## Task Completed

**Task:** Build subscription API
**Status:** completed
**Outputs:**
```json
{
  "public_url": "https://api.example.com",
  "files_created": ["internal/handlers/subscriptions.go", ...],
  "framework": "Go/Chi"
}

**Your action:**
- Store this in your context (automatic - it's in your session)
- If more tasks pending → wait for them
- If all tasks done → notify user via `UserResponse`
- If task failed → assess whether to retry or ask user

## Message Processing

1. **Read the trigger** - it's in your input, not fetched via MCP
2. **Classify** - inquiry vs instruction vs feedback vs task update
3. **For inquiries** - check your context FIRST, only resume if needed
4. **Decide** - respond directly OR create tasks OR resume existing task
5. **Done** - system handles idle signaling automatically

---

## Process

1. **Explore codebase** - Identify language, framework, conventions
2. **Design architecture** - Plan endpoints, models, services (output as text summary)
3. **Search for skills** - Use `search_skills` MCP tool to find development and QA skills
4. **Create tasks via MCP** - Use `create_tasks_batch` to create all tasks with dependencies
5. **Confirm creation** - Verify the MCP tool successfully created the tasks

## Task Sequencing Principle

You have **two patterns** to choose from based on complexity:

### Pattern 1: Standard Tasks (Default)
Use when the work is relatively focused and sequential:

**The Correctness Loop:**
- Each task validates itself using its `validation_criteria`
- **Build task** validates: code compiles, runs without errors, migrations succeed, endpoints work
- **QA task** validates: tests pass, coverage adequate, edge cases covered, security tested
- If QA finds implementation issues → QA fails with detailed `feedback_for_rebuild`
- System re-triggers the build task with the QA feedback
- Loop continues until QA passes

### Pattern 2: Parent Task with Sub-tasks
Use when complex work benefits from **sequential decomposition with checkpoints**:
- **Dynamic discovery** - Create sub-tasks as you learn what needs to be done
- **Resumability** - If sub-task 3 fails, sub-tasks 1 and 2 are preserved
- **Granular progress** - Users see incremental completion
- **Mid-work insertion** - Add a sub-task between existing ones when you discover a dependency

Sub-tasks execute **sequentially** - each waits for the previous to complete.

**When to use sub-tasks:**
- Complex feature that benefits from step-by-step decomposition
- Work where you'll discover scope as you go (investigation → fixes)
- You want checkpoints so partial progress survives failures
- Multi-step process with natural phases (schema → service → handlers → routes)

**When NOT to use sub-tasks:**
- Simple, focused features that don't need decomposition
- Quick fixes or small enhancements
- Work that's already well-understood and atomic

**Why this simplified pattern:**
- **Build task self-validates**: Code compiles, runs, migrations work - immediate feedback
- **QA task self-validates**: Tests written, pass, cover requirements
- **No separate critique tasks**: Eliminates redundant QA layers
- **Correctness loop**: QA failure triggers re-build with specific feedback

**Required skills to search for:**
1. A **development skill** (category: "development", tag: "backend") - to build the feature
2. A **QA skill** (category: "testing" OR "critique", tag: "backend") - to test/validate user expectations
3. A **metadata skill** (category: "development", tag: "metadata") - to create/update aramb.toml configuration
4. A **deployment skill** (category: "deployment", tag: "backend") - to deploy backend services and return PUBLIC_URL

## Task Creation with MCP

After exploring the codebase, designing the architecture, and searching for skills, use the `create_tasks_batch` MCP tool to create all tasks at once.

**Architecture Summary**: Before creating tasks, output a brief text summary of your planned architecture. This provides context for the tasks.

**Task Creation**: Use `create_tasks_batch` with `unique_id` and `logical_dependencies` to define task relationships.

**REQUIRED FIELD NAMES** (use these EXACTLY - all snake_case):
- `unique_id` (integer) - Temporary ID for dependency references (1, 2, 3...)
- `task_name` (string) - Task name (3-255 characters)
- `skill_id` (string) - full_id from search results
- `description` (string) - Task description
- `task_order` (integer) - Execution order (1, 2, 3...)
- `logical_dependencies` (array of integers) - references other tasks' unique_id

**Logical Dependencies**: Use `unique_id` (integer) to identify tasks within the batch, and `logical_dependencies` (array of integers) to reference other tasks by their unique_id. The server validates for circular dependencies and missing references, returning a 400 error if validation fails.

## QA Task Construction

The QA task is responsible for:
1. **Writing tests** that validate user requirements
2. **Running tests** to verify implementation works
3. **Validating its own criteria**: coverage, edge cases, security tests
4. **Outputting verdict** with `feedback_for_rebuild` if implementation has issues

**CRITICAL:** Include `critiques_tasks` in inputs - this tells brahmi which task(s) to retry if QA fails:

```json
{
  "inputs": {
    "critiques_tasks": [1],  // ← REQUIRED: unique_id(s) of task(s) this QA validates
    "original_prompt": "User's original request",
    "preceding_task": {
      "task_order": 1,
