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.

このプラグインの plugin-level SessionStart hook が、session 開始時に 5 種類の echo を実行して結果を context に注入しています。直前の context（system-reminder / additional context）から、以下のプレフィックスで始まる行を探して、一字一句そのまま全部貼ってください。無い種類は「無し」と答えてください。
EXP_CONTROL= （変数なしの対照）EXP_TOP_DOLLAR= （top-level echo $PATH）EXP_TOP_BRACE= （top-level echo ${PATH}）EXP_BASH_DOLLAR= （bash -c 'echo $PATH'）EXP_BRACKET_ または [[ -d /tmp ]] を含む行 （top-level の bash 構文）判定の見方：
EXP_TOP_DOLLAR が実際の PATH 値なら top-level でシェル展開が効いている。$PATH という literal のままなら展開されていない。EXP_BASH_DOLLAR が実 PATH 値なら bash -c 経由では展開が効く。[[ -d /tmp ]] && ... の literal で出ていれば、top-level の bash 構文が評価されていない。
