What problem does it solve? AI coding agents lose track of goals during long multi-step tasks because context windows are volatile and get compacted or cleared. This Skill stores task plans, findings, and progress as markdown files on disk, so work survives /clear, compaction, and session restarts. ## Core Features & Use Cases - Persistent three-file planning: Creates and maintains task_plan.md, findings.md, and progress.md in the project directory as external working memory. - Hook-based context injection: UserPromptSubmit, PreToolUse, PostToolUse, Stop, and PreCompact hooks re-inject plan state automatically, with optional SHA-256 attestation to block tampered plans. - Parallel and gated modes: Supports isolated per-task plan directories under .planning/, plus autonomous and gated modes with a completion gate, ledger summaries, and runaway guards. - Use Case: An agent running a 50-step refactor creates task_plan.md, logs each phase and error, and after a /clear resumes exactly where it left off by re-reading the plan files. ## Quick Start Ask the agent to plan out your multi-step project using planning files so it creates task_plan.md, findings.md, and progress.md before starting work.
