  • Modifying the PeppyMeter window

What it does

Peppymeter is an agent skill from ad-repo/nullplayer. The PeppyMeter analog VU meter window — a skinnable needle/bar meter (port of project-owner/PeppyMeter) in classic + modern UI. Covers the meters.txt geometry, the CoreGraphics compositor (needle rotation + linear masks), the stereo-tap level model, meter selection/random, bundled GPL assets, and WindowManager integration. Use when modifying the PeppyMeter window, its renderer, meter templates, or level plumbing.

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: nullPlayer is a free open source macOS media player with some unique features.

When your agent uses it

  • Modifying the PeppyMeter window
  • Meter templates

Example prompts

  • “/peppymeter”

What it can do on your machine

Read from SKILL.md and the folder at commit 3d87ce1. 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

    Links to these hosts (documentation or services it may open):

    • github.com

    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

Peppymeter loads about 2.9k tokens when it runs. Until then it costs about 107 tokens; SKILL.md has 1,210 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~107
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,210 words (~2,852 tokens).

“A skinnable analog VU meter window — a native Swift port of project-owner/PeppyMeter. It renders left/right audio levels on classic analog needle (circular) and bar (linear) meters composited from bundled image templates. Two implementations (classic/modern UI) share one mode-neutral engine…”
