graceful-shutdown

graceful-shutdown is a skill for Claude Code, Codex from aj-geddes/useful-ai-prompts. It costs 50 tokens per session (678 once invoked), scanned A, original, MIT.

A guide to making a server shut down in an orderly way after receiving a stop signal. It covers finishing active requests, closing connections, and releasing resources before the process ends.

In plain words
What is it for?
Use it for Docker or Kubernetes deployments, rolling updates, server restarts, load-balancer draining, background jobs, and database connection cleanup.
Why use it?
It prevents restarts or deployments from cutting off work that is still in progress. This reduces failed requests and helps services stop cleanly.

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

graceful-shutdown 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-config.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Graceful Shutdown

Table of Contents

Overview

Implement proper shutdown procedures to ensure all requests are completed, connections are closed, and resources are released before process termination.

When to Use

  • Kubernetes/Docker deployments
  • Rolling updates and deployments
  • Server restarts
  • Load balancer drain periods
  • Zero-downtime deployments
  • Process managers (PM2, systemd)
  • Long-running background jobs
  • Database connection cleanup

Quick Start

Minimal working example:

import express from "express";
import http from "http";

class GracefulShutdownServer {
  private app: express.Application;
  private server: http.Server;
  private isShuttingDown = false;
  private activeConnections = new Set<any>();
  private shutdownTimeout = 30000; // 30 seconds

  constructor() {
    this.app = express();
    this.server = http.createServer(this.app);
    this.setupMiddleware();
    this.setupRoutes();
    this.setupShutdownHandlers();
  }

  private setupMiddleware(): void {
    // Track active connections
    this.app.use((req, res, next) => {
      if (this.isShuttingDown) {
        res.set("Connection", "close");
        return res.status(503).json({
          error: "Server is shutting down",
// ... (see reference guides for full implementation)
