Planning With Files is an open-source framework that provides persistent, file-based planning for AI coding agents and long-running agentic tasks. It addresses the challenge of context loss in LLM-based agents by storing agent plans as markdown files on disk, ensuring that progress survives crashes, context windows resets, or commands like /clear. The core idea is to give an agent a structured set of files (typically plan.md, status.md, and completion gates) that act as external memory, allowing deterministic recovery and continuation of complex multi-step tasks. The system implements a deterministic completion gate using JSON files with check-fields that must be explicitly passed to mark a task as done, preventing false completions. This makes the agent's workflow auditable and reliable. The framework is designed to be agent-agnostic via the SKILL.md standard, which has been adopted by over 60 different AI coding assistants including Claude Code, Codex, OpenCode, and Continue.dev. It includes plugins and skill definitions for seamless integration into various coding environments. Key technical features include non-blocking stop signals, PreCompact parity to optimize context usage before compactions, and robust handling of control characters in gate JSON. Version 3.1.0 introduced significant stability improvements such as stop_hook_active detection and refusal of unattested plan injection in autonomous modes. The project is actively maintained with a large community (23.2k GitHub stars, 2k forks) and receives frequent updates. The framework is particularly suited for autonomous coding agents that need to execute long sequences of operations—such as refactoring, code generation, or multi-file edits—without human intervention. It also supports multi-agent coordination by providing a shared, file-based planning layer that agents can read and update, enabling complex orchestrations of agentic workflows.
