At a glance

Undo a bad change without nuking unrelated work. An agent skill from Archive228/loopkit.

  • A specific commit
  • Calls git
  • Change broke something

What it does

Revert Surgical is an agent skill from Archive228/loopkit. Undo a bad change without nuking unrelated work. Use when a specific commit or change broke something.

Its SKILL.md is about 210 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 Development. It works with Git. The repository describes itself as: 33 battle-tested skills + minimal .claude harness for any coding agent (Claude Code, Cursor, Codex, Gemini CLI). The licence is MIT.

When your agent uses it

  • A specific commit
  • Change broke something

Example prompts

  • “/revert-surgical”

What it can do on your machine

Read from SKILL.md and the folder at commit 5ae033e. 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

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

  • Network

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

Revert Surgical loads about 211 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 87 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~211

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.

Surgical Revert

Don't git reset --hard away three good commits to undo one bad one.

  • Single commit — git revert <sha> creates an inverse commit; history stays intact and shared-branch-safe.
  • One file from a commit — git checkout <good-sha> -- path/to/file.
  • Hunk-level — git checkout -p to revert specific changes, keep the rest.
  • A merge — git revert -m 1 <merge-sha> (pick the mainline parent). On a shared branch, always revert (forward), never rewrite history. Reproduce the breakage first so you revert the RIGHT thing, then verify the revert actually fixes it.
