# get-identity.sh — Read identity.json and export user/machine vars for attribution
#
# Source this at the start of any skill that needs attribution (bot alerts, commits,
# logs, RMM operations). Exports $USER_NAME, $USER_SHORT, $MACHINE, $USER_EMAIL.
#
# Usage:
#   source .claude/scripts/get-identity.sh
#   echo "[RMM] $USER_SHORT deployed to X machines..."
#
# Soft-fails: if identity.json is missing, exports "Unknown" values and returns 1
# (but does NOT exit, so the caller continues). This ensures skills never break on
# missing identity - they just attribute to "Unknown".

# Resolve the repo root from this script's own location (mirrors vault.sh) so callers
# don't have to know it. An already-set CLAUDETOOLS_ROOT still wins, and identity.json's
# claudetools_root overrides both. Never hardcode a drive letter.
