YALC-the-GTM-operating-system: Skill for Claude Code

.claude/skills/cross-platform-scheduler/SKILL.md

cross-platform-scheduler is a skill for Claude Code from Othmane-Khadri/YALC-the-GTM-operating-system. It costs 0 tokens per session (685 once invoked), scanned A, original, MIT.

A background scheduler for YALC agents, where each agent is described in a YAML file. It uses cron-style schedules to run agents on macOS, Windows, and Linux, including after setup for persistent operation.

In plain words
What is it for?
Checking registered agents, starting the scheduler, viewing setup instructions, and keeping scheduled agents running across reboots.
Why use it?
It provides one way to start scheduled agents and check whether they are running without relying on separate operating-system scheduling tools.

Written for Claude Code: installed under .claude/.

This is Othmane-Khadri/YALC-the-GTM-operating-system's own configuration. It tells Claude Code how to work on YALC-the-GTM-operating-system itself, so it is not a mod to install elsewhere.

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

cross-platform-scheduler 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 12d 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.

cross-platform-scheduler

Manage the YALC cross-platform background agent scheduler — start it, check status, or show setup instructions for keeping it alive across reboots.

Triggers

Use this skill when the user says:

  • "start my scheduled agents"
  • "is my scheduler running"
  • "how do I run agents on Windows"
  • "set up scheduled agents"
  • "agent cron", "cron for agents", "schedule agents"
  • "keep agents running in the background"
  • "scheduler status"

What this skill does

YALC background agents are defined as YAML files in ~/.gtm-os/agents/. The cross-platform scheduler reads those YAMLs and runs each agent on its declared schedule using node-cron — no OS-level plumbing, works on macOS, Windows, and Linux.

Procedure

Step 1 — Check for agent YAMLs

Run:

npx tsx src/cli/index.ts scheduler:status

If output is "No agents found", the user needs to install a framework first (framework:install <name>) or create a custom agent (agent:create). Stop here and guide them.

Step 2 — Start the scheduler

npx tsx src/cli/index.ts scheduler:start

This is a long-lived process. It prints each registered agent and its cron expression, then runs indefinitely.

Step 3 — Keep it alive across reboots (optional)

Ask the user if they want the scheduler to survive reboots. If yes:

Any platform (requires pm2):

npm install -g pm2
pm2 start "npx tsx /path/to/yalc-internal/src/cli/index.ts scheduler:start" --name yalc-scheduler
pm2 save
pm2 startup   # follow the printed command to register with the OS

macOS only (launchd, no pm2 needed): The existing agent:install --agent <id> command still writes a launchd plist for macOS users who prefer native scheduling.

Schedule format reference

Agent YAMLs support these schedule shapes:

# Daily at 08:00
schedule:
  type: daily
  hour: 8
  minute: 0

# Weekly Monday at 09:00
schedule:
  type: weekly
  hour: 9
  minute: 0
  dayOfWeek: 1

# Every 30 minutes
schedule:
  type: interval
  intervalMinutes: 30

# Raw cron passthrough
schedule:
  type: cron
  expression: "0 9 * * 1-5"  # weekdays at 09:00

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.

cross-platform-scheduler is a skill published in the GitHub repository Othmane-Khadri/YALC-the-GTM-operating-system (301 stars, last pushed 22d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 685 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
