§1.8 — skill frontmatter SessionStart + once:true は不発、PreToolUse は invoke 後の bash で発火。
step 1: alive-check と log 確認
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 '[08-BODY %s] tag=alive-check\n' "$(date -Iseconds)" | tee -a "$out_dir/probe.log"
echo
echo "=== probe.log (SessionStart canary entries should be absent) ==="
grep -E "08-FM-SESSIONSTART|08-FM-PreToolUse" "$out_dir/probe.log" 2>&1 || echo "(no 08-FM lines)"
echo
echo "=== hooks.log (plugin-level session-start should be present) ==="
grep -c "tag=session-start" "$out_dir/hooks.log" 2>&1 || echo "0"
完了して exit、./scripts/assert.sh 08。
