# Beam Debug Issue Tasks

**Debug failed Beam.ai tasks using Langfuse traces.**

## When to Use

- Diagnose why a task failed, stopped, or needs input
- Find root cause from Langfuse trace reasoning
- Generate debug reports for documentation or handoff

---

## Prerequisites

`.env` file at project root:

```
# Beam.ai - BID instance
BEAM_API_KEY=your_bid_api_key
BEAM_WORKSPACE_ID=your_bid_workspace_id

# Beam.ai - Prod instance
BEAM_API_KEY_PROD=your_prod_api_key
BEAM_WORKSPACE_ID_PROD=your_prod_workspace_id

# Langfuse (self-hosted)
LANGFUSE_PUBLIC_KEY=pk-lf-...
LANGFUSE_SECRET_KEY=sk-lf-...
LANGFUSE_HOST=https://tracing.beamstudio.ai
```

**Dependencies**: `pip install requests python-dotenv`

---

## Quick Start

```bash
# List issue tasks (default: last 1 day, BID workspace)
python 03-skills/beam-debug-issue-tasks/scripts/debug_issue_tasks.py <agent_id>

# Debug specific task with full trace analysis
python 03-skills/beam-debug-issue-tasks/scripts/debug_issue_tasks.py <agent_id> --task-id <task_id>

# Use prod workspace
python 03-skills/beam-debug-issue-tasks/scripts/debug_issue_tasks.py <agent_id> --workspace prod
```

---

## Workspaces

| Workspace | API Endpoint | Langfuse Project |
|-----------|--------------|------------------|
| `bid` (default) | api.bid.beamstudio.ai | cmauxbgww000582ry4644c2qr |
| `prod` | api.beamstudio.ai | clw5gbhuy0003u3rv4jzzoesh |

---

## Issue Statuses

Tasks are flagged as "issue" if status is:
- `FAILED` - Execution failed
- `ERROR` - Processing error
- `STOPPED` - Condition failed
- `CANCELLED` - User cancelled
- `TIMEOUT` - Execution timeout
- `USER_INPUT_REQUIRED` - Missing input data

---

## Debug Reports

Reports saved to: `04-workspace/agents/{agent_name}/debug/`

**Format**: Smart Brevity (headline, takeaway, why it matters, details, fix)

**Key spans analyzed**:
- `ParameterSelection/v2` - How parameters were matched
- `ExecuteGPT_Tool/v1` - Tool execution reasoning
- `NodeSelection:EdgeEvaluation/v1` - Routing decisions
- `TaskSuccessCriteriaCheck/v1` - Why task stopped

---

## CLI Reference

| Flag | Description | Default |
|------|-------------|---------|
| `agent_id` | Beam agent ID (required) | - |
| `--workspace`, `-w` | Workspace: bid or prod | bid |
| `--days`, `-d` | Look back period (1, 3, 7, 14, 30) | 1 |
| `--task-id`, `-t` | Debug specific task ID | - |
| `--summary`, `-s` | Show grouped summary | false |
| `--limit`, `-l` | Max tasks to show | 10 |
| `--output`, `-o` | Save to JSON file | - |
| `--no-trace` | Skip Langfuse lookup | false |

---

## Example Output

### Debug Report (Smart Brevity)

```markdown
# Task stopped: condition failed

Checklist evaluation: subfolder must equal 'Schreiben Schuldner' but was null.

**Why it matters**: This task did not complete successfully and may need attention.

**The details**:
- **Status**: `STOPPED`
- **Task**: `ab3cbbb8-28da-41aa-b726-25931d14d7d4`
- **Latency**: 159.6s
- **Cost**: $0.1043

**Key spans**:
- NodeSelection:EdgeEvaluation/v1 (23.4s)
- TaskSuccessCriteriaCheck/v1 (7.2s)

**Root cause**:
> The criterion is not met because subfolder is not set to required value.

**Fix**: Review the condition that stopped execution. Check if input data meets requirements.
```

## Langfuse Links

Each report includes direct links:
- **Session URL**: All traces for the task
- **Trace URL**: Specific execution with full details

---

## Error Handling

| Error | Solution |
|-------|----------|
| `BEAM_API_KEY not found` | Add to .env |
| `Invalid workspace` | Check workspace parameter (bid/prod) |
| `No traces found` | Verify agent has Langfuse integration |
| `401 Unauthorized` | Verify API keys |
