/install openclaw-skill-cron-scheduler
Description
Manage cron jobs on macOS/Linux - list, add, remove, backup, and schedule recurring tasks
Usage Guidance
This skill appears coherent with its purpose, but review the included script before running: 1) Inspect scripts/cron-helper.sh locally for any unexpected commands. 2) Be aware service start/stop calls use sudo and will prompt for your password; only run those if you expect to control system services. 3) The script has some minor code-quality issues (cron expression validation is basic and the 'remove by line' logic looks fragile); test additions/removals on a non-critical account and verify backups in ~/.cron-backups before restoring. 4) If you don't trust the author or source, run the script in a sandbox or manually implement the small operations you need instead of granting execution rights.
Capability Analysis
Type: OpenClaw Skill
Name: openclaw-skill-cron-scheduler
Version: 1.0.0
The skill is a standard utility for managing cron jobs on macOS and Linux via the `scripts/cron-helper.sh` bash script. It provides expected functionality such as listing, adding, removing, and backing up crontabs using system-native commands like `crontab`, `systemctl`, and `launchctl`. The script includes safety features such as basic cron expression validation and automatic backups to `~/.cron-backups/`, and shows no evidence of malicious intent, data exfiltration, or unauthorized persistence.
Capability Assessment
Purpose & Capability
Name/description match the provided files. The script manipulates the user's crontab, manages backups under $HOME/.cron-backups, and uses sudo only for service start/stop—these are coherent with a cron-management tool.
Instruction Scope
SKILL.md and README instruct the agent/user to make the script executable and optionally add it to PATH; runtime instructions and script operations stay within cron management (reading/modifying crontab, writing backups under HOME, calling systemctl/launchctl with sudo). No instructions attempt to read unrelated files, external credentials, or send data off-host. Note: the script will launch an editor for 'edit' and prompts for confirmation on restore.
Install Mechanism
Instruction-only skill with an included shell script; no install spec or remote downloads. Low installer risk because nothing is fetched or executed automatically from external sources.
Credentials
No environment variables or credentials are requested. The script uses $HOME and standard commands (crontab, systemctl/launchctl) which are appropriate for its function. It may invoke sudo for service control, which is expected for starting/stopping system daemons.
Persistence & Privilege
always is false and the skill does not request persistent elevated privileges. It writes backups to a user-owned directory and does not modify other skills or global agent config.
How to Use
