What it does

Inspect Disk is an agent skill from felixrieseberg/windows95. Inspect or modify the Windows 95 disk image offline with mtools — no QEMU, no Electron, no boot. Use when checking what's on the C: drive, extracting/reading files from the image, copying files into it, or verifying image contents after a change.

Its SKILL.md is about 1.3k 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: Windows 95 in an app. Runs on macOS, Linux, and Windows.

When your agent uses it

  • Checking whats on the C: drive
  • Extracting/reading files from the image
  • Copying files into it
  • Verifying image contents after a change

Example prompts

  • “/inspect-disk”

What it can do on your machine

Read from SKILL.md and the folder at commit 051065e. 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:

    • yarn

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

  • Network

    No URLs in SKILL.md. Its commands use yarn, 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

Inspect Disk loads about 1.3k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 593 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 593 words (~1,311 tokens).

“images/windows95.img is a 1 GB raw MBR disk with a single FAT32 (0x0C) partition starting at sector 63. mtools (installed via Homebrew) can read and write it directly — the only trick is the partition byte offset:”
