Canonical Skill

This root file is a compatibility redirect. The canonical AI SAFE² v3.1 skill is:

skills/ai-safe2-secure-build-copilot/SKILL.md

Use that file for current framework guidance.

AI SAFE² v3.1 retains 161 core controls and adds the current CP.5.MCP profile overlay with MCP-1 through MCP-19, aligned to MCP 2026-07-28.

The core control dataset remains skills/mcp/data/ai-safe2-controls-v3.0.json because the v3.1 release did not change the core 161-control taxonomy. The v3.1 MCP overlay is skills/mcp/data/mcp-profile-v3.1.json.

v3.1 Changes Relevant to the Skill

• Three enforcement planes: north-south, east-west, and agent-to-tool.
• Protocol-independent governance constructs.
• MCP 2026-07-28 profile alignment.
• MCP-14 through MCP-19.
• Canonical persistence scopes: request, handle_scoped, durable.
• NEXUS explicitly positioned as CSI's reference implementation rather than a mandatory dependency.
• MCP-19 intended-resource/audience and SSRF requirements.
• server/discover is optional, not a conformance presence requirement.

Historical v3.0 additions such as CP.1 through CP.10, HEAR, Agent Replication Governance, and the 161-control core taxonomy remain part of v3.1.
