At a glance

Explain how the code on the current branch works, as an HTML page opened in the browser, written so someone can understand the change and review it.

  • Asked to explain a branch
  • SKILL.md covers Scope, Read beyond the diff, How to write it and Link to the code, plus 1 more section
  • Calls git and gh; reaches github.com
  • Explain these changes

What it does

Explain Changes is an agent skill from freekmurze/dotfiles. Explain how the code on the current branch works, as an HTML page opened in the browser, written so someone can understand the change and review it. Use when asked to explain a branch, explain these changes, walk me through this code, help me review this, or explain what an agent just did. Most useful when someone other than the reader wrote the code and it has to be understood before merging.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files.

It sits in Frontend & Design, covering HTML artifacts.

When your agent uses it

  • Asked to explain a branch
  • Explain these changes
  • Walk me through this code
  • Help me review this

Example prompts

  • “/explain-changes”

What it can do on your machine

Read from SKILL.md and the folder at commit 296be1a. 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:

    • git
    • gh

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • 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

Explain Changes loads about 1.8k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 1,025 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.8k

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 1,025 words (~1,803 tokens).

“Produce a detailed written explanation of everything on this branch, as an HTML page, and open it.”
