -- what a plugin can register)

```typescript
export interface Hooks {
  event?: (input: { event: Event }) => Promise<void>
  config?: (input: Config) => Promise<void>

  tool?: {                                // Custom tool definitions
    [key: string]: ToolDefinition
  }

  auth?: AuthHook                         // Provider authentication

  "chat.message"?: (                      // Intercept new user messages
    input: { sessionID; agent?; model?; messageID?; variant? },
    output: { message: UserMessage; parts: Part[] },
  ) => Promise<void>

  "chat.params"?: (                       // Modify LLM parameters
    input: { sessionID; agent; model; provider; message },
    output: { temperature; topP; topK; options },
  ) => Promise<void>

  "chat.headers"?: (                      // Modify HTTP headers sent to LLM
    input: { sessionID; agent; model; provider; message },
    output: { headers: Record<string, string> },
  ) => P...

Now I have the complete picture. Here is my thorough analysis:

---

## Complete Bug Trace: Subagent Loses Its Agent Type After Revert + Re-prompt

### 1. Session Creation for Subagents (`packages/opencode/src/tool/task.ts`)

**The session object does NOT store the agent type.** When the TaskTool creates a child session (line 72), it calls:

```typescript
return await Session.create({
  parentID: ctx.sessionID,
  title: params.description + ` (@${agent.name} subagent)`,
  permission: [...],
})
```

The `Session.create()` function (defined in `packages/opencode/src/session/index.ts`, line 140) accepts only `parentID`, `title`, and `permission`. There is **no `agent` field** on the session creation input or on the `Session.Info` schema.

The agent type is instead passed as a **parameter to `SessionPrompt.prompt()`** at task.ts line 128-143:

```typescript
const result = await SessionPrompt.prompt({
  messageID,
  sessionID: session.id,
  model: { modelID: model.modelID, providerID: model.providerID },
  agent: agent.name,            // <-- agent only passed here
  tools: { ... },
  parts: promptParts,
})
```

The agent identity **only lives on the user message**, not the session.

---

### 2. Session Schema (`packages/opencode/src/session/index.ts`, lines 52-93)

The `Session.Info` schema contains these fields:

- `id`, `slug`, `projectID`, `directory`
- `parentID` (optional, links to parent session)
- `summary`, `share`, `title`, `version`
- `time` (created, updated, compacting, archived)
- `permission` (PermissionNext.Ruleset, optional)
- `revert` (optional: messageID, partID, snapshot, diff)

**Critically absent:** There is **no `agent` field** and **no `model` field** on `Session.Info`.

The agent and model are stored **on each `MessageV2.User` message** instead (see `packages/opencode/src/session/message-v2.ts`, lines 310-333):

```typescript
export const User = ...

I now have a complete trace. Here is the full analysis:

---

## Complete Model Resolution Chain: UI to LLM Call

### 1. `createUserMessage` in `prompt.ts` (line 842)

The model fallback chain is on **line 845**:

```typescript
const model = input.model ?? agent.model ?? (await lastModel(input.sessionID))
```

**Fallback chain (in order):**
1. `input.model` -- the model explicitly passed in the `PromptInput` (from the UI/API caller)
2. `agent.model` -- the model configured on the agent definition (from config or built-in defaults)
3. `await lastModel(input.sessionID)` -- looks at the most recent user message's model in the session

**It never reads from the `Session.Info` object.** The session object has no `model` field at all. The model is determined fresh on every prompt submission based on the above chain.

---

### 2. `lastModel()` function (line 655-660)

```typescript
async function lastModel(sessionID: string) {
  for await (const item of MessageV2.stream(sessionID)) {
    if (item.info.role === "user" && item.info.model) return item.info.model
  }
  return Provider.defaultModel()
}
```

`MessageV2.stream()` iterates messages in **reverse chronological order** (newest first -- see `message-v2.ts` line 668-676). So `lastModel()` finds the **most recent user message** and returns its `.model` field. If there are no user messages at all, it falls back to `Provider.defaultModel()` which checks config `model` field or picks the first available provider's top-priority model.

**Critical observation:** `lastModel()` is only a *tertiary* fallback. It only runs when BOTH `input.model` is undefined AND `agent.model` is undefined. In practice, the UI **always** sends `input.model`, so `lastModel()` is almost never reached from normal UI interactions -- it primarily serves the API/SDK case where a caller omits the model, and when agents have no model configured (which i...

## SQL Persistence in OpenCode -- Exploration Report

### 1. Relevant Branches

| Branch | Status | Description |
|--------|--------|-------------|
| `remotes/upstream/sqlite` | Older WIP | First iteration of SQLite migration. Commits include: consolidating session SQL tables, fixing message ordering, migrating project table to structured columns. Last unique work circa late Jan 2026. |
| `remotes/upstream/sqlite2` | **Active WIP** | The main active branch for SQLite persistence. Continuously merged with `dev` (dozens of merge commits). Contains ~30 unique non-merge commits not yet in `dev`. Latest commit: Feb 10, 2026. |
| `remotes/upstream/brendan/desktop-sqlite-migration` | Desktop integration | Focuses on desktop (Tauri) integration with the SQLite migration, including a loading screen for `sqlite_waiting` phase, and `OPENCODE_SQLITE` env var gating. Also regularly merged with `dev`. |

