What problem does it solve? Long agent sessions lose track of goals because context windows are volatile and limited. This Skill implements Manus-style file-based planning, treating the filesystem as persistent external memory so multi-step projects survive context resets, compaction, and /clear. ## Core Features & Use Cases - Three-File Planning Pattern: Creates task_plan.md (phases and decisions), findings.md (research and discoveries), and progress.md (session log) in your project directory. - Session Recovery: A session-catchup script detects unsynced context from previous Claude Code, Codex, or OpenCode sessions after /clear, and a PreCompact hook flushes progress before compaction. - Parallel Plan Isolation: Supports multiple concurrent plans under .planning/<date>-<slug>/ with an active-plan pointer and PLAN_ID pinning per terminal. - Injection Defense: Wraps injected plan content in BEGIN/END delimiters and offers optional SHA-256 attestation that blocks injection if task_plan.md is tampered with. - Use Case: When asked to plan a multi-phase research or build project, the agent creates the three planning files first, re-reads the plan before decisions, logs every error, and resumes cleanly after context loss. ## Quick Start Ask the agent to plan out your multi-step project using planning files, and it will create task_plan.md, findings.md, and progress.md in your project root before starting work.
