| description | Prevent TSZ machines and worktrees from running out of disk while preserving useful build caches. Use before creating worktrees, running large builds/tests, diagnosing low disk, cleaning artifacts, deciding whether to delete caches, or recovering space without slowing future Rust/TypeScript builds. |
TSZ Disk Cache Hygiene
Use when disk, cleanup, or new worktrees are involved. Preserve hot caches unless
the machine is at risk.
Compact Checks
df -h .
scripts/setup/disk-worktree-guard.sh
scripts/agents/disk-preflight.sh
git worktree list
Reuse inactive sister worktrees before creating new ones.
Cleanup Ladder
If low disk:
scripts/setup/disk-worktree-guard.sh --auto-prune
scripts/setup/clean.sh --quiet
Rerun the guard. Read references/cleanup-ladder.md before deleting worktrees,
running scripts/setup/clean.sh --full, or manually removing build dirs.
Preserve
Keep .target/, .target-bench/, target/, populated/symlinked
TypeScript/, and package-manager caches unless corruption or emergency space
pressure proves otherwise. Do not run cargo clean, rm -rf target, or full
clean as routine hygiene.
Report only before/after guard summary, caches preserved/destroyed, and why any
worktree/cache removal was safe. Avoid giant recursive size listings.