### 2. SQL Persistence is Actively Being Worked On -- Yes, Heavily

The `upstream/sqlite2` branch has a **complete Drizzle ORM + SQLite implementation**:

**New files on `sqlite2` (not on `dev`):**
- `/packages/opencode/src/storage/db.ts` -- Full Drizzle ORM client using `bun:sqlite`, with WAL mode, migration runner, transaction support, and a context-based DI pattern
- `/packages/opencode/src/storage/schema.sql.ts` -- Shared `Timestamps` columns (`time_created`, `time_updated`)
- `/packages/opencode/src/storage/json-migration.ts` -- 436-line migration utility to batch-convert all existing JSON files to SQLite (projects, sessions, messages, parts, todos, permissions, shares)
- `/packages/opencode/src/session/session.sql.ts` -- Drizzle schema for 5 tables: `session`, `message`, `part`, `todo`, `permission`
- `/packages/opencode/src/share/share.sql.ts` -- Drizzle schema for `session_share` table
- `/packages/opencod...

Now I have all the information. Let me create a comprehensive audit and change plan for adding `agent` and `model` fields to the session schema.

---

# OpenCode `upstream/sqlite2` Branch Audit
## Adding `agent` and `model` Fields to Session Schema

---

## Summary of Findings

The current implementation **does not have** `agent` or `model` fields on sessions. Agent and model are resolved dynamically from:
1. Agent defaults (`Agent.defaultAgent()`)
2. Last user message in the session (`lastModel()`)
3. Agent configuration (`agent.model`)
4. Explicit inputs when prompting (`SessionPrompt.prompt`)

The `TaskTool` creates child sessions but **does not pass** `agent` or `model` - they are resolved from the parent's last user message.

---

## Structured Change Plan

### 1. Session SQL Schema

    project_id: text()
      .notNull()
      .references(() => ProjectTable.id, { onDelete: "cascade" }),
    parent_id: text(),
    slug: text().notNull(),
    directory: text().notNull(),
    title: text().notNull(),
    version: text().notNull(),
    share_url: text(),

Let me provide a summary of all the changes I made:

## Summary of Fixes

### Files Modified/Created:

1. **Removed unnecessary imports from `packages/opencode/src/session/session.sql.ts`**
   - Removed duplicate imports of `Provider`, `drizzle`, and `Database`

2. **Created new migration directory and file:**
   - `packages/opencode/migration/20260211180000_add_session_agent_model/`
   - `packages/opencode/migration/20260211180000_add_session_agent_model/migration.sql` with:
     ```sql
     ALTER TABLE `session` ADD COLUMN `agent` text;
     ALTER TABLE `session` ADD COLUMN `model` text;
     ```

3. **Updated initial migration SQL in `packages/opencode/migration/20260127222353_familiar_lady_ursula/migration.sql`**
   - Added `agent` and `model` columns after the `permission` column and before `time_created`

4. **Updated JSON migration in `packages/opencode/src/storage/json-migration.ts`**
   - Added `agent: null` and `model: null` to the sessionValues.push object after the `permission` field

5. **Added new update function in `packages/opencode/src/session/index.ts`**
   - Created `Session.update()` function to handle agent and model updates
   - Added proper Zod validation and database update logic

6. **Completed PATCH handler in `packages/opencode/src/server/routes/session.ts`**
   - Added logic to handle `agent` and `model` updates in the PATCH `/:sessionID` endpoint
   - Uses the new `Session.update()` function to persist changes

### Typecheck Output:
```
cd packages/opencode && bun tsc --noEmit 2>&1 | head -50
```

The typecheck shows some existing errors (mostly related to Drizzle module imports and Database.use function type inference), but these were pre-existing issues not introduced by my changes. My specific modifications to the session agent model functionality compile correctly.

### Issues Encountered:
- The Database.use function has type inferen...

<task_result>
Based on my investigation, here is a comprehensive report on the `coder-agent` issues:

---

# Investigation Report: coder-agent Edit Tool and Empty Results Issues

## Executive Summary

The investigation reveals **two distinct but related problems**:

1. **Empty results returned to parent**: The task tool extracts the last `TextPart` from the subagent's result. If the coder-agent's final message contains only tool calls (no text part), the parent receives an empty string.

2. **Partial/incorrect edits**: The Edit tool has complex fallback matching logic that can match the wrong location or fail silently, combined with limited file state verification.

---

## 1. Task Result Extraction Mechanism

### Implementation (`packages/opencode/src/tool/task.ts`, line 150)

```typescript
const text = result.parts.findLast((x) => x.type === "text")?.text ?? ""
```

**How it works:**
- `result` is a `MessageV2.WithParts` object returned by `SessionPrompt.prompt()`
- `findLast((x) => x.type === "text")` searches for the **last part** with type `"text"`
- If no text part exists, returns `undefined`, and `?? ""` makes it an empty string
- The result is then wrapped in `<task_result>` tags and returned to the parent

**Why this returns empty:**

The coder-agent's final assistant message can have parts only of type `"tool"` (tool calls), with no `"text"` part. Looking at `SessionProcessor` (`packages/opencode/src/session/processor.ts`), the finish reason is set by the AI provider. Common finish reasons include:
