Implement cron job management system for scheduled tasks (similar to OpenAI's Pulse but the AI can also schedule jobs)
- Introduced a new cron job system allowing users to schedule automated tasks via the CLI, supporting one-time reminders and recurring jobs.
- Added commands for managing cron jobs: `/cron` to list jobs, `/cron add` to create new jobs, and `/cron remove` to delete jobs.
- Implemented job storage in `~/.hermes/cron/jobs.json` with output saved to `~/.hermes/cron/output/{job_id}/{timestamp}.md`.
- Enhanced the CLI and README documentation to include detailed usage instructions and examples for cron job management.
- Integrated cron job tools into the hermes-cli toolset, ensuring they are only available in interactive CLI mode.
- Added support for cron expression parsing with the `croniter` package, enabling flexible scheduling options.

## Scheduled Tasks (Cron Jobs)
|
||||
|
||||
Hermes Agent can schedule automated tasks to run in the future - either one-time reminders or recurring jobs.
|
||||
|
||||
### CLI Commands
|
||||
|
||||
```bash
|
||||
# List scheduled jobs
|
||||
/cron
|
||||
|
||||
# Add a one-shot reminder (runs once in 30 minutes)
|
||||
/cron add 30m Remind me to check the build status
|
||||
|
||||
# Add a recurring job (every 2 hours)
|
||||
/cron add "every 2h" Check server status at 192.168.1.100 and report any issues
|
||||
|
||||
# Add a cron expression (daily at 9am)
|
||||
/cron add "0 9 * * *" Generate a morning briefing summarizing GitHub notifications
|
||||
|
||||
# Remove a job
|
||||
/cron remove abc123def456
|
||||
```
|
||||
|
||||
### Agent Self-Scheduling
|
||||
|
||||
The agent can also schedule its own follow-up tasks using tools:
|
||||
|
||||
```python
|
||||
# Available when using hermes-cli toolset (default for CLI)
|
||||
schedule_cronjob(prompt="...", schedule="30m", repeat=1) # One-shot
|
||||
schedule_cronjob(prompt="...", schedule="every 2h") # Recurring
|
||||
list_cronjobs() # View all jobs
|
||||
remove_cronjob(job_id="...") # Cancel a job
|
||||
```
|
||||
|
||||
**⚠️ Important:** Cronjobs run in **isolated sessions with NO prior context**. The prompt must be completely self-contained with all necessary information (file paths, URLs, server addresses, etc.). The future agent will not remember anything from the current conversation.
|
||||
|
||||
### Schedule Formats
|
||||
|
||||
| Format | Example | Description |
|
||||
|--------|---------|-------------|
|
||||
| Duration | `30m`, `2h`, `1d` | One-shot delay from now |
|
||||
| Interval | `every 30m`, `every 2h` | Recurring at fixed intervals |
|
||||
| Cron | `0 9 * * *` | Cron expression (requires `croniter`) |
|
||||
| Timestamp | `2026-02-03T14:00` | One-shot at specific time |
|
||||
|
||||
### Repeat Options
|
||||
|
||||
| repeat | Behavior |
|
||||
|--------|----------|
|
||||
| (omitted) | One-shot schedules run once; intervals/cron run forever |
|
||||
| `1` | Run once then auto-delete |
|
||||
| `N` | Run N times then auto-delete |
|
||||
|
||||
### Running the Cron Daemon
|
||||
|
||||
Jobs are stored in `~/.hermes/cron/jobs.json` and executed by a scheduler:
|
||||
|
||||
```bash
|
||||
# Option 1: Built-in daemon (checks every 60 seconds)
|
||||
python cli.py --cron-daemon
|
||||
|
||||
# Option 2: System cron integration (run once per minute)
|
||||
# Add to crontab: crontab -e
|
||||
*/1 * * * * cd ~/hermes-agent && python cli.py --cron-tick-once >> ~/.hermes/cron/cron.log 2>&1
|
||||
```
|
||||
|
||||
### Job Output
|
||||
|
||||
Job outputs are saved to `~/.hermes/cron/output/{job_id}/{timestamp}.md` for review.
|
||||
|
||||

