Substitute that absolute path literally for `<PLUGIN_ROOT>` below; never infer it from the working directory or hardcode a marketplace cache version. `SESSION_SCHEDULER_HOME` must already be present in this pane's environment, inherited when the agent process started (the pane/session launcher sets it — never export or derive it here).

If the script reports the variable is not set, stop and request a pane relaunch with the correct environment instead of deriving another ledger. Always preview first, stripping `--apply` from the script invocation and showing the exact candidates. If the preview has no candidates, report that and stop. If (and only if) `--apply` was in the user's original arguments, ask for explicit confirmation. Use structured `request_user_input` when available in the current mode; otherwise ask a direct blocking Yes/No question. Put cancellation first and mark it recommended. Default, missing, or ambiguous answers cancel deletion. When the original arguments did not contain `--apply`, stop after the preview and tell the user to invoke the skill again with `--apply` if they want to delete. Do not prompt and n
