12-Factor AI Task Scheduler: Idempotent & Checkpoint Recovery

12-Factor AI Task Scheduler: Idempotent & Checkpoint Recovery

This AI Agent skill for Claude Code, Cursor, and Codex coordinates recurring tasks using an idempotent scheduling protocol with robust checkpoint recovery. It ensures tasks' consistent execution through state management and error compression, providing a reliable scheduling solution for complex workflows.

What this skill does

• Initializes job execution by reading STATE.md for Idempotency Keys.
• Generates a unique key for the current task cycle using the format {job}-{YYYYMMDD}-{batch}, preventing repeat executions.
• If the key is already present, the job cycle is verified as completed, and the skill exits quietly.
• Executes the primary logic, with progress checkpoints written back to STATE.md every specified unit interval.
• Stores intermediate artifacts on disk within directories named by date, maintaining context isolation.
• Summarizes results and updates STATE.md with progress data and the task cycle key.
• Monitors task status, records successful completions, and initiates a compressed error recovery retry in the event of failure.

Who it is for

This skill benefits developers and teams utilizing AI coding agents — such as Claude Code, Cursor, or Codex — who require a structured, repeatable task scheduling mechanism in their software development or automation workflows.

Use cases

• Scheduling routine data processing jobs with error resilience for AI-driven applications.
• Automating batch operations where task state consistency is critical to prevent redundant processing.
• Implementing fault-tolerant operations that handle failed tasks via automatic recovery mechanisms in development environments.

Technical details

• Utilizes a 12-factor architecture methodology for agent workflows.
• Employs state management via STATE.md and idempotency key tracking.
• Checkpoint-based execution for task progress logging and recovery.
• Error handling through monitoring and compressed error recovery protocols.
