§2.8 — CLAUDE_PLUGIN_ROOT/DATA の 3 形式。

step 1: skill body 経路で alive-check と path 観察

proj="${CLAUDE_PROJECT_DIR:-$PWD}"
ver="${VERIFIER_VERSION_DIR:-v-unknown}"
sid="${CLAUDE_SESSION_ID:-no-sid}"
out_dir="$proj/findings/$ver/$sid"
mkdir -p "$out_dir"
{
  printf '[16-BODY %s] tag=alive-check\n' "$(date -Iseconds)"
  printf '[16-BODY BODY_SUBST] ROOT=[${CLAUDE_PLUGIN_ROOT}] DATA=[${CLAUDE_PLUGIN_DATA}]\n'
  printf '[16-BODY BODY_ENV] ROOT=[%s] DATA=[%s]\n' "${CLAUDE_PLUGIN_ROOT-(unset)}" "${CLAUDE_PLUGIN_DATA-(unset)}"
} | tee -a "$out_dir/probe.log"
echo
echo "=== 3 forms of ROOT/DATA in probe.log ==="
grep -E "BODY_SUBST|HOOK_SUBST|HOOK_ENV" "$out_dir/probe.log"

完了して exit、./scripts/assert.sh 16。
