olk — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited olk (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

Every scanned point with the score it earned and what moved between them.
First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Use olk for Outlook Mail/Calendar/Contacts/Tasks and OneDrive files — as CLI commands (this guide), or as an MCP server (olk mcp) for tool-calling agents. Works with personal Microsoft accounts and enterprise Azure AD/Entra ID.
