loop

A recurring-task tool for Codex that runs a prompt again at a chosen interval. It can also show, pause, resume, cancel, and finish those tasks.

In plain words
What is it for?
Repeated jobs such as checking a deployment every few minutes. It also helps manage the scheduled runs afterward.
Why use it?
It removes the need to remember and manually repeat checks or other prompts. It can keep task runs tied to a visible Codex session.

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

loop 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 2d 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.

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex Loop

This skill is the user-facing entrypoint for the Codex Loop plugin. It parses the user intent, calls the codex_loop MCP tools, and relies on codex-loopd or the optional Stop hook fallback to trigger future iterations. New tasks default to visibility_policy=visible_only and runner=app-server: if the task cannot bind to a concrete current Codex session/thread id, or no app-server runtime is configured, it pauses instead of starting a hidden new session. The MCP tool starts codex-loopd automatically when the selected runner is runnable unless CODEX_LOOP_AUTOSTART=0.

Supported user forms

  • $loop 5m check deploy
  • $loop check deploy
  • $loop 15m
  • $loop
  • $loop list
  • $loop cancel <job_id>
  • $loop pause <job_id>
  • $loop resume <job_id>
  • /prompts:loop 5m check deploy

For Claude Code style visible loop turns, launch Codex through the repository script first:

  • codex-loop tui --cwd <repo>

This starts a local app-server runtime, starts codex-loopd against it, writes the active runtime marker, and opens codex --remote with the CODEX_LOOP_APP_SERVER, token file, and runtime DB environment needed by visible_only loop tasks.

Behavior

  1. If the request is create-like, call mcp__codex_loop__loop_create with:
    • raw_user_input: the raw arguments after $loop or /prompts:loop
    • cwd: current working directory
    • thread_id: the current Codex thread id. Prefer the CODEX_THREAD_ID environment variable. If it is not already visible, run printf '%s\n' "$CODEX_THREAD_ID" and pass the non-empty value.
    • approval_policy, sandbox, model: current snapshots if known; omit unknown values
  2. If the user asks for list/status, call mcp__codex_loop__loop_list.
  3. If the user asks to cancel/delete/rm, call mcp__codex_loop__loop_delete with job_id.
  4. If the user asks pause/resume, call mcp__codex_loop__loop_update.
  5. After a scheduled iteration prompt explicitly asks you to complete the iteration, call mcp__codex_loop__loop_complete_iteration.
    • Include both job_id and run_id when the prompt provides them. Completion is idempotent per run_id.

What ships with it

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.

loop is a skill published in the GitHub repository Owen718/codex-loop-plugin (9 stars, last pushed 4mo ago), licensed MIT. It adds 54 tokens to every session and 863 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-31.
