The custom RRULE panel covers most patterns but can't express "every
weekday at 9, 12, and 18" or "every 15 minutes within working hours"
in a single rule. RRULE's BYxxx fields can technically combine, but
the picker UX gets unwieldy fast. Cron expressions cover everything
in one line.
Storage / dispatch
- Cron rules live in the same `reminders.rrule` column with a sentinel
prefix: `CRON:0 9 * * 1-5`. No schema change.
- `@cmbot/shared` now exports:
CRON_PREFIX, isCronRule, stripCronPrefix, validateCronExpression
- `nextOccurrence(rule, tz, after)` and `validateMinInterval(rule, tz)`
detect the prefix and dispatch to `cron-parser`; non-cron rules
continue to flow through rrule unchanged.
- `cron-parser@^5.5.0` added as an explicit dep on @cmbot/shared
(it was already transitively present via pg-boss).
Server actions
- `createReminderAction` / `updateReminderAction`: when rrule has the
CRON: prefix, the user's date+time inputs are ignored — the action
validates the cron, runs the min-interval check (5 min between
fires), and computes scheduledAt as the next match of the cron
expression after now. The bot's existing fire-reminder loop
re-arms via `nextOccurrence` after each fire, which already speaks
cron via the dispatch above.
Picker
- New "Cron expression…" preset at the bottom of the radio list:
"Full sec/min/hour/day/month/dow combinational power"
Selecting it reveals a CronPanel:
* font-mono cron input (5- or 6-field accepted)
* inline examples: 0 9 * * 1-5, */15 * * * *, 0 9,12,18 * * *,
0 0 1 * *
* note that the Date+Time controls above are ignored once a cron
expression is set
- RecurrenceSpec gains an optional `cron` string and a new `kind: "cron"`.
- buildRrule emits `CRON:<expr>` for cron specs.
- specFromRrule round-trips a CRON-prefixed rule back into the spec.
- describeRecurrence renders "Cron: <expr>" so the list view and
review steps show the expression.
Tests (+10; 17 shared + 26 bot + 138 web = 181 total)
- packages/shared rrule.test.ts (+8):
* CRON_PREFIX / isCronRule / stripCronPrefix
* nextOccurrence on a CRON rule returns the right next match in the
operator timezone (e.g. weekday 9 AM KL ↔ exact UTC instant)
* RRULE rules still flow through unchanged
* validateMinInterval on cron: hourly OK, every-minute rejected,
malformed string returns a useful error
* validateCronExpression positive + negative cases
- recurrence.test.ts (+5): cron preset round-trip, label assertions,
`buildRrule`/`specFromRrule` for cron specs.

cm WhatsApp Reminder Bot
Self-hosted WhatsApp reminder bot. Pairs multiple WhatsApp accounts via Telegram-delivered QR codes and sends scheduled reminders to groups.
Status
Plan 1 complete. Foundation, DB schema, and Telegram-driven WhatsApp pairing are working end-to-end. Reminder scheduling, the web dashboard, and production deploy are upcoming plans (docs/superpowers/plans/).
What's working today:
- Single-operator Telegram bot with a whitelist + audit log of every command.
- BotFather-style menu navigation:
/menuopens a single message that edits in place as you navigate. - Pair a new WhatsApp account with
/menu→ 📡 Pair New → reply with a label. QR is delivered to Telegram and refreshed in place as it expires. - Browse paired accounts with 📒 Accounts. Tap an account → see groups, send a test text message, or unpair.
- Group sync runs at pairing and on every Baileys
groups.upsert/groups.updateevent, plus a manual 🔄 Refresh button. Removed groups are pruned automatically. - Auto-reconnect on transient drops; restart-survival via Baileys
useMultiFileAuthState(no QR rescan needed across container restarts as long as WhatsApp hasn't logged the device out).
Host requirements
Only Docker. No host Node, pnpm, or any other language toolchain — everything runs in containers via the long-lived tools service.
Architecture in one paragraph
Two app containers and one external dependency. bot (Node.js) holds the live Baileys WhatsApp sessions, the grammy Telegram bot, and (in plan 2) a pg-boss scheduler. web (Next.js, plan 3) is stateless UI + API. tools is a long-running Node 22 + pnpm sidecar used for installs/tests/typechecks/migrations so the host doesn't need a Node toolchain. Postgres lives external at 192.168.0.210 in a wabot database. All cross-service communication goes through Postgres (LISTEN/NOTIFY for events, table writes for state).
Full design spec: docs/superpowers/specs/2026-05-03-whatsapp-bot-design.md
Quick start (dev)
Prerequisites: Docker, the wabot database + waBot role on 192.168.0.210 (with a pg_hba.conf line permitting 192.168.0.0/24), and a Telegram bot token from @BotFather.
# 1. Configure env
cp envs/.env.example .env.development
# edit .env.development: real DATABASE_URL, TELEGRAM_BOT_TOKEN, your TG user ID
scripts/gen_auth_secret.sh --write
# 2. Bring up the tools container, install deps
NO_SUDO=1 scripts/dev.sh up
NO_SUDO=1 scripts/dev.sh pnpm install
# 3. Apply migrations and seed your operator row
NO_SUDO=1 scripts/db.sh migrate
NO_SUDO=1 scripts/db.sh seed
# 4. Watch the bot service
NO_SUDO=1 scripts/dev.sh logs bot
In Telegram, message your dev bot /menu, tap 📡 Pair New, reply with a label, scan the QR.
NO_SUDO=1 is the right setting if your user is in the docker group (the default for this repo). Drop it if you need sudo docker.

Scripts
All pnpm/tsx/drizzle-kit invocations run inside the tools container, so no host Node is needed.
