wiki-update
Sync the current project's knowledge into the Obsidian wiki. Use this skill from any project when the user says "update wiki", "sync to wiki", "save this to my wiki", "update obsidian", or wants to distill what they've been working on into their knowledge base. This is the cross-project skill that lets you push knowledge from wherever you are into the vault. Accepts inline named-vault routing like "@work update wiki" via the shared Config Resolution Protocol.
npx skills add Ar9av/obsidian-wiki --skill wiki-update --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# 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 1. **Resolve config** — follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (inline `@name` override → walk up CWD for `.env` → `~/.obsidian-wiki/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. 3. Read `$OBSIDIAN_VAULT_PATH/.manifest.json` to check if this project has been synced before. 4. Read `$OBSIDIAN_VAULT_PATH/index.md` to know what the wiki already contains. When writing internal links in Steps 4–5, apply the link format from `llm-wiki/SKILL.md` (Link Format section) using the `OBSIDIAN_LINK_FORMAT` value. ## Step 1: Understand the Project Figure out what this project is by scanning the current working directory: - `README.md`, docs/, any markdown files - Source structure (frameworks, languages, key abstractions) - `package.json`, `pyproject.toml`, `go.mod`, `C

How do I install it?
Run `npx skills add Ar9av/obsidian-wiki --skill wiki-update --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Ar9av/obsidian-wiki, a repository with 3,115 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
