thread-cron is a skill for Claude Code, Codex from PinkPig97/codex-thread-cron. It costs 21 tokens per session (326 once invoked), scanned A, original, Apache-2.0.

A guide for creating and managing recurring jobs inside a coding-agent conversation using cron schedules, time rules such as “every weekday at 9.”

In plain words
What is it for?
Use it to create, list, or delete thread-local recurring jobs, such as periodic reviews or reminders, when the local command-line build supports these cron operations.
Why use it?
It provides a defined way to schedule repeated work without treating each run as a new manual request.

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

thread-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 1mo 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

Use this skill when the user wants recurring work inside the current Codex thread and the local Codex build already supports native cron_create, cron_list, and cron_delete.

Guardrails

  • Prefer native thread cron over automation for recurring work in the current thread.
  • Do not fall back to automation unless the user explicitly asks for automation.
  • If native cron tools are unavailable, say so plainly and stop instead of inventing a workaround.

Workflow

  1. Normalize the task into three fields: name, schedule, and prompt.
  2. Prefer simple 5-field cron expressions that the current native parser supports.
  3. Keep prompts bounded, idempotent, and thread-local.
  4. After create, list, or delete, restate the exact schedule, prompt, or job id that was acted on.

Prompt Design Rules

  • Start with a verb: Review, Check, Summarize, Remind.
  • Keep scope narrow to one thread or one repository.
  • Avoid prompts that assume hidden context from a different session.
  • Prefer outputs that can be repeated safely without compounding side effects.

Schedule Rules

  • Supported syntax is numeric 5-field cron with *, lists, ranges, and steps.
  • Do not use aliases like @daily.
  • Do not use month or weekday names like JAN or MON.

Read references/recipes.md when the user needs example schedules or prompt templates.

Changes

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.
