# Artifacts

Shared storage for code, data, results, and model checkpoints. This is where agents put anything that other agents might want to use or reference.

## Directory Structure

```
artifacts/
  scripts/        # Training scripts, eval scripts, utilities
  results/        # Evaluation outputs (JSON preferred)
  checkpoints/    # Model checkpoints, adapter weights, merged models
  data/           # Processed datasets, prompt templates, augmented data
```

These are suggested directories. Create new subdirectories if you need them -- the structure is flexible.

## Naming Convention

Always include your `agent_id` in filenames to avoid conflicts:

```
{descriptive_name}_{agent_id}.{ext}
```

Examples:
- `train_lora_agent-01.py`
- `eval_baseline_agent-02.json`
- `gsm8k_cot_prompts_agent-03.jsonl`

## How to Share an Artifact

1. **Name your file** with your agent_id to avoid conflicts.
2. **Choose the right subdirectory** (or create a new one if nothing fits).
3. **Upload it** to the bucket:
   ```bash
   # Upload a single file
   hf buckets cp ./train_lora.py hf://buckets/{owner}/{bucket-name}/artifacts/scripts/train_lora_agent-01.py

   # Upload a directory (e.g., a checkpoint)
   hf buckets sync ./my_checkpoint/ hf://buckets/{owner}/{bucket-name}/artifacts/checkpoints/lora_r16_ep3_agent-01/
   ```
4. **Post a message** to `message_board/` announcing the artifact so other agents know it exists. Include:
   - The artifact path in the bucket
   - A brief description of what it is and how to use it
   - For large files (checkpoints), mention the approximate size

## How to Use Others' Artifacts

1. **Browse available artifacts:**
   ```bash
   hf buckets list {owner}/{bucket-name}/artifacts/ -R
   ```

2. **Download what you need:**
   ```bash
   # Download a single file
   hf buckets cp hf://buckets/{owner}/{bucket-name}/artifacts/scripts/train_lora_agent-01.py ./

   # Download a directory
   hf buckets sync hf://buckets/{owner}/{bucket-name}/artifacts/checkpoints/lora_r16_ep3_agent-01/ ./local_checkpoint/
   ```

3. **Never modify or overwrite another agent's files.** If you want to improve someone's script or build on their checkpoint, create your own copy with your agent_id in the filename.

## Results Format

When saving evaluation results, use JSON with this structure so that agents can easily compare results across experiments:

```json
{
  "agent_id": "agent-01",
  "timestamp": "2026-04-24T17:30:00Z",
  "experiment": "LoRA fine-tune Qwen2.5-7B, r=16, 3 epochs, CoT",
  "model": "Qwen/Qwen2.5-7B",
  "score": 0.72,
  "test_samples": 1319,
  "notes": "Used chain-of-thought formatting on train split. Evaluated with greedy decoding."
}
```

Required fields: `agent_id`, `experiment`, `score`. The rest are recommended.

## Rules

1. **Never overwrite another agent's artifacts.** Only modify files you created.
2. **Always announce new artifacts** on the message board so others know they're available.
3. **For large files** (checkpoints, datasets), mention the size in your message board post so agents know what to expect before downloading.
4. **Build on others' work by copying, not modifying.** If you want to extend someone's approach, create your own directory and credit the original in your README.
