v0.3.1 - Specialist Roles (UX, Performance, Security)

Added

• 3 new roles: ux-engineer, performance-engineer, security-engineer

Changed

• AGENTS.md roles table expanded from 8 to 11 roles

Removed

• Root-level monolithic agent prompts (design.md, performance.md, security.md) - content decomposed into roles, skills, and workflows

v0.3.0 - DT to Spec rename, layer-prefixed structure

Removed

• docs/dt/ directory and docs/dt-lifecycle.md

• New rule security - secrets, input validation, prompt security, Docker security, auth
• New context template mcp-sdk - MCP Python SDK quick reference
• New context template a2a-sdk - A2A Python SDK quick reference
