## Paths

| What | Path |
|------|------|
| Tool | `$TG_TOOLS_PATH/tools/tg_send.py` |
| Shared lib | `$TG_TOOLS_PATH/tg_utils/` |
| Telegram Session | `$SALES_PATH/telegram/sessions/telegram_session.session` |
| ENV | `$SALES_PATH/.env` |
| Send Log | `$TG_TOOLS_PATH/data/send_log.json` |

## How to run

### Step 1: Prepare CSV

Claude prepares CSV with recipients. Minimum columns:

```csv
key,name,phone,username,message
p-001,Alice,+380XXXXXXXXX,,Hello Alice! Message text.
p-002,Ruslan,,,Nizami_ua,Hello Ruslan!
```

Or without the `message` column -- then use the `--message` template.

### Step 2: Dry-run (verification)

```bash
python3 $TG_TOOLS_PATH/tools/tg_send.py \
    --input contacts.csv --dry-run
```

Or with a template:
```bash
python3 $TG_TOOLS_PATH/tools/tg_send.py \
    --input contacts.csv --message "Hello, {name}! Text." --dry-run
```

### Step 3: Send

```bash
python3 $TG_TOOLS_PATH/tools/tg_send.py \
    --input contacts.csv --send

# Or test on the first contact:
python3 $TG_TOOLS_PATH/tools/tg_send.py \
    --input contacts.csv --send --test 1
```

## Architecture

**Claude (LLM) is responsible for:** selecting recipients, composing text, generating CSV, interpreting results, updating CRM.

**tg-send is responsible for:** Telegram session, phone normalization, message delivery, rate limiting, idempotency, flood handling.

### Shared library (`tg_utils/`)

| Module | Purpose |
|--------|---------|
| `auth.py` | Connecting to Telegram, loading credentials |
| `phone.py` | Phone normalization (UA/PL/IE/US) |
| `rate_limit.py` | Delays, batch pauses, flood cooldown |
| `send_log.py` | Send log (idempotency) |
| `contacts.py` | Entity resolution (username/phone), ImportContactsRequest |
| `output.py` | JSON-line output for composition |

## Rate Limiting

| Mode | Delay | Limit/day | Batch pause |
|------|-------|-----------|-------------|
| Warm (default) | 20-60s | 35 | - |
| Cold (`--cold`) | 30-60s | 5 | 30min every 3 |

## Output

Stdout: JSON lines (for pipe/composition):
```json
{"event":"send","status":"ok","key":"p-001","target":"@user","name":"Alice","ts":"..."}
{"event":"summary","sent":5,"failed":1,"skipped":2,"ts":"..."}
```

Stderr: human-readable progress.

## Limitations

- Not all phone numbers are registered on Telegram
- Privacy settings can block (UserPrivacyRestrictedError)
- FloodWaitError = 24h cooldown, PeerFloodError = 48h cooldown
- Temporary contacts are automatically removed after sending

## Troubleshooting

| Problem | Solution |
|---------|----------|
| FloodWaitError | Automatic 24h cooldown. `--reset-cooldown` to reset |
| PeerFloodError | 48h cooldown. Wait or `--reset-cooldown` |
| SessionExpired | `telegram-session` |
| UserPrivacyRestrictedError | Person has blocked DMs |
| "Not authorized" | Need QR login via `tg-auth` |
