+# Copilot & Cursor Rules — Update Guide
+
+This document explains where Cursor rules live, how to create or update them,
+and how to keep GitHub Copilot settings in sync.
+
+---
+
+## Where Cursor rules live
+
+All project-specific Cursor rules are stored under **`.cursor/rules/`**.  
+Each rule is a `.mdc` file (Markdown + metadata front-matter):
+
+```
+.cursor/
+└── rules/
+    ├── Compliance-Legal-Rules.mdc
+    ├── Monitoring-Quality-Rules.mdc
+    ├── Operational-Workflow-Rules.mdc
+    └── Strategic-Vision-Rules.mdc
+```
+
+Global (user-level) rules live in `~/.cursor/rules/` or are managed via
+**Cursor → Settings → Rules for AI**.
+
+---
+
+## Creating or updating rules
+
+Use the built-in **`create-rule`** skill (if available) for scaffolding:
+
+```bash
+# Example: scaffold a new rule called "Security-Rules"
+cursor skill create-rule Security-Rules
+```
+
+To edit an existing rule manually, open the `.mdc` file and update the
+front-matter (title, description, `alwaysApply`, `globs`) and the rule body.
+
+---
+
+## Keeping Copilot in sync
+
+When you update a Cursor rule that also affects GitHub Copilot behaviour,
+mirror the change in Copilot's instruction settings:
+
+| Setting | Location |
+|---|---|
+| Review selection instructions | `github.copilot.chat.reviewSelection.instructions` in VS Code / Cursor user settings |
+| Commit message instructions | `github.copilot.chat.commitMessageGeneration.instructions` |
+| Generate test instructions | `github.copilot.chat.generateTests.instructions` |
+
+The reference file for all custom Copilot/Cursor JSON overrides is
+**`cursor-user-settings-FIXED.json`** in the repository root (if present).  
+Apply it with the `install-cursor` skill or by copying the relevant keys into
+your editor's user `settings.json`.
+
+---
+
+## Workflow
+
+1. **Edit rule** — open the relevant `.cursor/rules/*.mdc` file and update.
+2. **Sync Copilot** — if the rule change affects code review or generation
+   instructions, update the corresponding Copilot setting (see table above).
+3. **Install settings** — run `install-cursor` skill or apply
+   `cursor-user-settings-FIXED.json` if prompted.
+4. **Commit & push** — rules are committed to the repo so the team shares
+   the same AI behaviour.
+
