awesome-git-history-reset

awesome-git-history-reset is a skill for Claude Code from khasky/awesome-agent-skills. It costs 116 tokens per session (4,362 once invoked), scanned A, original, MIT.

A controlled process for replacing a repository's entire Git commit history with one new commit while keeping the current files. Git history is the record of changes that a repository and its collaborators normally rely on.

In plain words
What is it for?
Use it when you explicitly need to wipe a repository's history, create a single initial commit, and publish that rewritten history safely.
Why use it?
It can remove an unwanted public history, but the operation is irreversible on the remote and can disrupt clones and pull requests. The process checks access, makes a verified backup, scans for secrets, and requires confirmation before force-pushing.

    Fix: Remove the malware payload or compromised file entirely. Investigate how it entered the skill and audit all other artifacts for additional indicators of compromise.

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

awesome-git-history-reset scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git History Reset

Collapse a repository's entire history into one fresh Initial commit and force-push it, so the published commit log starts clean. The file tree is preserved byte-for-byte; only the history leading to it is discarded.

Why the ceremony: this is an irreversible, outward-facing rewrite of a shared remote. Once you force-push, every old commit on the default branch is gone from the tip, open pull requests break, and anyone who cloned or forked keeps the old history anyway. The steps below are not bureaucracy — each one closes a specific way this goes wrong: pushing without write access, discovering too late that the branch was protected, losing content in the squash, or force-pushing over a teammate's commit you never saw.

Core principle

NOTHING IRREVERSIBLE UNTIL FOUR THINGS HOLD: write access is confirmed, a mirror backup exists and is verified, the history is scanned for secrets, and the user has explicitly confirmed the wipe. If any one is missing, stop at that gate.

Three invariants hold throughout:

  • Never operate on the user's existing checkout. Always work in a fresh clone in a scratch directory. If the push fails or the result is wrong, the scratch clone is disposable and the user's own working copy was never touched.
  • Never assume the default branch is main. Detect it from the remote. Rewriting the wrong branch, or one that isn't the default, silently leaves the real history in place.
  • Never delete the backup, and never delete a remote ref, without asking. The backup is the only rollback path. Extra branches and tags may be the user's, not stale.

Invocation

/awesome-git-history-reset <repository-url> [branch] [--message "Initial commit"]
  • <repository-url> — required. HTTPS or SSH (https://github.com/owner/repo.git or [email protected]:owner/repo.git).
  • [branch] — optional. Defaults to the remote's detected default branch. Only pass this to target a non-default branch.
  • --message — optional. The single commit's message. If omitted, Phase 0 asks for it at preflight (default Initial commit).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
