get_score
Fast static Umbra Trust Score (0-100) for a repository — SAFE and CLEAN axes only, no network, no sandbox. Use scan_repo for the full report with findings.
guard_content
Check a proposed file write against the Umbra guard engine BEFORE writing. Returns the guard verdict as JSON: decision (allow/warn/block), findings with file:line evidence, and pathViolation when a protected path (e.g. .git/hooks) is targeted. On block, do not write — fix the content and re-check.
scan_repo
Scan a repository and return the full Umbra Trust Score report as JSON (SAFE/CLEAN static findings; deep=true also verifies RUNS and HONEST in a Docker sandbox). Call before declaring a task done — a score below 50 means the work is not done.
