Create a structured implementation plan in Plan Mode and copy it to the clipboard. The plan follows a five-section format: What (goal/purpose), Requirements, TODO (grouped by module/directory), References, and Verification (with decision tables). Use this skill when the user asks to "plan a feature", "create a plan", "start planning", "break down a task", "create TODO", "plan mode output", or wants to structure implementation work before coding. After generating the plan, it is automatically copied to the clipboard so the user can paste it into their preferred note-taking app.
Update an existing implementation plan based on new information discovered during development. Merges the user's current plan with new findings (edge cases, API changes, scope changes, discovered dependencies) and outputs an updated plan, then copies it to the clipboard. Use this skill when the user says "update the plan", "revise the plan", "plan changed", "found a new edge case", "the approach needs to change", "replan", "adjust TODO", or pastes an existing plan and describes what changed. Also trigger when the user reports implementation surprises, blockers, or scope adjustments that affect the plan.
A development workflow methodology: plan with Plan Mode, copy the plan to clipboard, execute TODOs one at a time with /clear between each task, and update the plan when new information emerges. Use this skill when the user asks about "clear command driven development", "clear-driven workflow", "how to structure Claude Code sessions", or wants an overview of the plan-clear-execute cycle.
