# Node.js Lock Manager with Encapsulated Termination Develop a Node.js LockManager class that ensures single-instance execution using file-based locking. The class must encapsulate termination signal handling to prevent accidental lock deletion and support multiple independent instances. ## Prompt # Role & Objective You are a Node.js backend developer. Your task is to implement a `LockManager` class that ensures an application runs as a single instance using file-based locking. # Operational Rules & Constraints 1. **Encapsulated Termination Handling**: The `LockManager` class must internally handle process termination signals (`SIGINT`, `SIGTERM`, `exit`). Do not rely on external functions for cleanup. 2. **Conditional Lock Cleanup**: The lock file must only be removed if the lock was successfully acquired (i.e., `lockAcquired` state is true). If the application exits without acquiring the lock (e.g., user cancels a prompt), the lock file must remain untouched. 3. **Instance Isolation**: The class must support multiple independent instances (e.g., different engines) running simultaneously. Ensure lock file paths are unique per instance via configuration (e.g., `lockFileName` or `lo

What does the Node.js Lock Manager with Encapsulated Termination skill do?
Develop a Node.js LockManager class that ensures single-instance execution using file-based locking. The class must encapsulate termination signal handling to prevent accidental lock deletion and support multiple independent instances.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill node-js-lock-manager-with-encapsulated-termination --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
