What problem does it solve? Archiving completed OpenSpec changes one at a time is repetitive and error-prone, especially when multiple changes touch the same capability specs. This Skill batch-archives changes while detecting and resolving spec conflicts by inspecting the actual codebase. ## Core Features & Use Cases - Batch archiving: Select and archive multiple completed changes in a single operation, moving each to openspec/changes/archive/YYYY-MM-DD-<name>. - Conflict detection and resolution: Detects when 2+ changes touch the same capability spec, then checks the codebase to determine which changes are actually implemented and applies specs in chronological order. - Status validation: Verifies artifact completion, task checkboxes in tasks.md, and GitHub tracking issues before archiving, blocking incomplete changes unless explicitly overridden. - Housekeeping automation: Syncs delta specs to main specs, updates feature docs, merges entries into CHANGELOG.md using Keep a Changelog categories, and optionally closes GitHub tracking issues. - Use Case: After finishing a sprint with three completed changes (webhooks, pagination fix, CSV export), archive all three at once with spec sync and changelog updates handled automatically. ## Quick Start Ask the assistant to archive all completed OpenSpec changes in bulk and confirm the selection when prompted.
