| **Daily** | Automated 4-system horoscope via cron | Cron schedule |
| **On-demand** | Instant horoscope | "my horoscope", "horoscope now" |

| **Manage** | Pause/resume/change time | "pause horoscope", "change horoscope time" |

```

## Setup Mode

1. Ask for: **birth date** (YYYY-MM-DD), **birth time** (HH:MM), **birth city** (lat/lon + timezone)
2. Ask for: **Telegram chat ID**, **preferred delivery time** + **timezone**
3. Run all calculation scripts: natal chart, Ba-Zi, numerology
4. Write results to `~/clawd/memory/horoscope-users.md` (include lat/lon, LifePath number)
5. Create daily cron job
6. Confirm: Western sign + ASC + Ba-Zi Day Master + LifePath + delivery schedule

## Daily Mode

Cron triggers 4 scripts → all JSON fed to LLM → compose multi-system horoscope → Telegram.

See `references/horoscope-prompt-template.md` for full agentTurn message.

## On-Demand Mode

Trigger: "my horoscope", "horoscope now", "what's my horoscope today"

Same flow, inline (not isolated session). Includes daily I Ching hexagram.

## I Ching Mode

Trigger: "cast I Ching", "throw hexagram", "que Kinh Dich"

- **Random cast:** 3-coin method, cryptographic randomness
- **Manual input:** User provides upper/lower trigrams + moving lines
- Output: primary hexagram, moving lines, transformed hexagram, SPARK summary

## Management Commands

| Command | Action |
|---------|--------|
| "pause horoscope" | Disable cron job |
| "resume horoscope" | Enable cron job |
| "change horoscope time to 7am" | Update cron schedule |
| "remove horoscope" | Delete cron job + memory entry |

## Cron Delivery

One cron job per user: `horoscope-daily-{username}`

```json
{
  "name": "horoscope-daily-{username}",
  "enabled": true,
  "schedule": { "kind": "cron", "expr": "0 {hour} * * *", "tz": "{timezone}" },
  "sessionTarget": "isolated",
  "payload": {
    "kind": "agentTurn",
    "message": "[prompt from references/horoscope-prompt-template.md]",
    "model": "claude-sonnet-4-20250514",
    "timeoutSeconds": 180,
    "deliver": true,
    "channel": "telegram",
    "to": "{telegram_chat_id}"
  },
  "isolation": { "postToMainPrefix": "Horoscope delivered", "postToMainMode": "summary" }
}
```

## State Tracking

File: `state/users.json` — maps usernames to cron job IDs.

## Error Handling

- **kerykeion fails:** Fallback to `fetch-planetary-positions.py` (API-based, no houses)
- **API down:** LLM generates horoscope from zodiac knowledge only
- **Memory missing:** Prompt user to run setup first
- **I Ching data missing:** Generate hexagram from embedded trigram math only
