At a glance

Prepare and run the Windows/Proton comparison build of Project Zomboid.

  • Asked to compare native Linux against Proton
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Resume the prepared Proton run

What it does

Proton Run is an agent skill from xD3I/PZ_Optimization. Prepare and run the Windows/Proton comparison build of Project Zomboid. Use when asked to compare native Linux against Proton, or to resume the prepared Proton run.

Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Linux. The repository describes itself as: Project Zomboid Build 42 performance work: class overrides, harness, findings.

When your agent uses it

  • Asked to compare native Linux against Proton
  • Resume the prepared Proton run

Example prompts

  • “/proton-run”

What it can do on your machine

Read from SKILL.md and the folder at commit f6eb39a. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

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

  • Network

    No URLs in SKILL.md.

    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

Proton Run loads about 329 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 113 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~329

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 113 words (~329 tokens).

“State (2026-09-19): prepared, not launched. The Windows depot is not on disk; Steam keeps one platform depot and swaps it with the compat tool. Forcing a Proton tool in Steam > Properties > Compatibility (which removes the native depot) is…”
