Agent Skills — Pre-Built Workflows for AI Coding Agents

10 pre-built agent skills that compose act's 183 refactor operations, 30 codebase analyzers, 15 query operations, and 8 porting operations into common engineering workflows: architecture-audit, code-review, refactoring, code-navigation, code-generation, migration-assessment, boundary-analysis, change-impact, health-check, and architectural-refactoring. Invoke with /skill-name in Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent.
