Add three new sections to all 14 examples: - "Carry Forward": what output feeds into later examples (01-10) - "The Cumulative Path": alternative prompt building on previous output (02-10) - "Now Try It Yourself": personalized template with transferable pattern (all) - "Building On" callout connecting back to previous examples (02-10) Add Example 14: Build Your Personal Agent - capstone that guides reader through writing their own CLAUDE.md, creating a personal skill, connecting a messaging channel, setting up automation, and testing end-to-end. Update README with cumulative path diagram, two usage modes, and example 14. Update GETTING-STARTED.md with cross-references to relevant examples. 17 files changed, 703+ lines added. The examples now form a coherent learning path from "see what it can do" to "build your own agent." Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# Example 08: Cron and Scheduled Automation
|
|
|
|
**Capability:** Claude Code supports scheduled and automated execution through
|
|
three complementary mechanisms, covering in-session polling through to
|
|
system-level cron jobs.
|
|
|
|
**OpenClaw equivalent:** HEARTBEAT.md, cron scheduler, webhooks, auto-reply.
|
|
|
|
> **Building on Examples 01-07.** You have a complete pipeline: research (01-03), memory (05), agent review (06), and delivery (07). This example makes it run without you pressing enter. Automation is what separates a demo from a daily driver.
|

|
|
## Three Approaches
|
|
|
|
### Approach 1: /loop (In-session polling, v2.1.71)
|
|
|
|
For tasks that should repeat while Claude Code is running:
|
|
|
|
```
|
|
/loop interval=60
|
|
|
|
Every 60 seconds, check if a file called 'trigger.txt' exists in this
|
|
directory. If it does, read its contents, execute the task described inside,
|
|
delete the file, and write the result to 'loop-output.md'. Then wait for
|
|
the next trigger.
|
|
```
|
|
|
|
Use this for development and testing. The loop runs as long as the session
|
|
is active.
|
|
|

|
|
|
|
### Approach 2: CronCreate (System-level scheduling, v2.1.71)
|
|
|
|
For tasks that should run on a schedule even when Claude Code is not open:
|
|
|
|
```
|
|
Create a cron job that runs the 'daily-briefing' skill every morning at 07:00.
|
|
Use the automation/daily-briefing.sh wrapper script. Show me the cron entry
|
|
before creating it so I can verify it.
|
|
```
|
|
|
|
Claude Code calls `CronCreate` to register the job with the system cron daemon.
|
|
Use `CronList` to see all registered jobs and `CronDelete` to remove them.
|
|
The `automation/daily-briefing.sh` script in this repo is a ready-made wrapper.
|
|
|

|
|
|
|
### Approach 3: /schedule (Remote trigger, web only)
|
|
|
|
For triggering runs from anywhere, including from a phone:
|
|
|
|
```
|
|
/schedule "Run the web-research skill on 'latest Anthropic news' and
|
|
email me a summary" at 2025-04-01T08:00:00
|
|
```
|
|
|
|
`/schedule` is available in the Claude web interface. It queues a headless
|
|
Claude Code run for the specified time. Combines with the Telegram permission
|
|
relay (v2.1.81) for approval-gated automation.
|
|
|
|

|
|
|
|
## Why This Matters
|
|
|
|
OpenClaw uses HEARTBEAT.md as a persistent loop marker. Claude Code achieves
|
|
the same outcome with more granularity: /loop for in-process polling, CronCreate
|
|
for system scheduling, /schedule for remote triggering. The `automation/` directory
|
|
in this repo provides macOS launchd examples as an alternative to cron.
|
|
|

|
|
|
|
## Carry Forward
|
|
|
|
With scheduling configured, your pipeline runs itself:
|
|
|
|
- **Example 09** adds safety guardrails to protect automated runs
|
|
- **Example 10** is the pipeline that your cron job triggers
|
|
- **Example 12** lets you monitor and control scheduled runs from your phone
|
|
|
|
Automation is the multiplier. Everything you built in examples 01-07 runs once when you trigger it. With scheduling, it runs every day, every week, or every time a condition is met.
|
|

|
|
|
## The Cumulative Path
|
|
|
|
> If you ran Examples 01-07, you have a complete pipeline with delivery.
|
|
> This prompt schedules it to run automatically.
|
|
|
|
```
|
|
Create a cron job that runs every Monday at 07:00 to execute:
|
|
1. Web research on a topic from memory/research-state.md
|
|
2. Multi-agent review via the researcher/writer/reviewer agents
|
|
3. Save output to pipeline-output/
|
|
4. Send a Telegram notification with the summary
|
|
|
|
Use automation/daily-briefing.sh as a template for the wrapper script.
|
|
Show me the cron entry before creating it so I can verify.
|
|
```
|
|
|
|
After running this, your Monday mornings start with a fresh research report waiting on your phone.
|

|
## Now Try It Yourself
|
|
|
|
Think about what you would automate if it cost zero effort:
|
|
|
|
**Option 1: /loop (for testing)**
|
|
```
|
|
/loop interval=300
|
|
|
|
Every 5 minutes, check if [your trigger condition]. If true,
|
|
[execute your pipeline]. Write results to [your output location].
|
|
```
|
|
|
|
**Option 2: CronCreate (for production)**
|
|
```
|
|
Create a cron job that runs [your task] every [schedule].
|
|
Use [wrapper script] and show me the cron entry first.
|
|
```
|
|
|
|
**Option 3: /schedule (for remote)**
|
|
```
|
|
/schedule "[your task description]" at [ISO datetime]
|
|
```
|
|
|
|
**The pattern you just learned:** trigger condition + pipeline steps + output destination. The three approaches cover different needs: /loop for development, CronCreate for system-level, /schedule for remote.
|
|
|
|
Ideas worth trying:
|
|
- Weekly competitor monitoring report every Monday
|
|
- Daily inbox summary from your email MCP at 08:00
|
|
- Hourly check for new entries in a data source you monitor
