commit-archaeology-red-flags

commit-archaeology-red-flags is a skill for Claude Code from maxrave-dev/kotlin-footguns. It costs 105 tokens per session (1,895 once invoked), scanned A, original, GPL-3.0.

A guide to reading a repository’s Git history to understand why changes were made. It explains how empty commits, nested-repository updates, and merge commits can hide important details.

In plain words
What is it for?
Use it when investigating when a change happened, why a design was chosen, what a nested repository update contains, or how a branch’s work was combined.
Why use it?
A commit’s title alone may not show the real change or decision behind it. The guide helps reconstruct the history without mistaking summaries, pointers, or merges for the full story.

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

commit-archaeology-red-flags scanned grade A with 0 findings 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 8d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
