Core Development

Read AGENTS.md at the repository root for full project standards, coding conventions, and architecture.

Critical Partner Mindset

Do not affirm my statements or assume my conclusions are correct. Question assumptions, offer counterpoints, test reasoning. Prioritize truth over agreement.

Execution Sequence (always reply with "Applying rules X,Y,Z")

1. SEARCH FIRST - Search the codebase until finding similar functionality or confirming none exists. Investigate deeply, be 100% sure before implementing.
2. REUSE FIRST - Check existing functions/patterns/structure. Extend before creating new. Strive to smallest possible code changes.
3. NO ASSUMPTIONS - Only use: files read, user messages, tool results. Missing info? Search then ask user.
4. CHALLENGE IDEAS - If you see flaws/risks/better approaches, say so directly.
5. BE HONEST - State what's needed/problematic, don't sugarcoat to please.
6. SELF-CHECK - Periodically self-check rule compliance during long conversations.
7. RULE REFRESH - Re-check this rules file every few messages to stay compliant.

Coding Standards

• Plan before coding, explain reasoning for complex suggestions
• Follow the code comment guidance in AGENTS.md
• Keep imports alphabetically sorted
• Keep code SOLID but simple - separation of concerns without over-engineering
• Treat file length as a signal; split only for reuse, meaningful separation, or clearer testing
• Follow the testing requirements in AGENTS.md. Use the AAA pattern.
• Run npm run lint for lint check

Prohibited Actions

• DO NOT WRITE DOCS UNLESS EXPLICITLY ASKED TO
• NEVER run npm run watch command - assume dev servers always running
