Seamlessly resume AI coding agent work sessions
Install & Use
Copy this prompt and send it to your AI assistant (Claude / Cursor / TRAE / Codex / WorkBuddy etc.) to auto-install:

This Skill solves the problem of losing context, repeating work, or overwriting existing modifications after an AI coding agent session is interrupted. In real-world development, developers often need to switch between multiple AI coding agents (such as Claude Code, Codex, Cursor, etc.) or lose progress due to terminal closures or session timeouts, forcing them to start from scratch by re-describing the current task state—wasting time and increasing the risk of errors.
Usage is straightforward: simply install the Skill into your target AI agent using the npx skills add command. Thereafter, before starting a new session, the AI agent will automatically execute a standard workflow: it first locates the most recent session record (transcript, exported file, or summary), fully reads the context, reconstructs the original goal, completed work, decision points, and stopping position, then extracts unfinished tasks and prioritizes resuming from the first incomplete step. The entire process requires no manual intervention and is fully driven by the AI agent.
It is ideal for teams or individuals who frequently switch between multiple AI coding agents or work on long-term development projects requiring continuity across sessions. This is especially useful for developers already using tools like Claude Code, Codex, Cursor, OpenCode, or GitHub Copilot who want a unified workflow. Whether you're an independent developer or part of a team, this Skill significantly reduces repetitive communication and context-rebuilding overhead.
It is recommended to adopt this tool when starting a new project or taking over someone else's code. Note that it primarily relies on the AI agent's ability to understand instructions; if session records are too fragmented or missing, you may need to manually provide some key information. Additionally, when running multiple agents, the Skill operates in 'hard mode'—requiring context reconstruction from each agent's transcripts—so performance may degrade in multi-agent scenarios.
Key Features
Unlike Kontinuo (an advanced tool by the same author), agent-session-resume is a lightweight, reusable Skill embedded directly into the AI agent's instructions, requiring no standalone service or network connection; whereas Kontinuo requires running a checkpoint service and depends on external storage.
Limitations
Requires Python 3 standard library and only supports AI agents where this Skill is installed (e.g., Claude Code, Codex, Cursor, etc.). It does not support AI tools that lack a SKILL instruction loading mechanism.
FAQ
How do I install it?
Run `npx skills add hacktivist123/agent-session-resume` for interactive installation, or specify agents like `-a claude-code -a codex`.
Which AI agents are supported?
Claude Code, Codex, Cursor, Antigravity, OpenCode, GitHub Copilot, etc., via the `npx skills` tool.
