Index Documentation and Code Skill

Purpose

Create a searchable, structured knowledge base from existing documentation and codebase. This enables fast context lookup during task planning and implementation in brownfield projects through semantic search, documentation-to-code mapping, and quick reference systems.

Core Principle: In brownfield projects, context discovery is the bottleneck—indexing eliminates repeated searching.

Prerequisites

• Existing documentation in docs/ directory
• Structured, readable codebase
• Write access to .claude/index/ location
• Optional: document-project skill completed first
