c-cron

c-cron is a skill for Claude Code, Codex from daxaur/openpaw. It costs 27 tokens per session (346 once invoked), scanned A, original, MIT.

A helper for scheduling recurring commands with Unix cron and controlling macOS background services with `launchctl`. It uses `lunchy-go` as a simpler command-line wrapper for those macOS services.

In plain words
What is it for?
It helps list, start, stop, restart, and inspect macOS services, and create cron jobs that run commands at set times or intervals.
Why use it?
It puts recurring tasks and service control in one terminal workflow. The guidance also reduces common scheduling mistakes such as using relative paths or failing to capture command output.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

c-cron scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Scheduling & Cron

lunchy-go (launchctl wrapper)

Friendly wrapper around macOS launchctl:

# List all services (pattern match)
lunchy-go ls
lunchy-go ls redis

# Start a service
lunchy-go start com.example.service
lunchy-go start redis    # pattern match

# Stop a service
lunchy-go stop redis

# Restart a service
lunchy-go restart redis

# Show service status
lunchy-go status redis

crontab (built-in)

Standard Unix cron scheduler:

# List current cron jobs
crontab -l

# Edit cron jobs (opens editor)
crontab -e

# Cron syntax: MIN HOUR DOM MON DOW command
# Every day at 9am:
# 0 9 * * * /path/to/script.sh
# Every 5 minutes:
# */5 * * * * /path/to/script.sh
# Weekdays at 8:30am:
# 30 8 * * 1-5 /path/to/script.sh

Guidelines

  • Prefer lunchy-go for macOS services (launchd plists)
  • Use crontab for simple recurring commands
  • Always use full paths in cron jobs
  • Redirect output to log files: command >> /tmp/cron.log 2>&1
  • Test commands manually before scheduling them

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
