Use when configuring which document types a vault tracks: after installing ai-brain-starter, when a new kind of note appears (journals, books, meetings, clients, podcasts, travel, WhatsApp/Slack/iMessage exports), when extraction skips files because no extractor matches their type, or to add, list, or remove a custom type. Triggers: /setup-vault-types, "set up vault types", "add a note type", "enable an extractor". NOT for running extraction (use /second-brain-mapping).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /setup-vault-types
> **`{SKILL_DIR}`** = this skill's own folder (locally: the directory this SKILL.md lives in; a served brain substitutes the real absolute path before you read this). Shared starter files live at the repo root two levels up: `{SKILL_DIR}/../..`. If a path does not resolve, name the missing file and stop — never guess another location.
Figure out which doc types belong in this vault, then wire the right extractors.
## Why
`/second-brain-mapping` ships with 18 extractors. You probably don't need all of them. This wizard:
1. Asks what kinds of notes you take
2. Enables the matching extractors
3. Offers to scaffold new extractors for types we don't ship
No "start small" suggestion. You get all the capability for the types you have.
## Steps
### Step 1 — Detect existing types
Scan the vault for files already declaring `type:` in frontmatter:
```bash
cd "$(vault-root)"
grep -rh "^type:" --include="*.md" -I . 2>/dev/null \
| sed 's/^type:\s*//' | sort | uniq -c | sort -rn | head -30
```
Tell the user: *"Your vault already has these types declared: …"*
### Step 2 — Ask what they take notes on
Present this list, ask user to pick any/all that apply:
```
…Read the whole file at its exact version.
How to install
mdr add mycelium-hq/ai-brain-starter/setup-vault-types@sha256:9612d0e2e77f5005The line at the top of this page pins the label git:20260825.acebc75, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
