What it does

Jev Walk is an agent skill from xD3I/PZ_Optimization. Walk the player through a building with Jev directing (explore=mirror director=jev) on the collision-free game walk (pzopt.Nav), set up test rooms (mirrors in the corners, placed tiles), capture the walk and judge it (navjudge.py, walkframes.py). Use for any visual test that needs the character moving around a place (mirrors, lighting, cutaway, flicker), or when a walk rig collides, gets stuck or vaults fences.

Its SKILL.md is about 1.8k 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 Lua. The repository describes itself as: Project Zomboid Build 42 performance work: class overrides, harness, findings.

When your agent uses it

  • Any visual test that needs the character moving around a place (mirrors
  • A walk rig collides

Example prompts

  • “/jev-walk”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. A run
  2. Judge the walk
  3. Look at the walk

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

    Shell commands in SKILL.md call:

    • python3

    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

Jev Walk loads about 1.8k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 788 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~106
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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 788 words (~1,760 tokens).

“Since 2026-10-08 the walk never uses movement keys or teleports: pzopt.Nav issues the game's own "walk to" (ISWalkToTimedActionF, harness Lua harness/mod/pzopt-harness/42/media/lua/client/pzopt_harness_walk.lua), so the pathfinder routes round furniture footprints, takes stairs and opens doors. On top of that Nav:”
