What problem does it solve? Long agent sessions lose track of goals because context windows are volatile and limited. This Skill treats the filesystem as external memory, persisting plans, findings, and progress in markdown files so work survives 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. - Parallel Plan Isolation: Supports multiple concurrent plans under .planning/<date>-<slug>/ with an active-plan pointer and PLAN_ID pinning. - Tamper Protection: Optional SHA-256 attestation locks the plan file; hooks block injection of plan content if the file diverges from the approved hash. - Use Case: When asked to break down a research project or multi-phase build, the agent creates the three planning files first, re-reads the plan before decisions, and logs every error to avoid repeating failures. ## Quick Start Ask the agent to plan out your multi-step project using planning files, for example: "Plan and track the backend refactor using task_plan.md, findings.md, and progress.md."
