Wiki Update

You're working on a project and realize you just solved something worth remembering. This syncs your current work into an Obsidian vault from anywhere in your filesystem. It reads your code, git history, and docs to figure out what changed since last sync, then distills architecture decisions, trade-offs, and non-obvious patterns into wiki pages. The provenance system marks what's extracted from code versus inferred reasoning. It's opinionated about what matters: why you chose something, not file listings. Works across projects with config resolution that walks up from your current directory. If you keep an Obsidian knowledge base and want project insights automatically captured without manual note-taking, this is the sync layer.

Wiki Update — Sync Any Project to Your Wiki

You are distilling knowledge from the current project into the user's Obsidian wiki. This skill works from any project directory, not just the obsidian-wiki repo.

Before You Start

Writing profile: Before drafting or rewriting natural-language Markdown, read and apply the Writing Profile Resolution section in llm-wiki/SKILL.md. Framework schema, provenance, safety, and operation-specific requirements take precedence. WRITING.md preferences apply only to newly drafted or rewritten natural-language Markdown; preserve source content and structured records.

Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → global config → prompt setup). This gives OBSIDIAN_VAULT_PATH, OBSIDIAN_WIKI_REPO, OBSIDIAN_LINK_FORMAT (wikilink default or markdown), and optional QMD settings such as QMD_WIKI_COLLECTION. Works from any project directory.
Read $OBSIDIAN_VAULT_PATH/.manifest.json to check if this project has been synced before.
Read $OBSIDIAN_VAULT_PATH/index.md to know what the wiki already contains.
