Use when the user wants to map or remap their second brain, refresh the vault''s queryable metadata index, extract structured frontmatter from typed notes (books, meetings, people, journals, goals), fill wikilink gaps, or surface cross-type insights and patterns no single file shows. Triggers: /second-brain-mapping, "map my second brain", "make my vault queryable", "refresh vault metadata", stale or sparse Dataview fields. Not for single-file reads or querying an existing graph (use graphify).
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
# /second-brain-mapping
> **`{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.
Your vault is a database. This skill makes it queryable.
## What it does
| Phase | Tool | LLM cost | Always runs? |
|---|---|---|---|
| 1 | `vault-metadata-extract.py` (dispatcher → type-specific extractors) | **0 tokens** | Yes |
| 2 | `/graphify` (optional) | ~100k–1M tokens | No — asks first |
| 2b | `graphify_report_sanitize.py --check` — keeps the graph report from flooding the vault's graph view | **0 tokens** | Yes, whenever a report exists |
| 3 | Wikilink gaps + interactive apply | ~5k tokens | If graph exists |
| 4 | `vault-insight-engine.py` — cross-type surprise finder | **0 tokens** | Yes |

How to install
mdr add mycelium-hq/ai-brain-starter/second-brain-mapping@sha256:ff119a46ead1cb6aThe 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.
