How to run

Step 1: Prepare CSV

Claude prepares CSV with recipients. Minimum columns:

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)

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

Or with a template:

python3 $TG_TOOLS_PATH/tools/tg_send.py \
    --input contacts.csv --message "Hello, {name}! Text." --dry-run

Step 3: Send

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):

{"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`
