From SENTINEL — Security & Privacy Gate
Verify that SENTINEL's security scanners are installed and reachable — SCA (npm audit, pip-audit, cargo-audit, osv-scanner), secrets (gitleaks), and the Semgrep MCP for SAST. Trigger with /sentinel:check (or "check sentinel prerequisites", "which scanners are installed?"). Runs a fast ✓/✗ probe grouped by tier. Advisory by default (SENTINEL degrades gracefully — a missing scanner narrows a lens to partial coverage, never a false PASS); pass --strict to fail on a missing required tool. Reads the canonical manifest skills/check/requirements.tsv.

report the gap rather than passing silently. Each ✗ prints its install hint (the local source
