Slice Closure
Decide whether the current slice is ready to close, distinguishing slice completion from full task completion, then persist the result in slice notes and TASK_STATE.md as explicit reviewable closure notes. For single-slice tasks may route directly to delivery. Returns no-op when slice memory would not materially change. Use when a slice was just implemented, slice-level validation was completed or reviewed, or the next decision is whether this slice can be closed cleanly. Do not use when no concrete slice implementation happened yet, the task is still in broad planning or contract work, or the goal is to understand overall task progress (use where-we-at). Before closing a long session, use harvest-session-learnings to capture durable lessons.

When should I use the Slice Closure skill?
Use Slice Closure when your Claude Code task falls under the General category — specifically in the education learning area.

Browse related skills at
/category/general/.
What is a Claude Code skill and how does the Slice Closure skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Slice Closure is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category. Learn more at
