SBH — storage pressure specialist

SBH exposes disk-pressure status, ballast, scanning, and recovery commands. This skill gathers evidence and performs at most the explicit action authorized by the caller. Its authorized actions can delete files and change host storage configuration, so no mutation runs without explicit caller authority. The command surface below is anchored to sbh 0.4.27; re-verify against sbh --version on another host before relying on an exact flag.

Evidence-first recovery works because disk pressure has cheap reversible remedies and expensive irreversible ones; a factual baseline is what tells them apart before anything is deleted. Order remediation by irreversibility: status and dry runs first, ballast release next, cleanup of unprotected files after that, and emergency deletion last — never skip forward while a more reversible step remains untried.

Named failure mode — wrong-mount relief: reclaiming gigabytes on a filesystem that is not the constrained mount and declaring the pressure resolved.

Anti-pattern: escalating straight to emergency --yes because pressure is critical. Corrective: urgency raises the stakes of an irreversible mistake; it never lowers the authorization bar or the ordering above.

Constraints

Begin with sbh --json status, sbh check, or a dry run on the exact mount because recovery decisions need a factual baseline.
Never run clean --yes, emergency --yes, ballast release, tune --apply, unprotect, or service/configuration changes without explicit authority because those operations mutate host state.
Preserve .git/, open-file, young-file, non-writable-parent, and .sbh-protect vetoes because they prevent unsafe or ineffective cleanup.
Confirm that ballast or reclaimed bytes affect the constrained mount because free space on another filesystem does not resolve the pressure.
Run one action once, capture before/after evidence, and stop because the caller owns any further mutation. A negative result is returned to the caller; this skill does not retry or escalate it.

Output

Return mount, free bytes, pressure state, dry-run candidates, authorization used, exact command and exit code, bytes reclaimed, protection vetoes, and checked/not checked surfaces.
