 - Keep messages short and clear.
 - Keep help concise, usage-first, and warning-focused.
 - Preserve the fallback wipe flow: secure discard, zero discard, then `dd` zero-fill.
+- Keep optional tools optional.
+- Use extra wipe methods only if the command is present.
+- Use `ddrescue` or `dd_rescue` only after `dd` fails.
+- Keep `nvme-cli` and `hdparm` optional.
+- Use `nvme` and `hdparm` only on matching device types.
+- Do not make new external tools required.
 - Keep changes minimal and preserve intent.
 - Keep `./continue/rules/project.md` aligned and concise.
 - If non-interactive support is added, make it an opt-in safety flag.