## 11. Scheduled Tasks / Cron Jobs ⏰
|
||||
## 11. Scheduled Tasks / Cron Jobs ⏰ ✅ COMPLETE
|
||||
|
||||
**Problem:** Agent only runs on-demand. Some tasks benefit from scheduled execution (daily summaries, monitoring, reminders).
|
||||
|
||||
**Ideas:**
|
||||
- [ ] **Cron-style scheduler** - Run agent turns on a schedule
|
||||
- Store jobs in `~/.hermes/cron/jobs.json`
|
||||
- Each job: `{ id, schedule, prompt, session_mode, delivery }`
|
||||
- Uses APScheduler or similar Python library
|
||||
**Solution Implemented:**
|
||||
|
||||
- [x] **Cron-style scheduler** - Run agent turns on a schedule
|
||||
- Jobs stored in `~/.hermes/cron/jobs.json`
|
||||
- Each job: `{ id, name, prompt, schedule, repeat, enabled, next_run_at, ... }`
|
||||
- Built-in scheduler daemon or system cron integration
|
||||
|
||||
- [ ] **Session modes:**
|
||||
- `isolated` - Fresh session each run (no history, clean context)
|
||||
- `main` - Append to main session (agent remembers previous scheduled runs)
|
||||
- [x] **Schedule formats:**
|
||||
- Duration: `30m`, `2h`, `1d` (one-shot delay)
|
||||
- Interval: `every 30m`, `every 2h` (recurring)
|
||||
- Cron expression: `0 9 * * *` (requires `croniter` package)
|
||||
- ISO timestamp: `2026-02-03T14:00:00` (one-shot at specific time)
|
||||
|
||||
- [x] **Repeat options:**
|
||||
- `repeat=None` (or omit): One-shot schedules run once; intervals/cron run forever
|
||||
- `repeat=1`: Run once then auto-delete
|
||||
- `repeat=N`: Run exactly N times then auto-delete
|
||||
|
||||
- [ ] **Delivery options:**
|
||||
- Write output to file (`~/.hermes/cron/output/{job_id}/{timestamp}.md`)
|
||||
- Send to messaging channel (if integrations enabled)
|
||||
- Both
|
||||
|
||||
- [ ] **CLI interface:**
|
||||

|

python cli.py --cron remove <job_id>
|

/cron remove <job_id>
|
||||
```
|
||||
|
||||
- [ ] **Agent self-scheduling** - Let the agent create its own cron jobs
|
||||
- New tool: `schedule_task(prompt, schedule, session_mode)`
|
||||
- "Remind me to check the deployment tomorrow at 9am"
|
||||
- Agent can set follow-up tasks for itself
|
||||
- [x] **Agent self-scheduling tools** (hermes-cli toolset):
|
||||
- `schedule_cronjob(prompt, schedule, name?, repeat?)` - Create a scheduled task
|
||||
- `list_cronjobs()` - View all scheduled jobs
|
||||
- `remove_cronjob(job_id)` - Cancel a job
|
||||
- Tool descriptions emphasize: **cronjobs run in isolated sessions with NO context**
|
||||
|
||||
- [ ] **In-chat command:** `/cronjob {prompt} {frequency}` when using messaging integrations
|
||||
- [x] **Daemon modes:**
|
||||
```bash
|
||||
# Built-in daemon (checks every 60 seconds)
|
||||
python cli.py --cron-daemon
|
||||
|
||||
# Single tick for system cron integration
|
||||
python cli.py --cron-tick-once
|
||||
```
|
||||
|
||||
**Files to create:** `cron/scheduler.py`, `cron/jobs.py`, `tools/schedule_tool.py`

- [x] **Output storage:** `~/.hermes/cron/output/{job_id}/{timestamp}.md`

||||
**Files created:** `cron/__init__.py`, `cron/jobs.py`, `cron/scheduler.py`, `tools/cronjob_tools.py`
