Implementation rules and conventions for the entire project. The AI agent must follow these in every session without exception. These rules prevent pattern drift across sessions.

• [e.g. Think before implementing — understand what is being built and why before writing a single line]
• [e.g. Scope is sacred — only build what the current feature requires]
• [e.g. Clean over clever — simple readable code is always preferred]
• [e.g. One thing at a time — complete one feature fully before touching the next]

• [e.g. Strict mode enabled — no exceptions]
• [e.g. Never use any — use unknown and narrow the type]
• [e.g. All function parameters and return types must be explicitly typed]
• [e.g. Use const by default — only use let when reassignment is necessary]

• [e.g. Folders: kebab-case]
• [e.g. Component files: PascalCase]
• [e.g. Utility files: camelCase]
• [e.g. One component per file]

[Paste your preferred component or module structure here as a code snippet]
[e.g. imports → types → component/function → exports]

• [e.g. No inline styles — all styling via design tokens]
• [e.g. No business logic inside UI components]

[Paste your preferred route or controller structure here as a code snippet]

• [e.g. Every route validates the request before processing]
• [e.g. Always return { success: boolean, data?, error? }]
• [e.g. Never expose raw error messages to the client]

• [e.g. Never query the DB directly from a component — always through a service layer]
• [e.g. Always scope queries to the current user — never fetch without a user filter]
• [e.g. Use transactions for operations that touch more than one table]

• [e.g. Never use empty catch blocks — always log or handle]
• [e.g. User-facing errors must be human readable]
• [e.g. Log errors with a context prefix: [module/function]]

• [e.g. No comments explaining what the code does — code must be self-explanatory]
• [e.g. Comments only for why — explaining a non-obvious decision]
