Cowork の env 伝播を再検証する probe です。frontmatter hook を SessionStart と PreToolUse の両方で仕掛けてあります。
echo "[BODY] ROOT=[${CLAUDE_PLUGIN_ROOT:-(unset)}] DATA=[${CLAUDE_PLUGIN_DATA:-(unset)}] PROJECT=[${CLAUDE_PROJECT_DIR:-(unset)}] ENTRY=[${CLAUDE_CODE_ENTRYPOINT:-(unset)}] HOST=[$(hostname)]"
画面に出た以下の行をすべて貼ってください。
[PLUGIN-HOOK SessionStart] ...（plugin-level hook、session 開始 / resume 時）[PLUGIN-HOOK PreToolUse] ...（plugin-level hook、bash 直前）[FRONTMATTER-SessionStart] ...（この skill の frontmatter hook、SessionStart 経路）← 今回の主役[FRONTMATTER-PreToolUse] ...（この skill の frontmatter hook、PreToolUse 経路）[BODY] ...（skill body の bash）[FRONTMATTER-SessionStart] 行が出れば frontmatter hook の env を直接観測できます。ROOT 等が空かどうかで判定します。
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.
