What problem does it solve? Over time, the tasks/completed/ directory accumulates hundreds of finished task files, making project history hard to navigate and bloating the working context. This Skill compacts completed tasks into dense, single-file milestone summaries and archives the originals. ## Core Features & Use Cases - Milestone Summarization: Scans all completed task files and generates a structured summary at docs/history/milestone-X-summary.md, including source distribution, architectural changes, files modified, and acceptance criteria status. - Automated Archiving: Moves completed task files from tasks/completed/ to tasks/archive/ using git mv, staging the new summary and moved files for commit. - Memory Bank Audit: After compaction, audits the project memory bank via list_namespaces and search_memory to detect stale, superseded, or duplicate memory entries, producing a Stale Memory Report that requires Manager approval before any deletion. - Use Case: At the end of a development milestone, run this Skill to condense 25 completed task files into one milestone summary document, archive the originals, and flag outdated memory entries for review. ## Quick Start Run the archive-tasks skill to compact all completed tasks in tasks/completed/ into a new milestone summary and move them to the archive.
