What problem does it solve? When running multiple projects in parallel, each project accumulates its own learnings and retrospective notes, but that knowledge stays siloed. This Skill consolidates those insights into a single aggregation log so cross-project patterns become visible and reusable. ## Core Features & Use Cases - Cross-Project Collection: Reads learnings and retrospectives from every project listed in registry.yaml, respecting aggregate: false exclusions to keep client engagements isolated. - Deduplication & Freshness: Pulls each project's latest main branch and compares against the existing aggregation log to avoid duplicate entries. - Pattern Detection: Identifies cross-cutting patterns (recurring failures, slow tasks, skill gaps) and reconciles them against templates and the propagation log before recommending action. - Use Case: Run weekly to merge a dozen project retros into docs/process/aggregation-log.md, then hand off flagged patterns to a propagation workflow that updates shared skills and templates. ## Quick Start Run the aggregate skill to pull the latest learnings and retros from all registered projects into the central aggregation log.
