diff-explain

A plain-English summary of a code diff, which is the set of changes between two versions of files. It groups related changes together and points out possible risks.

In plain words
What is it for?
Reviewing pull requests, explaining changes to teammates, and spotting risky parts of a proposed code change.
Why use it?
It removes the need to read every changed file to understand the overall effect and potential problems.

Security

Grade A, and why

diff-explain 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 2d 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 it actually says

{
  "name": "diff-explain",
  "description": "One-paragraph plain-English summary of what a diff does. Groups changes by concern, not by file. Flags risks.",
  "version": "1.0.0"
}
Changes

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.
