# Backend Development Rules
## Database (Supabase)
- ALWAYS enable Row Level Security on every table
- Create RLS policies for SELECT, INSERT, UPDATE, DELETE
- Add indexes on columns used in WHERE, ORDER BY, and JOIN clauses
- Use foreign keys with ON DELETE CASCADE where appropriate
- Never skip RLS - security first
## API Routes
- Validate all inputs using Zod schemas before processing
- Always check authentication: verify user session exists
- Return meaningful error messages with appropriate HTTP status codes
- Use `.limit()` on all list queries
## Query Patterns
- Use Supabase joins instead of N+1 query loops
- Use `unstable_cache` from Next.js for rarely-changing data
- Always handle errors from Supabase responses
## Security
- Never hardcode secrets in source code
- Use environment variables for all credentials
- Validate and sanitize all user input
- Use parameterized queries (Supabase handles this)

# Frontend Development Rules
## shadcn/ui First (MANDATORY)
- Before creating ANY UI component, check if shadcn/ui has it: `ls src/components/ui/`
- NEVER create custom implementations of: Button, Input, Select, Checkbox, Switch, Dialog, Modal, Alert, Toast, Table, Tabs, Card, Badge, Dropdown, Popover, Tooltip, Navigation, Sidebar, Breadcrumb
- If a shadcn component is missing, install it: `npx shadcn@latest add <name> --yes`
- Custom components are ONLY for business-specific compositions that internally use shadcn primitives
## Import Pattern
```tsx
import { Button } from "@/components/ui/button"
import { Card, CardHeader, CardTitle, CardContent } from "@/components/ui/card"
```
## Component Standards
- Use Tailwind CSS exclusively (no inline styles, no CSS modules)
- All components must be responsive (mobile 375px, tablet 768px, desktop 1440px)
- Implement loading states, error states, and empty states
- Use semantic HTML and ARIA labels for accessibility
- Keep components small and focused
- Use TypeScript interfaces for all props
## Auth Best Practices (Supabase)
- Use `window.location.href` for post-login redirect (not `router.push`)
- Always verify `data.session` exists before redirecting
- Always reset loading state in all code paths (success, error, finally)

# General Project Rules
## New Project Detection (MANDATORY)
Before starting ANY work, check if the project has been initialized:
1. Read `docs/PRD.md` - if it still contains placeholder text like "_Describe what you are building_", the project is NOT initialized
2. Read `features/INDEX.md` - if the features table is empty, no features have been defined
**If the project is not initialized:**
- Do NOT write any code or create any components
- Do NOT skip ahead to implementation
- Instead, tell the user: "This project hasn't been set up yet. Let's start by defining what you want to build. Run `/init` with a description of your idea (e.g. `/init I want to build a task management app`)."
- If the user already described their idea in the current message, run `/init` automatically with their description
**If the project is initialized but the user requests a feature not yet in INDEX.md:**
- Guide them to run `/write-spec` first to create the feature spec before any implementation
## Feature Tracking
- All features are tracked in `features/INDEX.md` - read it before starting any work
- Feature specs live in `features/PROJ-X-feature-name.md`
- Feature IDs are sequential: check INDEX.md for the next available number
- One feature per spec file (Single Responsibility)
- Never combine multiple independent functionalities in one spec
## Git Conventions
- Commit format: `type(PROJ-X): description`
- Types: feat, fix, refactor, test, docs, deploy, chore
- Check existing features before creating new ones: `ls features/ | grep PROJ-`
- Check existing components before building: `git ls-files src/components/`
- Check existing APIs before building: `git ls-files src/app/api/`
## Human-in-the-Loop
- Always ask for user approval before finalizing deliverables
- Present options using clear choices rather than open-ended questions
- Never proceed to the next workflow phase without user confirmation
## Status Updates (MANDATORY - Write-Then-Verify)
After completing work on any feature, you MUST update tracking files. Follow this exact sequence:
1. **Read** the feature spec (`features/PROJ-X-*.md`) and `features/INDEX.md` BEFORE editing
2. **Write** your changes using the Edit tool — do NOT just describe what you would write
3. **Re-read** the file AFTER editing to verify the changes are actually present
4. **If changes are missing**, repeat step 2 — never claim updates were made without verifying
**What to update in the feature spec:**
- Status field in the header (Planned → In Progress → In Review → Deployed)
- Implementation notes: what was built, what changed, any deviations from the original spec
- Bug fixes or design changes discovered during implementation
**What to update in `features/INDEX.md`:**
- Feature status column must match the feature spec header
- Valid statuses: Roadmap → Planned → Architected → In Progress → In Review → Approved → Deployed
- **Roadmap**: after `/init` — feature identified, no spec file yet
- **Planned**: after `/write-spec`
- **Architected**: after `/architecture`
- **In Progress**: after `/frontend` or `/backend` starts
- **In Review**: after `/qa` starts
- **Approved**: after `/qa` passes (no critical/high bugs)
- **Deployed**: after `/deploy`
**NEVER do this:**
- Do NOT say "I've updated the feature spec" without actually calling the Edit tool
- Do NOT summarize changes in chat as a substitute for writing them to the file
- Do NOT skip updates because "it's obvious" or "minor"
## File Handling
- ALWAYS read a file before modifying it - never assume contents from memory
- After context compaction, re-read files before continuing work
- When unsure about current project state, read `features/INDEX.md` first
- Run `git diff` to verify what has already been changed in this session
- Never guess at import paths, component names, or API routes - verify by reading
## Handoffs Between Skills
- After completing a skill, suggest the next skill to the user
- Format: "Next step: Run `/skillname` to [action]"
- Handoffs are always user-initiated, never automatic

# Security Rules
## Secrets Management
- NEVER commit secrets, API keys, or credentials to git
- Use `.env.local` for local development (already in .gitignore)
- Use `NEXT_PUBLIC_` prefix ONLY for values safe to expose in browser
- Document all required env vars in `.env.local.example` with dummy values
## Input Validation
- Validate ALL user input on the server side with Zod
- Never trust client-side validation alone
- Sanitize data before database insertion
## Authentication
- Always verify authentication before processing API requests
- Use Supabase RLS as a second line of defense
- Implement rate limiting on authentication endpoints
## Security Headers
- X-Frame-Options: DENY
- X-Content-Type-Options: nosniff
- Referrer-Policy: origin-when-cross-origin
- Strict-Transport-Security with includeSubDomains
## Code Review Triggers
- Any changes to RLS policies require explicit user approval
- Any changes to authentication flow require explicit user approval
- Any new environment variables must be documented in .env.local.example
