+description: "Use when: (1) The user asks to be reminded at a specific time, (2) Schedule recurring notifications, (3) Set up AI-powered scheduled jobs (summarize, review, report), (4) Run custom pipeline scripts on a schedule with voice output. Triggers: remind me, erinnere mich, schedule, cron, daily, weekly, täglich, jeden Montag, crunch, talk at, notify me at, voice reminder."

+
+# crunch-jobs
+
+Schedule voice-notified reminders and AI crunch jobs on NixOS via `systemd` transient timers. When a timer fires, results are spoken aloud through `talk` (ElevenLabs TTS).
+
+No NixOS rebuild needed — jobs are created at runtime via `systemd-run --user` and survive reboots.
+
+## Prerequisites
+
+- `crunch` and `talk` installed (via `m3ta-nixpkgs`)
+- `ELEVENLABS_API_KEY` in environment (or agenix secrets)
+- `loginctl enable-linger <username>` — **critical**: without this, user timers stop when the session ends
+
+**Companion skill:** `voice-notify` covers the `talk` TTS script internals.
+
+## Command Reference
+
+```
+crunch at <time> <message>                    One-shot (14:30 or "2026-07-03 14:30")
+crunch in <duration> <message>                One-shot after delay (30m, 2h, 1h30m)
+crunch daily <time> <message>                 Recurring daily
+crunch weekly <day> <time> <message>          Recurring weekly (Mon or Montag)
+crunch ai <engine> <type> <time> <prompt>     AI crunch (pi|opencode)
+crunch script <type> <time> <script.sh> [args]  Custom script → talk
+crunch list                                    List active jobs
+crunch cancel <name>                           Cancel a job
+crunch purge                                   Remove fired one-shot jobs
+```
+
+## Decision Flow
+
+### 1. What kind of job?
+
+| User intent | Command |
+|---|---|
+| "Erinnere mich an X" (just speak a message) | `crunch <type> <time> <message>` |
+| "Fasse Y zusammen und sag mir Bescheid" (AI processes data) | `crunch ai <engine> <type> <time> <prompt>` |
+| Complex multi-step pipeline (fetch → process → write → speak) | `crunch script <type> <time> <script.sh>` |
+
+### 2. When?
+
+| User says (DE/EN) | Type | Time spec |
+|---|---|---|
+| "in 30 Minuten" / "in 30m" | `in` | `"30m"` |
+| "in 2 Stunden" | `in` | `"2h"` |
+| "um 14:30" | `at` | `"14:30"` |
+| "morgen um 10:00" | `at` | `"10:00"` (fires next 10:00) |
+| "am 3. Juli um 15:00" | `at` | `"2026-07-03 15:00"` |
+| "täglich um 9 Uhr" | `daily` | `"09:00"` |
+| "jeden Montag um 9" | `weekly` | `"Mon 09:00"` |
+| "freitags um 17:00" | `weekly` | `"Fri 17:00"` |
+
+Day names: Mo/Mon/Montag→Mon, Di/Tue→Tue, Mi/Wed→Wed, Do/Thu→Thu, Fr/Fri→Fri, Sa/Sat→Sat, So/Sun→Sun.
+
+### 3. Construct and execute the command.
+
+## Job Types
+
+### Simple Voice Reminders
+
+Just speaks the message at the scheduled time:
+
+```bash
+crunch at "14:30" "Müll rausbringen"
+crunch in "30m" "Build ist fertig — Ergebnis checken"
+crunch daily "09:00" "Guten Morgen! Tagesplanung:"
+crunch weekly "Fri 16:00" "Weekly Review nicht vergessen"
+```
+
+### AI Crunch Jobs
+
+Runs a prompt through `pi` or `opencode` in print mode (non-interactive). Agent processes data, stdout → `talk`:
+
+```bash
+crunch ai pi in "2h" "Lies die neuesten Git-Commits und gib eine 3-Satz Zusammenfassung"
+crunch ai opencode daily "07:30" "Check die PostgreSQL-Logs auf Errors der letzten 24h"
+crunch ai pi weekly "Mon 09:00" "Generiere Weekly Summary aus git log"
+```
+
+The agent has full file-system access. It can call CLI tools, write files, and chain operations. Only the final stdout becomes the voice message.
+
+### Custom Script Jobs
+
+Runs any shell script on schedule. Script stdout → `talk`. Empty stdout = silence (no error).
+
+```bash
+crunch script daily "08:00" ~/scripts/basecamp-daily.sh
+crunch script weekly "Mon 09:00" ~/scripts/weekly-report.sh arg1 arg2
+```
+
+Example script — fetches data, AI summarizes, writes report, speaks summary:
+
+```bash
+#!/usr/bin/env bash
+# ~/scripts/basecamp-daily.sh
+TODOS=$(basecamp todos --today 2>/dev/null) || exit 0
+echo "$TODOS" | pi -p "Erstelle strukturierte Summary, speichere als ~/reports/daily.md. Antworte mit Top 3 Prioritäten."
+```
+
+## After Scheduling
+
+- crunch outputs `✓ Scheduled: crunch-<name>-<random>`
+- Share the job name with the user (needed for cancel)
+- List: `crunch list`
+- Cancel: `crunch cancel <name>`
+
+## Examples
+
+```
+User: "Erinnere mich in 30 Minuten daran, den Build zu checken"
+→ crunch in "30m" "Build checken"
+
+User: "Jeden Morgen um 8 will ich meine Basecamp Todos hören"
+→ crunch ai pi daily "08:00" "Hole heutige Todos aus Basecamp, antworte mit Top 3 Prioritäten"
+
+User: "Freitags um 16 Uhr will ich ein Weekly Report als Voice"
+→ crunch script weekly "Fri 16:00" ~/scripts/weekly-report.sh
+```
+
+## Pitfalls
+
+- **Lingering**: Without `loginctl enable-linger <user>`, user systemd timers STOP when the session ends. Verify: `loginctl show-user <username> | grep Linger`
+- **No session on servers**: `systemd-run --user` needs an active user session. On headless servers, use system-level timers or Hermes cron instead.
+- **Quote messages**: Always quote the message/prompt argument (spaces, special chars).
+- **Date format**: Specific dates must be `YYYY-MM-DD` for `crunch at`.
+- **Voice toggle**: `VOICE_NOTIFY=0` silences all talk output globally.

+- **Cancel button doesn't stop audio?** Fixed: the poll loop now uses `[ -s ]` (non-empty check) instead of `[ -f ]` (exists). The action file is created as empty by the shell redirect; it's only filled when the user clicks Abbrechen.
