Use this skill whenever handing off a build task to Claude Code for the HAIP project. Trigger on "hand off to Claude Code", "build this", "code this module", "Claude Code brief", or whenever an approved spec or phase needs to go to the builder. HAIP builds follow HAIP rules — PROJECT_INSTRUCTIONS.md as constitution, no invented domain logic, TypeScript/Node/pnpm/NestJS stack.
Query the HAIP knowledge base for hotel PMS domain knowledge. Use whenever you need hotel operations facts, PMS architecture patterns, integration standards, compliance requirements, or competitive analysis. Trigger on any hotel domain question — check the KB before asking Dušan or inventing answers.
Research hotel PMS domain knowledge from authoritative sources. Use whenever the KB has gaps, a domain question comes up that can't be answered from existing knowledge, or when competitive intelligence needs updating. Trigger on "research this", "what does the industry say about", "find out how hotels handle", or any domain question not covered in HAIP_KNOWLEDGE_BASE.md.
Use this skill whenever writing or revising a module specification for HAIP. Trigger on "write spec for", "spec out module", "define module", or whenever a phase from HAIP_BUILD_PLAN.md needs detailed specification before going to Claude Code. Every HAIP module must go through this template before build.
