Close Slice

Use this skill when implementation is complete and you want to close an execution slice cleanly.

Responsibilities

1. Resolve the target slice through guide-execution.
2. Validate that the slice is ready to close.
3. Close the slice without deleting the original artifacts.
4. Optionally record explicit invalidation or supersession relations as part of closure.

Source of Truth Rules

• Keep the original slice artifacts intact. close-slice records closure only; any later cleanup or archival is a separate explicit maintenance step.
• Treat <slice_dir>/README.md, <slice_dir>/registry.json, and <slice_path>/.slice-meta.json as the canonical closure records.

Artifact Ownership

close-slice owns closure metadata updates and relation-bearing slice closure.
