What it does

Tsz Disk Cache Hygiene is an agent skill from tsz-org/tsz. 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.

Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/cleanup-ladder.md`).

It sits in Development, covering Git worktrees. It works with Rust and TypeScript. The repository describes itself as: An experiment in fully hand-off software engineering: A performance-first TypeScript checker. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Git worktrees

Example prompts

  • “/tsz-disk-cache-hygiene”

What it can do on your machine

Read from SKILL.md and the folder at commit 153b25a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tsz Disk Cache Hygiene loads about 342 tokens when it runs, and up to ~822 if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~342
With references · SKILL.md plus every file in references/, read only if the agent opens them
~822

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

bash
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:

bash
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.
