At a glance

Diagnose or change how the MangoHud HUD and CSV log attach to the game across launchers (Steam, direct), renderers (NVIDIA GL, Zink) and display servers (X11, native Wayland).

  • A run has no mangohud CSV
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • The log window is wrong

What it does

Mangohud Overlay is an agent skill from xD3I/PZ_Optimization. Diagnose or change how the MangoHud HUD and CSV log attach to the game across launchers (Steam, direct), renderers (NVIDIA GL, Zink) and display servers (X11, native Wayland). Use when a run has no mangohud CSV, no overlay, or the log window is wrong.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering CSV and tabular files. It works with NVIDIA AI Platform. The repository describes itself as: Project Zomboid Build 42 performance work: class overrides, harness, findings.

When your agent uses it

  • A run has no mangohud CSV
  • The log window is wrong

Example prompts

  • “/mangohud-overlay”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 5a0a992. 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.

    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

Mangohud Overlay loads about 493 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 214 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~493

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 214 words (~493 tokens).
