## Description

Sync knowledge from the current project into the Obsidian wiki. Use when work already in the current project should be distilled into the vault; named-vault routing includes @work update wiki. wiki-capture saves the current conversation and wiki-ingest handles external/new sources.

# 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.

1. **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.
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`, `Cargo.toml` or whatever defines the project
- Git log (focus on commit messages that signal decisions, not "fix typo" stuff)
- Claude memory files if they exist (`.claude/` in the project)

Derive a clean project name from the directory name.

## Step 2: Compute the Delta

Check `.manifest.json` for this project:
