+# Vault Autopilot — Project Instructions
+
+## What This Is
+
+A general-purpose Obsidian plugin. When a new file appears in a watched folder, it reads a user-configured SOP/prompt, calls an AI provider, and writes the output as a note.
+
+This is a standalone repo at `~/Documents/fang/vault-autopilot/`. All paths in this repo use no prefix — `src/`, `tests/`, `docs/` are at the root.
+
+## Implementation Plan
+
+`docs/superpowers/plans/2026-05-30-vault-autopilot-v3.md`
+
+The plan has Tasks 0–9 (Task 10–11 are Chrome extension + integration tests, done separately).
+
+## Core Development Principles
+
+### TDD — Non-negotiable
+Every Task with logic must:
+1. Write failing tests first
+2. Run tests — confirm they fail
+3. Implement the code
+4. Run tests — confirm they pass
+5. Commit
+
+Tasks 0 (scaffold), 1 (types), 8 (settings UI), 9 (main.ts) have no unit tests — commit directly after implementing.
+
+### YAGNI — Strict
+Only implement what the plan explicitly requires. No extra error handling, no extra abstractions, no "nice to haves".
+
+### Task Isolation
+- One commit per Task
+- Never merge two Tasks into one commit
+- Never implement Task N+1 work while doing Task N
+
+### Sub-agent Execution
+Each Task is implemented by an independent sub-agent. After implementation, run two review passes:
+1. Spec compliance — does it match the plan?
+2. Code quality — YAGNI, no unnecessary complexity
+

+## Commands
+
+```bash
+npm test              # run all tests
+npx jest <file>       # run single test file
+npm run build         # tsc check + esbuild bundle → main.js
+npm run dev           # esbuild watch mode
+```
+
+## Git Rules
+
+- `main.js` is gitignored (build artifact). To release: `git add -f main.js`
+- Commit messages: `feat: <what>` for new code, `fix: <what>` for bug fixes
+- Never `--no-verify`
+
+## Forbidden
+
+- Do not add features not in the plan
+- Do not merge Task commits
+- Do not skip the TDD red→green cycle
+- Do not add comments explaining what code does (only WHY if non-obvious)
