What problem does it solve? Project knowledge—architecture decisions, design rationale, and hard-won patterns—gets lost in git history and code. This Skill syncs what you've been working on into your Obsidian wiki so you can rediscover it months later without re-deriving the reasoning. ## Core Features & Use Cases - Delta-aware syncing: Tracks the last synced commit per project in .manifest.json, detects rebases or force-pushes, and falls back to a full scan when history is unreachable. - Structured distillation: Creates project overview pages plus concept, skill, and reference pages with YAML frontmatter, provenance markers (extracted/inferred/ambiguous), and confidence scores. - Cross-linking and tracking: Updates index.md, log.md, and hot.md, adds wikilinks between related pages, and optionally refreshes a QMD search index. - Use Case: After finishing a feature in any repo, say "update wiki" and the Skill scans the project, computes what changed since the last sync, and writes distilled architecture notes into your vault. ## Quick Start From any project directory, ask the assistant to update your wiki with what you've been working on, optionally naming a vault like "@work update wiki".
