description: "Initialize, adopt, and route work for a separate Obsidian knowledge vault through the portable claude-obsidian core. Use for vault setup, scaffolding, workspace selection, cross-project configuration, or choosing the correct wiki sub-skill. Triggers: /wiki, set up wiki, scaffold vault, create knowledge base, adopt this vault, Obsidian vault, second brain setup, persistent wiki."

Wiki orchestration

Treat the installed product as code and the selected user vault as data. Never use the plugin/product root as a vault, even when the current directory happens to be the product checkout.

Resolve the portable core from this skill's installation and invoke it by absolute path:

CORE=/absolute/product/root/scripts/claude-obsidian.py
python3 "$CORE" --help

Resolve a vault in this order: explicit `--vault`, `CLAUDE_OBSIDIAN_VAULT`, the nearest `.claude-obsidian.json`, then an unambiguous initialized vault at or above the current directory. Fail closed when selection is missing or ambiguous.

Baseline setup requires no network egress. Do not fetch templates, plugins, or remote content unless the user separately approves the destinations and budget.

Set up a vault

Use the deterministic setup commands. Both are dry-run by default.

For a new, separate vault:

python3 "$CORE" init /absolute/path/to/vault \
  --generated-at <ISO-UTC> --operation-id init-reviewed
python3 "$CORE" init /absolute/path/to/vault \
  --generated-at <ISO-UTC> --operation-id init-reviewed \
  --approved-plan-sha256 <reviewed-sha256> --apply

For an existing Obsidian vault:

python3 "$CORE" adopt /absolute/path/to/vault \
  --generated-at <ISO-UTC> --operation-id adopt-reviewed
python3 "$CORE" adopt /absolute/path/to/vault \
  --generated-at <ISO-UTC> --operation-id adopt-reviewed \
  --approved-plan-sha256 <reviewed-sha256> --apply

Before `--apply`, show the selected path and changed-path preview, then pass the emitted `approved_plan_sha256` unchanged. Do not use `--force` unless the user has reviewed the conflicts and explicitly approved replacement. Setup is non-destructive by default and creates no upstream Git remote.

If the user asks for a domain-specific scaffold, establish the baseline first, then read [modes.md](references/modes.md). Draft the additional pages and configuration as one operation-level transaction. Never mutate vault files with host Write/Edit tools or an Obsidian transport.

Route operations

Route the user's intent without silently broadening it:

| Intent | Skill | |---|---| | Ingest supplied sources | `wiki-ingest` | | Answer from existing vault knowledge | `wiki-query` | | Save a specific conversation result | `save` | | Research the public web under a budget | `autoresearch` | | Check vault health | `wiki-lint` | | Roll up log entries | `wiki-fold` | | Work with a canvas | `canvas` |

Query is read-only. Persistence from a query must be an explicit, separately scoped Save operation. Never capture a transcript or update the hot cache merely because a session ended.

Mutation contract

Read [operation-transactions.md](references/operation-transactions.md) before any custom scaffold or mutation. One logical operation must produce one inspected and recoverable `claude-obsidian.transaction.v1` bundle. Parallel agents may return drafts and evidence only; the orchestrator merges them and applies once. Every canonical page create or removal includes an active index or MOC update in that bundle; update the overview only when the stable high-level picture changed. Raw source payloads are create-only. There are no automatic commits.

Use [provenance.md](references/provenance.md) when initializing or changing source and claim ledgers. Unsupported evidence stays unsupported; never invent a source, quote, date, locator, or confidence.

After a successful apply, report the operation ID and exact changed paths. If the user explicitly wants a Git checkpoint, run it separately:

python3 "$CORE" checkpoint OPERATION_ID --vault /absolute/path/to/vault

On a conflict, re-read and rebuild. On interruption, use `transaction recover`. Reuse an operation ID only with the identical bundle.

Installation context

Read [install-modes.md](references/install-modes.md) when installation or host behavior matters. Hooks are optional adapters; portable behavior lives in the core and skills.

Conditional references

Read only the reference needed for the current request:

• [frontmatter.md](references/frontmatter.md) when defining or adopting a

property schema;

• [css-snippets.md](references/css-snippets.md) for requested Obsidian visual

customization;

• [git-setup.md](references/git-setup.md) for explicit local Git or checkpoint

setup;

• [plugins.md](references/plugins.md) when evaluating optional Obsidian

integrations;

• [mcp-setup.md](references/mcp-setup.md) when the user asks to evaluate an

external read transport;

• [rest-api.md](references/rest-api.md) only when the user explicitly has or

requests the Local REST API adapter.

Think, verify, grow

Before applying, pause once: observe existing state, verify the vault selection and evidence, then choose the smallest reversible operation that satisfies the request. Afterward, report uncertainty and the next useful improvement without performing it automatically.
