Mac Cowork で、plugin-level SessionStart hook(host 側)から $CLAUDE_PLUGIN_DATA に書いた値が「別の chat session を跨いで」残るかを検証する probe。書き込み＆読み戻しは hook(persist.sh)側で行い、その結果は SessionStart の stdout として context に出る。この skill body は対比用に「VM Bash 側から DATA が見えるか／hook が書いたファイルを読めるか」を確認する。
Surfaces UPE_PROBE_* marker lines to test whether the plugin-level UserPromptExpansion hook fires on Cowork. Invoking this skill via slash is itself the trigger; compares against UserPromptSubmit and SessionStart controls.
Triggers the plugin-level PreToolUse hooks by running a sentinel bash command, to test (via session export) whether Cowork runs PreToolUse hook commands through cmd.exe or a POSIX shell, and whether the inline block pattern actually blocks the bash tool.
Surfaces the EXEC_* marker lines emitted by the plugin-level SessionStart hooks, which run hook commands in EXEC FORM (args present). Used to test whether exec form resolves ${CLAUDE_PLUGIN_ROOT} to a real path and exports it as an env var on Cowork, where shell form (§2.1/§2.2) failed both.
Shows what skill-body CLAUDE_PLUGIN_ROOT and friends substitute to on Mac Cowork, whether the VM Bash tool can use that path, and whether the Read tool can read a bundled file at that host path.
Proves whether a skill frontmatter PreToolUse Bash hook fires on Cowork by emitting only a block decision (no echo). A marked bash should be blocked even though no frontmatter stdout surfaces.

§1.5 — 4 trigger ルートを観察。完全手動 probe。
手順は MASTER-RUNBOOK の 05 セクションを参照してください。SKILL では log 確認だけ：
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 '[05-BODY %s] tag=alive-check\n' "$(date -Iseconds)"
printf '[05-BODY] hello=[%s] secret=[%s]\n' "${CLAUDE_PLUGIN_OPTION_HELLO_MESSAGE-(unset)}" "${CLAUDE_PLUGIN_OPTION_API_SECRET-(unset)}"
} | tee -a "$out_dir/probe.log"
echo "=== install.log: search for 'Plugin option ... isn't set' ==="
grep -nE "Plugin option.*isn.t set|Plugin option.*is not set" "$proj/findings/$ver/install.log" 2>&1 || echo "(no hook error in install.log — userConfig may already be set)"
echo
echo "=== settings.json pluginConfigs ==="
cat "$CLAUDE_CONFIG_DIR/settings.json" 2>&1 | head -40
完了して exit、./scripts/assert.sh 05（半自動）。
