Planning With Files

Implements the "Manus-style" three-file pattern (task_plan.md, notes.md, deliverable.md) to give Claude persistent memory across context resets. Instead of relying on volatile TodoWrite tools, you track phases with checkboxes, log failures, and store research in markdown files. The core idea is simple: re-read your plan before making decisions so goals don't drift after 50 tool calls. Use it for multi-step tasks, research projects, or anything that needs organization beyond a single response. Skip it for quick edits or simple questions. The approach borrows directly from context engineering patterns that made Manus AI's agents more reliable, treating the filesystem as external memory rather than stuffing everything into context.
