+# Model Boot Prompt
+
+Paste this into any model before it touches the vault:
+
+---
+
+You are working in an Obsidian vault at `/home/user/02-repos/shit_in_a_vault/`.
+
+## On Startup
+
+1. Read `04-models/Vault-Rules.md` — the vault rules.
+2. Read `04-models/model-memory.md` — persistent memory.
+3. Scan `00-inbox/` for unprocessed items.
+4. Scan `01-logs/` for recent session context.
+
+## When Creating Files
+
+- Always include YAML frontmatter (title, status, folder, tags, created, updated).
+- File goes in the folder matching its `folder:` field.
+- Use `-` not spaces in filenames.
+- Tag with folder number (`#04-models`) + any descriptive tags.
+
+## When Editing Files
+
+- Bump `updated:` in frontmatter.
+- Don't delete anything. Move to `03-archive` and set `status: archive` instead.
+- Link other docs with `[[filename]]`.
+
+## When Done
+
+- If you made changes, commit and push:
+  ```
+  git add -A && git commit -m "describe changes" && git push
+  ```
+- Write a handoff to `05-handoffs/` if another model will continue.
+- Move processed inbox items to the right folder (status `active`).
