# Messages Clean When this skill is invoked, do not add a preamble or narrate the plan. Run the relevant script directly, then return only the formatted result or the shortest actionable message. Resolve `PLUGIN_ROOT` from this selected skill's installed source path: it is the directory two levels above this `SKILL.md`. Use that absolute path; never infer it from cwd or hardcode a marketplace cache version. 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; otherwise ask a direct blocking Yes/No question. Put cancellation first and mark it recommended. Missing or ambiguous answers cancel. 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 never add `--apply` yourself. Only after explicit confirmation, run: ```bash bash "$PLUGIN_ROOT/scripts/clean-messages.sh" <confirmed filters including --apply> ``` Supported filters are `--older-than`, `--sender`, and `--recipient`. Never honor `--apply` without the separate confirmation. Report cancellation or the deleted count and bytes.
